What do loft conversion skylights in Welwyn Garden City involve?
For Welwyn Garden City homes and buildings we offer loft conversion skylights: roof windows planned for loft rooms — light, headroom and escape. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Loft conversion skylights suit attic bedrooms, offices and en-suites.
Welwyn Garden City sits about 4 km from Hatfield and 9 km from Hertford, and we cover the whole AL8 postcode district and the roads in between.

Planning and building rules for Welwyn Garden City
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.
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.
Read the planning permission guide before you commit to a design.
