What a new door costs in 2026
Doors are priced per unit rather than per square metre, and the spread is wide because a simple uPVC front door and a five-panel aluminium bifold are very different jobs. The calculator above supports the two glazed door styles, French and bifold, so you can price those directly. For a front, patio or composite door, use the figures in the table below, which are the fully fitted 2026 ranges we track, cross-checked against Checkatrade and GreenMatch, with the two front door rows re-checked in September 2026 against Checkatrade, MyJobQuote and Costwise. A uPVC front door starts at £460 fitted; a premium aluminium bifold can reach £7,500.
For a front entrance, the real choice is uPVC against composite. uPVC is the value option at £460 to £1,200, typically around £700, and it is low maintenance. Composite has a thicker, heavier leaf and costs more, at £1,150 to £2,500 fitted. Neither is secure by material alone: that comes from a certified doorset and the grade of the cylinder, so check both on the quote. For garden access, French doors and patio sliders do similar jobs differently: French doors swing open and suit a traditional look, and their window-height cousin is the French window, which you can price in the French window calculator, while sliding patio doors save space and give a larger glass area. Whichever you pick, the same rule applies as with windows: check the cost per opening against at least three written quotes.
| Door type | Low | Typical | High |
|---|---|---|---|
| uPVC front door | £460 | £700 | £1,200 |
| Composite front door | £1,150 | £1,500 | £2,500 |
| French doors (uPVC) | £1,100 | £1,650 | £2,200 |
| Patio / sliding doors (uPVC) | £1,500 | £1,850 | £2,200 |
| Bifold doors (uPVC, 3-panel) | £2,000 | £3,500 | £4,675 |
| Bifold doors (aluminium) | £3,000 | £5,000 | £7,500 |

Front doors, garden doors and bifolds
For a front door, composite is our pick where the budget stretches. The extra over uPVC buys a thicker, heavier leaf, more colour choice and, on the door sellers' own figures, a longer life: 30 to 35 years against 20 to 25. It does not buy security on its own. Where budget is tight, a good uPVC front door still does a perfectly respectable job for several hundred pounds less. Timber, aluminium, steel and flat fire doors are priced in our front door cost guide.
For opening up to the garden, the decision is about space and style.French doors and windows at £1,100 to £2,200 in uPVC are the traditional route and need clearance to swing. Sliding patio doors at £1,500 to £2,200 save that swing space and give a bigger unbroken pane. Bifolds are the showpiece option: a uPVC three-panel set runs £2,000 to £4,675, while an aluminium bifold, with its much slimmer frames, costs £3,000 to £7,500. If your project is really about replacing windows rather than doors, the uPVC window calculator, the aluminium window calculator and the timber window calculator will price those instead.
The verdict on doors
For most front entrances where the budget stretches, a composite door is the Best Buy: a thicker leaf and the longest life the door sellers claim, for about twice the typical uPVC figure in the table. Ask for a PAS 24 certified doorset and a 3-star cylinder whichever you choose, because that, not the material, is what makes a door hard to get through. For garden access, the choice between French, patio and bifold is more about how you want the opening to work than about which is better, so let the space decide. And before replacing a door that drags or will not lock, check whether it simply needs adjusting on its hinges and keeps, which is a ten-minute job on most uPVC and composite doors.
Best Buy Composite front door, at around £1,500 fitted, is our Best Buy for a front entrance in 2026, provided the quote names a 3-star cylinder.
If you are buying the door supply-only and fitting it yourself, the fixings, the threshold rule and the building notice are covered in how to fit a uPVC door.
On a front door, read the spec sheet before the brochure. The lock is only as good as its cylinder, and that is a line on the quote, not a property of the material: composite doors are sold with 1-star cylinders too. On bifolds, do not skimp: a cheap uPVC set on a wide opening will sag and stick. If the span is big, pay for aluminium and slim frames.

The benchmarks above are £460 to £1,200 fitted for a uPVC front door, £1,150 to £2,500 for composite, £1,100 to £2,200 for uPVC French doors and £1,500 to £2,200 for patio. For a price on your actual opening, tell us what you need and Leads 2 Trade will arrange quotes from installers covering your postcode.
Ask what the price covers beyond the door leaf itself. The frame, the threshold, the cylinder and the handles are all specification choices, and the security rating on the cylinder is the one line not worth saving money on. The star ratings, and what swapping a cylinder costs if yours falls short, are in how to change a uPVC door lock.
