Conservation rooflights for Balham: the essentials
For Balham homes and buildings we offer conservation rooflights: slim, low-profile steel-look rooflights for period and listed roofs. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
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 conservation rooflights include period, listed and conservation-area roofs.
We work across Greater London, including Balham, and in neighbouring towns such as Clapham and Streatham. Access, parking and how the glass reaches the roof are all checked at the survey.
Options we can specify in Balham
- Steel or aluminium frames
- Flashings for slate or plain tile
- Blinds
- Central vertical glazing bar
- Toughened or laminated double glazing
- Suits slate and plain-tile roofs
- Optional central glazing bar
Things we check at survey
- Listed building consent is needed for listed buildings
- Projection above the roof line is limited — usually as flush as possible
Consents for conservation rooflights 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. 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.
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.
Read the planning permission guide before you commit to a design.

Questions about conservation rooflights in Balham

We cannot promise an outcome, but a slim conservation profile fitted low in the roof is the type many conservation officers ask for.
Can you copy an original rooflight?
Some makers produce bespoke sizes to match an existing opening. We can survey and quote.
Do I need consent for a conservation rooflight?
On a listed building you need listed building consent. In a conservation area, check with the council — many areas have Article 4 directions affecting roof alterations.
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.
Can you work alongside my builder in Balham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
