What we fit in Balham
From flat-roof extensions to period slate roofs, we fit the right rooflight for the building in Balham — after a survey, with a fixed written price.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep.
Balham is around 7 km from central London, and we survey and fit throughout that part of Greater London, including the SW12 district.

Planning and building rules in England
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. 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. 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.

Skylight questions: Balham
Will I need planning permission in 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.
Is the survey in Balham free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
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.
How do I book a survey in Balham?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can I cancel?
Made-to-measure products are excluded from the statutory 14-day cancellation right, but you can cancel without charge until we place the order with the manufacturer. Our terms explain the rest.
Can a skylight be fitted into an existing flat roof?
Yes. We form the opening, trim joists, build an insulated upstand, re-waterproof and make good the ceiling.
