Bespoke & shaped rooflights in Isleworth: what is involved?
Bespoke & shaped rooflights in Isleworth means triangular, angled, curved and multi-pane rooflights made to measure. We cover the TW7 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. Think of bespoke & shaped rooflights for openings that standard sizes do not fit.
We work across Greater London, including Isleworth, and in neighbouring towns such as Hounslow and Richmond. Access, parking and how the glass reaches the roof are all checked at the survey.

Consents for bespoke & shaped rooflights in Isleworth
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.
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. 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.

Common questions
Do you need my architect's drawings?
They help. We still survey on site, because built openings rarely match drawings exactly.
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.

Yes. We carry out bespoke & shaped rooflights in Isleworth and across Greater London. Send your postcode and we will offer a survey date when we reply.
Will I need planning permission in Isleworth?
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.
