Bespoke & shaped rooflights for Bow: the essentials
Our bespoke & shaped rooflights service in Bow covers triangular, angled, curved and multi-pane rooflights made to measure. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
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. Typical uses for bespoke & shaped rooflights include openings that standard sizes do not fit.
From Bow to Stratford, Hackney and Leytonstone, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning, building control and Bow
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.
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. 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.
