You do not need a licence to clean offices, but you do need to follow COSHH rules for chemicals and register as an employer before your first hire. Some clients will also ask for DBS checks on every cleaner.

Offices, surgeries, schools and shops all want different things. Pick one to start.

Light paperwork to start. More once you hire.

Contracts are the business. Price them so they still pay when wages go up.

Good cleaners are the business. Keeping them is cheaper than replacing them.

Steady work, careful pricing, no single client too big.

Why Spotless never lets one client be more than 20% of revenue

Spotless cleans 64 offices and community buildings in Dublin, and no client is allowed to be more than a fifth of revenue. That rule, plus contracts priced per square metre with an inflation uplift, has kept it growing 16% a year.

Questions people ask

Do you need a licence to start a cleaning business in the UK?

No. You need to register with HMRC, follow COSHH rules for chemicals and register as an employer before you hire. Most clients will also ask for public liability insurance.

How much should I charge for office cleaning?

Work out what one cleaner hour really costs you (wages, holiday pay, National Insurance, travel and supplies), add your overheads and profit, and never quote below that. Build a yearly price review into every contract.

Do my cleaners need DBS checks?

It’s not required by law for most office cleaning, but many clients ask for it. Schools and health settings almost always do.
