About internal windows and borrowed light
An internal window is a fixed glazed panel set into an internal wall to borrow daylight from a bright room for a dark one — an inner hallway, a landing, a windowless bathroom or a box room. A glazed fanlight over a door does the same job. Full details on internal windows and borrowed light.
Internal windows and borrowed light for Bristol properties
Much of what we fit in Bristol goes into Georgian terraces in Clifton, Victorian houses in Bishopston and Totterdown, and harbourside apartments. The survey is where we spot the things that change a price — a sloping floor, a hidden pipe, a wall that needs a lintel — so there are no surprises later. We also work for local businesses, including offices around Temple Quarter and the city centre, plus creative studios in Stokes Croft.
Cost and lead time in Bristol
Guide pricing for internal windows and borrowed light in Bristol is £450–£800 per m² plus VAT, including fitting — small jobs start from about £450. Whether you're in Bristol or a village outside it, our surveyors cover BS postcodes — expect typically 3–5 weeks from survey.
Building Regulations and safety
Glass within 800mm of the floor must be safety glass. Cutting into a masonry wall may need a lintel and, if the wall is load-bearing, structural calculations; stud walls are usually straightforward.
Questions from Bristol customers
How long does it take to get internal windows and borrowed light fitted in Bristol?
Lead time is typically 3–5 weeks from survey. We'll give you a firm date when you approve the drawing.
Who fits internal windows and borrowed light in Bristol?
Our own installation team, working to the drawing agreed at survey. The same company quotes, manufactures and fits your glazing.
Does an internal window need Building Regulations approval?
Usually not on its own, but forming an opening in a load-bearing wall needs a lintel and Building Control sign-off. Glass near the floor must be safety glass.
