What we fit in Towcester
We survey, supply and fit skylights and rooflights in Towcester and the NN12 district — flat rooflights, roof lanterns, roof windows, walk-on glass, sun tunnels and commercial rooflights.
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.
Towcester is around 15 km from Northampton, and we survey and fit throughout that part of Northamptonshire, including the NN12 district.

Planning and building rules in England
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. 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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.

Skylight questions: Towcester
Is the survey in Towcester free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Will I need planning permission in Towcester?
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.
Do I need to be at home for the survey in Towcester?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Towcester?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Can a skylight be fitted into an existing flat roof?
Yes. We form the opening, trim joists, build an insulated upstand, re-waterproof and make good the ceiling.
Fixed or opening?
Opening units suit kitchens, bathrooms and bedrooms; fixed units are simpler and cheaper where the room already ventilates well.
