What are bespoke & shaped rooflights?
Across Devon, our bespoke & shaped rooflights work covers triangular, angled, curved and multi-pane rooflights made to measure. Survey first, fixed price second, fitting third.
Stone cottages, slate roofs and conservation areas are common in the South West, and conservation-profile rooflights keep the roofline quiet. 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
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. 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.

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.
Do you need my architect's drawings?
They help. We still survey on site, because built openings rarely match drawings exactly.
Can I cancel a bespoke order?
Made-to-measure goods are excluded from the statutory 14-day cancellation right. As a goodwill gesture you can cancel without charge until we place the order with the manufacturer, and we tell you in writing when that happens.
Why does bespoke take longer?
Each unit is drawn, checked and manufactured to order.
Will I need planning permission in Devon?
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.
