Choosing a wheelchair accessible minibus isn’t just about selecting the right vehicle. One of the biggest decisions you’ll make is choosing the type of wheelchair lift.

For most organisations, the choice comes down to two main options: an inboard wheelchair lift or an underfloor wheelchair lift.

Both are designed to safely load and unload wheelchair users, and both can provide years of reliable service when properly maintained. However, they each have their own advantages depending on how your vehicle will be used.

Whether you’re buying a wheelchair accessible minibus for a school, charity, care provider, local authority or community transport organisation, understanding the differences will help you make the right choice.

What is an inboard wheelchair lift?

An inboard lift is mounted inside the vehicle, usually adjacent to the side or rear access door. When not in use, the lift folds neatly into the passenger compartment.

This has been the traditional choice for accessible minibuses for many years and remains a popular option because of its simplicity, reliability and value for money.

Advantages of an inboard lift

1. Proven reliability

Inboard lifts have been used on accessible vehicles for decades and have an excellent reputation for reliability. Their relatively straightforward mechanical design means there are fewer moving parts compared with some underfloor systems.

For organisations transporting passengers every day, this can provide real peace of mind.

2. Lower purchase cost

Generally speaking, an inboard lift is the more economical option.

Because installation is less complex, both the initial purchase price and fitting costs are often lower than an equivalent underfloor lift.

For organisations working within tight budgets, this can make accessible transport much more affordable.

3. Easier servicing and maintenance

As the lift is mounted inside the vehicle, engineers can usually access components quickly during servicing or repairs.

This often reduces labour time and can help minimise vehicle downtime.

4. Excellent for regular daily use

Many schools, care providers and community transport operators use inboard lifts multiple times every day with excellent reliability.

The robust design makes them well suited to demanding operational environments.

Things to consider

Like any engineering solution, there are compromises. Because the lift folds into the passenger compartment, it:

• Occupies some interior space
• May reduce flexibility of certain seating layouts
• Can partially obstruct an aisle or footwell depending on the vehicle design
• May slightly alter the feeling of space inside the vehicle

For some operators these compromises are minimal, while for others interior flexibility is a higher priority

What is an underfloor wheelchair lift?

As the name suggests, an underfloor lift is stored beneath the vehicle when not in use.

When deployed, the lift slides out from underneath the floor before lowering to ground level.

Because the mechanism remains hidden underneath the vehicle, the passenger compartment remains completely unobstructed.

Advantages of an underfloor lift

1. More interior space

One of the biggest benefits is that the lift doesn’t occupy valuable cabin space.

Passengers benefit from:

• Wider aisles.
• Improved movement through the vehicle.
• Greater flexibility for seating layouts.
• A more open interior.

This can be particularly useful when transporting a combination of wheelchair users and ambulant passengers.

2. A cleaner interior

Because the lift mechanism remains out of sight, the inside of the vehicle feels less cluttered and more like a conventional minibus.

Many organisations, particularly independent schools, executive transport providers and care organisations, appreciate the cleaner appearance.

3. Improved passenger comfort

Removing the folded lift from the passenger compartment can create a more spacious environment for everyone onboard.

Drivers also benefit from better visibility through the passenger area and fewer obstacles when assisting passengers.

4. Ideal for larger minibuses

Underfloor lifts work particularly well on larger vehicles where operators want to maximise seating capacity without sacrificing accessibility.

Things to consider

Underfloor systems do have some disadvantages.

• Higher purchase price. The engineering required to integrate the lift beneath the vehicle means installation is typically more expensive than an equivalent inboard lift.
• More complex servicing. Because the lift mechanism is located beneath the vehicle, maintenance can sometimes require additional labour.
• Accessing components may take longer than servicing an inboard system.
• Reduced ground clearance. Installing equipment beneath the vehicle inevitably reduces the available ground clearance. For most operators this isn’t an issue, but organisations regularly accessing steep driveways, rural tracks or uneven surfaces should consider whether an underfloor lift is appropriate.
• Greater exposure to the elements. Unlike an inboard lift, an underfloor system is exposed to the elements, surface water, road salt, mud and dirt. Modern lifts are designed to withstand these conditions, but regular servicing and cleaning become even more important to ensure long-term reliability.

Which lift is right for your organisation?

There is no single best option. The right solution depends on how your vehicle will be used.

An inboard lift may be the better choice if you:

• Want the most cost-effective solution.
• Expect heavy daily use.
• Prioritise straightforward maintenance.
• Don’t mind sacrificing a small amount of interior space.

An underfloor lift may suit you better if you:

• Want to maximise passenger space.
• Require a less cluttered interior
• Carry a mixture of wheelchair users and seated passengers
• Are looking for a more premium finish.

It’s not just about the lift

Choosing the right wheelchair lift is only one part of choosing or designing an accessible minibus.

You’ll also need to consider:

• The number of wheelchair positions required
• Passenger seating capacity
• Wheelchair restraint systems
• Cantrail systems for correct shoulder restraint positioning
• Storage requirements
• Whether a diesel, hybrid or electric power train is most suitable.

Every organisation’s needs are different, which is why it’s important to look at the complete vehicle rather than focusing on a single feature.
