What is a house renovation?
A house renovation brings an older or tired home up to date. It can include rewiring, a new heating system, replastering, new floors, windows, kitchens and bathrooms, and changes to the layout. A full renovation is often combined with an extension or loft conversion.
How much does a house renovation cost in Powys?
In Powys, a house renovation typically costs £850–£1,650 per m² for a medium to full renovation, including VAT at 20% (5% may apply to homes empty for two years or more). For a typical 90 m² project that is roughly £76,500–£148,500. Building costs in Wales run about 8% below the UK average, and the figures for Powys are adjusted to reflect that.

Do you need planning permission for a house renovation in Powys?
The approval route for Powys is set by planning law in Wales. In Wales internal renovation usually does not need planning permission unless the house is listed. Notifiable work must meet building regulations.
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.
