Choosing a commercial cleaning company is a bigger decision than it first appears. Get it right and you have one less operational headache, a healthier workplace, and a supplier you can trust. Get it wrong and you face inconsistent standards, high staff turnover, and the hassle of switching mid-contract.

If you're evaluating commercial cleaning companies in Exeter and Devon, here's what to look for — and what to avoid.

1. Check Accreditations First

Accreditations aren't just badges. They signal that a company has been independently assessed against recognised safety and quality standards. For commercial cleaning, the most relevant are:

If a company can't demonstrate current accreditations, that's a concern — especially for regulated environments like schools, medical practices, and construction sites. Always ask to see the certificate, not just the logo on their website.

2. Ask About Staff Consistency

One of the most common complaints about commercial cleaning companies is that the faces keep changing. A different operative every week means retraining, inconsistency, and security concerns if your site has restricted access.

Ask any prospective company whether they assign dedicated teams to individual sites — and what their staff retention looks like. Companies that invest in their people deliver better results and fewer management headaches for clients.

3. Look for Documented Processes, Not Promises

Any company can tell you their standards are high. Fewer can show you. The best commercial cleaning companies in Exeter will have documented cleaning playbooks for each environment, regular quality audits, and reporting that they share directly with you.

Ask to see a sample audit report before you sign anything. If they don't have one, that tells you everything you need to know.

4. Consider Your Specific Sector Requirements

A cleaning company experienced in offices may not have the protocols required for a dental surgery or school. Check whether the company has relevant sector experience and ask for references from similar environments. Common sectors across Exeter include:

5. Understand What's Included — and What Isn't

A low headline price can mask a limited scope. Before comparing quotes, make sure you're comparing like for like. Clarify whether the quote covers:

Absence cover — what happens when a regular cleaner is off sick?

If your space needs an intensive clean before a routine contract begins, ask whether the company offers a standalone commercial deep clean in Exeter as a starting point. This resets the baseline so ongoing maintenance stays manageable.

6. Red Flags to Watch Out For

Walk away from any company that shows the following signs:

7. Ask the Right Questions in the Meeting
