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 Upminster?
In Upminster, 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. We start from a UK-wide guide and adjust it for London, where labour and materials are typically about 30% above average. Design, structural calculations and council fees are extra.

Do you need planning permission for a house renovation in Upminster?
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.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.
