Is It Cheaper To Run A Staff Shuttle Or Reimburse Mileage?

If your business relies on employees travelling to a fixed workplace, whether it’s an office, warehouse or business park, you might be weighing up if it is more cost-effective to run a staff shuttle, or simply reimburse mileage. 

On the surface, mileage reimbursement looks simpler. But when you break down the true costs (and the hidden inefficiencies), the answer isn’t always as obvious as it seems.

Understanding mileage reimbursement

Mileage reimbursement is straightforward. Employees use their own vehicles and claim back a set rate per mile, typically aligned with HMRC guidelines. The approved Mileage Allowance Relief is currently 45p per mile for the first 10,000 miles for cars and vans.

Beyond this, drivers can claim 25p per mile, plus an additional 5p per mile for each passenger carried. Employers have the ability to pay more if they wish, but this may be liable to income tax.

At first glance, paying mileage relief might flexible and low effort:

  • No scheduling required
  • No upfront transport costs
  • Employees manage their own travel

But this model comes with hidden costs that build quickly.

The real cost factors include:

  • Mileage payments per employee
  • Increased expense claims administration
  • Variability in daily attendance and punctuality
  • Parking requirements and associated costs

If you have ten to 20 employees all claiming mileage daily, the monthly total can climb faster than expected. 

The allowance is intended to cover fuel as well the maintenance and repair costs of the vehicle. Given the current Gulf crisis and the knock-on effect on fuel prices, many businesses expect the current mileage relief rate to rise in the next Budget

What does a staff shuttle realistically cost?

A staff shuttle – usually a minibus or coach running fixed routes – introduces a more structured cost model.

You’ll typically pay for:

  • A fixed daily or weekly hire rate
  • Driver time
  • Fuel (often included depending on provider)

At first, this can look more expensive than mileage. But the key difference is predictability.

Instead of fluctuating costs based on individual claims, you have:

  • A fixed transport budget
  • Clear capacity (e.g. 16, 34 or 50+ passengers)
  • Scalable options depending on demand

When spread across multiple employees, the cost per head often becomes very competitive.

When does a staff shuttle become cheaper than paying mileage? 

A shuttle starts to make financial sense when:

  1. You have consistent daily attendance

If the same group of employees commute regularly, a shared vehicle reduces duplication. Instead of 15 individual journeys, you’re running one.

  1. Employees travel similar routes

If staff are coming from the same towns or transport hubs, a shuttle route can be planned efficiently.

  1. Parking is limited or expensive

Providing parking for dozens of individual vehicles is costly. A shuttle reduces the need for large on-site parking capacity.

  1. You’re covering medium distances

For commutes of ten to 30 miles, mileage claims can quickly exceed the cost of shared transport. In these scenarios, businesses often find that a minibus or coach lowers the cost per employee per day.

When might mileage reimbursement still work best?

Mileage isn’t always the wrong choice.

It can be more practical when:

  • Staff work irregular shifts
  • Employees are geographically spread out
  • Team sizes are small
  • There’s no clear central pick-up point

In these cases, the flexibility of mileage outweighs the efficiency of a fixed shuttle.

What are the hidden operational benefits of a shuttle?

Cost matters, but it’s not the only factor. Businesses that introduce staff shuttles often notice improvements in areas they didn’t initially consider.

  1. Better punctuality

A scheduled pick-up time reduces late arrivals. Everyone arrives together, on time.

  1. Improved staff retention

Reliable transport removes a daily stress point and boosts staff retention, particularly for employees without easy access to a car.

  1. Wider recruitment reach

You can hire from a broader area, including locations not well served by public transport.

  1. Lower environmental impact

Fewer individual vehicles means reduced emissions; something increasingly important for Environmental, Social and Governance reporting.

Mileage reimbursement looks simple, but it can become expensive and inefficient as your team grows.

A staff shuttle requires more planning upfront, but offers predictable costs, operational control, and a better daily experience for employees. For businesses with consistent teams and shared travel patterns, a shuttle is often a sound long-term investment.
