Skylight replacement in Brighton: what is involved?
For Brighton homes and buildings we offer skylight replacement: replacing tired domes and failed glass with a modern rooflight. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Skylight replacement suits older extensions due a modern rooflight.
We cover all of Brighton and the BN1 district, and nearby Hove and Portslade.
Options we can specify in Brighton
- Like-for-like size replacement
- Fixed to electric opening
- Misted glass unit replacement only
- Roof window replacement in pitched roofs
- Upstand rebuild and insulation
- Clearer view and more light
- Usually done in a day
What to check first
- A replacement is a chance to meet current thermal standards
- Old glass and domes are disposed of responsibly
Planning and building rules for Brighton
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. 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.
