Skylight replacement for South Croydon: the essentials
Skylight replacement in South Croydon means replacing tired domes and failed glass with a modern rooflight. We cover the CR2 district and the rest of Greater London, with a survey before any price is fixed.
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. In South Croydon, as anywhere, skylight replacement is the usual choice for older extensions due a modern rooflight.
From South Croydon to Croydon, Purley and Wallington, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning, building control and South 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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about skylight replacement in South Croydon
How long does a replacement take?
Usually a day for a standard rooflight on a sound upstand.
Can I go bigger when replacing?
Possibly. Enlarging the opening means trimming joists, so we check the structure first.
What do you do with the old unit?
We remove it from site and recycle what can be recycled.
Can you work alongside my builder in South Croydon?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in South Croydon?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
