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 Croydon?
In Croydon, a house renovation typically costs £1,150–£2,350 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 £103,500–£211,500. That range is adjusted for London, where domestic building work typically costs around 30% above the national average. Design, structural calculations and council fees are extra.

Do you need planning permission for a house renovation in Croydon?
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.
We check this for your address before design work starts, so there are no surprises later.
