TR19 is the BESA (Building Engineering Services Association) standard for grease exhaust cleanliness in commercial kitchen extract systems. It's the benchmark most UK insurers and fire enforcement bodies use to judge whether a kitchen extract system is compliant.

Yes. The initial inspection, measurements and written workplan are free, with no obligation to use Yes Chef for any work that follows. Use the plan yourself, with your existing contractor, or with us.

You get a clear, written plan showing exactly what's non-compliant and what needs doing to fix it. You're free to action that yourself, use your own contractor, or come back to Yes Chef for the work — there's no obligation either way.

TR19 sets cleaning frequency by usage risk category (for example, how many hours per week the kitchen operates and how it's used) rather than a single fixed interval — the inspection will confirm what applies to your specific system.

A general clean removes visible grease. A TR19-certified clean is measured against stated deposit-thickness thresholds before and after, photographically documented, and certified by a TR19-qualified technician — producing evidence you can hand to an insurer or auditor, not just a tidier kitchen.

Yes — Yes Chef works directly with restaurant groups, pub chains and multi-site hospitality operators, as well as the facilities management companies managing compliance on their behalf.

Every Yes Chef certificate is issued and signed by a suitably qualified Yes Chef technician who has personally verified the evidence behind it — the initial inspection, the photographs and the post-clean inspection.
