Skylight installation for Hammersmith: the essentials
For Hammersmith homes and buildings we offer skylight installation: survey, supply and fit — new openings, extensions and fit-only work. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. Think of skylight installation for builders' projects and retrofits into finished roofs.
Hammersmith sits about 1 km from Shepherds Bush and 2 km from Chiswick, and we cover the whole W6 postcode district and the roads in between.

Planning and building rules for Hammersmith
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
See our building regulations guide for U-values, glazing limits and self-certification.

We tell you which route applies — building control approval, a building warrant in Scotland, or in England and Wales self-certification by a registered competent person — and supply the product data.

For new openings that cut joists or rafters, a structural check is sensible and building control may ask for calculations.

Yes — on new extensions we fit to the builder's programme once the upstand or roof is ready.
