Rules 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

After the free survey you get a written quote naming the frame system, the glass build-up and the whole-window U-value for every item. Windows are made to order, then fitted, sealed and made good, one opening at a time.

  • Free survey and a written quote fixed for the specification
  • Glass build-up and whole-window U-value on every quote
  • Written handover pack at the end of the job
  • Guarantees on frames, units and fitting in writing
