Winter light and glass choice in Inverness

Rules for sash windows in Scotland
Scotland requires replacement windows to achieve 1.6 W/m²K, which good triple glazing passes comfortably. Replacing a window or door, frame and all, does not need a building warrant, but the work must still meet the building standards.
Planning: Since May 2024, replacement windows on houses are widely permitted development, including in many conservation areas, with front elevations expected to match the existing closely; your council tells you if prior notification applies. Flats outside conservation areas generally need permission only if the opening size changes. Listed buildings need listed building consent.
How it works
You will know exactly what you are buying: the quote states the unit build-up, frame, finish, fitting work and how Building Regulations compliance is handled. On fitting day each opening is replaced and closed up before the team moves on.
- Every opening measured, including escape and vent needs
- Frames rated for the weight of triple glass
- Old windows removed and taken away
- Each opening closed up the same day
