How we approach skylight installation in Retford
Thinking about skylight installation in Retford? 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.
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. Typical uses for skylight installation include builders' projects and retrofits into finished roofs.
From Retford to Worksop, Gainsborough and Doncaster, the same survey-first process applies: measure, specify, fix the price, then fit.

Do you need permission in Retford?
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. 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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.

Common questions
Do you work with builders?
Yes — on new extensions we fit to the builder's programme once the upstand or roof is ready.
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 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 I need to be at home for the survey in Retford?
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 Retford?
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.
