Door replacement cost covers a lot of ground, from a simple internal door to a glazed aluminium back door, so a single figure never quite fits. This guide breaks it down by door type, with realistic 2026 price ranges, so you can budget sensibly whether you are swapping one internal door or replacing every external door in the house.
These are guide ranges rather than a fixed price, because size, style and the state of your openings all move the number. A measured quote gives you the firm figure.
Internal door replacement cost
Internal doors are the cheaper end of the scale, and the main variables are the door itself and whether the frame needs any work.
- Basic hollow-core door: roughly 20 to 60 pounds for the door alone, plus fitting.
- Solid or engineered internal door: roughly 60 to 250 pounds for the door, plus fitting.
- Fitting per door: typically 60 to 150 pounds if the existing frame and hinges are sound.
If you are hanging a door into an existing frame, the job is quick. If the frame is out of square, the door needs trimming, or you want new architrave and ironmongery, add for the extra time and materials.
External door replacement cost
External doors do more work, so they cost more. They need to be secure, weathertight and well insulated, and the frame is usually replaced along with the door.
As a rough 2026 guide, supplied and fitted:
- uPVC door: roughly 700 to 1,400 pounds. Affordable, low maintenance and secure. See our uPVC doors.
- Composite door: roughly 1,000 to 2,200 pounds. Tough, well insulated and available in many styles. See our composite door range.
- Aluminium door: roughly 1,800 to 3,500 pounds or more. Slim, strong and modern.
A back door tends to sit at the lower end, while a front door with glazing, a fanlight or side panels climbs higher.
Patio and bi-fold door replacement cost
If you are replacing a back door with something that opens up to the garden, the figures step up again. As a rough 2026 guide, bifold and sliding patio doors typically range from around 3,000 to 8,000 pounds or more supplied and fitted, depending on the width of the opening and the number of panels. You can see the options in our sliding and bi-fold door range.
What moves a door replacement cost
Across every door type, the same handful of factors decide where you land.
- Material. uPVC is the most affordable, composite sits in the middle, aluminium at the top for external doors.
- Size and style. Bigger doors and decorative or glazed designs cost more than a plain slab.
- Glazing and side panels. Glass in the door, a fanlight or side panels add to the total.
- Hardware and security. Quality handles and a good multi-point lock add a little and are well worth it on an external door.
- The opening. If the old frame comes out cleanly, fitting is quick. Resizing the opening, making good the brickwork or rebuilding a threshold adds labour. Older York homes sometimes need this.
Repair or replace?
Not every tired door needs replacing. If a door is sound but sticking, draughty or missing a bit of security, a repair, a new lock or an adjustment is often cheaper and does the job. We handle door and window repairs too, and we will tell you honestly when a fix beats a full replacement.
Replacement makes more sense when a door is rotten, warped, letting water in, poorly insulated or no longer secure. At that point you are paying to keep an old problem alive rather than solving it.

FAQs
How much does it cost to replace an internal door in 2026?
As a rough 2026 guide, an internal door costs around 20 to 250 pounds depending on whether it is hollow-core or solid, plus roughly 60 to 150 pounds for fitting if the frame is sound. New frames, trimming or ironmongery add to the total.
How much does it cost to replace an external door?
Supplied and fitted, expect roughly 700 to 1,400 pounds for uPVC, 1,000 to 2,200 pounds for composite and 1,800 to 3,500 pounds or more for aluminium as a 2026 guide. Glazing, side panels and the opening move the figure, so get a quote.
Is it cheaper to replace just the door or the whole frame?
Replacing the door alone is cheaper if the frame is sound and the sizes match, which is common with internal doors. External doors usually come as a set with the frame, because the seal and security depend on the frame fitting properly.
Should I repair or replace my door?
Repair if the door is sound but sticking, draughty or missing a bit of security, as a new lock or adjustment is often enough. Replace if it is rotten, warped, letting water in or no longer secure. We will give you an honest steer either way.
