Bespoke & shaped rooflights for Penrith: the essentials
We handle bespoke & shaped rooflights across Cumbria, including Penrith. In short: triangular, angled, curved and multi-pane rooflights made to measure. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
The North West gets more rain than most of England, so upstand height, membrane detailing and rain sensors on opening units are not optional extras. Think of bespoke & shaped rooflights for angled ceilings, corners and architect-designed extensions.
Penrith is around 28 km from Carlisle, and we survey and fit throughout that part of Cumbria, including the CA11 district.

Planning, building control and Penrith
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Do you need my architect's drawings?
They help. We still survey on site, because built openings rarely match drawings exactly.
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 I need to be at home for the survey in Penrith?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Will I need planning permission in Penrith?
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.
