Commercial & industrial rooflights for Witney: the essentials
Our commercial & industrial rooflights service in Witney covers rooflights for warehouses, schools, offices and retail units. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Commercial & industrial rooflights suit industrial roofs with tired or fragile rooflight sheets.
Witney is around 16 km from Oxford, and we survey and fit throughout that part of Oxfordshire, including the OX28 district.
What you can choose
- GRP or polycarbonate in-plane rooflight sheets
- Continuous barrel-vault rooflights
- Smoke and natural ventilation vents
- Modular glass rooflights
- Mesh or grilles under fragile areas
- Replacement of discoloured or fragile sheets
- Daylight that reduces daytime lighting
Before you order: points to check
- Fire performance of rooflight materials matters near boundaries
- Non-fragility classification should be confirmed for new products
Building control and safety duties in Witney
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. We confirm the route for your building before ordering.
For buildings other than dwellings, Approved Document L Volume 2 sets limiting U-values of 2.2 W/m²K for rooflights and 3.0 W/m²K for roof ventilators, including smoke vents. Fragile-roof safety and access are planned before work starts.
Read the planning permission guide before you commit to a design.

Commercial & industrial rooflights in Witney: questions
Are old rooflights a safety risk?
Older plastic rooflight sheets can become brittle. Anyone working on the roof must treat them as fragile unless proven otherwise.
Do you work out of hours?
For occupied buildings we can plan phased or out-of-hours working where access allows.
Can you quote from drawings?
Yes, with a site survey to confirm.
Can you work alongside my builder in Witney?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Witney?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
