Bespoke & shaped rooflights for Amersham: the essentials
We handle bespoke & shaped rooflights across Buckinghamshire, including Amersham. 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.
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 angled ceilings, corners and architect-designed extensions.
From Amersham to Chesham, Chalfont St Peter and Gerrards Cross, the same survey-first process applies: measure, specify, fix the price, then fit.

Do you need permission in Amersham?
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. 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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Bespoke & shaped rooflights in Amersham: questions
Can I cancel a bespoke order?
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.
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 Amersham?
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 Amersham?
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.
