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 Kent?
In Kent, 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. The guide for Kent reflects typical costs in the South East, roughly 12% above the UK-wide figure. 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:
- Extent of rewiring and replumbing
- Whether you live in during the work
- Finishes
- Structural and damp repairs
Your exact price depends on the survey and drawings. The guide price tool gives a quick range in the meantime.
Do you need planning permission for a house renovation in Kent?
Approvals for a house renovation in Kent follow the rules for 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.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.
