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 Birmingham?
In Birmingham, a house renovation typically costs £850–£1,750 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–£157,500. Building costs in the West Midlands are close to the UK average, so the figures for Birmingham are close to our national guide.

Do you need planning permission for a house renovation in Birmingham?
Here is how the rules work for a house renovation 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.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.

- Structural repairs and damp treatment
- Building control for notifiable work

The build itself usually takes 8 to 20 weeks on site depending on scope. Before that, surveys, drawings and approvals usually take 6 to 12 weeks, longer if the council asks for changes.
