Loft conversion skylights in Eltham: what is involved?
Loft conversion skylights in Eltham means roof windows planned for loft rooms — light, headroom and escape. We cover the SE9 district and the rest of Greater London, with a survey before any price is fixed.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep. In Eltham, as anywhere, loft conversion skylights are the usual choice for loft conversions and rooms in the roof.
We work across Greater London, including Eltham, and in neighbouring towns such as Blackheath and Welling. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning and building rules for 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. 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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about loft conversion skylights in Eltham
Will the loft be cold near the windows?
Correctly fitted insulation collars and linings keep the window surround warm and reduce condensation.
Can you work alongside my loft builder?
Yes — we set out and fit the windows to the builder's programme.
How many roof windows does a loft room need?
Enough to give good light — a common rule of thumb is glazing equal to roughly a tenth to a fifth of the floor area, adjusted for orientation and use. We advise at survey.
Do I need to be at home for the survey in Eltham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Eltham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
