Anatomy of a window quote
Most quotes follow the same shape once you know what to look for. Here is what each part is telling you.
-
Units & sizes
The number of windows, their style and measured dimensions.Check every opening is listed and the style matches what you asked for.
-
Specification
Frame material, glass type, U-value and any energy rating.This is where quotes quietly diverge — the numbers behind the price.
-
Labour & fitting
Removal of old units, installation, making good and waste removal.Confirm whether plastering or making good is included or extra.
-
Guarantee
What is covered, for how long, and whether it is insurance-backed.A long guarantee only helps if it is genuinely backed.
-
Payment terms
Deposit, stage payments, the balance and any finance.Look for deposit protection and clear, written terms.
