Loft conversion skylights in Willesden: what is involved?
We handle loft conversion skylights across Greater London, including Willesden. 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. Typical uses for loft conversion skylights include attic bedrooms, offices and en-suites.
Willesden is around 8 km from central London, and we survey and fit throughout that part of Greater London, including the NW10 district.
What you can choose
- Balcony roof windows on some ranges
- Combination and stacked layouts
- Blackout and thermal blinds
- Conservation styles
- Centre-pivot or top-hung
- Set out on the rafters before plastering
- Escape-window sizing where required
Before you order: points to check
- Escape-window requirements apply to some loft rooms
- Front roof slopes can be restricted in conservation areas
Do you need permission in Willesden?
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.
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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about loft conversion skylights in Willesden
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.
Top-hung or centre-pivot in a loft?
Top-hung gives a clearer view and often suits escape use; centre-pivot is easier to clean and suits higher positions.
Do loft roof windows need to be escape windows?
Some loft rooms need an escape window, depending on the layout and the fire strategy for the conversion. Building control confirms the requirement.
Will I need planning permission in Willesden?
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.
Do I need to be at home for the survey in Willesden?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
