How we approach skylight replacement in Edmonton
Skylight replacement in Edmonton means replacing tired domes and failed glass with a modern rooflight. We cover the N18 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 Edmonton, as anywhere, skylight replacement is the usual choice for older extensions due a modern rooflight.
Edmonton sits about 3 km from Tottenham and 3 km from Enfield, and we cover the whole N18 postcode district and the roads in between.

Planning, building control and Edmonton
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. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
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.

Common questions
Can you replace only the misted glass?
Sometimes, if the frame is sound and the maker supplies replacement units. Often a complete new rooflight costs little more and performs better.
How long does a replacement take?
Usually a day for a standard rooflight on a sound upstand.
Will it mess up my ceiling?
We protect the room and make good the reveal. Minor decoration may be needed afterwards.
Do you offer skylight replacement in Edmonton?
Yes. We carry out skylight replacement in Edmonton and across Greater London. Send your postcode and we will offer a survey date when we reply.
Do I need to be at home for the survey in Edmonton?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
