Average cost of double glazed doors in the UK
On average, a double glazed door in the UK will cost between £500 and £2,500, including supply and fitting. The final price depends heavily on the material (uPVC, aluminium, composite, or timber) and the style of door you choose.
| Door material | Average cost (supply and fit) |
|---|---|
| uPVC | £500–£900 |
| Composite | £800–£1,500 |
| Aluminium | £1,000–£2,000 |
| Timber | £1,200–£2,500 |
Note: Timber and composite options tend to be more expensive due to higher material costs and longer production times.
Costs by door style
The type of door also impacts the total cost considerably:
| Door style | Average cost (supply and fit) |
|---|---|
| Front door (single) | £500–£1,500 |
| French doors (set of two) | £1,000–£2,000 |
| Patio sliding doors | £1,200–£2,500 |
| Bifold doors | £2,000–£5,000+ |
| Commercial entrance doors (shopfront) | £1,500–£3,500 |
Larger installations, such as bifold doors or wide patio doors, naturally attract higher costs, particularly if bespoke or made-to-measure.
Additional fees to consider
Beyond the door price itself, there are several other potential costs:
| Fee type | Typical cost |
|---|---|
| Survey fee | £100–£250 (may be refunded if you proceed) |
| Removal and disposal of old doors | £50–£150 |
| Upgraded security locks | £50–£200 per door |
| Decorative glazing or side panels | £200–£600 extra |
| Triple glazing upgrade | Additional £100–£300 per door |
| Building regulation compliance checks | £150–£300 |
Always check whether the quotation you receive includes these extras to avoid unexpected charges later.
Commercial double glazed door costs
Business installations are usually more expensive due to commercial-grade materials and higher safety requirements.
| Commercial door type | Average cost (supply and fit) |
|---|---|
| Standard aluminium commercial door | £1,500–£2,500 |
| Toughened glass shopfront door | £2,000–£3,500 |
| Automatic sliding commercial door | £3,500–£6,000+ |
In commercial settings, additional costs may include:
- DDA compliance (Disability Discrimination Act features): £500–£1,500
- Access equipment (scaffolding, cherry pickers): £500–£2,000
- Out-of-hours fitting: 10–20% premium
Factors that affect double glazed door prices
Key factors influencing how much you will pay include:
- Material: Aluminium and timber doors cost more than uPVC.
- Size: Larger and wider doors cost significantly more.
- Glazing type: Standard double glazing is cheaper than laminated or triple glazing.
- Security features: Multipoint locking systems and security-rated doors raise the cost.
- Installer reputation: Larger national companies often charge more but may offer longer guarantees.
- Location: Installation costs are higher in London and the South East by around 10–20%.
Ongoing maintenance and costs
While double glazed doors are generally low-maintenance, some ongoing costs to expect are:
- Cleaning and inspections: £30–£100 per visit depending on size and access.
- Lock repairs or upgrades: £100–£250.
- Seal or glazing unit replacements: £150–£400 per door if needed after many years.
Composite and aluminium doors require the least maintenance, while timber doors will need repainting or refinishing every 5–8 years (typically £400–£800 for a full refresh).
