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 Holyhead?
In Holyhead, 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. Building costs in Wales run about 8% below the UK average, and the figures for Holyhead are adjusted to reflect that. Design, structural calculations and council fees are extra.

Do you need planning permission for a kitchen extension in Holyhead?
Approvals for a kitchen extension in Holyhead 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.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
What we handle
From survey to sign-off, the job normally involves:
- Extension structure, roof and glazing
- Extraction ducted to outside
- Flooring and decoration
- Kitchen fitting, worktops and splashbacks
- Building control sign-off
- Drainage and water supply positioned for the sink and appliances
How long does it take?
Allow 11 to 16 weeks on site, including kitchen fitting. Before that, surveys, drawings and approvals usually take 6 to 12 weeks, longer if the council asks for changes.

Questions about kitchen extensions in Holyhead
Can I buy my own kitchen?
Yes. You can supply it and we fit it, or we supply it as part of the price. Either way we coordinate deliveries with the build programme.
Who approves a kitchen extension in Holyhead?
Planning matters in Holyhead go to the council covering your address, and the work needs building control approval. We prepare and submit the applications for you.

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.

Should the kitchen be designed before the extension?
