How we approach bespoke & shaped rooflights in Carshalton
We handle bespoke & shaped rooflights across Greater London, including Carshalton. 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.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Bespoke & shaped rooflights suit openings that standard sizes do not fit.
Carshalton is around 16 km from central London, and we survey and fit throughout that part of Greater London, including the SM5 district.

Planning and building rules for Carshalton
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.
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. 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.

Questions about bespoke & shaped rooflights in Carshalton
Will a shaped rooflight leak more?
Not if detailed properly — corners and junctions just need more care.
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.
Can any shape be made?
Most straight-edged shapes can be made in glass, within the manufacturer's size and angle limits. Curved glass is possible but specialist.
