Stainless steel extraction canopy over a commercial kitchen range

Commercial kitchen extraction captures heat, grease and smoke at the cooking line through a canopy with grease filters, then carries it away through ductwork to a fan and discharge point, with fresh make-up air brought back in. We design and install canopies, fans, ductwork, make-up air and the gas interlock that links them.

How it works

Canopies need to overhang the cooking equipment, use grease filters suited to the cooking, and have access for cleaning. Where gas appliances are used, the gas supply is normally interlocked with the ventilation so cooking cannot run without extract, as BS 6173 sets out. Planning conditions often require odour control and limits on noise at the discharge.

We fit out new restaurants, cafés, takeaways and staff canteens, and replace or extend extract when menus or equipment change.

Options we fit

Wall and island canopies

Stainless steel canopies with baffle grease filters and lighting.

Extract fans and ductwork

Fans sized to the canopy, with access panels for cleaning.

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 much does a commercial kitchen extraction system cost?

A canopy and extract system for a café or takeaway (canopy up to 2 metres) typically costs £5,950 to £11,950 excluding VAT, and a restaurant system with a 3 to 4 metre canopy and make-up air £12,950 to £29,950.

Do I need a gas interlock?

Commercial kitchens with gas appliances normally need the gas supply interlocked with the ventilation, so cooking cannot take place without extract running, following BS 6173.

Do I need planning permission for kitchen extraction?

A new external flue or discharge often needs planning permission, and conditions commonly cover odour control and noise. We can supply technical details for your application.

What is make-up air?

Make-up air is fresh air brought back into the kitchen to replace what the canopy extracts, so doors do not slam and gas appliances burn properly.

How often does kitchen extract need cleaning?

Under BESA TR19 Grease, minimum cleaning intervals are every 3 months for heavy use, 6 months for moderate use and 12 months for light use.

Can you work around opening hours?

Yes. Installs and changeovers can be scheduled outside trading hours.
