Sliding rooflights in Eastbourne: what is involved?
We handle sliding rooflights across East Sussex, including Eastbourne. In short: box rooflights whose glass lid slides back for walk-out roof access. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
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 walk-out access where a hatch would feel cramped.
Jobs in Eastbourne are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Specification options
- Box (glazed sides) or flat sliding lid
- Anthracite, black or RAL frames
- Integrated balustrade on some ranges
- Rain sensor
- Double or triple glazing
- Full-width, walk-out access to a roof terrace
- Glazed box sides keep the headroom open
What to check first
- Needs space on the roof for the lid to slide clear
- Weight and point loads need a structural check
Do you need permission in Eastbourne?
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
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.
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 Eastbourne?
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.
Is the survey in Eastbourne free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
