How we approach bespoke & shaped rooflights in Northolt
For Northolt homes and buildings we offer bespoke & shaped rooflights: triangular, angled, curved and multi-pane rooflights made to measure. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. Think of bespoke & shaped rooflights for angled ceilings, corners and architect-designed extensions.
Neighbouring towns include Greenford (2 km) and Harrow (4 km). We offer a survey date when we reply to your enquiry.

Planning and building rules for Northolt
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. 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.
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.

Common questions
Can bespoke units open?
Some can. Shaped glass is usually fixed, combined with a standard opening unit elsewhere.
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.
Is the survey in Northolt free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Will I need planning permission in Northolt?
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.
