What are bespoke & shaped rooflights?
Bespoke & shaped rooflights in Derbyshire means triangular, angled, curved and multi-pane rooflights made to measure. Every quote follows a survey of the roof and the room below.
Industrial and commercial units around Midlands towns often still have their original rooflight sheets, which are due for replacement. 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.

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.
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.

How the job runs

- 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.
Why does bespoke take longer?
Each unit is drawn, checked and manufactured to order.
Do you need my architect's drawings?
They help. We still survey on site, because built openings rarely match drawings exactly.
Can bespoke units open?
Some can. Shaped glass is usually fixed, combined with a standard opening unit elsewhere.
Will I need planning permission in Derbyshire?
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.
