Winter light and glass choice in Edinburgh
By midsummer Edinburgh has about 17 h 37 min of daylight, but in December only around 6 h 58 min, with the noon sun at about 11°. Triple glazing keeps more heat in during those long, dark months; big south and west windows may suit solar-control glass for summer.

Rules for sash windows in Scotland
In Scotland, replacement windows must meet 1.6 W/m²K. 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
We start with a survey, not a sales pitch: measurements, the structure above any bays, trickle-vent needs and escape windows. The quote that follows fixes the price, and anything unexpected on the day is agreed with you first.
