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 Watford?
In Watford, a house renovation typically costs £950–£1,900 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 £85,500–£171,000. That range is adjusted for the East of England, where domestic building work typically costs around 6% above the national average. Design, structural calculations and council fees are extra.

Do you need planning permission for a house renovation in Watford?
Before anything is built in Watford, we confirm which approvals apply in England. In England internal renovation usually does not need planning permission unless the house is listed, when listed building consent covers internal work too. Notifiable work such as rewiring, structural changes, new windows and heating must meet building regulations.
Building regulations approval comes from the council’s building control service or a registered building control approver. The work is inspected at key stages, such as foundations, drainage and insulation, and a completion certificate is issued at the end.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.
What we handle
From survey to sign-off, the job normally involves:
- Plastering and boarding
- Joinery, doors and floors
- Condition survey and scope of works
- Building control for notifiable work
- Kitchens and bathrooms
- Structural repairs and damp treatment
How long does it take?
The build itself usually takes 8 to 20 weeks on site depending on scope. Design and approvals come first and typically take 6 to 12 weeks, depending on the approval route.
