How To Prepare Your Cleaning Business For A Client Audit

Client audits are increasingly common in commercial cleaning contracts, particularly for larger clients in healthcare, education, retail and facilities management. Some are scheduled annually; others happen with little to no warning. Either way, being prepared is far less stressful — and far more effective — than scrambling to pull documents together after the request comes in.

What auditors typically ask for

• Risk assessments for the site being audited
• COSHH assessments and Safety Data Sheets for chemicals in use
• Public and employers' liability insurance certificates
• Staff training records, including COSHH and manual handling
• Method statements for any specialist work carried out
• Evidence of DBS checks, where relevant to the site
• Incident and accident records, if applicable

The most common reason audits go badly

In our experience, it's rarely that the documents don't exist — it's that they can't be found quickly, are out of date, or are inconsistent across sites and staff. An auditor asking for a COSHH assessment and waiting twenty minutes while someone searches through email attachments creates exactly the impression you don't want, even if the document itself is fine.

Before the audit: get organised

Build a central compliance file — physical or digital — covering every site, with each document dated and easy to locate. Our guide on the 10 documents every cleaning company should have is a good starting checklist if you're building this from scratch.

Review dates matter as much as the documents themselves

An auditor checking a risk assessment or COSHH assessment will usually look at the review date first. A document that hasn't been reviewed in over a year, regardless of its content, often raises more concern than a minor gap in an up-to-date one. Make sure your risk assessments and COSHH files are reviewed on a clear, trackable schedule.

Training records: the detail that gets missed

Auditors increasingly ask not just whether staff were trained, but when, and whether it's been refreshed. This is where many cleaning companies fall down — the training happened, but there's no accessible record. See our guide on managing staff training records for a system that holds up under scrutiny.

After the audit

Treat any findings as a checklist for improvement, not just a box-ticking exercise. Clients notice which suppliers close out audit findings quickly and which ones let them linger — it's often a factor in contract renewal decisions.
