On average, patio door replacement costs somewhere between £2,000 - £4,000.
Most replacements take one to two days to complete, depending on the door type and whether any structural work is needed.
Now let's break down those costs by door type, frame material, and glass type so you can build an accurate budget.
Patio door cost by type
Supply-and-fit prices vary widely by door type. Here's what you can expect to pay across the main options.
£3,000-£5,000 on average for bi-fold patio doors
£3,000-£5,000 on average for sliding patio doors
£1,500-£2,500 on average for French doors
uPVC is the most common choice for budget-conscious homeowners. Aluminium sliding doors and bifold door installation suit larger openings or a more premium finish, but you'll pay more for both.

Patio door installer hourly rates
The average hourly rate for a patio door installer is around £40 per hour.
Most installers will charge a day rate or a total project price rather than an hourly rate, depending on the size of the job. You can expect to pay around £300 per day.
Labour costs also run higher in London, the South East, and remote locations.
Sliding door replacements are generally a one-day job, while bifold installations can take one to two days, especially if a new or enlarged opening is needed.
A typical quote from a tradesperson covers removal of your old door, fitting the new one, sealing around the frame and disposal of the old unit.
What affects the cost of replacing a patio door?
Several factors push the price up or down. Here are the main ones to factor into your budget.
Type of frame
uPVC doors are typically at the cheaper end of the spectrum, at around £1,500-£4,000. Meanwhile, aluminium sliding doors cost around £2,000-£4,500.
Composite frames are a newer option that sits between uPVC and aluminium on price. They give you better insulation than uPVC with a more durable finish, without reaching full aluminium prices.
Type of glass
Double-glazed patio doors are now the norm for energy efficiency. Tempered or laminated glass costs more than standard glass, but it gives you extra privacy and security.
If you're comparing the double glazing cost against triple glazing, it's worth remembering that triple glazing adds to your upfront cost, but you'll save money over time on energy bills, as it cuts heat loss further.
Low-E (low-emission) glass is another option that raises your price tag but reduces your energy bills over time.

Size of door
The bigger the patio door, the higher your overall cost.
You're looking at around £3,000 to replace a double-panel glass sliding door. If you need to replace a three-panel door, you can expect to pay closer to £4,500.
Door mechanism
French doors are a popular choice for patio doors, with prices ranging from £1,500-£2,500.
A glass sliding door replacement will be more expensive, at closer to £3,000-£5,000.
A bifold four-panel door will typically set you back £3,000-£5,000.
Composite doors are also available in sliding and French configurations, and tend to sit in the mid-range on price.
Your location
Prices tend to skew higher in London and big cities compared with quotes in rural areas, due to higher labour costs in those areas.

FAQs
Yes. If you're happy with your current frame, replacing just the glass is possible and will cost less than a full door replacement. Replacing the glass alone can bring your doors back to life while keeping costs low.
If the glass is broken, this can also be the faster route since broken glass is a security risk that needs sorting quickly.
If you measure the glass yourself and fit it, this costs around £200. If you'd rather hire a tradesperson, they'll usually charge a day rate of around £300 on top of materials.
The exact price depends on the type of patio door, the glass you choose, and your location. Speak to a window or door installer to get an accurate quote.
Double-glazed patio door glass costs between £150 per square metre. Low-emission glass runs to £175 per square metre but reduces your heating bills over time.
Patio doors are generally double-glazed as standard these days. If you're choosing a brand new door, it most likely comes double-glazed without any additional costs.
It's unlikely, but can happen. Improper installation can make patio doors vulnerable to cracking and shattering without warning.
If your glass has broken unexpectedly, the edges of the glass were likely chipped during fitting, causing it to sit loose in the frame. A professional can replace the glass within a few hours.
No, it's not advised. Contact an installer unless you have direct experience replacing patio doors.
Incorrect installation can void your insurance or put you outside building regulations compliance - your home's safety is not worth risking.
If you're modifying or creating a new opening, a structural engineer may also be needed before work starts.
Replacing a conservatory door typically costs between £1,500-£5,000, depending on the door style and material. French doors and sliding doors are both common choices for conservatories.
Most patio door replacements take between half a day and two days, depending on the door type and whether structural changes are needed.
Sliding door replacements are at the quicker end, while bifold installations can take longer if new openings are being created.
No. In most cases, replacing a like-for-like patio door does not need planning permission, as it counts as permitted development.
However, if you live in a listed building or conservation area, check with your local council first.
