Bespoke & shaped rooflights for Mitcham: the essentials
For Mitcham 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.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. Bespoke & shaped rooflights suit angled ceilings, corners and architect-designed extensions.
We work across Greater London, including Mitcham, and in neighbouring towns such as Morden and Wimbledon. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning, building control and Mitcham
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. 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.
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. 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
Can bespoke units open?
Some can. Shaped glass is usually fixed, combined with a standard opening unit elsewhere.
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.
Will I need planning permission in Mitcham?
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.
Can you work alongside my builder in Mitcham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
