It is one of the most common questions homeowners ask before investing in bifold doors: will they add value to my property? The honest answer is that they usually make a home more appealing, but the size of any benefit depends on your home, your location and the quality of the installation. Here is what we can say with confidence, without the hype.
How much value do bifold doors add?
You will see percentage figures quoted online, but there is no reliable published data that isolates the value bifold doors add on their own. A valuer looks at the whole property — its size, layout, condition and location — rather than individual features. What bifold doors can do is make a home more appealing at viewings, especially when they are part of a well-designed extension.
Why bifold doors appeal to buyers
Most of the appeal comes from how bifold doors make a home feel rather than the doors themselves. Open-plan living with direct garden access is a popular feature with buyers, and a wall of glass that floods a kitchen or living room with light makes a space feel larger and more modern at viewings.
- More natural light, which makes rooms feel bigger and brighter
- A seamless connection between the kitchen or living space and the garden
- A modern, high-specification look that photographs well in property listings
- Better thermal efficiency than older patio doors, which appeals to energy-conscious buyers
How to protect the value bifold doors add
- Choose aluminium over uPVC for slimmer frames, larger glass and a premium finish that lasts
- Use a reputable system such as Schüco or Cortizo with a proper written guarantee — our Schüco vs Cortizo guide compares the two
- Keep the paperwork: a buyer's solicitor will ask for evidence of Building Regulations compliance, either a competent person scheme certificate (such as FENSA or CERTASS) or a building control completion certificate — see our building regulations guide
- Match the doors to the home — oversized or poorly proportioned glazing can look out of place and undo the benefit; our guide to bifold door panel configurations helps you size them

Frequently asked questions
Do bifold doors add value to a house?
They usually make a home more appealing to buyers, particularly as part of a well-designed extension, but there is no reliable figure for the value they add on their own. The quality of the doors and installation, and how well they suit the house, matter most.
Will I need a certificate for my bifold doors when I sell?
Usually, yes. Replacing an external door that is more than half glazed, such as a bifold, is notifiable building work, so a buyer's solicitor will normally ask for a competent person scheme certificate, such as FENSA or CERTASS, or a building control completion certificate.
