Duct cleaning removes grease, dust and debris from inside ventilation and kitchen extract systems, from the canopy and filters through the ductwork to the fan. We clean to BESA TR19 and provide a post-clean report in the TR19 format, with photographs and measured readings.

How it works

Grease builds up inside kitchen extract ducts and is a serious fire risk. BESA TR19 Grease recommends minimum cleaning intervals of every 3 months for heavy use (12 to 16 hours a day), 6 months for moderate use and 12 months for light use, with mean grease deposits kept below 200 microns between cleans and anything at 500 microns or more cleaned straight away.

General ventilation ductwork collects dust and debris that reduce airflow and air quality; TR19 Air covers inspection and cleaning of these systems. Many insurers expect regular cleaning to a recognised standard and may ask for the reports after a claim.

The rules that apply

England

In England, ventilation is covered by Part F of the Building Regulations and its guidance, Approved Document F (2021 edition). Kitchen extract is commonly cleaned to BESA TR19 Grease, and gas appliances are normally interlocked with the ventilation following BS 6173.

Wales

Wales has its own Part F ventilation guidance, published by the Welsh Government, and work is checked by building control. TR19 Grease cleaning and BS 6173 gas interlocks apply in Wales as elsewhere, with planning conditions set by your council.

Scotland

In Scotland, ventilation is covered by the Building (Scotland) Regulations and section 3 of the Technical Handbooks, and most building work needs a building warrant first. TR19 Grease cleaning and BS 6173 gas interlocks apply in Scotland too, and new flues usually need planning permission and a building warrant.

Northern Ireland

In Northern Ireland, ventilation is covered by the Building Regulations (Northern Ireland) and Technical Booklet K. TR19 Grease cleaning and BS 6173 gas interlocks apply in Northern Ireland too, with planning handled by your council.

Questions people ask

How often should kitchen extraction be cleaned?

Under BESA TR19 Grease, kitchen extract systems should be cleaned at least every 3 months for heavy use (12 to 16 hours a day), every 6 months for moderate use and every 12 months for light use.

How much does kitchen duct cleaning cost?

A TR19 Grease clean of a single canopy system typically costs £395 to £895 excluding VAT, depending on duct length and access.

What is in a TR19 report?

A TR19 post-clean report includes before-and-after photographs, grease or dust deposit measurements, a summary of work done, and notes on any areas that could not be reached.

Do insurers require TR19 cleaning?

Many insurers expect kitchen extract to be cleaned regularly to a recognised standard such as TR19 and may ask for the reports, particularly after a fire.

Can you clean outside opening hours?

Yes. Most kitchen cleans are done overnight or before service.

What if parts of the duct cannot be reached?

We report them, and can fit access panels so they can be cleaned next time.
