Conservation rooflights in Northampton: what is involved?
Conservation rooflights in Northampton means slim, low-profile steel-look rooflights for period and listed roofs. We cover the NN1 district and the rest of Northamptonshire, with a survey before any price is fixed.
Many Midlands semis have had a single-storey rear extension added, and a larger flat rooflight or lantern is often the change that makes it feel finished. Typical uses for conservation rooflights include period, listed and conservation-area roofs.
We cover all of Northampton and the NN1 district, and nearby Wellingborough and Towcester.

What to check first

- Projection above the roof line is limited — usually as flush as possible
Consents for conservation rooflights in Northampton
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.
