Common questions about
listed.
Yes, on any listed property. Even a like-for-like timber sash replacement requires consent. The penalty for unauthorised work can include a court order to reverse it.
Sometimes — on Grade I properties especially. We can install secondary glazing internally to provide thermal performance while preserving the historic glass.
We have direct working relationships across all 32 London boroughs. If a refusal looks likely we will tell you before you spend money on a hopeless application.
Free survey,
fixed quote.
Tell us about the property and we will come back within one working day with a window count, indicative price and the next available survey slot.
