Cooker hood installation in Welwyn Garden City

Thinking about cooker hood installation in Welwyn Garden City?

If your Welwyn Garden City kitchen has an older open-flued boiler, fitting a stronger hood needs care, as it can affect the flue and should be followed by a spillage test.

If your Welwyn Garden City house has thick solid walls, core drilling a neat hole for the duct takes the right equipment and careful positioning of the outside grille. Welwyn Garden City sits about 13 miles north-east of Watford, and our Hertfordshire coverage takes in everything in between.

Every kitchen is different, so we confirm the scope in writing. Most jobs of this kind include:

Core drilling through the outside wall and an external grille fitted and sealed
Power supply connected by an electrician and tested to BS 7671
Survey of the hob position, duct route, outside wall and any open-flued appliance
Short, straight runs of rigid ducting wherever the route allows
Hood fixed at the height set by the hood and hob manufacturers
Island and ceiling hoods fixed into the ceiling structure by two people

Local homes and their kitchens

In and around Welwyn Garden City, homes range across 1930s semis, post-war new town houses, Victorian terraces and new-build estates. Stevenage and Hemel Hempstead new-town houses often have a small galley, while 1930s semis tend to have a narrow kitchen beside the dining room.

Hertfordshire's water is very hard, mostly drawn from chalk, so limescale on taps and boiling water taps is common and a softener or filter is worth considering. Commuter-town streets often have tight parking, and estate houses with shared parking courts can mean carrying units some distance to the front door.

Do you need approval for cooker hood installation in Welwyn Garden City?

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.

A kitchen fit needs no planning permission, but listed buildings and conservation areas, including parts of St Albans and Welwyn Garden City, may need consent for external vents.

Tips before you start

If your Welwyn Garden City 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.
Ask for rigid ducting rather than flexible hose wherever the route allows, as it moves more air, gathers less grease and is usually quieter.
If the kitchen has an open-flued boiler or gas fire, a Gas Safe registered engineer should carry out a spillage test after the hood is fitted.

Questions about cooker hood installation in Welwyn Garden City

How much does cooker hood installation cost in Welwyn Garden City?

Guide prices in Welwyn Garden City are about £130 to £260 including VAT for a like-for-like cooker hood swap. The final price depends on the size of the kitchen and what is moving, and is set out in an itemised written quote.

Do you work near Welwyn Garden City as well?

Yes. As well as Welwyn Garden City itself, we cover the rest of Hertfordshire and nearby towns such as Hatfield and Hertford. The process is the same wherever the kitchen is.

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.
