How we approach skylight replacement in Bognor Regis
Our skylight replacement service in Bognor Regis 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.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Typical uses for skylight replacement include yellowed domes, misted glass and leaking roof windows.
Bognor Regis sits about 9 km from Chichester and 10 km from Littlehampton, and we cover the whole PO21 postcode district and the roads in between.
What you can choose
- Dome to flat glass upgrade
- Roof window replacement in pitched roofs

Before you order: points to check
- Enlarging the opening changes the structure and may need approval
- A replacement is a chance to meet current thermal standards
Planning, building control and Bognor Regis
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. 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.

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.
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.
How long does a replacement take?
Usually a day for a standard rooflight on a sound upstand.
