Loft conversion skylights in Crowthorne: what is involved?
For Crowthorne homes and buildings we offer loft conversion skylights: roof windows planned for loft rooms — light, headroom and escape. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Think of loft conversion skylights for loft conversions and rooms in the roof.
Crowthorne is around 16 km from Reading, and we survey and fit throughout that part of Berkshire, including the RG45 district.
Specification options
- Combination and stacked layouts
- Blackout and thermal blinds
- Conservation styles
- Balcony roof windows on some ranges
- Electric or solar opening
- Set out on the rafters before plastering
- Light planned around the room layout
What to check first
- Escape-window requirements apply to some loft rooms
- Rafter spacing affects window widths
Do you need permission in Crowthorne?
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. 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.
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 Crowthorne
Will the loft be cold near the windows?
Correctly fitted insulation collars and linings keep the window surround warm and reduce condensation.
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.
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.
