What is a kitchen extension?
A kitchen extension is an extension designed around a new kitchen, usually an open-plan kitchen, dining and family space at the back of the house. We build the extension and fit the kitchen as one project, so plumbing, electrics and lighting are planned around the layout from the start.
How much does a kitchen extension cost in Milford Haven?
In Milford Haven, a kitchen extension typically costs £2,050–£3,150 per m² including a mid-range kitchen, including VAT at 20% (standard rate). For a typical 22 m² project that is roughly £45,000–£69,500. The guide for Milford Haven reflects typical costs in Wales, roughly 8% below the UK-wide figure.

Do you need planning permission for a kitchen extension in Milford Haven?
Approvals for a kitchen extension in Milford Haven follow the rules for Wales. In Wales a single-storey rear extension is often permitted development: up to 4 metres beyond the rear wall and up to 4 metres high, with eaves no higher than 3 metres within 2 metres of a boundary and no more than half the land around the original house covered. Wales has no larger home extension prior approval route, so deeper extensions need a planning application, as do extensions to flats, listed buildings and houses whose rights have been removed.
Building regulations in Wales are set by the Welsh Government. Approval comes from the council’s building control service or a registered building control approver, with inspections during the work and a completion certificate at the end.
We check this for your address before design work starts, so there are no surprises later.
What we handle
On a typical kitchen extension we handle:
- Flooring and decoration
- Kitchen fitting, worktops and splashbacks
- Drainage and water supply positioned for the sink and appliances
- Electrics, lighting plan and sockets
- Kitchen layout planned alongside the extension design
- Extraction ducted to outside
How long does it take?
Expect 11 to 16 weeks on site, including kitchen fitting. Design and approvals come first and typically take 6 to 12 weeks, depending on the approval route.

Questions about kitchen extensions in Milford Haven
Do I need planning permission for a kitchen extension in Milford Haven?
In Wales a single-storey rear extension is often permitted development: up to 4 metres beyond the rear wall and up to 4 metres high, with eaves no higher than 3 metres within 2 metres of a boundary and no more than half the land around the original house covered. Wales has no larger home extension prior approval route, so deeper extensions need a planning application, as do extensions to flats, listed buildings and houses whose rights have been removed.
Who approves a kitchen extension in Milford Haven?
Planning matters in Milford Haven go to the council covering your address, and the work needs building control approval. We prepare and submit the applications for you.
Is underfloor heating worth it?
In a large open-plan space it frees wall space for units and glazing and gives even heat. It is easiest to fit during the build.
Do I need extraction to outside?
Building regulations require kitchen extract ventilation. Ducting to an outside wall is the most effective option and is planned during the build.
How much does a kitchen extension cost in Milford Haven?
In Milford Haven, a kitchen extension typically costs £2,050–£3,150 per m² including a mid-range kitchen, including VAT at 20% (standard rate). A typical 22 m² project comes to roughly £45,000–£69,500. Your fixed price depends on the survey and drawings.
Should the kitchen be designed before the extension?
Yes. Knowing where the sink, hob and island will go lets us place drains, ducting, sockets and windows correctly during the build.
