Conservation rooflights for Ely: the essentials
For Ely homes and buildings we offer conservation rooflights: slim, low-profile steel-look rooflights for period and listed roofs. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Flat, open landscape in much of the East means roofs take the wind, so upstand and seal details matter more than the brand of glass. Think of conservation rooflights for period, listed and conservation-area roofs.
Jobs in Ely are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
What you can choose
- Toughened or laminated double glazing
- Flashings for slate or plain tile
- Steel or aluminium frames
- Central vertical glazing bar
- Blinds
- Often preferred by conservation officers
- Suits slate and plain-tile roofs
What to check first
- Projection above the roof line is limited — usually as flush as possible
- Lead or matching flashings may be required
Consents for conservation rooflights in Ely
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. 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.
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.
See our building regulations guide for U-values, glazing limits and self-certification.
