The basics.
Does the price include fitting?
Yes. The result is a fitted-market estimate. It includes supply, standard installation and ordinary 20% VAT, with standard removal and basic making good assumed for a normal replacement job.
Do I need exact measurements?
No. Rough sizes are enough. Exact width and height simply tighten the estimated range.
Is this an installer quote?
No. It is an independent market estimate designed to show what a competitive fitted quote should broadly look like before you speak to an installer.
See what your project should cost.
Rough sizes are fine. It only takes a few minutes.
