Bespoke & shaped rooflights for Chesham: the essentials
Thinking about bespoke & shaped rooflights in Chesham? The short answer: triangular, angled, curved and multi-pane rooflights made to measure. The longer answer depends on your roof, which is why we survey before we 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.
Chesham is around 39 km from Milton Keynes, and we survey and fit throughout that part of Buckinghamshire, including the HP5 district.

- Triangular and trapezoid panes

Planning and building rules for Chesham
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.
