Skylight installation for Hythe: the essentials
We handle skylight installation across Hampshire, including Hythe. In short: survey, supply and fit — new openings, extensions and fit-only work. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. In Hythe, as anywhere, skylight installation is the usual choice for new extensions, new openings and fit-only jobs.
Hythe sits about 5 km from Southampton and 9 km from Totton, and we cover the whole SO45 postcode district and the roads in between.

Before you order: points to check

Planning, building control and Hythe
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.
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.

Questions about skylight installation in Hythe
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.
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.
Is the survey free?
Yes, for new installations. Repair visits are charged.
Will I need planning permission in Hythe?
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.
Do I need to be at home for the survey in Hythe?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
