Conservation rooflights in Washington: what is involved?
Conservation rooflights in Washington means slim, low-profile steel-look rooflights for period and listed roofs. We cover the NE37 district and the rest of Tyne and Wear, with a survey before any price is fixed.
North East terraces and colliery-town housing often have rear offshoots where a rooflight brightens a narrow kitchen. Conservation rooflights suit period, listed and conservation-area roofs.
From Washington to Chester-le-Street, Felling and Houghton-le-Spring, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Washington
- Central vertical glazing bar
- Steel or aluminium frames
- Blinds
- Manual or electric opening
- Toughened or laminated double glazing

- Steel or aluminium frame in black or grey
Things we check at survey
- Lead or matching flashings may be required
- Projection above the roof line is limited — usually as flush as possible
Consents for conservation rooflights in Washington
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.
