Conservation rooflights for Rochester: the essentials
Conservation rooflights in Rochester means slim, low-profile steel-look rooflights for period and listed roofs. We cover the ME1 district and the rest of Kent, with a survey before any price is fixed.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. In Rochester, as anywhere, conservation rooflights are the usual choice for period, listed and conservation-area roofs.
Rochester sits about 2 km from Chatham and 2 km from Strood, and we cover the whole ME1 postcode district and the roads in between.

Do you need permission in Rochester?
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
Read the planning permission guide before you commit to a design.
