Bespoke & shaped rooflights for Swanley: the essentials
Our bespoke & shaped rooflights service in Swanley covers triangular, angled, curved and multi-pane rooflights made to measure. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Typical uses for bespoke & shaped rooflights include openings that standard sizes do not fit.

Planning, building control and Swanley
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
Will a shaped rooflight leak more?
Not if detailed properly — corners and junctions just need more care.

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.
Can bespoke units open?
Some can. Shaped glass is usually fixed, combined with a standard opening unit elsewhere.
