How we approach skylight replacement in Heswall
For Heswall homes and buildings we offer skylight replacement: replacing tired domes and failed glass with a modern rooflight. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed. Typical uses for skylight replacement include yellowed domes, misted glass and leaking roof windows.
We work across Merseyside, including Heswall, and in neighbouring towns such as Bebington and Birkenhead. Access, parking and how the glass reaches the roof are all checked at the survey.

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