Exterior cleaning is one of the most accessible service businesses you can start in the UK. You do not enter clients' homes. You do not hold keys. Much of the work is visible from the street, which makes canvassing and word of mouth unusually effective. And the window cleaning round model — clean the same properties every four, six or eight weeks — creates the kind of predictable recurring income that most businesses spend years trying to build.
This guide covers all four core exterior cleaning services — window cleaning (water-fed pole), jet washing, soft washing and gutter clearing — with honest startup cost ranges, pricing benchmarks, legal requirements, and a practical route to building a profitable round in your first year.
Why exterior cleaning is one of the best service businesses to start
When people compare cleaning business models, exterior cleaning often wins on the metrics that matter most to new operators. Here is why.
You never go inside. Interior cleaning — domestic or commercial — involves accessing clients' homes or workplaces, key holding, alarm codes, and the liability that comes with being present around personal property. Exterior cleaning sidesteps all of this. You work on the outside of buildings, on driveways, patios and roofs. The trust threshold is lower, which makes customer acquisition faster.
Recurring revenue from day one. A window cleaning round is one of the few self-employed models where customers pay you on a fixed cycle whether or not they remember to book. Once someone joins your round, they expect you to show up every four or six weeks. Done-and-forgotten services like jet washing are good margin earners, but window cleaning is the engine that underpins everything else.
High add-on value. A customer who pays £12 to have their windows cleaned every four weeks is also a customer who needs their gutters cleared twice a year (£60–£80), their driveway jet washed in spring (£100–£150), and possibly their render or roof soft washed (£150–£300). Once you have access to a property on a recurring basis, cross-selling exterior services is straightforward — you can see exactly what needs doing.
Relatively low barriers to entry. A professional water-fed pole (WFP) window cleaning setup can be purchased for £430–£1,050. You do not need premises. A second-hand van and some signage, and you are operational. Compare this with interior commercial cleaning, which typically requires substantial liability coverage, staff, disclosure checks and contract tendering before you see your first pound.
Income potential. A solo exterior cleaner operating an efficient window cleaning round with gutter clearing and seasonal jet washing add-ons can realistically earn £30,000–£55,000 per year. A two-van operation with a reliable employee can reach £80,000–£120,000 in turnover. Multi-van exterior cleaning businesses with four or more vehicles regularly turn over £150,000–£200,000+. The model scales because the recurring round can be sold — exterior cleaning rounds have a secondary market, with established rounds trading for six to twelve times their monthly value.
The main drawback: weather. Exterior cleaning is outdoor work, and British weather is unpredictable. Expect to lose 15–20% of your working days each year to rain, frost, or wind strong enough to make ladder and WFP work unsafe or produce poor results. The solution is to build a schedule buffer, maintain a cancellation list you can fill quickly, and use indoor down-time for admin, quoting, and canvassing. Do not model your income on 250 working days per year — model it on 200–210.
The exterior cleaning services and which to start with
Exterior cleaning is not a single service — it is a cluster of related services that share equipment, customer base, and the same outdoor working environment. Understanding each service helps you decide where to start and how to layer services over time.
Window cleaning (water-fed pole)
WFP window cleaning uses a carbon fibre or fibreglass pole — extended from ground level — connected to a pure water supply. The pure water (produced by a reverse osmosis or deionised filtration system) cleans glass without leaving mineral deposits, meaning windows dry spot-free without wiping. WFP eliminates most ladder use, meaning faster cleans, lower fatigue, and significantly reduced Work at Height risk. It is the best entry point for an exterior cleaning business: recurring revenue, low equipment cost, and a proven canvassing model. Most new exterior cleaners in 2026 should default to WFP — traditional ladder-and-squeegee is slower and harder to scale.
Jet washing (pressure washing)
Jet washing — driveways, patios, block paving, decking, render, paths — is one of the most in-demand exterior services in the UK. It is not recurring in the same way as window cleaning (most customers jet wash once or twice a year at most), but it commands strong per-job pricing and is an easy cross-sell to an existing window cleaning round. Use a petrol pressure washer for professional work — electric domestic-grade machines are too slow and insufficiently powerful for commercial output.
Soft washing
Soft washing uses low-pressure pumps and biodegradable surfactant-based chemicals to clean surfaces that cannot withstand the pressure of a jet washer — roofs, render, fascias, conservatory panels, algae-covered fencing. It is a growing market as more property owners become aware that pressure washing a render facade or clay-tiled roof causes long-term surface damage. Soft washing requires chemical handling competency and COSHH compliance — see the soft wash safety guide for a full breakdown. It commands the highest margins per job of any exterior cleaning service.
Gutter clearing
Gutter clearing is high-demand, seasonal (peak in autumn and spring), and straightforward to add to any window cleaning round. Vacuum-based gutter clearing systems allow ground-level operation, eliminating ladder risk entirely. Demand is consistent across all property types — blocked gutters cause damp, and most homeowners know it. It is the easiest add-on service to sell to an existing window cleaning customer base.
Other services: conservatory roofs, solar panels
Conservatory roof cleaning uses WFP equipment you likely already have from window cleaning — it is an easy extension. Solar panel cleaning is a growing market as panel installations increase across UK domestic and commercial properties; dirty panels lose 15–25% of generation efficiency, giving customers a compelling reason to have them cleaned annually. Neither service requires major additional equipment investment if you already operate a WFP window cleaning round.
Recommendation for new starters: Launch with window cleaning (WFP) and gutter clearing as your two core services. They share a customer base, are both recurring or high-frequency, and your combined startup equipment cost is under £2,000. Add jet washing in your second or third month once the round is generating reliable income. Add soft washing when you have consistent enquiries and are ready to invest in chemical handling training and COSHH documentation.
Equipment and startup costs by service
The tables below give honest current-market cost ranges for each service's equipment. Prices are for new equipment — buying second-hand (Facebook Marketplace, specialist forums like the Window Cleaning Forums) can reduce costs by 30–50% on most items. The "can you hire first?" column reflects whether hiring before buying is practical.
| Service | Equipment needed | Typical cost | Hire/borrow first? |
|---|---|---|---|
| Window cleaning (WFP) | WFP pole (carbon fibre entry) · backpack pure water system · RO/DI filter · squeegee kit for traditional | Pole £80–£300 · Backpack £200–£500 · Filter £100–£250 · Squeegee kit £50 Total: £430–£1,050 |
Not practical — own equipment needed from day one |
| Jet washing | Petrol pressure washer · range of nozzles and lances · rotary surface cleaner | Washer £200–£500 · Lances/nozzles £50 · Surface cleaner £80 Total: £330–£630 |
Yes — hire for first 3–4 jobs to test demand before buying |
| Soft washing | Low-pressure pump and tank system · chemical containers and mixing · PPE (chemical-grade) | Pump/tank £300–£800 · Containers £50 · PPE £80 Total: £430–£930 |
Not recommended — requires familiarity with your own system |
| Gutter clearing | Gutter vacuum system (ground-level) or pole and bucket kit with ladder | Vacuum system £300–£900 · Pole kit £150–£400 Total: £150–£900 |
Pole kit — yes. Vacuum system — yes, if a trial day hire is available |
| Van | Essential — second-hand diesel panel van (Transit, Sprinter, Vivaro). Signage and/or wrap. | Van £4,000–£9,000 · Signs/wrap £200–£600 Total: £4,200–£9,600 |
No — a van is not optional for an exterior cleaning business |
A realistic all-in startup budget for window cleaning and gutter clearing, with a decent second-hand van, is £5,500–£11,000. If you already own a suitable vehicle, or can start by renting one short-term, the equipment-only cost drops to £1,000–£2,000 for these two services. Many successful exterior cleaners start with a small personal loan or by reinvesting savings — there is no need for commercial finance to get started.
Legal and admin setup
The admin side of starting an exterior cleaning business is simpler than many people expect. Here is what you actually need to do, in rough order.
Register as self-employed with HMRC
If you are starting as a sole trader — the right structure for almost all new exterior cleaners — register with HMRC for Self Assessment as soon as you start trading. You can register online at gov.uk. You will pay Income Tax on your profits and Class 4 National Insurance, plus Class 2 NIC. Keep records of all income and expenses from day one — van fuel, equipment, insurance, chemicals, phone, and any business mileage are all allowable expenses.
Business bank account
Open a separate business bank account before you take your first payment. Mixing business and personal finances creates accounting problems and makes Self Assessment harder than it needs to be. Several UK banks offer free or low-cost accounts for sole traders — Starling, Monzo Business and Tide all work well for small exterior cleaning businesses.
Public liability insurance
Public liability insurance is non-negotiable. You are working on or near people's property — a pressure washer cracking a window, a gutter clearance dislodging a ridge tile, or a WFP pole breaking a conservatory panel are all realistic scenarios. Minimum cover is £2m; take out £5m if you intend to quote for any commercial work, as most commercial clients require it. Annual premiums for a sole trader exterior cleaner typically run £150–£350 per year. Specialist cleaning insurance providers (Premierline, Hiscox, Simply Business) offer competitive rates.
Employer's liability insurance
If you hire anyone — an employee, a labour-only subcontractor, or even a family member being paid to help — you need employer's liability insurance of at least £5m. This is a legal requirement, not optional. Fines for operating without it start at £2,500 per day.
COSHH assessments for soft washing
If you use any chemicals — soft wash surfactants, algaecides, biocides — you are legally required to complete COSHH assessments for each substance under the Control of Substances Hazardous to Health Regulations 2002. See the soft wash safety guide for worked examples and what your assessments must cover.
VAT registration — watch the threshold
You must register for VAT once your rolling 12-month turnover exceeds £90,000. The exterior cleaning round model can approach this threshold faster than it feels — see the VAT watch section below. Registering voluntarily below the threshold can make sense if most of your customers are VAT-registered businesses (they can reclaim the VAT), but most domestic exterior cleaners should wait until they approach the threshold before registering.
Pricing exterior cleaning services
Exterior cleaning pricing varies significantly by region, property type, and service. The ranges below reflect current UK market rates — rural operators in the south-east and London commuter belt can price at the top of these ranges; operators in lower-cost regions or in areas with more competition may price closer to the bottom.
Window cleaning (per property, not per hour)
Window cleaning is priced per property, not per hour. Pricing by the hour incentivises slow work and makes it impossible to plan your day. Common benchmarks:
- 2-bed house: £8–£12 per clean
- 3-bed semi-detached: £10–£15 per clean
- 4-bed detached: £15–£25 per clean
- Conservatory add-on: £4–£10 extra per clean
On a well-built round, an efficient WFP operator should be able to clean 15–25 residential properties per day, yielding £150–£375 in daily revenue before expenses. Urban density makes this possible; rural rounds with long travel times between properties will produce lower daily outputs even at higher per-property prices.
Jet washing
- Driveway (average semi-detached): £80–£180
- Patio or decking: £100–£200 depending on size and surface
- Block paving (large detached): £150–£250
- Commercial car parks or forecourts: quote on area — typically £0.50–£1.50 per square metre
Soft washing
- Render facade (average semi-detached): from £150
- Roof soft wash (average semi-detached): from £200
- Fascias, soffits and bargeboards: £80–£150 depending on property size
- Conservatory exterior including roof: £100–£200
Gutter clearing
- Terraced or small semi-detached: £60–£80
- Semi-detached (standard): £60–£80
- Detached: £80–£120
- 3-storey or larger detached: £120–£180
For all services: add a 25–50% premium for first-time cleans that are heavily soiled or have been neglected for multiple seasons. A first-time window clean takes two to three times as long as a maintenance clean. A first-time gutter clear on a house where gutters have not been touched in five years involves removing years of compacted debris. Price the work you are actually doing, not the work you hope it will be.
Never price a job without seeing it. This applies especially to jet washing, soft washing and gutter clearing. A photograph helps, but nothing replaces a site visit for jobs above £100. Mispriced jobs erode your margin and create customer service problems.
Building the recurring round
The recurring round is the defining feature of a successful exterior cleaning business. Here is how to think about building one deliberately rather than accumulating customers ad hoc.
Window cleaning is the backbone. A window cleaning round provides the regular rhythm that makes everything else possible — both operationally (you are in a neighbourhood every few weeks) and financially (you have a predictable income base). See the window cleaning round guide for a complete treatment of how to build, price and manage a round from zero.
Route efficiency: fill streets, not postcodes. New exterior cleaners often focus on postcode areas — "I want to work in SW19" — when they should be thinking street by street. The goal is to have multiple customers on the same street, or at minimum adjacent streets, so that travel time between jobs is minimal. One customer at each end of a postcode with three miles between them is less efficient than six customers on the same cul-de-sac. When you canvass, target streets where you can see existing customers' properties — and explain that you already clean on that street.
Add gutter clearing to the round in autumn and spring. Contact all your window cleaning customers in September and March with a gutter clearing offer. Frame it simply: you are already in the area on your regular round, and you can combine both services in one visit. Many will say yes — the convenience argument is strong.
Cross-sell jet washing in spring. April and May are the best months to sell driveway and patio jet washing to an existing window cleaning customer base. Driveways look their worst after winter; customers are thinking about garden preparation. A simple message — text or card through the door — offering a spring jet wash to your existing round customers will convert at a meaningful rate.
The compound effect of a mature round. Consider a window cleaner with 200 regular customers at an average of £12 per clean on a six-weekly cycle. That is approximately £25,000 in annual window cleaning revenue. Now add:
- 30% of customers taking an annual gutter clear at an average of £75 = 60 clears × £75 = £4,500
- 15% taking a spring jet wash at an average of £130 = 30 jobs × £130 = £3,900
- 5% taking a soft wash or render clean at an average of £180 = 10 jobs × £180 = £1,800
That is £10,200 in add-on revenue — a 41% uplift on the window cleaning base — without adding a single new customer to the round. As the round grows, this compound effect scales proportionally. It is the strongest argument for treating exterior cleaning as a round business rather than a job-by-job trade.
Safety and compliance for exterior work
Exterior cleaning involves working at height and handling chemicals. Both areas are regulated, and understanding the requirements will protect you legally and keep your insurance valid.
Work at Height Regulations 2005
The Work at Height Regulations 2005 require anyone who works at height — meaning any height where a fall could cause injury — to assess and manage that risk. Key requirements:
- A risk assessment is required before using a ladder, working on a roof, or using elevated access equipment
- Ladders must only be used where a safer alternative is not practicable
- WFP window cleaning from ground level eliminates most ladder use for residential window cleaning — this is one of its key compliance advantages
- Gutter clearing with a vacuum system from ground level is similarly lower-risk than a ladder-based approach
- Soft wash roof work typically requires a risk assessment even if chemicals are applied at ground level — accessing the roof to inspect it beforehand may involve height risk
COSHH for soft wash chemicals
Soft wash chemicals — biocidal surfactants, sodium hypochlorite solutions, algaecides — require COSHH assessments before use. See the soft wash safety guide for full details on what assessments must cover and how to complete them.
Asbestos awareness
Before working on any building constructed before 2000 — especially pre-1980 properties — be aware that asbestos-containing materials (ACMs) may be present in roofing sheets, fascias, soffits, garage roofs, and textured coatings. You are not required to test for asbestos as an exterior cleaner, but you should have completed asbestos awareness training (widely available online, typically £20–£40) so you know what to look for and what to do if you suspect ACMs are present. Do not pressure wash or soft wash surfaces you suspect contain asbestos.
Public liability insurance must cover height work
Check your public liability policy explicitly covers working at height and external works. Some budget policies exclude height work above a specific level. If you intend to carry out any work above first-floor height — gutter clearing on larger properties, roof soft washing, chimney or fascia work — confirm coverage before you price or accept the job.
The VAT threshold trap for exterior cleaners
The exterior cleaning round model has a particular relationship with the VAT threshold that catches many operators off guard.
The UK VAT registration threshold is £90,000 in rolling 12-month turnover. Once you cross it, you must register and charge VAT on your services — a 20% addition to your prices that most domestic customers are not expecting and do not want to pay.
The round model scales silently. A window cleaner who adds a new customer every week, who cross-sells gutter clearing and jet washing as the round grows, and who raises prices annually can approach £90,000 without any single decision or moment that felt like crossing a threshold. You are not taking on a new contract or opening a new location — you are just cleaning more windows and more driveways, steadily, week after week.
The practical steps are: track income meticulously from day one, calculate your rolling 12-month total at the end of each month, and begin planning for VAT registration when you approach £75,000 rolling turnover — not £90,000. You need time to adjust your pricing, notify customers, and set up VAT accounting before the threshold is crossed. Being caught crossing the threshold without registering results in back-dated VAT liability paid from money you no longer have.
Getting your first exterior cleaning customers
Exterior cleaning has one significant customer acquisition advantage over most service businesses: the work is visible from the street, and you can quote on the spot.
Canvassing
Direct canvassing — knocking on doors in target streets — is more effective for exterior cleaning than for almost any other service business. You can see the property from the pavement. You can identify dirty windows, green driveways, blocked gutters, and algae-covered render before you ring the doorbell. You can demonstrate your credentials, explain your service clearly, and often start the same week. Conversion rates of 10–20% on a well-targeted canvassing round are common for new exterior cleaners.
Target streets where properties show visible need: driveways with green algae, windows visibly grimy from the street, gutters with plants growing from them. These are not just sales leads — they are properties where the customer already knows they need the service. You are shortening the decision.
Leaflet drops
Leaflets are less efficient than direct canvassing but can saturate an area faster. A well-designed A5 leaflet dropped across 200 houses in a target area will typically generate 3–8 enquiries. Repeat drops in the same area improve results — the third drop on the same street often outperforms the first. Include a specific offer ("Free first clean with a 3-month standing order") to improve response rates.
Local Facebook groups
Local community Facebook groups — "Residents of [Town]", "What's On in [Area]" — are active forums for service business recommendations. Join your target area's groups, introduce yourself when appropriate, and respond quickly to any posts asking for window cleaning or exterior cleaning recommendations. Reviews and referrals in these groups carry significant weight. One satisfied customer posting a recommendation can generate five to ten enquiries.
Google Business Profile
Set up a Google Business Profile from day one. It is free, it appears in local search results, and it is the single most important digital marketing channel for a local exterior cleaning business. Optimise your profile with: a complete description including all services, your service area, your pricing (ranges are fine), photos of completed work, and a request for reviews from every satisfied customer. A profile with 20+ positive reviews will appear above most local competitors in map results.
In rural areas, a well-maintained Google Business Profile can generate the majority of new business enquiries within 6–12 months of setup. In urban areas with more competition, it remains essential but may need to be combined with canvassing and leaflet work to generate critical mass in the early months.
