Skylight replacement for Colchester: the essentials
We handle skylight replacement across Essex, including Colchester. In short: replacing tired domes and failed glass with a modern rooflight. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Coastal towns in the East of England see salty air, so we specify frame finishes and fixings with exposure in mind. Typical uses for skylight replacement include yellowed domes, misted glass and leaking roof windows.
Colchester is around 41 km from Southend-on-Sea, and we survey and fit throughout that part of Essex, including the CO1 district.

- Upstand and roof condition decide the scope
Planning, building control and Colchester
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.
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. 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.
Read the planning permission guide before you commit to a design.

Common questions
How long does a replacement take?
Usually a day for a standard rooflight on a sound upstand.
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.
Can I go bigger when replacing?
Possibly. Enlarging the opening means trimming joists, so we check the structure first.
Can you work alongside my builder in Colchester?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Will I need planning permission in Colchester?
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.
