What does skylight installation in Towcester involve?
Thinking about skylight installation in Towcester? 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.
Bungalows are common across parts of the Midlands, and sun tunnels or roof windows are a quick way to brighten internal hallways. Skylight installation suits new extensions, new openings and fit-only jobs.
From Towcester to Northampton, Daventry and Milton Keynes, the same survey-first process applies: measure, specify, fix the price, then fit.

Consents for skylight installation 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. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about skylight installation in Towcester
How long does installation take?
Fitting into a prepared upstand takes about a day. A new opening in an existing roof, including making good, often takes two to three days.
Do you work with builders?
Yes — on new extensions we fit to the builder's programme once the upstand or roof is ready.
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.
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.
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.
