The range of internal bifolding doors from Leader Online

Our internal bifolding doors come in the following door types and finishes.

Colours:

• Oak Bifolding Doors - Add a traditional, rustic charm to your property with our oak bifold internal doors, which are warm and full of character. They suit both traditional and contemporary interiors.
• Pine Bifolding Doors - Opt for an airy, bright, and cosy feel with our pine internal bifold doors, which give the perfect blend of affordability and lasting luxury.
• White Bifolding Doors - Add to the clean, minimalist look and feel of your space by opting for white internal bifolding doors. This neutral colour is timeless and unerringly desirable, adding much-needed light to modern and traditional interiors.

Types:

• Glazed Bifold Doors - Let natural light flow freely between rooms while maintaining a clear division with our glazed bifold internal doors. These types of doors are perfect for kitchens, dining rooms, and hallways where you want to create an open-plan yet clearly defined space.
• Shaker Style Doors - Our shaker-style folding internal doors feature a clean panel design that works in both modern and traditional interiors.
• Industrial Style Doors - Inspired by the steel-frame industrial Crittall windows first introduced in the late 19th century, these doors are modern and timeless in equal measure.

Finishes:

• Fully Finished - Our fully finished bifold doors arrive with a factory-applied coat of lacquer and are ready to hang straight out of the box. No painting or staining is required at your end, which saves you time and stress.
• Primed - Our primed internal bifolding doors already have a base coat of white primer and are ready for you to apply your topcoat in the colour of your choice. When you do this, make sure you use a compatible paint, apply paint in thin coats, and avoid painting over hinges and certification labels.
• Unfinished - Unfinished internal bifolding doors are raw timber, meaning you have complete creative control over the look and feel. You can sand, stain, paint, or oil it so that it matches your wider aesthetic.

These are some of the most common questions we get from our customers regarding internal folding doors.

What are internal bifolding doors?

Bifold doors, also known as concertina doors, comprise multiple panels hinged together. They are engineered to fold back against themselves, allowing the panels to neatly stack to the side when fully opened. Thanks to their unique mechanism, internal bifolding doors are commonly used to create large, impressive openings and seamlessly connect adjoining spaces — such as living and dining rooms — without the intrusion of a standard swing door.

How much do internal bifolding doors cost?

An internal bifolding door from Leader Online typically costs between £120 and £300. Factors influencing the exact cost include size (number of leaves), material, and finish.

• Single Bifolds (£120 - £250): For smaller openings (like closets or en-suites), single bifold units are an affordable, entry-level option.
• Premium Single Bifolds (£200 - £300): If you’re in the market for a more premium folding door, consider solid oak internal bifold doors and glazed options with clear, frosted, or decorative glass designs.

What are the benefits of installing internal bifolding doors?

Installing internal bifold doors in your property allows you to maximise usable space as they can stack neatly to the side, unlike standard doors that require a wide swing arc. If you’re looking to flood rooms with light, internal bifolding doors do this. They allow abundant natural light into your home, negating the need for artificial lighting.

They also make flexible living (or zoning) possible. You can either keep them closed to create cosy, private rooms (zoning), or fold them back to create a seamless, "broken-plan" flow.

Finally, when you purchase one of our internal bifolding doors, you’re taking advantage of their adaptable design. Our range is available in a variety of materials and finishes, from oak to pine and multiple glazed options, making bifold doors a perfect fit for both contemporary and traditional home designs.

Why choose internal bifold doors?

Internal bifold doors require significantly less clear space in which to open than a standard hinged door. That’s why they’re the best choice for kitchens, pantries, utility rooms, and any other areas in which space is at a premium.

They work well in commercial spaces, too. If you want to create an open, collaborative office environment that encourages interaction, you can do this with internal bifold doors by connecting breakout areas, and communal spaces.

In truth, these doors work in just about any setting, whether you're dividing a home office from a living room or renovating an office canteen. They give you a specific form of design flexibility that standard hinged doors don’t.

Do bifold doors need a track?

Yes, all internal bifold doors require a track to guide the doors and support their weight. The type of track depends on the system you choose.

Most internal bifold doors use a top-hung system, whereby the panels hang from a track mounted in the head of the frame. The doors glide along this overhead track, with a small pivot or guide pin at the bottom to keep them aligned. This is the most common system for internal bifolding doors because it creates a cleaner floor line. It’s the safest and most practical option. There's no raised threshold that people could trip over or that interrupts the flooring between rooms.

Some sliding or folding door tracking systems include a low-profile floor guide or bottom track that sits on the floor. This can improve stability, particularly if you’ve got wider openings with multiple panels, but it may introduce a slight threshold or small step between rooms.

If you’re installing your internal bifolding doors over existing flooring, a top-hung system is your best bet as you’re not having to cut into or work around the finished tiles or laminate.

The track, running gear, hinges, and frame components are typically included in the bifold door set when you buy from Leader Online.

How do I maintain bifold doors?

Internal bifold doors are relatively low maintenance, but you can keep them operating smoothly and looking good for many years by following the below steps.

• Check the track and running gear every few months. The build-up of dust can cause your bifold doors to stick or judder. That’s why it’s worth giving them a quick wipe with a dry cloth or a blast of compressed air every now and again to keep the track clear. If your doors still feel stiff, apply a small amount of silicone-based lubricant to the rollers and pivot points. This will make them operate smoothly again. Avoid oil-based lubricants, as these attract more dust over time.
• Clean the door panels just as you would with any internal door. For finished or primed doors, wipe in circular motions using a soft, damp cloth and mild soap. For unfinished timber, dust regularly and apply a protective treatment (varnish, oil, or wax) as needed to prevent moisture absorption. For glazed panels, use a glass cleaner or a white vinegar and water solution, and dry with a lint-free cloth to avoid the appearance of wet streaks.
• Tighten the hinges twice-yearly. A bifold door’s hinge screws can loosen over time due to regular folding and unfolding. You can prevent them from becoming misaligned by checking them with a screwdriver every six months.
