How we approach skylight replacement in Croydon
Our skylight replacement service in Croydon covers replacing tired domes and failed glass with a modern rooflight. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Think of skylight replacement for older extensions due a modern rooflight.
Neighbouring towns include South Croydon (2 km) and Wallington (4 km). We offer a survey date when we reply to your enquiry.

Consents for skylight replacement in Croydon
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. 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.
