Exterior cleaning quote template UK: how to price window cleaning, pressure washing and softwash

Q: What is the going rate for pressure washing per square metre in the UK?

UK pressure washing rates in 2026 typically range from £3–£8 per square metre depending on surface type and condition. Block paving (most labour-intensive due to sand joints and weed growth): £5–£8/m². Concrete driveways and paths: £3–£5/m². Patios (Indian sandstone, porcelain): £4–£7/m². Rendered walls and fascias: £4–£6/m². Always add a mobilisation charge of £25–£75 for one-off jobs to cover travel, machine setup, and water sourcing. Minimum job price of £80–£120 prevents uneconomic small jobs.

Q: Is softwash more expensive than pressure washing?

Yes — softwash is typically 30–60% more expensive than pressure washing for the same surface area. The higher price reflects the cost of biocidal chemicals (sodium hypochlorite, surfactants, growth inhibitors), dwell time (often 20–40 minutes on roofs and facades), rinsing, and the environmental risk management required — bunding, plant protection, drainage controls. Softwash is the correct method for roofs, render, pebbledash and sensitive surfaces where high-pressure water would cause damage. Quote it as a separate service with chemical cost built in, not as a variation of pressure washing.

Q: How do I quote for roof cleaning in the UK?

Roof cleaning in the UK is almost always softwash rather than pressure washing — high-pressure water dislodges pointing, cracks tiles, and voids some roof warranties. Price roof softwash by the roof area (measure length x width of each pitch): typical UK rates in 2026 are £8–£15 per square metre. Add: a scaffolding or MEWP (mobile elevated work platform) cost if needed, an environmental risk premium (£50–£150) to cover bunding and plant protection for chemical runoff, and a treatment guarantee (biocide works over 6–24 months; include one free re-treatment or a paid maintenance visit in your quote). Always require public liability insurance of at least £2 million for roof work.

Q: Should I charge a mobilisation fee for exterior cleaning jobs?

Yes — always charge a mobilisation fee for one-off exterior cleaning jobs. Mobilisation covers the time and cost of loading equipment, travelling to site, filling tanks (for reach-and-wash or softwash), setting up, and returning. A reasonable mobilisation charge in 2026 is £30–£75 for residential jobs and £75–£200 for commercial or multi-day jobs. Present it as a transparent line item on your quote — most clients accept it because it makes sense. Do not absorb mobilisation into your per-square-metre rate: it makes your rate look expensive on large jobs and uneconomic on small ones.

Q: How do I add gutter clearance as an upsell on a window cleaning round?

Gutter clearance is the highest-conversion upsell on a window cleaning round because you are already on site with ladders or a reach-and-wash system. Price it per linear metre of guttering (typical UK rate: £2–£4/m) or as a flat per-property rate (£45–£90 for a 3-bed semi). Offer it as an annual add-on: 'I can clear your gutters once a year in autumn as an add-on to your window round for £[X].' Most window cleaning clients say yes because they do not want to deal with gutters themselves. Invoice it separately or as a line item on the same quote to make the value clear.

Exterior cleaning is the sector where underquoting does the most damage. A window cleaner who forgets to account for reach-and-wash equipment depreciation loses money on every round. A pressure washer who doesn't charge mobilisation on one-off jobs works half the day for free. A softwash operator who ignores chemical cost and dwell time quickly discovers that their margins have been eaten alive by sodium hypochlorite and petrol.

The complexity doesn't show up on a basic quote. An exterior cleaning quote for a residential property looks simple on the surface: a service, a price, a date. But behind that number sits a chain of costs and variables — access constraints, surface types, environmental controls, weather risk, equipment wear — that a well-constructed quote must account for, visibly or invisibly, to protect your business.

This guide covers how to price each major exterior cleaning service correctly, what a professional exterior quote must contain, and includes a complete ready-to-use quote template. It is written for cleaning businesses operating across England, Scotland and Wales in 2026.

Why exterior cleaning quotes need to be different

Residential interior cleaning prices are driven primarily by property size, room count, and time. Exterior cleaning prices are driven by a completely different set of variables — and most of them are invisible until you are standing on site.

Variable access. The same driveway can take 30 minutes or two hours depending on whether your machine can reach it from the gate, whether vehicles need to be moved, and whether there is an external tap with adequate pressure. A terrace in inner-city Manchester may have no vehicular access at all — your hose reel adds £15 in time before you've started. Quote access difficulty explicitly.
Weather dependency. Pressure washing and window cleaning can often continue in light rain but not in frost, high wind, or heavy rain. Softwash cannot be applied if rain is forecast within 4–6 hours of application — the chemical washes off before it has time to work. Exterior quotes need a weather and cancellation policy that protects your income without penalising the client for uncontrollable conditions.
Equipment mobilisation. A domestic cleaning job requires a bag and products. A pressure washing job requires a trailer or van-mounted unit, high-pressure hose, lances, safety equipment, and often a dedicated water supply or buffer tank. The time and cost to mobilise this equipment are real and must appear somewhere in your pricing — either as a transparent mobilisation line item or baked into your rate, clearly understood by you even if not broken out for the client.
Chemical dilution and consumption. Softwash operators know this problem acutely: the chemical cost of treating a 100m² moss-covered roof can be £30–£80 depending on dilution ratios and the number of applications needed. If you have not calculated chemical cost into your per-square-metre rate, you are routinely delivering unpaid work. Chemical cost must be a first-class input in your pricing, not an afterthought.
Environmental controls. Pressure washing and softwash generate contaminated runoff — biocide-laced water, algae slurry, dislodged debris — that must be managed to comply with environmental legislation in England, Scotland and Wales. Bunding, drain blocking, and plant protection take time and add cost. A quote that doesn't account for environmental control work either absorbs that cost silently or leaves it undone, creating a legal and reputational risk.

⚠ The hidden cost problem in exterior cleaning

Most exterior cleaning underquoting happens not because operators set too low a rate per square metre, but because they fail to include the fixed costs around the job — mobilisation, setup, water sourcing, chemical prep, environmental protection, and pack-down. On a £120 pressure washing job these fixed costs can easily total £40–£60 in time and materials. If you only price the productive cleaning time, you are working at a significant loss on every job you quote.

How to price each exterior cleaning service

Window cleaning: per pane vs per property, frequency discounts, reach & wash vs traditional

Window cleaning is the one exterior cleaning service that benefits most from a regularised round structure. A window cleaner with a full round of regular clients — weekly or fortnightly properties within a tight geographic area — has a genuinely scalable business with predictable income. That structural advantage shapes how window cleaning should be priced.

Per property pricing is almost always preferable to per pane. Counting panes is slow, confusing for clients, and invites negotiation over every skylight and obscure fanlight. A per-property price, set after a site visit or clear brief from the client, is faster to quote, easier to explain, and simpler to collect. The rate should reflect the total number of accessible windows, the method required, and the frequency.

2026 UK pricing benchmarks for regular window cleaning (fortnightly round):

Property type	London / South East	Midlands / North	Scotland / Wales / Rural
1–2 bed flat / terraced	£12–£18	£8–£13	£6–£11
3-bed semi / terraced	£16–£22	£10–£16	£8–£13
4-bed detached	£22–£35	£15–£24	£12–£20
One-off clean (any)	1.5–2× regular round rate — no frequency income to average against

Reach-and-wash (pure water, extended pole system) commands a 10–20% premium over traditional methods in most markets. The premium is justified by the equipment investment (a quality reach-and-wash system costs £1,500–£5,000), the superior finish on upper-floor and difficult-access windows, and the health-and-safety benefit of working from the ground rather than a ladder. In London, Bristol, Birmingham and other competitive urban markets, reach-and-wash is increasingly the baseline expectation rather than a premium product — adjust your pricing accordingly.

Frequency discounts should be structured carefully. Weekly clients are significantly more valuable than fortnightly clients — a property never gets heavily dirty, visits are fast, and your income per property per year is roughly double. You can legitimately discount weekly rates by 10–15% relative to fortnightly to incentivise it, without losing profitability. Monthly cleaning is slower per visit and less reliably dirty — price it at 80–90% of fortnightly, not 50%.

Pressure washing: per sq metre, surface type, mobilisation charge

Pressure washing pricing is most cleanly expressed as a per-square-metre rate, adjusted by surface type and condition. The per-square-metre structure is easy to explain and simple to scale, and allows clients to understand exactly what they are paying for as the scope expands or contracts.

Surface type is the primary pricing variable in pressure washing. Different surfaces require different pressures, nozzles, techniques, and time investment:

Block paving: £5–£8/m². Most time-intensive. Weed growth in joints, sand displacement, potential sand reinstatement afterwards, high risk of joint erosion if pressure is too high. Leeds, Manchester and Birmingham have high volumes of block paved driveways — understand this market well.
Concrete driveways and paths: £3–£5/m². Faster than block paving, lower risk. Surface staining (oil, tyre marks) may require pre-treatment with degreaser — factor this into chemical cost.
Patios — Indian sandstone, porcelain: £4–£7/m². Sandstone requires lower pressure and often a biocide pre-treatment to avoid surface damage. Porcelain is more tolerant of pressure but joints need care. Both are slower than plain concrete.
Render and pebbledash walls: £4–£6/m². Requires careful pressure management to avoid surface damage, particularly on older or K-rend finish properties. Often better treated as softwash — discuss with the client.
Decking (timber): £4–£7/m². Low pressure essential. Often followed by decking oil or stain application, which is a separate chargeable service.

Always charge a mobilisation fee on one-off jobs. A reasonable mobilisation charge in 2026 is £30–£75 for residential jobs (covering trailer/van loading, travel, machine setup, water sourcing, and pack-down) and £75–£200 for commercial or multi-day jobs. Present it as a named line item on the quote — not hidden in an inflated per-square-metre rate. Most clients accept it when it is explained clearly. Set a minimum job value of £80–£120 to prevent uneconomic small-area one-offs.

Softwash: chemical cost, dwell time, rinse, roof vs facade, environmental risk premium

Softwash is the highest-margin exterior cleaning service when priced correctly — and the most commonly underpriced. The core issue is that chemical cost is variable, dwell time is non-productive waiting time that must still be charged, and environmental risk management adds a genuine cost that most operators don't quantify.

How to build a softwash price:

Measure the surface area. Length × width for flat surfaces; for pitched roofs, measure each pitch and multiply by the pitch factor (typically 1.15–1.3 for standard UK pitches).
Calculate chemical cost. Sodium hypochlorite at 10–12% concentration, diluted to working strength (typically 3–6% for roofs, 1–3% for facades). At current UK wholesale prices (May 2026), budget approximately £0.20–£0.40 per litre of working solution applied, plus surfactant and growth inhibitor. A 100m² roof might require 40–80 litres of working solution depending on application method and contamination level.
Add dwell time. Softwash needs 20–40 minutes on roofs (longer in cold weather — particularly relevant in Scotland and northern England in winter) before rinsing. This time is not productively used unless you have a second operative working elsewhere. Charge it. A reasonable dwell-time allowance is 30–45 minutes per application at your standard hourly rate.
Add rinsing time. A clean-water rinse after biocide application protects plants, prevents streaking, and speeds up the visible transformation. Budget 15–20 minutes per 100m².
Add environmental risk premium. Bunding drainage outlets, laying plant protection matting, briefing the client on what not to touch or walk on, and clearing up the protective equipment afterwards: budget £50–£150 per job depending on complexity. This is a real cost that many operators absorb silently and shouldn't.

2026 UK softwash rate benchmarks: Roof softwash — £8–£15/m² depending on pitch, access, and contamination level. Facade softwash (render, pebbledash, brick) — £5–£10/m². These rates include chemical cost and environmental controls; they do not include scaffolding or MEWP hire, which should be quoted as a separate line item.

Roof vs facade pricing: Roofs are more expensive per square metre than facades for three reasons — they require working at height (safety premium), they have higher chemical consumption due to deeper contamination, and the consequences of a mistake (damaged tiles, blocked gutters, injury) are more serious. Always quote roof softwash at the top of the rate range and present a treatment guarantee (biocide remains active for 12–24 months; include one follow-up inspection or a paid maintenance visit).

Gutter clearance: per linear metre or per property, add-on to window round

Gutter clearance is structurally the most opportunistic service in an exterior cleaning business — the demand is consistent (blockages happen in autumn across England, Scotland and Wales), the work is visible and satisfying for clients, and if you are already on site for window cleaning you have no incremental travel cost. It is the highest-conversion upsell in the exterior cleaning sector.

Pricing options:

Per linear metre: £2–£4/m for standard residential guttering. A typical 3-bed semi in Birmingham or Leeds has approximately 20–30 linear metres of guttering. At £3/m, that is £60–£90 per clearance visit.
Per property flat rate: £45–£90 for a standard 3–4 bed residential property. Simpler to quote and explain. Use this for first-time quotes where you haven't measured yet.
As an annual add-on to a window round: Offer gutter clearance once a year (autumn) at the per-property flat rate as a named add-on to your regular window cleaning contract. Most clients say yes because they do not want to deal with gutters themselves and trust you already.

Always inspect gutters from the ladder while cleaning windows — if you can see debris, downpipe blockages, or sagging, tell the client. A brief observation note ("I noticed your gutters are holding standing water — I can clear them on the next visit for £[X]") converts at a very high rate, particularly in autumn and after leaf fall across Bristol, Manchester, Leeds and similar urban areas with high tree canopy coverage.

What the exterior cleaning quote must include

An exterior cleaning quote has a larger footprint than a domestic cleaning quote because the scope is more complex, the risks are higher, and the conditions under which the job is completed are more variable. Every element below serves a specific protective or commercial purpose.

Property address and access notes. Include the full address and a brief access description: "Rear garden access via side gate, gate code [XXXX]. No on-site water supply — operator to bring tanked supply." Access notes protect you from a failed visit and set expectations before you arrive.
Services quoted — each as a separate line. Never bundle exterior cleaning services into a single line. Window cleaning, pressure washing, softwash, and gutter clearance are distinct services with distinct scopes. Separate lines allow the client to accept some services and decline others, and prevent any ambiguity about what is included.
Frequency and scheduling. For window cleaning rounds: the day of the round (e.g. "every other Thursday"). For softwash: the recommended treatment season (spring or autumn in England and Wales; late spring in Scotland where lower winter temperatures affect biocide activity). For pressure washing: one-off or annual, and approximate scheduling window.
Environmental protections. State what you will do: "Drainage outlets to be bunded during pressure washing. Plant protection matting to be laid prior to softwash application. Client to be advised on re-entry timescales." This demonstrates professionalism, satisfies environmental due diligence, and protects you legally if a neighbour or client claims damage from chemical runoff.
Payment terms. State clearly: payment due on completion, or within 7 days of invoice for regular round clients. For softwash and large one-off pressure washing jobs, a 20–30% deposit before the job date is reasonable and industry-standard. Include bank transfer details or payment method on the quote itself.
Weather and cancellation policy. Exterior cleaning is uniquely weather-dependent. A clear policy protects both parties: "In the event of frost, high winds (above 30 mph), or heavy rainfall, the operator reserves the right to reschedule without charge. Client cancellations with less than 24 hours' notice: 50% of quoted price. Softwash jobs cancelled on the day due to weather will be rescheduled at no additional charge within 14 days."

ℹ The written weather policy is your income protection

Exterior cleaning businesses in Scotland, Northern England and Wales lose more productive days to weather than those in the South East and Midlands. Without a written weather and rescheduling policy on every quote and booking confirmation, disputed cancellation charges are unenforceable. Write it down. Send it before every job. Reference it if a dispute arises.

Common exterior cleaning pricing mistakes

These are the most frequent errors that erode margin on exterior cleaning jobs across the UK. Most are invisible at point of sale — they only show up at the end of a job when you calculate what you actually earned per hour.

Underquoting access difficulties. A job that looks like a standard driveway on the phone turns out to have a locked side gate, a tight corner for the trailer, and vehicles parked across the working area. Access difficulty adds 20–40% to the time on a pressure washing job. Always ask about access before quoting, and build in an access premium for anything that isn't straightforward. Jobs in dense urban areas — inner-city London, central Manchester, Bristol terraces — almost always have access complications.
Forgetting chemical cost in softwash quotes. The chemical cost of a softwash job is not negligible. On a moss-heavy 80m² roof, chemical materials alone can cost £25–£60 at wholesale prices. If you have not built this into your per-square-metre rate, you are subsidising every softwash job from your labour margin. Calculate your chemical cost per litre of working solution, estimate the litres required for the job, and include it as a cost input before you set the price.
Not charging mobilisation on one-off jobs. Regular window round clients effectively amortise your travel cost across many visits. A one-off pressure wash or gutter clearance has no such amortisation — the travel, loading, and setup cost falls entirely on that single job. A mobilisation charge of £30–£75 makes one-off jobs economically viable and sets a clear boundary with clients who want a single visit at round rates.
Treating softwash as a variation of pressure washing. Softwash and pressure washing are not the same service at different pressures. They require different equipment, different risk management, different chemical knowledge, and different insurance cover in some cases. If you are offering softwash, price it as a distinct premium service — not as a low-pressure variant of your washing rate. The difference in chemical cost, dwell time, and environmental risk justifies a 30–60% rate premium.
Not including a minimum charge. A £45 gutter clearance job that takes 20 minutes of travel, 20 minutes of work, and 20 minutes to invoice and collect payment is not profitable at most hourly targets. Set a minimum job value (£80–£120 is industry standard for residential exterior cleaning in 2026) and hold it. Small one-off jobs below your minimum are better declined or referred to a local contact — they consume administration time disproportionate to the income.
Quoting without confirming the payment date. Payment terms on exterior cleaning are frequently ambiguous because they are never written down. A client who pays their window cleaner in cash on the day is a different financial relationship from a client who wants to pay via BACS "end of the month." Decide your payment terms, write them on the quote, and state them when you present the price. Slow payment is one of the biggest cash-flow problems for small exterior cleaning businesses in England, Scotland and Wales.

How to upsell on exterior cleaning quotes

An exterior cleaning visit is a high-opportunity moment for additional revenue. You are already on site, you have already assessed the property, and the client has already made a trust decision by letting you quote. Upsells from an exterior quote convert at far higher rates than cold offers, provided they are relevant and presented professionally.

Gutter clearance as a window cleaning add-on

This is the easiest upsell in the sector. If you are cleaning windows, you are at height and can see the gutters. A brief note — "I noticed your front gutters are holding debris, I can clear them for £[X] on this visit or schedule it for the autumn" — converts at 40–60% in our experience with UK window cleaning businesses. Annual gutter clearance added to a fortnightly window round adds £60–£90 per property per year at minimal incremental cost. At 30 properties, that is £1,800–£2,700 in additional annual revenue.

Fascia, soffit and bargeboard cleaning

Fascias and soffits discolour with algae and environmental grime on the same timescale as windows. If you are doing reach-and-wash window cleaning, you have the equipment to include fascia cleaning at marginal additional cost. Offer it as an annual or bi-annual add-on: a typical 3-bed semi in Leeds or Birmingham has approximately 30–40 linear metres of fascia and soffit — at £1.50–£2.50/m, that is £45–£100 as an add-on. Present it on the quote as a named optional line item with a tickbox to accept.

Driveway or patio while on site for softwash

A softwash client has already accepted the concept of chemical treatment for their property exterior. The step to pressure washing the driveway or patio is small. If you are bringing a pressure washer or can easily add one, offer it directly: "While we are treating the roof, we could also pressure wash the driveway — it would take an additional [1.5 hours] and add £[XX] to the job. Would that be useful?" Same mobilisation cost, significant additional revenue. Always present as an optional line item in the quote, clearly priced, so the client can accept or decline without awkwardness.

Recurring treatment programme

For softwash clients in particular, an annual or biannual maintenance programme dramatically extends the life of the treatment, prevents regrowth from becoming severe, and locks in guaranteed income for your business. A maintenance programme priced at 30–40% of the initial treatment cost (typically £60–£150/year for a residential roof) is high-value for the client and high-margin for you. Include it as a named option on every softwash quote: "Optional maintenance programme: one visit per year to inspect and re-treat any regrowth — £[XX]/year, invoiced in [month]."

ℹ Upsells work best when they are already on the quote

An upsell presented verbally at the end of a job feels like a sales pitch. The same upsell listed as a named optional line item on the quote before the job starts feels like a helpful service. Put your upsells on every quote as optional items, clearly priced. Clients who want them will tick them. Clients who don't won't feel pressured. Your conversion rate on optional quote items will be significantly higher than your conversion rate on verbal offers after the work is done.

Frequently asked questions

How much should I charge for window cleaning in the UK?

UK window cleaning prices in 2026 vary by property size, method and region. A typical 3-bed semi on a regular fortnightly round: London and South East £16–£22, Midlands and North £10–£16, Scotland and rural areas £8–£13. Reach-and-wash commands a 10–20% premium over traditional method. One-off cleans should be priced at 1.5–2× the round rate — there is no frequency income to average against the travel and setup cost.

What is the going rate for pressure washing per square metre in the UK?

UK pressure washing rates in 2026 range from £3–£8 per square metre depending on surface type. Block paving: £5–£8/m² (most labour-intensive). Concrete: £3–£5/m². Patios (Indian sandstone, porcelain): £4–£7/m². Rendered walls: £4–£6/m². Always add a mobilisation charge of £30–£75 on one-off jobs and set a minimum job value of £80–£120 to prevent uneconomic small visits.

Is softwash more expensive than pressure washing?

Yes — typically 30–60% more expensive for the same surface area. The premium reflects chemical cost (sodium hypochlorite, surfactants, growth inhibitors), dwell time that must be charged even though it is non-productive, rinsing, and environmental risk management. Softwash is the correct method for roofs, render, pebbledash and sensitive surfaces. Do not price it as a variation of pressure washing — it is a separate premium service.

How do I quote for roof cleaning in the UK?

UK roof cleaning is almost always softwash rather than pressure washing. Measure each roof pitch (length × width × pitch factor of 1.15–1.3). Standard 2026 rates: £8–£15/m² for residential roofs. Add MEWP or scaffolding if needed (quote as a separate line), an environmental risk premium (£50–£150) for bunding and plant protection, and a treatment guarantee covering the biocide's active period (12–24 months). Always require public liability insurance of at least £2 million for roof work.

What insurance do I need for exterior cleaning in the UK?

Exterior cleaning businesses in England, Scotland and Wales should carry: public liability insurance (minimum £1 million, £2 million recommended for roof work and chemical application), employer's liability (legally required if you employ anyone), tools and equipment cover (pressure washers and reach-and-wash systems: replacement value often £2,000–£8,000), and product liability insurance if applying biocidal chemicals. Some commercial clients — housing associations, local authorities, property managers — require £5 million public liability. Check your policy specifically covers working at height and chemical application.

Should I charge a mobilisation fee for exterior cleaning jobs?

Yes — always, on one-off jobs. Mobilisation covers loading equipment, travel, machine setup, water sourcing, and pack-down. A reasonable charge is £30–£75 for residential jobs and £75–£200 for commercial. Present it as a transparent named line item. Do not absorb it into your per-square-metre rate — it makes your rate look high on large jobs and makes small jobs uneconomic. Regular round clients amortise travel cost naturally; one-off clients do not.

How do I add gutter clearance as an upsell on a window cleaning round?

Gutter clearance is the highest-conversion upsell in window cleaning because you are already at height with access to the gutters. Price it at £2–£4/m of guttering (a 3-bed semi has approx 20–30m) or as a flat rate of £45–£90. Offer it as an annual autumn add-on to your round. Include it as an optional line item on every new-client quote — pre-quoted items convert at a significantly higher rate than verbal offers after the clean.
