How to Start a Cleaning Business in the UK — Complete Guide 2026

Starting a cleaning business in the UK in 2026 is one of the lowest-cost, fastest ways to become your own boss. You don't need a licence, you can begin with customers using kit you probably already own, and there is consistent demand for both domestic and commercial cleaning. But the difference between a side job and a proper business is paperwork — and that's where most new cleaners trip up.

This guide walks you through everything you need to start a cleaning business the right way: setting your rates, sorting your legal registration, getting insured, and — most importantly — getting your contracts in place before your first paid job, not after something goes wrong.

Step 1 — Decide your market and pick a niche

Generic "I clean houses" struggles. Pick a clear niche and price accordingly: domestic cleaning, end-of-tenancy cleans, commercial cleaning, or a specialist like oven / carpet / window cleaning. Residential regulars give steady weekly income; end-of-tenancy jobs pay more per hour but are one-off. Most cleaners do best starting with domestic regulars for cashflow, then adding higher-value one-offs alongside.

Step 2 — Register with HMRC as a sole trader

You don't need to set up a limited company to start — most cleaners run as self-employed sole traders. Register for Self Assessment with HMRC (online, free), and you'll submit a self-assessment tax return each year. Register as soon as you can: HMRC's three-month rule starts from your "trading date", so doing it before or just after you start keeps you compliant. You only need to think about registering for VAT once your turnover passes the 2026 threshold of £90,000 per year.

Step 3 — Get insured before you take a job

Public liability insurance is a non-negotiable for professional cleaners. If you knock something valuable over or a client's pet is involved, you're personally liable without it. Policies are cheap — often a few pounds a month for £1m or £2m cover. If you hire anyone (even casually), check whether you need employer's liability insurance too (legally required once you have employees). Some commercial clients and agents will ask for your certificate before they'll work with you, so get it early.

Step 4 — Set your rates and how you'll get paid

UK rates for domestic cleaning typically sit between £14 and £25 an hour depending on your area and specialism; end-of-tenancy jobs often work out higher. Work out your minimum — the number that covers your time, travel, supplies, insurance and tax. Then decide how people pay: bank transfer is neatest for record-keeping, and taking a small block of visits in advance protects your diary. An invoice template and a written rate pinned to a contract stop you undercharging and give you something to point to at review time.

Step 5 — Sort your contracts before the first job

This is the step most new cleaners skip — and the one that costs them. Before you clean for anyone, agree in writing: the scope of work, your rate and payment terms, a cancellation policy, and a key holding agreement if you hold a client's key. A one-page service agreement turns "I thought you'd clean the oven" and "you didn't come on Thursday" into things you both agreed on in advance. It also gives you leverage on late cancellations and non-payment.

🔑 Hold keys? Protect yourself. If you carry a client's key, you need a signed key holding agreement before you take it. It's the single most important document a cleaner can have.

Step 6 — Get found: local SEO and referrals

Cleaning is a local business. Set up a simple Google Business Profile, ask happy customers for reviews, and get a one-page website. Neighbourhood Facebook groups and word-of-mouth bring in steady leads, but conversions improve dramatically when your prices and what's included are written down. If you're going to market online, a clean, honest site beats expensive ads — and the tools to build one are cheap in 2026.

Your 2026 paperwork checklist

• Register for Self Assessment (HMRC) — free, online
• Public liability insurance (and employer's liability if you hire)
• A signed service agreement for every client
• Key holding agreement — before you accept a key
• Cancellation policy with a clear notice period
• Invoice template and simple income/expense records
• GDPR note covering the client data you hold

The fastest way to get six of the seven items above done before your first job is to use a ready-made, UK-specific template pack rather than drafting them yourself and hoping they're right.
