What Happens If You Fail a TR19 Inspection?

For commercial kitchen operators, a TR19 inspection is not a bureaucratic formality — it is a direct assessment of whether your extraction system is safe, compliant, and insurable. Failing an inspection has serious consequences that extend well beyond a cleaning bill.

This guide explains what a TR19 inspection involves, what constitutes a failure, and — critically — what the consequences are for your insurance, your business, and your legal obligations.

What Is a TR19 Inspection?

A TR19 inspection is a formal assessment of your kitchen extraction system against the BESA TR19 standard. It is carried out either:

As part of a cleaning visit — a qualified TR19 contractor assesses the system before and after cleaning
As a standalone audit — an independent inspector assesses the system's condition and compliance
By an insurer's risk surveyor — as part of a policy renewal or following a claim
By a fire risk assessor — as part of a statutory fire risk assessment

The inspection covers the entire extraction system: canopy, filters, ductwork, fan unit, and discharge point. The inspector measures grease deposit thickness at multiple points and assesses whether the system meets the TR19 cleanliness standard.

What Constitutes a Failure?

Under the TR19 standard, the key measure of compliance is grease deposit thickness. The standard sets maximum acceptable deposit levels at various points in the system:

Location — Maximum Acceptable Deposit
--- — ---
Canopy and plenum — 0.8mm
Horizontal ductwork — 0.8mm
Vertical ductwork — 0.8mm
Fan housing — 0.8mm

A deposit exceeding 0.8mm at any measured point constitutes a non-compliance finding. In practice, inspectors also consider:

The overall condition of the system (corrosion, structural damage)
Whether access panels are present and correctly positioned
Whether the system has been cleaned at the required frequency
Whether previous cleaning records and certificates are available

The Consequences of Failure

1. Insurance Implications

This is the most immediate and serious consequence for most kitchen operators. If a TR19 inspection reveals that your extraction system is non-compliant, your insurer may:

Decline a fire claim if the non-compliance is found to have contributed to the fire
Void your policy if the non-compliance constitutes a material breach of policy conditions
Require immediate remediation as a condition of continuing cover
Increase your premium at renewal to reflect the elevated risk

Many commercial kitchen insurance policies contain an explicit condition requiring TR19 compliance. If you cannot produce a valid TR19 certificate when asked, you may be in breach of your policy regardless of whether a fire has occurred.

2. Enforcement Action

A failed TR19 inspection may also trigger enforcement action from:

The local fire authority — if the inspection is part of a fire risk assessment, a non-compliant extraction system may result in an enforcement notice requiring remediation within a specified timeframe
Environmental Health Officers — EHOs have powers to close premises that present an imminent risk to public health or safety
The Health and Safety Executive — in serious cases, the HSE may investigate and prosecute under the Health and Safety at Work Act 1974

3. Reputational Damage

For restaurants, hotels, and food businesses, a failed inspection that becomes public knowledge can cause significant reputational damage. Food hygiene ratings and fire safety records are increasingly scrutinised by customers and review platforms.

Why Do Kitchens Fail TR19 Inspections?

The most common reasons for TR19 non-compliance are:

Insufficient cleaning frequency — the system has not been cleaned at the intervals required by TR19 or the insurance policy
Inadequate cleaning quality — previous cleaning was carried out by an unqualified contractor who did not meet the TR19 standard
Missing access panels — sections of ductwork cannot be cleaned because access panels are absent or incorrectly positioned
No documentation — previous cleaning was carried out but no TR19-compliant service report was produced
High-risk cooking type — the cooking operation generates grease at a rate that requires more frequent cleaning than the operator realised

What to Do If You Fail an Inspection

If your extraction system fails a TR19 inspection, the priority is to:

Commission an immediate TR19 clean from a qualified contractor
Notify your insurer or broker — do not attempt to conceal a non-compliance finding
Obtain a TR19-compliant service report confirming the system has been remediated
Review your cleaning schedule to ensure future compliance
Consider additional access panels if the inspection identified inaccessible sections

At BlueTick Extraction Hygiene, we regularly receive calls from kitchen operators who have just received a non-compliance finding from an insurer or fire risk assessor. We can typically arrange an emergency clean within 48–72 hours and provide a TR19 certificate that satisfies the insurer's requirements.

How to Ensure You Never Fail

The most reliable way to avoid a failed inspection is to:

Establish a cleaning schedule based on your TR19 risk category and insurance requirements
Use a qualified TR19 contractor who provides compliant documentation after every visit
Keep your certificates — maintain a file of all TR19 service reports going back at least three years
Review your policy annually to confirm the cleaning frequency required by your insurer
Book your next clean before the current certificate expires

BlueTick Extraction Hygiene provides a 12-month follow-up reminder service for all clients. We will contact you 4–6 weeks before your next clean is due to ensure you never let your compliance lapse.

Frequently Asked Questions

Q: Can I appeal a failed TR19 inspection?

You can commission an independent inspection to verify the findings. However, if the deposit measurements are above the TR19 threshold, the non-compliance is objective. The appropriate response is to commission a clean and obtain a new certificate.

Q: How quickly can I get a TR19 clean after a failed inspection?

BlueTick Extraction Hygiene can typically arrange an emergency clean within 48–72 hours. Contact us directly on 07840 992 246 to discuss your requirements.

Q: Will my insurer be notified if I fail an inspection?

If the inspection is carried out by your insurer's risk surveyor, yes. If it is carried out by an independent contractor or fire risk assessor, you have an obligation to notify your insurer of any material change in risk — which a non-compliant extraction system constitutes.

Q: Does a failed inspection affect my food hygiene rating?

Not directly. Food hygiene ratings are assessed by Environmental Health Officers against different criteria. However, a seriously non-compliant extraction system may be noted in an EHO inspection report and could affect your overall assessment.
