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 Sevenoaks?
In Sevenoaks, a house renovation typically costs £1,000–£2,000 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 £90,000–£180,000. We start from a UK-wide guide and adjust it for the South East, where labour and materials are typically about 12% above average. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| Smaller project (63 m²) | £63,000–£126,000 |
| Typical project (90 m²) | £90,000–£180,000 |
| Larger project (126 m²) | £126,000–£252,000 |
| Rate per m² | £1,000–£2,000 |
The biggest cost drivers are:
- Whether you live in during the work
- Windows and doors
- Extent of rewiring and replumbing
- Structural and damp repairs
Use the guide price tool to see how size and specification change the figure, then ask for a written, itemised quote.
Do you need planning permission for a house renovation in Sevenoaks?
Whether you need planning permission depends on your house and its location 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.
Where work involves a shared wall, building on the boundary, or digging foundations within 3 metres of a neighbour’s building and deeper than its foundations (or within 6 metres for deeper work), the Party Wall etc. Act 1996 applies and notices must be served before work starts.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.
