Sliding rooflights in Portslade: what is involved?
Sliding rooflights in Portslade means box rooflights whose glass lid slides back for walk-out roof access. We cover the BN41 district and the rest of East Sussex, with a survey before any price is fixed.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Sliding rooflights suit staircases that rise to a roof terrace.
Neighbouring towns include Hove (4 km) and Brighton (6 km). We offer a survey date when we reply to your enquiry.

Planning and building rules for Portslade
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.
Read the planning permission guide before you commit to a design.

Controls can be key-switched or placed out of reach. We will set the controls up to suit the household.
Is it lockable?
