Why specifications still matterRegion is only one input

For Liverpool projects, the number of windows matters because mobilisation and fitting costs are spread more efficiently across a larger standard-window job.

How to compare Liverpool quotes

Do not judge a quote only by cost per window. A cheap-looking average can hide a mix of small fixed lights and large opening windows, while a higher average may include bays or premium specifications.

Always compare like with like: dimensions, opening sections, frame system, colour, glass, removal, fitting and VAT.

What the fitted estimate includes

Supply of the selected window or door, standard replacement fitting and ordinary 20% VAT are included. Scaffolding, hidden structural repairs, listed-building requirements, major access problems and highly bespoke work can fall outside the standard range.
