Loft conversion skylights in Greenwich: what is involved?
We handle loft conversion skylights across Greater London, including Greenwich. In short: roof windows planned for loft rooms — light, headroom and escape. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. In Greenwich, as anywhere, loft conversion skylights are the usual choice for attic bedrooms, offices and en-suites.
Greenwich sits about 2 km from Blackheath and 3 km from Lewisham, and we cover the whole SE10 postcode district and the roads in between.
What you can choose
- Balcony roof windows on some ranges
- Centre-pivot or top-hung
- Electric or solar opening
- Combination and stacked layouts
- Blackout and thermal blinds
- Escape-window sizing where required
- Set out on the rafters before plastering
What to check first
- Escape-window requirements apply to some loft rooms
- Rafter spacing affects window widths
Planning, building control and Greenwich
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.
