What affects the cost of installing a patio door?
Type of patio door
The style you choose makes the biggest difference. Sliding doors are the most affordable, while French and bi-fold doors cost more because of their design and hardware.
Size of the door
The bigger the opening, the higher the cost. Larger doors need more material, bigger glass panels and more time to install.
Material
uPVC is the most budget-friendly material. Timber sits mid-range to premium, and aluminium typically carries the highest prices thanks to its slim sightlines, strength and durability.
Glass type
Double glazing is the standard choice. Triple glazing improves insulation and soundproofing but costs more; our double vs triple glazing guide weighs up whether it is worth it. Single glazing is rare for external doors and often does not meet building regulations.
Location
Where you live affects labour and material rates. Homes in London and the South East typically face higher installation prices than the rest of the UK.
Installation complexity
A straightforward like-for-like swap costs the least. If the opening needs structural work, a new lintel, or your home is older and needs adjustments, expect to pay more. The experience and reputation of your installer also feed into the final price.

Sliding vs French vs bi-fold doors
Sliding doors: £600 to £1,800
The most budget-friendly option. Two large glass panes, one sliding behind the other, give you maximum glass for minimum cost and take up no floor space when open. Modern sliding doors have slim frames that keep sightlines clean, and with fewer moving parts there is less to go wrong.
French doors: £1,200 to £2,400
The mid-range choice. A pair of hinged doors that open outwards (or inwards), French doors suit traditional properties and narrower openings. They open the full width of the frame, but you need clearance for the door swing.
Bi-fold doors: £2,900 to £7,000
The premium option. Multiple panels slide along a track and fold back on themselves, opening up almost the entire wall. Prices climb with the number of panels and the span. If you are leaning this way, our dedicated bi-fold door cost guide breaks prices down by configuration.
Patio door costs by material
- uPVC is the most affordable, usually £350 to £1,200 for the door set. It insulates well and needs almost no maintenance.
- Timber is a mid-range to premium choice at £600 to £3,000. It looks superb but needs periodic upkeep.
- Aluminium carries premium pricing at £950 to £4,200. Its strength allows the slimmest frames and largest glass panels, and it is exceptionally durable.
Glazing options
- Double glazing is the standard choice at £240 to £950 depending on the glass area.
- Triple glazing is more efficient and more secure, typically £600 to £1,800.
- Single glazing is the cheapest but rarely used in external doors and often falls short of building regulations.
Installation costs
Installation prices depend on the complexity of the job and your installer's rates. On average, expect to pay between £300 and £900 on top of the door itself. Structural alterations, such as widening an opening for bi-folds, are quoted separately and can add considerably more.
Conclusion
Adding a patio door is an excellent investment. It brings more natural light into your home and creates an easy connection between your indoor and outdoor spaces. The final price comes down to the style, size, material, glazing, your location and the complexity of the installation, so always get a clear, itemised quote from a trusted installer before deciding.

Are uPVC or aluminium patio doors better value?
uPVC is the budget-friendly choice at roughly £350 to £1,200 for the door itself and performs well thermally.
