What do bespoke & shaped rooflights involve?
Across Somerset, our bespoke & shaped rooflights work covers triangular, angled, curved and multi-pane rooflights made to measure. Survey first, fixed price second, fitting third.
Holiday lets and second homes across the South West often want roof windows with blinds and remote opening for when the house is empty. Many South West towns mix Georgian and Victorian terraces with modern estates, so the right product differs street by street.

Planning and building rules in England
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. 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
Will a shaped rooflight leak more?
Not if detailed properly — corners and junctions just need more care.
Can bespoke units open?
Some can. Shaped glass is usually fixed, combined with a standard opening unit elsewhere.
Can any shape be made?
Most straight-edged shapes can be made in glass, within the manufacturer's size and angle limits. Curved glass is possible but specialist.
Do you need my architect's drawings?
They help. We still survey on site, because built openings rarely match drawings exactly.
Do I need to be at home for the survey in Somerset?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
