Sliding rooflights in Greenford: what is involved?
Sliding rooflights in Greenford means box rooflights whose glass lid slides back for walk-out roof access. We cover the UB6 district and the rest of Greater London, with a survey before any price is fixed.
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. Typical uses for sliding rooflights include walk-out access where a hatch would feel cramped.
From Greenford to Northolt, Southall and Ealing, the same survey-first process applies: measure, specify, fix the price, then fit.

Consents for sliding rooflights in Greenford
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. 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.
