Frameless structural rooflights in Bath: what is involved?
Our frameless structural rooflights service in Bath 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.
Holiday lets and second homes across the South West often want roof windows with blinds and remote opening for when the house is empty. Think of frameless structural rooflights for architect-led extensions and long slots of light over islands or along party walls.
We cover all of Bath and the BA1 district, and nearby Trowbridge and Kingswood.

- Heated glass on some ranges

What to check first
- Large panes need lifting gear and access planning
- Tolerances are tight — the opening must be built square and to size
Do you need permission in Bath?
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
See our building regulations guide for U-values, glazing limits and self-certification.

- Free site visit. For new installs we survey free, measure and confirm the roof detail.
- Agree the quote. You approve the specification and price before anything is ordered.
- 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.
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.
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.
How do I book a survey in Bath?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Bath?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
