How this is worked out
The number of windows you pick, times Expert Windows & Doors' published installed price a window for that frame. BuildTech's published price a window is shown next to it where it gives one. The multiplication is ours. Prices read on 3 November 2026. Neither page says whether VAT is in. Size counts: a big picture window or a bay costs more than a small bathroom window, and doors are extra. It's an estimate, never a quote.
