What does skylight replacement in Eltham involve?
For Eltham 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 London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. In Eltham, as anywhere, skylight replacement is the usual choice for older extensions due a modern rooflight.
Neighbouring towns include Blackheath (3 km) and Welling (4 km). We offer a survey date when we reply to your enquiry.
Specification options
- Fixed to electric opening
- Like-for-like size replacement
- Misted glass unit replacement only
- Upstand rebuild and insulation
- Roof window replacement in pitched roofs
- Better thermal performance
- Often reuses the existing opening
Things we check at survey
- Upstand and roof condition decide the scope
- Enlarging the opening changes the structure and may need approval
Consents for skylight replacement in Eltham
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. 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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.
Read the planning permission guide before you commit to a design.
