Double Glazing Prices in Cardiff
Cardiff uses our Wales market calibration, which currently sits below the national fitted-price baseline. This guide combines standard uPVC, triple glazing and door pricing so you can compare common project choices.
Current Cardiff price examples
These are fitted market estimates from the same model used by the calculator. They include ordinary VAT and standard replacement installation, but are not binding installer quotations.
1200 × 1200 mm · 1 opener
1200 × 1200 mm · 1 opener
standard door · no side panels
standard white · 1 opener each
The Wales calibration is 6% below the UK baseline. On the standard medium uPVC example that moves the current fitted centre to about £495.
The regional factor is only one part of the price. Triple glazing, coloured frames and door specifications can easily outweigh the difference between Cardiff and the UK average.
How to compare Cardiff quotes
If a Cardiff quote includes triple glazing, compare it with another triple-glazed quote rather than a cheaper double-glazed figure. The calculator keeps those specifications separate.
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.
