What the fitted estimate includes
Supply of the selected window or door, standard replacement fitting, ordinary removal and basic making good are assumed, with 20% VAT included. Scaffolding, hidden structural defects, major access problems, listed-building requirements and highly bespoke work can sit outside the standard range.
The calculator also widens the range when you use rough sizes, so the result does not pretend to have survey-level precision before measurements are known.
A realistic Southend project example
8 medium white uPVC windows with one opener each currently centre around £4,010, with a broad fitted range of £2,890–£5,135.
The centre is a market benchmark, not a promise that every installer will quote inside the range.
Switching from white to a coloured finish, adding openers or choosing triple glazing changes the product cost before any unusual building work is considered. Use the calculator when you need those choices reflected in the estimate.
