What do sliding rooflights in Kingston upon Thames involve?
Thinking about sliding rooflights in Kingston upon Thames? The short answer: box rooflights whose glass lid slides back for walk-out roof access. The longer answer depends on your roof, which is why we survey before we 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. Typical uses for sliding rooflights include staircases that rise to a roof terrace.
Kingston upon Thames sits about 3 km from Twickenham and 3 km from Richmond, and we cover the whole KT1 postcode district and the roads in between.

Consents for sliding rooflights in Kingston upon Thames
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. 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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Sliding rooflights in Kingston upon Thames: questions
Does it need planning permission?
A box unit that projects above the roof plane can need planning permission, especially on the front of a house or in a conservation area. We check before you order.
Is a sliding rooflight better than an access hatch?
For daily use, usually yes — you walk out under open sky instead of climbing through a hinged hatch. A hatch costs less and suits occasional access.
What if it is raining?
Fitted with a rain sensor, an electric unit closes automatically. Most also have a manual override for power cuts.

Yes. We survey and fit sliding rooflights in Kingston upon Thames 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 Kingston upon Thames?
