Why It Matters Who You Choose
There are companies who advertise kitchen extract cleaning but do not work to TR19 Grease standards. As well as the increased fire risk, the difference between a compliant clean and a substandard one can be the difference between passing an inspection or failing one, and between a valid insurance claim or a rejected one.
Choosing the wrong contractor cannot only leave your system at risk but also your expose your business to considerable liabilities.
Check TR19 Training and Competence
TR19 Grease requires that operatives are formally trained in the specific techniques and safety requirements of grease ventilation cleaning. Ask whether the company's operatives hold BESA-recognised training qualifications.
A respectable contractor will be able to provide evidence of training without hesitation. Be cautious of companies that claim TR19 compliance but cannot demonstrate how their staff are qualified.
Ask About Post-Clean Verification
A compliant clean is not just about removing visible grease. TR19 Grease requires post-clean verification to confirm that grease deposits have been reduced to below 50 microns, measured using a Deposit Thickness Test (DTT) or Wet Film Thickness Test (WFTT).
Your contractor should be able to explain their verification process and include the results in their report. It is a clear red flag if they do not mention post-clean test results.
Demand Proper Documentation
Every TR19 Grease ventilation cleaning service should come with a comprehensive post-clean report. This should include the service date and list all areas cleaned. Photographic evidence of the condition before and after cleaning should also be provided, as well as any areas of concern or limited access. Post-clean verification test results, and recommendations for the next cleaning interval should also be clearly specified.
This documentation is essential for insurance compliance, fire safety audits, and Environmental Health inspections. If a contractor cannot provide this level of reporting, they may be deemed as not following TR19 Grease standards.
Check Waste Disposal and Insurance
Waste removed during grease ventilation cleaning must be disposed of in line with Local Authority guidelines. Ask your contractor for their waste carrier registration details.
Also check that they hold appropriate public liability insurance and employer's liability insurance. A competent contractor will be able to provide copies of all relevant certificates on request.
Look for Full System Coverage
Some contractors might only clean the easily accessible parts — the canopy and filters, whilst still producing a ventilation cleaning certificate. A TR19 Grease-compliant clean covers the entire system from canopy to discharge including the ductwork, fan unit, and discharge point.
Ask your contractor for a specific scope of works. If they cannot clean the full system, they should not be issuing certification that suggests otherwise.
