How to Start a Cleaning Business in the UK

Starting a cleaning business has one big advantage over most trades: the barrier to entry is low and you can start earning within weeks rather than months. It has one big disadvantage, which is that almost anyone can do the same thing, so the businesses that survive are the ones that get the admin right early.

Here is the practical version.

What you actually need

Register as a sole trader. You can start immediately and tell HMRC once you are trading. Trading as a limited company makes sense later, usually once profits justify the extra admin.

Public liability insurance. This is not optional for domestic or commercial cleaning. Most commercial clients and letting agents will ask for a certificate before they let you through the door. Expect a modest annual premium for a small operation; get cover that matches the value of the properties you clean.

A DBS check. Not legally required for general cleaning, but a large share of domestic customers and virtually all letting agents will ask. Being able to say yes immediately wins you work.

An employer's liability policy the moment you hire anyone — it is a legal requirement, not a nice-to-have.

What it costs to run

Van or car, fuel, equipment, consumables, insurance, phone, and your software. Add it all up honestly before you set a price, because the most common mistake new cleaning businesses make is pricing against a competitor whose costs they cannot see.

The van running cost calculator will give you a per-day figure you can actually plan around, and the day rate calculator works backwards from what you want to take home — including an honest allowance for the days nobody books you.

How to price the work

Two models, and you should know which you are running:

• Hourly. Common for domestic and end-of-tenancy work. Work out the rate you need and hold it.
• Per job or per property. Common for commercial contracts. Estimate hours, add margin, then measure whether you were right — this is where most cleaning businesses quietly lose money.

The cleaning price calculator works out the hourly rate you need from your weekly costs and billable hours.

Whatever you choose, quote in writing. A verbal price is where disputes come from.

Getting your first customers

• Letting agents. End-of-tenancy cleans are repeatable, they come with a deadline, and agents need reliable people. Visit them in person.
• Local Facebook groups. Genuinely effective for domestic work. Answer questions properly before you ever mention your business.
• Google reviews from day one. Ask every single customer, on the day, while you are still standing there. The businesses that dominate local search are rarely the best cleaners — they are the ones with 60 reviews instead of 6. Start with the review link generator and the review request wording.
• Recurring over one-off. Four weekly cleans are worth far more than four one-off cleans, and they are the difference between a business and a series of jobs.

Where the admin stops scaling

The pattern is predictable. At five customers you keep it in your head. At fifteen you are using a paper diary and a spreadsheet. At forty you are spending your evenings invoicing, chasing money, reminding people about appointments, and asking for reviews you never get to.

That is the point where the admin becomes the reason you cannot take on more work. It is worth recognising early, because the fix is cheap at fifteen customers.

Cleaning businesses usually need three things to stop drowning: recurring schedules that generate their own reminders, invoices that chase themselves, and review requests that go out automatically. That is what FlowSync does — see how it works for cleaning companies or start a 14-day trial when you are ready.
