Double Glazing Costs in Wigan
The Wigan figures are designed around whole-project quote checking. A single window is useful for orientation, but the worked example shows what happens when several different frame types are fitted together under the North West market setting.
From one frame to a full project
Installers do not necessarily price eight windows as eight isolated jobs. Quantity can reduce the effective cost per opening because set-up and fitting are shared across the project.

A worked Wigan project
Take a 8-window project containing 2 three-section casements, 4 medium casements, 2 fixed medium windows. Using the current North West setting and the project-size adjustment, the model centres that mix at about £3,545. A practical fitted comparison band is roughly £2,695–£4,395. The mix matters: replacing one of the fixed frames with an extra opening casement would change the total even though the number of windows stays the same.
Use project totals carefully
If one quote is much lower, check whether disposal, cills, trims or making good have been excluded. A low headline total can grow once those items are added.
For the standard medium example, that produces a fitted centre of about £500 in Wigan.
Separate optional upgrades from the standard white uPVC reference wherever possible.
Put the local price in context
A nearby market can help separate a regional effect from a specification effect.
Common Wigan quote questions
The details most likely to matter when you compare an installer quote.
Can I use these Wigan prices to check an installer quote?
Yes. Match the same frame size, opener layout and specification, then compare the fitted range rather than expecting one exact local tariff.
Does the Wigan benchmark include removal?
A normal replacement assumes ordinary removal and basic making good. Significant structural repairs and unusual access sit outside the standard benchmark.
How much is the medium one-opener example in Wigan?
The current fitted centre is about £500 for a white double-glazed uPVC frame at 1200 × 1200 mm.

Rough measurements are enough to begin; exact dimensions can narrow the range when you have them.
