How we approach sliding rooflights in Richmond
For Richmond homes and buildings we offer sliding rooflights: box rooflights whose glass lid slides back for walk-out roof access. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. Think of sliding rooflights for walk-out access where a hatch would feel cramped.
From Richmond to Twickenham, Isleworth and Kingston upon Thames, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning and building rules for Richmond
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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Is it lockable?
Yes. Units lock from inside and the drive holds the lid closed.
What if it is raining?
Fitted with a rain sensor, an electric unit closes automatically. Most also have a manual override for power cuts.
How heavy is it?
Box sliders weigh hundreds of kilograms, so delivery may need a crane or lifting gear, and the structure must be checked.
Will I need planning permission in Richmond?
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.
