The UK cleaning industry turns over roughly £24 billion a year. It employs around 700,000 people and is made up overwhelmingly of small businesses — sole traders, family operations, local companies with a handful of staff. The barrier to entry is genuinely low. The barrier to running a profitable cleaning business is considerably higher.
This guide is for people who are serious about starting a cleaning company — not just trying it on the side, but building something that earns real money and can grow. It covers every step: which type of cleaning to start, how to set yourself up legally, what insurance you actually need, how to price without losing money, and how to get your first clients without spending a fortune on advertising.
Step 1: Choose which type of cleaning business to start
The cleaning industry splits into three main categories, and which one you choose has a big impact on startup costs, equipment needs, how you find clients, and how the business scales. Most successful cleaning businesses eventually operate in more than one area — but starting focused gives you a much better chance of building a profitable base quickly.
Residential (domestic) cleaning
Cleaning people's homes on a regular basis — weekly, fortnightly, occasionally for deep cleans. Typically charged at an hourly rate (£14–£28/hr depending on region) or a fixed price per clean. This is the lowest-cost type to start: you can begin with just your own labour and basic supplies, then invest in better equipment as income grows.
Best for: Low startup budget. Predictable recurring revenue once you have a regular client base. Suits people who want to work independently and build a local reputation.
Exterior cleaning
Window cleaning, pressure washing, gutter clearing, soft washing, driveway and patio cleaning. Equipment costs are higher — a decent window cleaning water-fed pole system costs £500–£2,000; a professional pressure washer £300–£3,000. But individual job values are higher and route-based work (recurring window cleaning) is extremely scalable.
Best for: People willing to invest more upfront for higher job values. Combines well with residential cleaning to offer clients a full exterior service.
Commercial cleaning
Cleaning offices, retail premises, schools, healthcare facilities, hospitality venues. Contract values are higher — a small office contract might be worth £500–£2,000/month. But sales cycles are longer, compliance requirements are stricter (RAMS, COSHH documentation, sometimes DBS checks), and you typically need to be operating already before you can bid credibly for contracts.
Best for: People with some commercial experience or credibility, or those willing to start small and build a portfolio of client sites before bidding for larger contracts.
Step 2: Set yourself up legally
There is no licence required to clean in the UK. But there are legal requirements you must meet before you take on your first client.
Register as self-employed with HMRC
If you're starting as a sole trader (the simplest structure), you need to register with HMRC as self-employed. You must do this by 5 October in the second tax year of your business — but doing it immediately is sensible so you receive your Unique Taxpayer Reference (UTR) number and can set up your record-keeping from day one.
Registration is free and takes around 20 minutes at gov.uk/register-for-self-assessment. You'll then file a Self Assessment tax return each year and pay Income Tax and National Insurance on your profits.
Limited company — do you need one?
Most cleaning businesses start as sole traders, and there's no reason to immediately form a limited company. As your profits grow above roughly £30,000–£40,000/year, a limited company structure may become more tax-efficient. But it also comes with more admin: annual accounts, confirmation statements, corporation tax. Get advice from an accountant before making the switch.
Business bank account
Not a legal requirement, but strongly advisable. Mixing personal and business money makes record-keeping messy, complicates your tax return, and looks unprofessional to clients who pay by bank transfer. Many banks offer free business accounts for the first year. Get one before you invoice your first client.
Step 3: Get the right insurance
This is non-negotiable. You need insurance in place before you set foot in a client's property.
| Insurance type | Required? | Typical cost | Why you need it |
|---|---|---|---|
| Public liability | Essential | £100–£250/yr | Covers damage to client property or injury to a third party caused by your work |
| Employers' liability | Legal requirement if you have employees | £250–£500+/yr | Covers injury or illness claims from employees — £5m minimum legally required |
| Key holder insurance | Recommended if you hold keys | Often included with PL | Covers costs if client keys are lost or stolen |
| Tools & equipment cover | Advisable | £50–£150/yr | Covers loss or damage to your equipment — especially important for exterior cleaners |
| Van/vehicle insurance (business class) | Required if using vehicle for work | Varies | Social domestic & pleasure policies do NOT cover commercial use — you need Class 1 business use |
Step 4: Set your prices correctly from the start
The most common mistake new cleaning businesses make is pricing based on what they think the market will accept — usually by looking at what others charge and going slightly lower to win work. This is a race to the bottom that leaves you earning less than minimum wage once all your costs and unbillable time are accounted for.
Instead, start from what your business needs to be viable and work outward.
Calculate your minimum viable rate
Work out your annual costs (insurance, equipment, fuel, phone, software, HMRC payments on your own tax). Divide by the number of billable hours you realistically expect to work per year — not the hours you're working, but the hours you're actually charging clients for. For a solo operator working 5 days a week, that's more like 800–1,000 billable hours after accounting for admin time, driving, quoting and holidays.
Then factor in what you need to take home after tax. At the current basic rate, Income Tax plus Class 4 NI takes roughly 29–34% of your profits above the personal allowance. If you want £30,000/year in take-home pay, you need closer to £45,000 in profit.
Window cleaning round averages: £8–£20 per property per visit.
Commercial cleaning: £12–£18/hr (often with a minimum contract value).
If your calculation says you need £18/hr to run a viable business in a market where most people charge £16, charge £18. The clients who leave over £2/hr were not going to be good clients anyway.
Step 5: Get your first clients
You don't need a website, an advertising budget, or a big social media following to get your first ten clients. You need to tell people you exist and ask for referrals from the moment you start.
Tell everyone in your personal network
Send a message to everyone you know — not just a vague post, but a direct message. Tell them you've started a cleaning business, what you do, roughly what you charge, and ask if they or anyone they know might be interested. You will get clients from this.
Set up a Google Business Profile immediately
This is free and is the single most important online tool for a local cleaning business. A well-maintained Google Business Profile with genuine reviews will generate inbound enquiries from day one. Set it up, fill in every field, and ask your first clients to leave a review as soon as the job is done.
Post in local Facebook groups
Every area has a local community Facebook group. Introduce yourself and your business — what you offer, your area, a contact method. Don't spam, but a genuine introduction post in the right groups can generate several enquiries in the first week.
Leaflet drops in target streets
Old-fashioned but still effective for residential cleaning. Target streets where your ideal clients live — identified by property type, postcode data, or simply areas you want to work in. A simple, clean leaflet with a clear offer and easy contact method converts well.
Ask for a referral after every job
Referrals are the highest-converting source of new clients in cleaning. A happy client who tells three friends about you is worth more than any paid advert. Make it a habit: after every job, ask if they know anyone who might benefit from your service. Make this a non-negotiable part of how you operate.
Step 6: Set up your operations properly from day one
The biggest mistake growing cleaning businesses make is leaving their operations to grow organically — which usually means on spreadsheets, in their head, or across a chaotic mix of WhatsApp messages and handwritten notes. When you have 5 clients this is annoying but manageable. When you have 50, it becomes a serious business risk.
What you need to manage operationally
- Scheduling — who's cleaning what, when, and for how long
- Client records — contact details, access notes, preferences, frequencies
- Invoicing — sending invoices, tracking what's been paid, chasing late payments
- Income and expense records — required for your tax return, and from April 2026 for MTD ITSA if your income exceeds £50,000
- Staff management (when you hire) — rotas, pay, attendance, holiday
Step 7: Understand your tax obligations
Tax surprises are one of the most common reasons new cleaning businesses fail. If you don't understand what you owe — and save for it — you can find yourself with a tax bill you can't pay at the end of the year.
Self Assessment
As a sole trader, you pay Income Tax and National Insurance on your profits (income minus allowable business expenses) through Self Assessment each January. The deadline for the online return covering the 2025–26 tax year is 31 January 2027.
Allowable expenses
You can deduct legitimate business costs from your income before calculating tax. These include: cleaning materials and equipment, mileage at 45p per mile (first 10,000 miles), public liability insurance, business phone costs, software subscriptions, accountant fees, and work clothing (uniforms only — not general clothing). Keeping accurate records of all expenses is essential.
Making Tax Digital (MTD ITSA)
From April 2026, sole traders and landlords with qualifying income over £50,000 must keep digital records and submit quarterly updates to HMRC — replacing the annual Self Assessment for those above the threshold. The threshold drops to £30,000 from April 2027. If you're starting a cleaning business now, plan from day one to use MTD-compatible software.
Step 8: Plan for growth before you need to
The transition points in a cleaning business — from solo to first hire, from one team to two, from local to regional — each come with new challenges: payroll, employer obligations, route efficiency, quality control, client retention under delegation. Planning for these before you hit them avoids the reactive scramble that causes otherwise good businesses to stall.
The most resilient cleaning businesses are built around recurring revenue: clients who book regularly, pay reliably, and stay long-term. A residential cleaner who converts 70% of clients to fortnightly regulars has a completely different business model to one who does mostly one-off deep cleans. Build your client base deliberately around the type of work that gives you predictable income.
