Insulation Tips for London
London Victorian and Edwardian terraces have solid walls — EWI or internal wall insulation are the only options for wall upgrades.
London labour rates run 20–30% above national average — get at least three quotes from TrustMark-registered installers.
Check if your property is in a conservation area before installing EWI — planning permission may be needed.
