Restaurant insurers reject renewal applications every week because TR19 certificate documentation fails to meet regulatory standards. The certificate proves your kitchen extraction cleaning meets the 200-micron grease threshold required under TR19 compliance regulations.
Key Takeaways:
- TR19 certificates must be issued by BESA-registered contractors to meet insurer requirements
- Valid certificates include WFTT/DTT grease test results showing <200-micron accumulation
- Certificate costs range from £150-400 depending on system size and cleaning complexity
What Is a TR19 Certificate and What Does It Actually Prove?
A TR19 certificate is post-cleaning documentation that proves your kitchen extraction system meets the grease accumulation standards specified in the TR19 Grease specification. This means the certificate serves as legal evidence that your extraction cleaning complies with fire safety regulations and insurer requirements.
The certificate documents that grease buildup across your extraction system remains below the 200-micron threshold after professional cleaning. This threshold exists because grease accumulation above 200 microns creates significant fire risk in commercial kitchens. The TR19 Grease specification sets this limit as the maximum acceptable residue following extraction cleaning.
What the certificate actually proves matters more than its existence. Valid TR19 certificates confirm that WFTT (Wet Film Thickness Testing) or DTT (Dry Film Thickness Testing) measured grease levels across critical system components – ductwork, fan housings, canopies, and access panels. The testing identifies problem areas where grease persists above safe levels.
The certificate also documents the cleaning scope, contractor credentials, and specific test locations within your extraction system. Insurance companies examine these details during claims investigations. A certificate without proper grease measurement data gets rejected by insurers, leaving you liable for fire damage costs.
Who Can Issue TR19 Certificates and What Qualifications Are Required?
BESA-registered contractors issue valid TR19 certificates that insurers accept for compliance documentation. This means only cleaning companies holding current BESA (Building Engineering Services Association) registration can provide legally recognized certification.
| Certification Type | BESA-Registered | Non-BESA Contractor |
|---|---|---|
| Insurance Acceptance | Yes – meets regulatory standards | No – lacks legal authority |
| Training Requirements | BESA TR19 certification course | No standardized training |
| Quality Assurance | Regular audits and compliance checks | No oversight mechanism |
| Equipment Standards | Calibrated WFTT/DTT testing tools | Variable equipment quality |
| Certification Authority | Legal authority under TR19 standard | Cannot issue valid certificates |
BESA registration requires contractors to complete specialized training on TR19 Grease standards, fire safety regulations, and proper testing procedures. Registered contractors must maintain calibrated testing equipment and submit to regular compliance audits. They also carry professional indemnity insurance that covers certification errors.
Non-BESA contractors can clean your extraction system but cannot issue certificates that satisfy legal requirements. Some cleaning companies use unofficial certificates or generic documentation. Insurance companies reject these certificates because they lack regulatory backing. Using non-BESA certificates during an insurance claim can void your coverage entirely.
The qualification gap matters for liability. BESA contractors undergo continuous professional development and face regulatory oversight. Their certification carries legal weight because BESA maintains industry standards under government recognition.
What Information Must a Valid TR19 Certificate Include?
TR19 certificates contain specific data sections mandated by the TR19 Grease standard to document cleaning effectiveness and compliance status.
Required certificate elements include:
WFTT/DTT testing results – Grease thickness measurements from each tested location, showing micron readings below the 200-micron threshold across all system components.
Contractor identification details – BESA registration number, company credentials, and certifying technician qualifications to establish legal authority for certification.
System mapping and cleaning scope – Detailed documentation of extraction system layout, access points cleaned, and areas requiring follow-up attention during future cleaning cycles.
Post-clean verification photographs – Visual evidence showing cleaned surfaces, test measurement locations, and any areas where grease accumulation required additional treatment.
Compliance declaration statement – Written confirmation that cleaning meets TR19 Grease specification requirements and relevant fire safety regulations under the Regulatory Reform (Fire Safety) Order 2005.
Next cleaning recommendation – Suggested timeline for subsequent cleaning based on kitchen usage patterns, cooking methods, and grease accumulation rates observed during current cleaning.
The certificate format follows BESA templates that insurers recognize. Certificates missing any required section fail compliance verification. Some contractors issue abbreviated certificates to reduce costs, but these documents cannot satisfy insurance or regulatory requirements.
Testing data must specify exact measurement locations within your extraction system. Generic statements about “system cleanliness” without supporting grease measurements get rejected during insurance claims investigations.
Why Do Insurance Companies Demand TR19 Certificates?
The Regulatory Reform (Fire Safety) Order 2005 requires commercial kitchen operators to implement fire prevention measures, making TR19 certificates essential documentation for legal compliance. Insurance companies demand these certificates because they prove you’ve taken reasonable steps to prevent extraction system fires.
Commercial kitchen fires cost UK insurers £300 million annually, with 70% tracing back to grease accumulation in extraction systems. TR19 certificates demonstrate that grease levels remain within safe limits, reducing fire risk significantly. This documentation helps insurers assess policy risk and determine coverage terms.
Insurance companies face substantial liability when kitchen fires spread beyond the building of origin. Proper extraction cleaning prevents grease ignition that can destroy entire restaurant premises and damage neighboring properties. The certificate provides evidence that fire prevention obligations were met before any incident occurred.
Claims investigators examine TR19 certificates to determine coverage validity after kitchen fires. Missing certificates or non-compliant documentation can void coverage entirely, leaving restaurant owners personally liable for fire damage costs. The certificate timeline also matters – cleaning performed years before a fire carries less weight than recent certification.
Insurers use TR19 compliance as a rating factor for commercial kitchen policies. Restaurants with current certificates often receive lower premiums because documented fire prevention reduces claim probability. Some insurers refuse coverage entirely without valid TR19 certification.
How Much Does a TR19 Certificate Cost and How Long Is It Valid?
TR19 certificate costs depend on extraction system complexity, kitchen size, and cleaning requirements that vary significantly between different commercial kitchen setups.
| Kitchen Type | Certificate Cost Range | Validity Period |
|---|---|---|
| Small takeaway (single extract) | £150-250 | 12 months |
| Medium restaurant (2-3 extracts) | £200-350 | 6-12 months |
| Large hotel kitchen (multiple systems) | £300-400 | 3-6 months |
| High-volume operations | £350-500 | Monthly inspection required |
Cost factors include system accessibility, grease accumulation levels, and additional cleaning required to meet the 200-micron threshold. Heavily contaminated systems need extended cleaning time, increasing certification costs. Hotels with multiple extraction points require comprehensive testing across all systems, raising the total expense.
Certificate validity periods reflect kitchen usage intensity rather than arbitrary timelines. High-volume kitchens operating 12+ hours daily accumulate grease faster than occasional-use facilities. BESA contractors recommend cleaning frequency based on cooking methods, extraction airflow rates, and observed grease buildup patterns.
Some contractors include certification costs within their cleaning quotes, while others charge separately for testing and documentation. Always confirm that TR19 certification is included before booking kitchen extraction cleaning services. Cheaper cleaning without proper certification saves nothing if your insurance claim gets rejected.
Frequently Asked Questions
Can I get a TR19 certificate without using a BESA-registered contractor?
No, only BESA-registered contractors can issue valid TR19 certificates that insurers will accept. Non-BESA cleaning companies can clean your extraction system, but they cannot provide the certification documentation required for compliance.
How long does it take to receive my TR19 certificate after cleaning?
BESA-registered contractors typically issue TR19 certificates within 24-48 hours of completing the cleaning and WFTT testing. The certificate is generated once all grease test results confirm the 200-micron threshold is met.
What happens if my extraction system fails the grease testing for TR19 certification?
If WFTT testing shows grease accumulation above 200 microns, the contractor must re-clean those sections and retest before issuing the certificate. This additional work is typically included in the quoted price from reputable contractors.
