How we approach skylight installation in Weymouth
Thinking about skylight installation in Weymouth? The short answer: survey, supply and fit — new openings, extensions and fit-only work. The longer answer depends on your roof, which is why we survey before we price.
Holiday lets and second homes across the South West often want roof windows with blinds and remote opening for when the house is empty. Skylight installation suits builders' projects and retrofits into finished roofs.
Neighbouring towns include Dorchester (12 km) and Bridport (25 km). We offer a survey date when we reply to your enquiry.

Planning, building control and Weymouth
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.
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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Skylight installation in Weymouth: questions
Is the survey free?
Yes, for new installations. Repair visits are charged.
Do I need a structural engineer?
For new openings that cut joists or rafters, a structural check is sensible and building control may ask for calculations.
Do you fit rooflights bought elsewhere?
Yes. We check the product and the opening first, and our workmanship terms cover the fitting rather than the product.
How do I book a survey in Weymouth?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Do I need to be at home for the survey in Weymouth?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
