Double Glazing Cost for a 3-Bedroom House
A 3-bedroom house is the most common double glazing job in the UK. Here is what it costs in 2026, an itemised breakdown of a typical £6,500 quote, and what pushes the price towards either end of the range.
Key takeaways
- A 3-bedroom house typically costs £4,000 to £9,000 for seven to nine windows and a front door in white uPVC.
- Terraced houses sit at the lower end, detached houses with bays at the upper end.
- Scaffolding, disposal and making good are usually 10% to 20% of the total.
- An itemised quote should list every opening, so you can compare two installers fairly.
Three-bedroom houses are the backbone of the UK housing stock, and the most quoted double glazing job. They are also where most of the confusion lives, because a three-bed terrace with six windows is a very different job from a three-bed detached with ten windows, a bay and two doors, even though both are described as “a three-bed”.
Typical cost by house type
| House type | Windows | Doors | Typical range |
|---|---|---|---|
| 3-bed terrace | 5 to 7 | 1 | £3,600 – £7,000 |
| 3-bed semi-detached | 7 to 9 | 1 | £4,000 – £8,500 |
| 3-bed detached | 9 to 11 | 2 | £5,500 – £9,000+ |
| 3-bed bungalow | 6 to 8 | 1 | £3,400 – £7,200 |
An itemised example: £6,500 for a 3-bed semi
This is a realistic mid-market quote for a three-bedroom semi with eight windows and a composite front door, and it shows why comparing totals alone tells you very little.
| Item | Detail | Cost |
|---|---|---|
| Front bay window | Three-section uPVC bay, new roof | £2,100 |
| 3 x bedroom windows | Casement, 1200 x 1200mm | £1,350 |
| 2 x rear windows | Casement, 1200 x 1500mm | £1,050 |
| 1 x landing window | Fixed light, 600 x 900mm | £340 |
| 1 x bathroom window | Obscure glass, top-hung | £390 |
| Composite front door | Supplied and fitted | £1,150 |
| Scaffolding | Front elevation only | £650 |
| Removal and disposal | Old frames and glass | £180 |
| Making good | Internal plaster and trim | £290 |
| Total | VAT included | £7,500 |
What moves a 3-bed quote up or down
- Number of openings. Every additional window adds £400 to £800. A house with eleven openings rather than eight is a materially bigger job.
- Bays and shaped windows. A bay needs support, a roof and more frame sections, typically £1,200 to £2,600 each.
- Doors. A composite door is £900 to £2,500 fitted, bi-folds far more.
- Access. First-floor windows over a conservatory, or work above two storeys, needs scaffolding at £500 to £1,500.
- Colour. Anthracite grey outside with white inside adds 10% to 25% to the frame cost.
- Window count versus window size. Four large windows can cost more than seven small ones, so count area as well as number.
How to brief a 3-bed quote properly
Walk the house with the surveyor and agree the list of openings before anyone quotes. Ask them to note which windows open, which are fixed, which need obscure glass, and whether the bay needs a new roof. Then send the same list to two more installers. Three quotes against an identical list gives you a real market price and a strong negotiating position.
The bottom line
For a three-bedroom house, £4,000 to £9,000 covers most white uPVC installations with a front door. Get three itemised quotes on the same list of openings, check disposal, making good, certification and scaffolding are included, and expect two to three days on site once the fit starts.
Frequently asked questions
Around £4,000 to £8,500 for seven to nine windows and a front door in white uPVC. Adding a bay, aluminium frames or a second door pushes the figure towards the top of the range.
Usually five to nine on the elevations, plus often a landing and bathroom window. Detached houses tend to have more, and some have windows on all four sides.
No. Per-window prices are higher in small jobs because fixed costs are not spread, and you may pay for scaffolding twice. A whole-house quote is almost always better value.
Two to three days for eight or nine windows and a door, with the front elevation and any scaffolding work usually done first.
