How we approach roof lanterns in Acton
Our roof lanterns service in Acton covers hipped glass lanterns that lift the ceiling of orangeries and extensions. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
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. In Acton, as anywhere, roof lanterns are the usual choice for rooms that need height as well as light.
Acton is around 10 km from central London, and we survey and fit throughout that part of Greater London, including the W3 district.

Planning, building control and Acton
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. 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.

Roof lanterns in Acton: questions
Do roof lanterns get hot?
They can in summer if clear glass is used on a south-facing roof. Solar-control glass and an opening vent make a big difference.
How big can a lantern be?
Aluminium systems go to around three by six metres in standard ranges; larger sizes are made to order.
Do they leak?
Modern lanterns are sealed systems. Leaks usually trace back to the kerb or roof membrane detail, which we form and check ourselves.
Do you fit roof lanterns in Acton?
Yes. We survey and fit roof lanterns in Acton and across Greater London. Send your postcode and we will offer a survey date when we reply.
Do I need to be at home for the survey in Acton?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
