Setting Up a Cleaning Business
A plain-English guide for one-person cleaning businesses — what you legally must do, what you should do, and why each step protects you.
1. Why bother getting legit
You can start cleaning for cash tomorrow with a mop and a smile. Plenty do. Here's why that's a mistake within your first few months, not your first few years.
The stakes, in order of how fast they bite:
- HMRC catches up eventually. Trading income over £1,000 in a tax year must be registered with HMRC — miss the deadline and penalties start at a percentage of the tax owed, rising the longer you delay. It's not a "might happen" — untaxed income with a paper trail (bank transfers, invoices, reviews naming your business) is exactly what gets flagged.
- No insurance means one bad day ends the business. Knock over a client's TV, trip their dog, stain a £3,000 carpet — without public liability cover, that bill is yours personally, not "the business's."
- Bigger jobs won't touch you without paperwork. Letting agents, offices, and anyone with a facilities manager will ask for proof of insurance and a DBS certificate before they'll even discuss a contract. No paperwork, no quote request.
- You can't get Southend Verified™ without it. The badge that gets you above the noise on this site — and the trust that wins the customer over a stranger — requires exactly the documents this guide walks you through: insurance, DBS, ID.
What "done properly" unlocks:
- Contracts you're currently invisible to (commercial, letting agents, corporate)
- The Southend Verified™ badge and the enquiries it brings
- A clean, provable income history — useful for mortgages, loans, maternity pay, and Universal Credit calculations
- One bad accident doesn't wipe out your savings
None of this takes long. Realistically: one afternoon for HMRC, one phone call for insurance, one form for DBS. The rest of this guide is that afternoon, broken into pieces.
2. Sole trader vs Ltd — pick one
Sole trader means you and the business are legally the same thing. No separate registration beyond telling HMRC you're trading. You keep all profit after tax. You're personally liable for debts — but that's what insurance is for (Section 4).
Limited company means the business is a separate legal entity. You're a director drawing salary and dividends from it. More paperwork, more cost, but some tax advantages once profit is high and consistent.
For a one-person cleaning round: start as a sole trader. Here's the maths that settles it.
What you keep at typical cleaner income:
- Personal allowance: £12,570 tax-free, then 20% income tax up to £50,270
- National Insurance (Class 4): 6% on profits between £12,570–£50,270
- No separate registration fee — HMRC sign-up is free (Section 3)
What a limited company costs before you earn a penny:
- £100 to incorporate with Companies House
- £50/year confirmation statement, every year, whether you traded or not
- An accountant most directors need — realistically £500–£1,500/year, because company accounts are a different job to a Self Assessment return
- Separate business bank account, formal payroll if you take a salary
The honest verdict: at typical solo cleaner turnover, a limited company adds cost and admin without meaningfully changing your tax bill. The tax advantage only shows up once you're consistently clearing somewhere around £40,000–£50,000 profit a year — and even then it's a few thousand pounds saved, not life-changing, and it comes with proper year-round bookkeeping.
Rule of thumb:
| Situation | Structure |
|---|---|
| Starting out, building a client base | Sole trader |
| Turning over under £40k profit | Sole trader |
| Consistently clearing £40k–£50k+ profit for two years running | Worth an accountant's opinion on Ltd |
You can switch to a limited company later — plenty do, once the business has genuinely outgrown sole trader status. You can't easily undo the £100 and the admin if you go Ltd from day one and don't need it.
3. Register with HMRC
This is the one everyone puts off. It's also the fastest — 10 to 15 minutes, free, done online.
What you're actually registering for: Self Assessment, not "a business." There's no company to set up. You're simply telling HMRC "I'm self-employed, expect a tax return from me."
Do you even need to? If your total self-employed income stays under £1,000 in a tax year (the trading allowance, based on turnover before expenses), you don't have to register at all. The moment you go over £1,000, you do — from that first pound over the line, not just the excess.
The deadline: 5 October. Specifically, 5 October following the end of the tax year you started trading. UK tax years run 6 April to 5 April. Example: start cleaning in November 2025 (2025/26 tax year) → register by 5 October 2026.
There's no reason to wait that long. Register the week you take your first paying client.
What you need before you start:
- National Insurance number
- Government Gateway ID (create one during sign-up if you don't have one)
- Full name, address, date of birth
- The date you started trading
- A one-line description of the work — "domestic cleaning" is fine
The steps:
- Go to gov.uk/register-for-self-assessment
- Choose "Sole trader" (not "Partner," not "Not self-employed")
- Fill in your details and trading start date
- Submit — you'll get an on-screen confirmation
- Wait for your Unique Taxpayer Reference (UTR) — arrives by post, allow up to 10 working days, sometimes longer
- Once you have both a UTR and Government Gateway login, you're set up to file your annual return
What happens if you miss 5 October: HMRC calls this "failure to notify," and the penalty scales with how much tax you owed and how late you were — it isn't a flat fine. The bigger practical risk is timing: without a UTR in hand, you can't file your return by the 31 January deadline that follows, and that miss is an automatic £100 fine the moment the clock strikes midnight, with more added the longer it runs. Register early and this entire risk disappears.
One more date to calendar now: 31 January every year — file your return and pay what's owed. Set a reminder. It arrives faster than it feels like it will.
4. Get insured
Insurance isn't legally required for a sole trader cleaner. But try getting a contract without it. Try keeping your savings after one accident without it.
Public liability insurance covers you when something goes wrong at a client's property — you knock over a lamp, trip a family member, stain a sofa. It pays the compensation and legal costs instead of you.
What it costs:
