What is skylight replacement?
Across Gloucestershire, our skylight replacement work covers replacing tired domes and failed glass with a modern rooflight. Survey first, fixed price second, fitting third.
Many South West towns mix Georgian and Victorian terraces with modern estates, so the right product differs street by street. Stone cottages, slate roofs and conservation areas are common in the South West, and conservation-profile rooflights keep the roofline quiet.

Planning and building rules in England
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.
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.

How the job runs
- Tell us about the roof. Send the postcode, rough sizes and a photo or two through the form, WhatsApp or the guide-price tool.
- Free survey. For new installations a surveyor measures the opening, checks the roof build-up and talks through glass and options.
- Fixed written quote. You get the product, the work and the price in writing. Nothing is ordered or paid for until you agree.
- Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.

Common questions
How long does a replacement take?
Usually a day for a standard rooflight on a sound upstand.
What do you do with the old unit?
We remove it from site and recycle what can be recycled.
Do I need building regulations approval to replace a rooflight?
Replacements in existing homes generally need to meet current thermal standards and may need notification or approval. We advise on the route for your job.
Will it mess up my ceiling?
We protect the room and make good the reveal. Minor decoration may be needed afterwards.
Do I need to be at home for the survey in Gloucestershire?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
