Frameless structural rooflights in Wantage: what is involved?
Frameless structural rooflights in Wantage means minimal glass rooflights with no visible frame from inside. We cover the OX12 district and the rest of Oxfordshire, with a survey before any price is fixed.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Frameless structural rooflights suit architect-led extensions and long slots of light over islands or along party walls.
Wantage is around 22 km from Oxford, and we survey and fit throughout that part of Oxfordshire, including the OX12 district.

Planning and building rules for 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.
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Can a frameless rooflight be walked on?
Only if it is specified as a walk-on unit. Most frameless rooflights are for light only.
Is frameless glass as strong as a framed rooflight?
Yes — it is structural glass designed for the job. The support is hidden rather than missing.
Does it cost more?
Usually, because the glass is larger and heavier and the finish needs tighter tolerances. The price table shows typical ranges.
Do I need to be at home for the survey in Wantage?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Wantage?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
