Sliding rooflights in Walton-on-Thames: what is involved?
Sliding rooflights in Walton-on-Thames means box rooflights whose glass lid slides back for walk-out roof access. We cover the KT12 district and the rest of Surrey, with a survey before any price is fixed.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Typical uses for sliding rooflights include staircases that rise to a roof terrace.

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