When are UK window and door companies busiest?

A clear busy season: October is the busiest month for finished jobs and February the quietest, and the gap between them is wide. If your job can be planned, start comparing public evidence before October. That comes from 32,395 dated reviews of finished jobs across the platforms we track (2019, 2022, 2023, 2024, 2025).

For a planned job, compare public evidence before October. February is the quiet end of the year in our review records, not a promise that an individual business can take work. Booking happens weeks or months before a job finishes, so work backwards from when you want it done.

Three honest caveats travel with these charts. First, they show the months finished jobs got reviewed, which lags the work itself by weeks and is not a measure of demand. Second, the December and January dips are partly about people not writing reviews over the holidays, so the winter quiet is overstated. Third, booking happens weeks or months before a job shows up here, so treat the shape as the trade's rhythm, never as a booking calendar. Computed from the dated public reviews we hold for this market over complete years, with 2020 and 2021 left out because lockdowns made those years unusual. The patterns describe our data, not the whole market, and say nothing about any individual business.
