Skylights and rooflights in Keswick
From flat-roof extensions to period slate roofs, we fit the right rooflight for the building in Keswick — after a survey, with a fixed written price.
The North West gets more rain than most of England, so upstand height, membrane detailing and rain sensors on opening units are not optional extras.
Jobs in Keswick are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.

Planning and building rules in England
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. 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: Keswick
Will I need planning permission in Keswick?
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.
Can you work alongside my builder in Keswick?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do you fit skylights and rooflights in Keswick?
Yes. We survey and fit skylights and rooflights in Keswick and across Cumbria. Send your postcode and we will offer a survey date when we reply.
Do I need to be at home for the survey in Keswick?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
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.
