If you're comparing double glazed doors for your home, understanding the likely costs upfront can help you budget more accurately.

Whether you're replacing an ageing front door, opening up your home with classic French doors or considering bifold doors for a modern renovation project, costs can vary significantly depending on the style, size and specification you choose.

In this guide, we'll break down the average cost of double glazed doors, installation costs and the factors that can affect your final quote.

How much does a double glazed door cost?

The cost of double glazed doors varies depending on the door style, glazing design and overall size.

As a rough guide, a standard double glazed front door costs around £600–£700, while French doors typically cost between £950–£1,175. Larger patio doors and bifold doors can cost considerably more.

NB. These costs don't include any additional building work that might be required before fitting the doors.

• Front doors generally represent the lowest-cost option, while larger French doors, patio doors and bifold doors tend to sit at the higher end of the price range

• Size plays a major role in the overall cost, but security features, glazing style and overall specification can also have a noticeable impact on price

Trades Top Tip

"Consider investing in the best quality you can afford for your front door. Cheaper solutions are often not as durable and will likely require replacing after a short period of time."

French door cost

French doors continue to be one of the most popular choices for connecting living spaces with gardens and patios.

Typical costs include:

• 1.2m French doors: £950–£1,050

• 1.5m French doors: £1,000–£1,100

• 1.8m French doors: £1,075–£1,175

Cost of patio doors

Patio doors offer a practical space-saving solution because they slide rather than swing open.

The cost of patio doors typically ranges from £450–£1,800 depending on size and specification.

French doors vs patio doors

If you're deciding between French doors and patio doors, the biggest difference is how they open. French doors are hinged and open inwards or outwards, while patio doors slide along a track. Patio doors are ideal where space is limited because the sliding panels don't need any clearance to open.

French doors, on the other hand, tend to suit period and traditional properties and can create a wider opening to the garden when both doors are fully open.

Bifold door cost

Bifold doors are usually the most expensive option because of their size, complexity and installation requirements.

Expect to pay from around £5,000+ depending on size.

Labour costs for installing double glazed doors

The average labour cost to install double glazed doors is around £225–£300 per day.

What affects the cost of double glazed doors?

Two doors can look very similar at first glance but have very different price tags. That's because several variables can affect the cost, including:

• Door size: Larger doors require more materials and can take longer to install

• Door style: Front doors, patio doors, French doors and bifold doors all have different manufacturing and installation costs

• Security specification: Upgraded locks and enhanced security features can increase costs

• Glazing design: Decorative glazing, leaded designs and specialist glass options tend to cost more

• Door colour: White is usually the most affordable choice, while bespoke colours often carry a premium

• Material quality: Higher-quality products generally offer improved durability and performance but come at a higher price

• Accessories: Handles, door furniture and other special accessories will add to the cost of your double glazed door

• Location: Labour costs vary across the UK

Additional costs to budget for

It's easy to focus on the price of the door itself, but there can be a few additional costs to factor into your budget too, for example:

• Upgraded locks and security features: High-security locking systems often cost more than standard options

• Decorative glazing: Patterned, leaded or privacy glazing can increase costs

• Bespoke colours and finishes: Custom finishes usually cost more than standard white frames

• Removal and disposal of old doors: Some installers include this as standard, while others charge separately

• Making good around the opening: Minor repairs, redecorating or trim replacement may be needed after installation

• Structural alterations: Larger openings for patio or bifold doors may require additional building work

What's included in a double glazed door installation quote?

Quotes can vary between installers, but most should clearly state what's included.

Double glazed doors: DIY vs professional installation

If you're confident with DIY, you may be tempted to fit a door yourself.

However, double glazed doors are heavy, need to be installed accurately and must seal correctly to perform as intended.

Professional installation offers:

• Correct alignment

• Improved energy efficiency

• Better security performance

• Reduced risk of future problems

For most homeowners, professional installation is money well spent.
