Fire, insurance & risk
It isn't box-ticking. A tenant's certificate protects the freeholder's own cover, satisfies the lease, and keeps the whole building insurable.
The short answer
Landlords collect tenants' TR19 certificates because the freeholder's own buildings insurance carries the same cleaning condition, because the lease usually requires it, and because one tenant's dirty duct can undermine cover for the whole building. The certificate is how the landlord proves the building is compliant - to their insurer, and at renewal.
Reason one: the buildings policy
The landlord's buildings or all-risks policy typically contains the same requirement your own policy does: kitchen extract systems maintained and cleaned to a recognised standard, in practice TR19 Grease, at intervals matched to use. The difference is scale. A tenant's un-evidenced grease clean is not just a risk to that tenant - it can undermine the landlord's cover for the entire structure, including the other units.
So the landlord polices the requirement upstream. Collecting each tenant's post-clean certificate is how the freeholder demonstrates to their own insurer that every grease-generating demise in the building is being maintained - the evidence that keeps the buildings policy valid.
Reason two: the lease
Most commercial leases for catering units covenant the tenant to maintain the extract system to standard and to allow the landlord audit or inspection rights. The certificate is your proof that the covenant has been performed. Ask a landlord why they want it and the honest answer is that the lease entitles them to it - and that at end of term, documented TR19 compliance is commonly required as part of the handover. Failure there can mean a withheld deposit or a dilapidations claim.
Delegating the cleaning task does not remove the statutory fire-safety duty from anyone - in a shared building there is usually more than one Responsible Person - but the lease decides who arranges and pays, and the certificate is the receipt.
What they do with it
A collected certificate goes into the building's compliance file, is produced to the buildings insurer at renewal or after a loss, and feeds the coordinating whole-building fire risk assessment. Increasingly, landlords will not accept a certificate at face value: they require the clean to be done by a BESA-registered contractor, retain the right to audit, and may commission an independent TR19 check of shared risers - because a certificate alone is not proof of the work behind it, only proof that a clean was claimed.
For a tenant, the practical takeaway is simple: keep your TR19 certificates current and hand them over promptly. It is not the landlord being difficult - it is the mechanism that keeps the whole building insurable, yours included.
Questions
Because the freeholder's buildings insurance carries the same TR19 cleaning condition your policy does, the lease usually requires compliance, and one tenant's dirty duct can undermine cover for the whole building. The certificate is their proof of compliance.
Yes. On a shared or all-risks buildings policy, an un-evidenced or overdue clean in one demise can leave the whole building's cover challengeable after a fire.
Most catering leases covenant the tenant to maintain the extract system to standard and grant the landlord audit or inspection rights. Documented compliance is also commonly required at end-of-term handover.
Increasingly no. Landlords often require the clean to be carried out by a BESA-registered contractor and may audit shared risers independently, because a certificate is only proof a clean was claimed, not proof of the work.
No. The lease decides who arranges and pays, but the statutory fire-safety duty stays with the Responsible Person. The certificate is the receipt, not a transfer of liability.
