Birmingham is the closest thing the UK has to an average for double glazing. Our analysis of 2026 regional data suggests prices here sit almost exactly on the UK average, which means roughly £400 to £1,000 per window fitted and £4,000 to £8,000 for a typical 3-bed. Because it tracks the national figures so closely, Birmingham makes a useful benchmark for the rest of the country. That position comes from one modelled study (ExpertSure 2026), so treat it as an approximate guide, and anchor back to the national detail on our cost by house size guide.
How Birmingham compares with the national average
The national, fully fitted baseline is a uPVC casement at £400 to £1,000 per window and a mid-terrace or 3-bed at £4,000 to £10,000. Our analysis of 2026 regional data suggests Birmingham lands right on that baseline. We present it as an approximate match because it derives from a single modelled study, not a separate survey of Birmingham quotes.
| Measure | UK national | Birmingham (on benchmark) |
|---|---|---|
| Per window (fitted casement) | £400–£1,000 | £400-£1,000 |
| Typical 3-bed | £4,000–£10,000 | £4,000-£8,000 |
| Modelled adjustment | Baseline | 0% |

Three worked examples by house type
Because Birmingham tracks the national average, these examples use the national house-size figures with little adjustment. They are illustrative, not quotes.
Flat (around 4 windows)
A national flat runs about £1,800 to £5,000 fully fitted, and Birmingham sits on that figure, with floor level and access the main variables.
Mid-terrace or 3-bed (around 8 to 10 windows)
The headline Birmingham 3-bed figure is roughly £4,000-£8,000 for standard uPVC, in line with the national £4,000 to £10,000 range and helped by the city's competitive installer market.
Semi-detached (around 10 to 12 windows)
A national semi sits at £5,000 to £12,000, and a Birmingham semi tracks that closely, with window count and specification moving the final price within the range.
Birmingham is about as middle-of-the-road as it gets for window prices, which actually makes it the easiest place to spot a dodgy quote. If a number comes in wildly above or below the national range here, something is off in the spec or the firm. Use the average as your sense-check.

Conservation areas and listed buildings
Birmingham has plenty of period housing and conservation areas alongside its modern stock. Where a conservation area or listed status applies, you may be required to fit timber or heritage-style frames rather than standard uPVC, with planning consent sometimes needed. Timber runs £900 to £2,000 per window nationally, well above uPVC, so confirm your property's planning status with the local authority before ordering.
Getting an accurate Birmingham price
Since our Birmingham figures rest on one modelled source and track the national average, use them as a sense-check and then get at least three written quotes from FENSA-registered installers. It also helps to see how the city sits against others: prices in London run around 20% above the national average, while Manchester comes in a little below it. To price the windows themselves, the uPVC window calculator gives a quick per-window estimate that needs almost no Birmingham adjustment.
Frequently asked questions
Our analysis of 2026 regional data suggests Birmingham sits almost exactly on the UK average, roughly £400 to £1,000 per window fitted and £4,000 to £8,000 for a typical 3-bed. These figures come from a single modelled study, so use them as a guide and get three local quotes.
Because it tracks the national average so closely. Birmingham's mix of diverse housing stock and strong installer competition keeps prices around the middle of the range, so the national, fully fitted figures apply here with little adjustment, making the city a useful yardstick for the rest of the UK.
Birmingham sits in between. Our modelled 2026 figures put London around 20% above the national average and Manchester around 7% below it, while Birmingham sits on the benchmark at 0%. So a Birmingham 3-bed costs noticeably less than the same job in London and a little more than in Manchester.
No. The regional position comes from one modelled 2026 study rather than a survey of Birmingham quotes, so we present it as tracking the national figures rather than as a precise price. Treat it as a guide and get at least three written quotes from FENSA-registered installers.
