Cooker hood installation in Portsmouth

What prompts cooker hood installation in Portsmouth?

People in flats across Hampshire sometimes rely on recirculating hoods because an outside vent needs consent from the building's owners, and want to know what else improves ventilation.

If your Portsmouth house has thick solid walls, core drilling a neat hole for the duct takes the right equipment and careful positioning of the outside grille. If your home is in Portsmouth or close by in Southsea or Gosport, the same survey, quote and fitting process applies.

What does the job involve?

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

Spillage test by a Gas Safe registered engineer where an open-flued appliance is present
Island and ceiling hoods fixed into the ceiling structure by two people
Survey of the hob position, duct route, outside wall and any open-flued appliance
Recirculating hoods fitted with carbon filters, and their limits explained
Short, straight runs of rigid ducting wherever the route allows
Power supply connected by an electrician and tested to BS 7671

Local homes and their kitchens

The housing mix across Hampshire includes Victorian terraces, 1930s semis, post-war estate houses and thatched and brick cottages, so no two kitchen fits are quite alike. Terraces in Southampton and Portsmouth often have a narrow back kitchen, while post-war estate houses tend to have a compact rectangular room suited to an L-shape.

Water across Hampshire is mostly hard, largely from chalk sources, so limescale on taps and boiling water taps is common and a filter can help. Dense terraced streets can be very tight for parking, and New Forest lanes and village roads may limit the size of delivery vehicle.

What rules apply to cooker hood installation in Portsmouth?

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.

Homes within the New Forest or South Downs national parks, listed cottages and conservation areas may need consent for a new extractor vent or alterations to historic features.

Practical advice for Portsmouth homeowners

If you live in a flat in Hampshire, ask the freeholder, factor or managing agent about outside vents before you buy a ducted hood.
If your Portsmouth 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.
For an island hood in your Portsmouth kitchen, settle the hood position before the ceiling is boarded, so timber supports can be added in the right place.
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.

Questions about cooker hood installation in Portsmouth

How much does cooker hood installation cost in Portsmouth?

Guide prices in Portsmouth are about £140 to £280 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 Portsmouth as well?

Yes. As well as Portsmouth itself, we cover the rest of Hampshire and nearby towns such as Southsea and Gosport. The process is the same wherever the kitchen is.

Can a ducted cooker hood be fitted in a flat?

Often, but check consents first. A new vent through the outside wall of a flat may need planning permission and the freeholder's written consent, and some leases do not allow it at all. Where an outside vent is not possible, a recirculating hood can be fitted, with a separate extract fan or other ventilation dealing with moisture. Listed buildings may also need listed building consent.

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.

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.
