What are bespoke & shaped rooflights?
Across Northamptonshire, our bespoke & shaped rooflights work covers triangular, angled, curved and multi-pane rooflights made to measure. Survey first, fixed price second, fitting third.
Midlands housing is a mix of Victorian terraces, inter-war semis and newer estates, and rear kitchen extensions with flat rooflights are a common upgrade. Many Midlands semis have had a single-storey rear extension added, and a larger flat rooflight or lantern is often the change that makes it feel finished.

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. 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.

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 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.
Can bespoke units open?
Some can. Shaped glass is usually fixed, combined with a standard opening unit elsewhere.
Do you need my architect's drawings?
They help. We still survey on site, because built openings rarely match drawings exactly.
Do you offer bespoke & shaped rooflights across Northamptonshire?
Yes. We carry out bespoke & shaped rooflights across Northamptonshire, including Northampton, Corby, Kettering.
