What do sliding rooflights in Wantage involve?
For Wantage homes and buildings we offer sliding rooflights: box rooflights whose glass lid slides back for walk-out roof access. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Think of sliding rooflights for staircases that rise to a roof terrace.
Jobs in Wantage 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
- Double or triple glazing
- Electric drive with safety edge
- Rain sensor
- Anthracite, black or RAL frames
- Integrated balustrade on some ranges
- Electric operation with safety stops
- Glazed box sides keep the headroom open
Things we check at survey
- Weight and point loads need a structural check
- Needs space on the roof for the lid to slide clear
Do you need permission in Wantage?
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.
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. 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.

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.
Is it lockable?
Yes. Units lock from inside and the drive holds the lid closed.
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.
How do I book a survey in Wantage?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Will I need planning permission in Wantage?
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.
