How to Choose a Commercial Cleaning Company — A Practical Guide for Businesses

Choosing a commercial cleaning company is not just a procurement decision — it's a trust decision. Your cleaning team will have access to your premises, often outside business hours, and the standard of their work will be visible to every employee and visitor every single day.

Here's a practical guide to help you choose the right commercial cleaning company for your business.

1. Check Professional Memberships

The most reliable indicator of a serious commercial cleaning company is membership of the British Institute of Cleaning Science (BICSc) — the UK's leading professional body for the cleaning industry. BICSc members are committed to recognised training standards, professional development, and best practice in cleaning methods and health and safety.

Ask any prospective cleaning company whether they are BICSc members. If they're not, ask why.

2. Verify Staff Vetting Procedures

All cleaning staff should be DBS (Disclosure and Barring Service) checked before being placed on any client site. This is non-negotiable for schools, medical practices, and any premises where staff work unsupervised.

Ask specifically: are all staff DBS checked, or just supervisors? Are reference checks carried out? What is the process for new starters?

3. Understand the Contract Structure

Avoid companies that require long-term contracts with penalty clauses for early termination. A subscription-based model — where you pay monthly and can cancel with reasonable notice — is far better for your business. It keeps the cleaning company accountable every single month.

Always read the small print: look for price review clauses, consumables charges, and scope-of-service definitions.

4. Ask About Cover Arrangements

What happens when a cleaner is sick or on holiday? A professional cleaning company will have cover teams available so your premises are never left uncleaned. Ask specifically how absences are managed and how quickly cover is arranged.

5. Request References from Similar Premises

Ask for references from businesses similar to yours — same sector, similar size, similar location. A cleaning company that cleans offices well may not have the specialist knowledge for medical premises or schools. Sector-specific experience matters.

6. Assess Responsiveness

How quickly does the company respond to your initial enquiry? How long does it take to get a quote? The speed and quality of their pre-sales communication is a reliable indicator of how they will manage your account once you're a client.

7. Check Insurance

Any commercial cleaning company should carry full public liability insurance and employer's liability insurance. Ask for certificates before signing any agreement.
