Sliding rooflights in Hackney: what is involved?
Sliding rooflights in Hackney means box rooflights whose glass lid slides back for walk-out roof access. We cover the E8 district and the rest of Greater London, with a survey before any price is fixed.
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.
Hackney sits about 3 km from Bow and 3 km from Stratford, and we cover the whole E8 postcode district and the roads in between.

Do you need permission in Hackney?
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
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. 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 Hackney: questions
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.
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.
Will I need planning permission in Hackney?
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.
Do I need to be at home for the survey in Hackney?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
