What are loft conversion skylights?
Loft conversion skylights in Berkshire means roof windows planned for loft rooms — light, headroom and escape. Every quote follows a survey of the roof and the room below.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens.

Planning and building rules in England
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. 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.
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.

How the job runs
- Tell us about the roof. Send the postcode, rough sizes and a photo or two through the form, WhatsApp or the guide-price tool.
- Free survey. For new installations a surveyor measures the opening, checks the roof build-up and talks through glass and options.
- Fixed written quote. You get the product, the work and the price in writing. Nothing is ordered or paid for until you agree.
- Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.

Common questions
Can you work alongside my loft builder?
Yes — we set out and fit the windows to the builder's programme.
Can I add blinds later?
Yes — most manufacturers make blinds for each window size.
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 I need to be at home for the survey in Berkshire?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
