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.

Do you need planning permission for a house renovation in Walthamstow?
The approval route for Walthamstow is set by planning law 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.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.
