Rooflights for Gerrards Cross homes and buildings
We survey, supply and fit skylights and rooflights in Gerrards Cross and the SL9 district — flat rooflights, roof lanterns, roof windows, walk-on glass, sun tunnels and commercial rooflights.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice.
From Gerrards Cross to Chalfont St Peter, Uxbridge and Rickmansworth, the same survey-first process applies: measure, specify, fix the price, then fit.

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: Gerrards Cross
Is the survey in Gerrards Cross free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Can you work alongside my builder in Gerrards Cross?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Gerrards Cross?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Will I need planning permission in Gerrards Cross?
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.
Will a rooflight make my room too hot?
It can on a south-facing roof with clear glass. Solar-control glass, an opening unit and a blind keep the room comfortable.
Fixed or opening?
Opening units suit kitchens, bathrooms and bedrooms; fixed units are simpler and cheaper where the room already ventilates well.
