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