How we approach loft conversion skylights in Blackheath
Thinking about loft conversion skylights in Blackheath? The short answer: roof windows planned for loft rooms — light, headroom and escape. The longer answer depends on your roof, which is why we survey before we price.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Think of loft conversion skylights for loft conversions and rooms in the roof.
Jobs in Blackheath 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
- Centre-pivot or top-hung
- Combination and stacked layouts
- Blackout and thermal blinds
- Electric or solar opening
- Balcony roof windows on some ranges
- Blinds and blackout for bedrooms
- Set out on the rafters before plastering
What to check first
- Escape-window requirements apply to some loft rooms
- Rafter spacing affects window widths
Do you need permission in Blackheath?
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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.

Top-hung gives a clearer view and often suits escape use; centre-pivot is easier to clean and suits higher positions.
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.
Can you work alongside my loft builder?
Yes — we set out and fit the windows to the builder's programme.
