How we approach conservation rooflights in Portslade
Conservation rooflights in Portslade means slim, low-profile steel-look rooflights for period and listed roofs. We cover the BN41 district and the rest of East Sussex, with a survey before any price is fixed.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Typical uses for conservation rooflights include slate and plain-tile roofs where a quiet roofline matters.
From Portslade to Hove, Brighton and Worthing, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Portslade
- Steel or aluminium frames
- Toughened or laminated double glazing
- Central vertical glazing bar
- Flashings for slate or plain tile
- Blinds
- Optional central glazing bar
- Often preferred by conservation officers
What to check first
- Lead or matching flashings may be required
- Projection above the roof line is limited — usually as flush as possible
Do you need permission in Portslade?
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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.
