How to Start and Manage a Commercial Cleaning Business in the UK

Commercial cleaning has a low barrier to entry and a high barrier to doing it well. You can start with a van, some equipment and one contract. Growing past a handful of contracts takes contracts priced properly, reliable staff, legal compliance and systems that let you prove the work was done.

This guide walks through both stages: setting up, then running the business as it grows.

1. Decide what kind of cleaning company you are

"Commercial cleaning" covers very different businesses. Decide early which you are, because it shapes pricing, staffing and the clients you approach:

• Contract office cleaning. Recurring daily or weekly cleans, usually early morning or evening.
• Education. Schools and nurseries, with term-time rotas and holiday deep cleans.
• Healthcare and care. Higher standards, formal audits and infection prevention.
• Retail, hospitality and leisure. Often out of hours, with high footfall and visible standards.
• Specialist work. Deep cleans, builders' cleans, window cleaning or floor care.

Most successful small operators start narrow. Being "the company that cleans GP surgeries in our area" is easier to sell than "we clean anything".

2. Set up the business properly

Legal structure

You'll usually choose between operating as a sole trader or a limited company. A limited company separates your personal and business finances and is often expected by larger commercial clients. GOV.UK explains how to set up a limited company, or you can register for Self Assessment as a sole trader. An accountant can advise which suits you.

Register as an employer

If you'll employ cleaners, you must register as an employer with HMRC and run PAYE payroll. Plan this before your first hire, not after.

Insurance

• Employers' liability insurance is a legal requirement for most employers (GOV.UK).
• Public liability insurance isn't legally required, but almost every commercial client will ask for it, often with a minimum level of cover written into the contract.

Data protection

You will hold personal data about staff and client contacts. Most organisations that process personal data must pay the ICO data protection fee unless exempt.

VAT

You must register for VAT once your taxable turnover passes the threshold in a rolling 12-month period. The threshold has been £90,000 since April 2024 (GOV.UK). Many commercial clients are VAT-registered and can reclaim VAT, so some cleaning companies register voluntarily. Take advice.

3. Price contracts from the labour up

The most common reason cleaning companies struggle is underpriced contracts. Build every quote from the bottom up:

1. Measure the work. Walk the site, list areas and tasks, and estimate how long each takes at the required frequency.
2. Convert to labour hours per week, including periodic tasks spread across the year.
3. Cost the labour at the rate you'll actually pay. Include holiday pay, employer's National Insurance and pension contributions, and cover for sickness and leave.
4. Add direct costs: consumables, equipment, travel and supervision time.
5. Add overheads and margin.

Check current National Minimum Wage and National Living Wage rates on GOV.UK. They usually change each April, so build that into multi-year contracts.

4. Hire and keep good cleaners

Your reputation is made by the people on site at 6am. A few things matter enormously:

• Right-to-work checks before anyone starts (GOV.UK). This is a legal duty with significant penalties.
• A written statement of employment particulars from day one.
• DBS checks where the client or setting requires them, such as many schools and care settings.
• Induction at each site, not just a generic induction. Cover cleaners need it too.
• Auto-enrolment into a workplace pension for eligible staff (The Pensions Regulator).

Retention is a profit lever. Every leaver costs you recruitment time, induction time and often a dip in quality that a client notices. Stable, predictable shifts and being paid correctly and on time are the basics that keep people.

5. Health and safety

Cleaning involves chemicals, lone working, manual handling and working at height. At a minimum:

• Carry out COSHH assessments for the products you use and train staff on them (HSE).
• Write risk assessments per site, including lone working where it applies.
• Keep training records and accident and incident records.

6. Build the systems before you need them

This is the step most new cleaning companies skip, and the one that limits growth. Commercial clients will eventually ask:

• Did your cleaner turn up on Tuesday?
• Can you show me the toilets were done to specification?
• Who is covering while our regular cleaner is on holiday?

If the answers live in your head and your phone, you can't delegate, and you can't scale. Put these in place early:

1. One rota for every site, with named cover. See our guide on creating an effective cleaning staff rota.
2. Verified attendance, not phone-in or paper. Read best practices for tracking cleaning staff attendance.
3. Site checklists that mirror each contract specification.
4. A cover process for missed shifts. See how to reduce missed cleaning shifts.
5. Regular client reporting, even a simple monthly summary to start.

Dedicated cleaning management software brings these together. Whether you use software or not, decide the process first.

7. Manage the business as it grows

Somewhere between three and ten contracts, the owner usually stops being able to see everything personally. That's the moment to:

• Appoint supervisors with clear responsibility for a group of sites.
• Track a small set of numbers weekly: shifts started on time, checklist completion, issues open, and contracted against actual hours.
• Review profitability by site. A contract that regularly takes more hours than it was priced for needs a conversation at renewal.

We cover this stage in detail in how to manage cleaning staff across multiple locations.

A simple starting checklist

WhiteIQ is software built for the operational side of this list: rotas, attendance, evidence, compliance reminders and client reporting. If you're setting up those systems, you can explore WhiteIQ on its main website.
