How we approach sun tunnels & tubular skylights in New Malden
Thinking about sun tunnels & tubular skylights in New Malden? The short answer: light pipes that bring daylight to halls and bathrooms with no window. The longer answer depends on your roof, which is why we survey before we 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. Think of sun tunnels & tubular skylights for windowless hallways, landings and bathrooms.
We work across Greater London, including New Malden, and in neighbouring towns such as Surbiton and Kingston upon Thames. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning, building control and New Malden
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. 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.
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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
