Kitchen Extract Cleaning Certificate: What It Is and Why Every Commercial Kitchen Needs One

After a professional commercial kitchen extract clean, you should receive a post-clean report or certificate. Many kitchen operators file this away — or in some cases, don't receive one at all — without fully understanding what it represents and why it is potentially the most important piece of paper in their kitchen compliance folder.

What Is a Kitchen Extract Cleaning Certificate?

A kitchen extract cleaning certificate (sometimes called a post-clean report or TR19 certificate) is the formal documentation that a professional contractor produces after completing a commercial kitchen extract system clean.

At minimum, a compliant post-clean certificate should include:

Date and location — when and where the clean was carried out.

Scope of work — precisely what was cleaned: the canopy and hood, grease filters (cleaned or replaced), duct sections accessed and cleaned, fan and motor housing. A certificate that only says "canopy cleaned" without referencing the ductwork is not a complete clean record.

Pre-clean condition — some contractors include observations about the system condition before cleaning, including grease depth readings or photographs.

Post-clean condition — confirmation that the system has been cleaned to the required standard.

Cleaning methods and products — what was used to carry out the clean.

Next recommended service date — the contractor's recommendation for when the next clean is due, based on their assessment of the kitchen's use intensity.

Contractor details — the cleaning company's name, contact details and any relevant accreditations or insurance information.

Why Your Insurer Needs It

Commercial property insurance for food businesses — whether you run a restaurant in Tenby, a pub kitchen in Haverfordwest or a takeaway in Pembroke Dock — typically includes conditions relating to the maintenance of fire risk systems. Extract cleaning is among the most common and most specifically referenced conditions.

In the event of a kitchen fire, your insurer will investigate the maintenance history of your extract system. They will ask for post-clean certificates. If you cannot produce them — or if the certificates show gaps in your cleaning schedule that don't align with the level of use in your kitchen — the claim investigation becomes significantly more complicated.

The certificate is not just a receipt for work done. It is your evidence of responsible management, and it is what stands between your business and a problematic insurance claim following a kitchen incident.

Why EHO Inspectors May Ask for It

Environmental health officers (EHOs) conducting food hygiene inspections are not primarily looking at your extract cleaning records — their focus is on food safety. However, a well-maintained kitchen with complete compliance documentation, including extract cleaning records, demonstrates a positive overall management approach that can contribute to a higher food hygiene rating.

In some situations — particularly where an EHO visits following a complaint or incident — the state of your kitchen's extract system and the availability of cleaning records may be specifically reviewed.

Keeping Your Records in Order

The practical advice is simple: keep every post-clean certificate you receive, filed in date order, alongside your fire risk assessment and other kitchen compliance documentation.

A folder or binder with: - Your current fire risk assessment - All post-clean certificates (keep for at least three years) - Service records for kitchen equipment - Food hygiene documentation

...represents a complete compliance record that you can present confidently to your insurer, a fire safety inspector or an EHO.

What If You Can't Find Your Old Certificates?

If you have had professional cleans in the past but cannot locate the documentation, contact your previous contractor and request copies. Many reputable contractors keep records and can reissue documentation.

If you have no records at all — either because previous cleans were not professional cleans, or because documentation was never produced — the practical solution is to arrange a new professional clean and ensure compliant documentation is produced this time. Going forward with a properly documented programme is the important thing.
