Skylight installation in Southport: what is involved?
Skylight installation in Southport means survey, supply and fit — new openings, extensions and fit-only work. We cover the PR8 district and the rest of Merseyside, with a survey before any price is fixed.
Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed. Typical uses for skylight installation include new extensions, new openings and fit-only jobs.
Southport is around 26 km from Liverpool, and we survey and fit throughout that part of Merseyside, including the PR8 district.

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

Common questions
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 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 to be at home for the survey in Southport?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Southport?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
