If you’re self building, extending or renovating and looking to enhance your home’s connection to the outdoors, chances are you’re weighing up the glazed door options and asked yourself ‘how much do bifold doors cost?’. One of the most popular configurations of glazed door, bifolds work on a concertina principle where the panels fold and stack against each other. It’s possible to open up to 95% of the aperture, making bifolds great for offering easy access to the garden and extending your living space to your patio.
So, how much cash should you set aside for this glazed feature? “The old adage that you get what you pay for applies so much in life, but it is certainly true with bifold doors,” says Edward Stobart, sales manager at IDSystems. “Whilst products may look the same in pictures, attention to detail in the design varies across different manufacturers’ systems – whether that is in terms of thermal efficiency, weather performance or the little added design features like locking panel catches or weathertight flush tracks.”

How will frame material impact bifold door costs?
uPVC bifold doors
The makeup of the frame surrounding your bifold’s glass is crucial to its performance and will have a big impact on its price point. uPVC designs are at the cheap end of the market and won’t have the innate strength of, say, aluminium bifold doors, which allow for wider expanses of glazing within individual panels. uPVC bifold door frames are also likely to be thicker, meaning less glass on display.
The Sunflex SF75 eco bifolds won the 2023 Build It Award for Best Glazed Doors thanks to the system’s outstanding thermal performance
Aluminium bifold doors
Aluminium bifold doors are seen as the go-to option for many homeowners looking to invest in high-quality doors. Lightweight yet ultra-strong, the metal profiles enable slimmer sightlines than with other materials. Generally, you can expect a long life expectancy from aluminium bifold doors. Plus, they offer flexibility in terms of colour thanks to RAL powder coatings.
If you want a premium aluminium product for a reputable supplier, expect to pay a price to match. IDSystems’ impressive SF75eco bifold doors cost around £2,000 per panel, including installation. “For aluminium-framed doors, it is crucial to understand the quality of the product, where it is made and who is installing it,” says Edward.
Lacuna bifolds are painted in complete smooth high or low gloss, complemented with marine-grade handles and hinges
Timber bifold doors
The softwood bifold doors you’ll see at DIY stores are another option in the budget category – you can pick up a 1,790mm x 2,090mm three-panel, clear pine veneer unit from B&Q for £1,697, for instance. However, engineered or composite timber is much stronger than solid wood, plus less likely to warp and flex over time.
For example, Lacuna uses heat-treated composite timber in its bifold doors, which makes the wood very stable and unable to absorb moisture or expand in humid weather. They are priced at around £4,642.32 + VAT (+ £895 for the carriage, incl tail lift) for a 2,500mm x 2,100mm three-panel double-glazed bifold system.
