Cooker hood installation in Chislehurst

When does cooker hood installation make sense in Chislehurst?

If condensation runs down the windows of your Chislehurst kitchen whenever you cook, the hood may be recirculating, undersized or ducted through a long, flexible run.

People in flats across Greater London sometimes rely on recirculating hoods because an outside vent needs consent from the building's owners, and want to know what else improves ventilation. Kitchens in every part of Chislehurst are covered, and the survey visit is free wherever you are in Greater London.

What is in a typical job?

The exact scope is agreed after the survey, but a typical job in Chislehurst covers:

Short, straight runs of rigid ducting wherever the route allows
Island and ceiling hoods fixed into the ceiling structure by two people
Spillage test by a Gas Safe registered engineer where an open-flued appliance is present
Core drilling through the outside wall and an external grille fitted and sealed
Hood fixed at the height set by the hood and hob manufacturers
Recirculating hoods fitted with carbon filters, and their limits explained

Local homes and their kitchens

You will find Victorian and Edwardian terraces, conversion flats, mansion block flats and 1930s semis throughout Greater London. Victorian terraces often have a narrow galley beside the side return, while conversion flats and mansion blocks usually fit the kitchen into a small room or along one living-room wall.

Permit parking, red routes and flats without lifts are common, so parking suspensions, stair carries and lift bookings may need arranging before delivery day. London's mains water is hard, so limescale builds quickly on taps and boiling water taps, and a scale-reducing filter is worth planning in.

Do you need approval for cooker hood installation in Chislehurst?

In England, Approved Document F guidance for kitchen extract is about 30 litres per second from a cooker hood extracting outside, or 60 litres per second from a fan elsewhere in the room. A recirculating hood does not remove moisture, so another means of extract is usually needed. A new vent through the outside wall of a flat may need planning permission and the freeholder's consent, and an open-flued gas appliance in the room calls for a spillage test.

Conservation areas are widespread across London, so a new extractor vent on a front wall may need permission, and leaseholders usually need the freeholder's written consent first.

Planning ahead

If your Chislehurst home is listed, or in a building with strict rules on outside changes, check what is allowed before any hole is cut for a duct.
Choose a hood at least as wide as your hob, and compare its stated extraction rate with the size of the room before you buy.
Check whether your Chislehurst home has an open-flued boiler or gas fire, and mention it at the survey so a spillage test can be planned.
Keep the duct run short and straight with rigid ducting, because every bend and extra metre of flexible hose reduces how much air the hood moves.

Why might a cooker hood need a spillage test?

Because a hood pulling air out of a room can draw fumes back down the flue of an open-flued gas appliance, such as some older boilers or gas fires. Where the kitchen, or a room open to it, has one, a Gas Safe registered engineer should carry out a spillage test with the hood running at full speed. Room-sealed boilers are not affected in the same way.

How high should a cooker hood be above the hob?

At least the minimum distance given by the manufacturers. Both the hood and the hob instructions set a minimum gap between them, and where they differ the greater figure should be used. Gas hobs usually need more clearance than induction. A hood fitted too low is a fire risk, while one fitted much higher than recommended captures less steam.

Should I choose a ducted or a recirculating cooker hood?

A ducted hood is usually more effective, because it takes steam, smoke and smells outside. A recirculating hood passes air through grease and carbon filters and returns it to the room, so it deals with grease and smells but not moisture, and another means of extract is usually needed. Recirculating suits kitchens with no practical duct route, and its carbon filters need replacing.
