A uPVC stable door typically costs £900 to £1,800 supplied and fitted in 2026, making it one of the most versatile and affordable external door choices for UK homes. This guide covers how stable doors work, the styles, colours, glazing and security options available, and how uPVC compares with composite on price.
When looking for a new external door for your home, you have a choice of many styles, but none more versatile than the uPVC stable door. Stable doors offer practicality and flexibility that suit the modern lifestyle, and they work with both contemporary and traditional properties.
Choosing a uPVC or composite stable door delivers a strong, durable, low-maintenance and energy-efficient door, and you can pick a colour and finish to suit your interior and exterior decor. Here we outline almost everything you need to know about stable doors before you make your final choice.
What are stable doors?
Stable doors are similar to standard external doors but are split into top and bottom sections. These sections open and close independently, so you can open the top half without the bottom, or open, close and lock them together like a regular door.
Many stable doors are designed on a 50:50 basis, with the top and bottom sections equally sized, but this can be adjusted to make one part larger than the other.
How much do stable doors cost in 2026?
The table below shows typical 2026 guide prices for stable doors. Exact quotes vary with size, colour, glazing and the security specification you choose.
| Stable door type | Supply-only | Supplied and fitted |
|---|---|---|
| uPVC stable door | £700 to £1,300 | £900 to £1,800 |
| Composite stable door | £1,100 to £2,000 | £1,400 to £2,600 |
A plain white uPVC stable door with solid panels sits at the bottom of the range; glazed sections, woodgrain and coloured finishes, and upgraded locking push the price towards the top. For context against standard door types, see our uPVC door cost guide and composite door price guide.

uPVC stable doors vs composite stable doors
You may be wondering what the difference is between uPVC and composite.
- uPVC is unplasticised polyvinyl chloride, a lightweight and robust vinyl often used in windows and doors. A uPVC door usually has vacuum-pressed panels and dense polystyrene at the core with an outer uPVC frame.
- Composite doors are made from resilient glass reinforced polymer (GRP), bonded with a solid centre of foam and a timber frame with uPVC banding for the locks and hinges. The door is composed of several different materials to combine the best qualities of each, hence the name composite.
Both composite and uPVC stable doors offer a range of features and benefits that appeal to homeowners, including:
- High energy efficiency ratings
- High durability with a long lifespan
- Wide choice of styles, including glazed options
- Wide range of colours and finishes, including woodgrain
- Effective security features
- Easy maintenance with no need to repaint or sand
This is why it is often difficult to choose between them. Generally speaking, though, uPVC stable doors are less complex to produce and less expensive than composite stable doors, typically £900 to £1,800 fitted against £1,400 to £2,600.
Price is a significant deciding factor for many buyers, and as uPVC offers a high-quality finish at the lower cost, it is not difficult to see why uPVC stable doors are so popular.
Coloured stable doors
Both uPVC and composite stable doors are available in various colours and finishes. The number of colours you can choose from will vary by supplier, and you may be able to select a finish that resembles wood grain for a more traditional aesthetic.
Some homeowners even choose a different colour on the inside and outside of the door. For example, they may select white for the interior to blend in with their kitchen while using a bolder colour on the exterior.
One difference between the two materials: on uPVC stable doors the colouring is bonded to the surface, while composite doors are made from coloured materials throughout, which can make the finish more durable.
Glazing
Several glazing options are available with stable doors, and many homeowners choose to include glass sections in the design.
You might opt for a half-glazed door using plain, patterned, frosted or lead glass, or a part-glazed door where a shaped section of glass is used, such as a circle or square. Alternatively, you can choose solid panels for maximum privacy.
Security features
uPVC stable doors can include a range of secure and robust locking mechanisms that improve the security of your home.
The most popular choice is multi-point locking. The top and bottom sections of the door can lock independently and be locked together. While standard doors typically have two or three hinges, stable doors can also be fitted with a heavy-duty four-hinge configuration to provide extra strength when closed.
Quality uPVC stable doors also include a core of galvanised metal for reinforcement and an extra level of security. This reinforcement helps prevent the uPVC frame from warping over time, which is what causes some doors to stick or jam in the frame.
Finally, if a section of the door is glazed, you can specify high-security glass within the door design, such as toughened or laminated glass. A glazed section can also be beaded internally, preventing the glazing from being removed from the frame by an intruder outside the door.
Where to install a stable door
uPVC stable doors and composite stable doors are ideal external doors, at either the front or the back of the house.
They are most commonly installed as back doors, giving homeowners an easy way to ventilate the home with fresh air while keeping pets and children safely inside.
Stable doors can be used as front doors, but bear in mind that an open top half gives people passing by or arriving at the door instant visibility into your home. Depending on how secure your back garden is, most homeowners find the rear of the property the more practical spot.

Frequently asked questions
How much does a uPVC stable door cost?
A uPVC stable door typically costs £900 to £1,800 supplied and fitted in 2026, with supply-only prices from around £700 to £1,300. Glazed sections, woodgrain foils and coloured finishes push prices towards the top of the range.
How much does a composite stable door cost?
A composite stable door typically costs £1,400 to £2,600 supplied and fitted in 2026. Composite costs more than uPVC because of its multi-material construction, which combines a GRP skin with a solid core for extra strength and durability.
What is a stable door?
A stable door is an external door split into top and bottom sections that open and close independently. You can open the top half for ventilation while the bottom stays shut, or lock both halves together and use it like a regular door.
Are uPVC stable doors secure?
Yes. uPVC stable doors can be fitted with multi-point locks on both halves, heavy-duty four-hinge configurations and a galvanised metal core for reinforcement. Glazed sections can use toughened or laminated glass with internal beading so the glazing cannot be removed from outside.
Where is the best place to install a stable door?
Stable doors are most commonly installed as back doors, where the split opening gives easy ventilation and garden access with privacy. They can be used as front doors, but an open top half gives passers-by a view into your home, so most homeowners prefer them at the rear.
Can I get funding towards a new stable door?
Qualifying homeowners may be able to access funding options towards new doors through the Help 2 Buy Windows grant scheme, including reduced prices and flexible payments. The Help 2 Buy Windows grant has nothing to do with the UK government; it is funded 100% by Help 2 Buy Windows through the sale of leads to our clients.
