How we approach bespoke & shaped rooflights in Balham
Bespoke & shaped rooflights in Balham means triangular, angled, curved and multi-pane rooflights made to measure. We cover the SW12 district and the rest of Greater London, with a survey before any price is fixed.
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. Typical uses for bespoke & shaped rooflights include openings that standard sizes do not fit.
From Balham to Clapham, Streatham and Brixton, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning and building rules for Balham
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. 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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about bespoke & shaped rooflights in Balham
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.
Why does bespoke take longer?
Each unit is drawn, checked and manufactured to order.
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.
Will I need planning permission in Balham?
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.
Do I need to be at home for the survey in Balham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
