How we approach loft conversion skylights in Cambridge
Thinking about loft conversion skylights in Cambridge? 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.
Flat, open landscape in much of the East means roofs take the wind, so upstand and seal details matter more than the brand of glass. Think of loft conversion skylights for attic bedrooms, offices and en-suites.
We work across Cambridgeshire, including Cambridge, and in neighbouring towns such as St Ives and Newmarket. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning, building control and Cambridge
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.
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. 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.
Read the planning permission guide before you commit to a design.

Questions about loft conversion skylights in Cambridge
Can I add blinds later?
Yes — most manufacturers make blinds for each window size.
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.
Can you work alongside my loft builder?
Yes — we set out and fit the windows to the builder's programme.
Do I need to be at home for the survey in Cambridge?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Is the survey in Cambridge free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
