View all services →TR19 is the UK industry standard for grease extraction cleaning in commercial kitchens, produced by BESA (the Building Engineering Services Association). It defines exactly how kitchen canopies, ductwork, filters, and fans must be cleaned to be legally compliant.
It's the only standard recognised by insurers, fire inspectors, and the law. A generic clean from a non-accredited contractor does not satisfy TR19 requirements. Only a BESA VHR-registered contractor like Hy5 can provide documentation that will hold up under scrutiny.
If your extraction system hasn't been cleaned to TR19 standard, your insurance policy may be invalid right now, and you may be in breach of fire safety law.
Maximum grease deposit permitted under TR19. We measure and document readings on every job and issue a certificate showing proof.
Extraction system grease buildup is the leading cause of commercial kitchen fires in the UK.
Maximum recommended cleaning interval for most commercial kitchens, more frequently for high-use operations.

BESA VHR membership is the only accreditation recognised by UK insurers as proof of compliant TR19 cleaning. Without it, your cleaning certificate may not be accepted.

Hy5 holds CHAS Elite accreditation, the highest level of contractor health and safety pre-qualification in the UK.

As active members of the Cumbria Chamber of Commerce, Hy5 is a trusted, established local business, professionally endorsed and rooted in the community.
"I can actually hear the kitchen extract system working and the extract above the dishwash nearly pulled the sheet of blue roll out my hand when I was showing the management team how effective the clean was! The lads grafted the entire time, and the job has made a huge difference to the guys working in the kitchen. I am over the moon with the results!"
