Skylight installation for Cheshunt: the essentials
Skylight installation in Cheshunt means survey, supply and fit — new openings, extensions and fit-only work. We cover the EN8 district and the rest of Hertfordshire, with a survey before any price is fixed.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Think of skylight installation for builders' projects and retrofits into finished roofs.
Neighbouring towns include Waltham Abbey (2 km) and Enfield (7 km). We offer a survey date when we reply to your enquiry.

Planning, building control and Cheshunt
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. 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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.

Common questions
Do you work with builders?
Yes — on new extensions we fit to the builder's programme once the upstand or roof is ready.
Do you fit rooflights bought elsewhere?
Yes. We check the product and the opening first, and our workmanship terms cover the fitting rather than the product.
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.
Is the survey in Cheshunt free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Will I need planning permission in Cheshunt?
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof.
