Frameless structural rooflights in Bicester: what is involved?
Our frameless structural rooflights service in Bicester covers minimal glass rooflights with no visible frame from inside. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. In Bicester, as anywhere, frameless structural rooflights are the usual choice for rooms where you want sky without a visible frame.
Bicester is around 18 km from Oxford, and we survey and fit throughout that part of Oxfordshire, including the OX26 district.
Choices for your Bicester project
- Triple glazing
- Solar-control coatings
- Heated glass on some ranges
- Low-iron extra-clear glass
- Butt-jointed runs for long openings
- Long, slim or very large formats
- Can run along party walls and side returns
What to check first
- Large panes need lifting gear and access planning
- Tolerances are tight — the opening must be built square and to size
Planning, building control and Bicester
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.
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.

The process, step by step
- Tell us what you have. Send the OX26 postcode, a rough size and a couple of photos.
- Measure and check. A surveyor visits Bicester, measures and checks structure and access.
- Fixed quote. Product, work and price in writing — nothing is ordered until you agree.
- Fit and make good. We fit, seal, test and finish the reveal, then hand over the paperwork.

Common questions
Will I see the edge of the glass?
From inside, the reveal is finished up to the glass so the edge is hidden. From outside you will see the glass and its edge seal.
How is it lifted onto the roof?
Larger panes go up with a vacuum lifter, a hoist or a crane. We plan access at survey.
Can a frameless rooflight be walked on?
Only if it is specified as a walk-on unit. Most frameless rooflights are for light only.
Will I need planning permission in Bicester?
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 Bicester free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
