The 2026 Budget brings a mixed picture for the UK fleet industry. While the extension of the 5p-per-litre fuel duty cut offers some welcome short-term relief, a number of tax changes coming over the next few years are likely to put extra pressure on fleet budgets.
From rising Benefit-in-Kind (BIK) rates and the introduction of electric vehicle road charging to changes in capital allowances. Fleet operators will need to think carefully about how they manage costs and plan for the future.
The challenge is particularly significant for businesses running a mix of petrol, diesel and electric vehicles. With operating costs already under pressure, fleet managers will need to look beyond the initial cost of buying or leasing a vehicle and pay closer attention to the overall cost of running it efficiently.
Rising costs: What are the biggest Budget changes for fleets?
Although some measures offer short-term support, others will have a longer-term impact on fleet spending.
Here are the key changes businesses need to be aware of:
Fuel duty: Relief for now, but a bigger bill ahead
The 5p-per-litre fuel duty cut has been extended until July 2027. This helps to keep fuel costs down (though certainly not low) in the short term. However, when the temporary reduction ends, fuel duty increases in line with inflation. Operators could see fuel prices rise by around 9p per litre, including VAT. For businesses running large diesel and petrol fleets, particularly those covering high mileages, this could make a noticeable difference to annual running costs. It also makes fuel efficiency and driver behaviour even more important.
Capital allowances: What does the change mean for businesses buying vehicles?
From April 2027, the main writing-down allowance will reduce from 14% to 12%. In simple terms, this is a form of tax relief that allows businesses to deduct part of the value of qualifying assets from their taxable profits over time. The Budget also increases the main first-year allowance from 40% to 50% for qualifying expenditure from January 2027, while retaining full expensing for eligible investment.
The important point for fleet operators is that the tax treatment depends on the type of vehicle and how it is purchased. Not every vehicle qualifies for the same allowances. Businesses considering outright vehicle purchases should therefore look at the full financial picture. This includes the available tax relief, rather than assuming that leasing will automatically be the cheaper option.
Electric vehicle road charging: A new cost from 2028
From April 2028, Electric Vehicle Excise Duty (eVED) will introduce a mileage-based charge for eligible electric and plug-in hybrid vehicles. The rates are set at 3p per mile for fully electric vehicles and 1.5p per mile for plug-in hybrids. For example, an electric vehicle covering 25,000 miles a year could attract an additional £750 in annual charges if the full 3p rate applies. This means businesses need to consider mileage and vehicle usage when calculating whole-life costs. Whilst electric vehicles can still potentially offer savings in areas such as energy and maintenance, the financial benefits need to be assessed realistically.
Benefit-in-Kind: Company car costs will continue to rise
Company car BIK rates for fully electric vehicles will increase gradually, reaching 10% by 2030/31. Although electric company cars will continue to benefit from favourable tax rates compared with many petrol and diesel alternatives, the annual increases will need to be factored into employee benefit and salary sacrifice schemes. Employers should review their company car policies and make sure both the business and employees understand the longer-term costs.
Is it time to rethink leasing and buy vehicles outright?
With so many changes affecting fleet costs, now could be a good time for businesses to reconsider how they acquire their vehicles. Leasing has traditionally been an attractive option because it avoids the need for a large upfront investment and offers predictable monthly payments. However, those payments are an ongoing expense, and at the end of the agreement, the business has no vehicle asset to show for it.
Outright purchase is a different proposition.
Buying vehicles requires a substantial upfront investment. Businesses must either tap available cash reserves or secure financing, weighing these costs carefully against other capital priorities. However, the long-term benefits make ownership an attractive strategy.
When your business owns its fleet, you gain direct control over service life, replacement timelines, and resale methods. You eliminate lease mileage restrictions and end-of-contract penalty fees, while retaining residual equity when you sell each asset. Ownership also grants operational flexibility: instead of locking into rigid lease terms or arbitrary turnover cycles, you make upgrades based on each vehicle’s real-world condition, performance, and operating costs.
Of course, ownership also means taking responsibility for maintenance, repairs, depreciation and disposal. These costs need to be properly managed, and the decision should always be based on a comparison of the full whole-life cost rather than simply the purchase price against a monthly lease payment. At Fleet Service GB we have some convincing statistics to show that unbundling maintenance from lease arrangements can represent significant cost savings.

This is where Fleet Service GB’s unbundled approach to fleet management comes in.
Businesses don’t have to choose between owning their vehicles and having someone manage the day-to-day running of their fleet. By separating vehicle ownership from fleet management, organisations can retain the benefits of owning their assets while using Fleet Service GB’s expertise to manage maintenance, repairs, accident management, driver risk and vehicle disposal. Our work with Platform Housing Group is an example of how moving away from traditional leasing towards outright vehicle purchase. Allowing a more flexible fleet management model can deliver financial benefits. With the Budget likely to put further pressure on operating costs, businesses should be asking themselves whether continuing to lease is really delivering the best value over the lifetime of their vehicles.
Could higher mileage allowances increase grey fleet risks?
Another change in the Budget is the decision to make the 55p-per-mile tax-free business mileage allowance permanent for the first 10,000 miles, with the rate for additional business mileage increasing from 25p to 35p from April 2027. Whilst this is welcome news for employees using their own vehicles for work, it could create additional challenges for employers. Higher mileage payments may make using a personal vehicle more attractive than taking a company car or van. This could potentially lead to an increase in grey fleet use, where employees use their own vehicles for business journeys. The issue is that employers still have a duty of care towards employees driving for work, regardless of who owns the vehicle.
Businesses need to make sure that:
- Vehicles are roadworthy and properly maintained.
- Drivers have valid MOT certificates and appropriate business-use insurance.
- Driving licences are checked regularly.
- Drivers understand their responsibilities and follow company driving policies.
- Vehicle checks and driver behaviour are monitored wherever possible.
Without the right checks in place, businesses could find themselves exposed to unnecessary risks, compliance issues and additional costs. A robust driver management process, including regular licence checks, vehicle document validation and digital vehicle inspections, can help employers stay on top of their responsibilities.
Why controlling maintenance costs will become even more important
With fuel costs potentially rising, new mileage charges on the horizon and changes to capital allowances, fleet operators will need to find savings wherever they can. One area worth looking at closely is Service, Maintenance and Repair (SMR) spending. Maintenance costs can quickly get out of control if repair quotes, labour rates and replacement parts aren’t properly checked. Unnecessary repairs, inflated workshop charges and vehicles spending too long off the road can all have a significant impact on the bottom line.
For businesses that own their vehicles, keeping on top of maintenance is particularly important. The longer a vehicle remains in good condition and performs reliably, the more opportunity there is to get value from the original investment. This is where having greater control over maintenance management can make a real difference. At Fleet Service GB, we take a hands-on approach to managing vehicle maintenance. Rather than outsourcing repair authorisations, every repair quote, service requirement and tyre replacement is reviewed by the FSGB Garage Network.
This means we can challenge:
- Workshop labour rates and the time charged for repairs.
- Parts and components being replaced earlier than necessary.
- Repairs that may not meet manufacturer recommendations.
- Long workshop waiting times that keep vehicles off the road.
By keeping control of the process, we help businesses avoid unnecessary spending, reduce vehicle downtime and keep their fleets running efficiently. Our approach can deliver immediate savings of 10% to 15% on routine SMR invoices, helping operators make better use of their maintenance budgets.
Using data and technology to keep fleet costs down
The Budget changes make it even more important for fleet operators to understand exactly where their money is going. Fuel waste, poor driving habits, preventable accidents and unnecessary vehicle damage can all add significant costs to a fleet. But these issues are often difficult to identify when information is spread across different systems and spreadsheets. Having everything in one place makes it easier to spot problems, understand what’s driving costs and take action before they become bigger issues.
Fleet Service GB’s Achieve Software Hub brings together information from across the fleet, including:
- Telematics data, such as speeding, idling, harsh acceleration and braking.
- Vehicle maintenance and repair history.
- Accident and incident information.
- Daily digital vehicle checks through the Achieve Driver App.
By bringing this information together, fleet managers can get a much clearer picture of how their vehicles are being used and where improvements can be made. For example, identifying drivers who regularly brake harshly or accelerate aggressively can help businesses provide targeted training. This can reduce fuel consumption, tyre wear and the likelihood of accidents. The benefits of this approach can already be seen across the fleets of our existing customers.
LiveWest: Growing the fleet while reducing costs
Working with Fleet Service GB, housing provider LiveWest increased its fleet from 210 to 514 commercial vehicles, a growth of 144%, while reducing crash repair costs by 36%. The partnership also delivered:
- A reduction in insurance claim frequency from 17% to 6%.
- A 13% reduction in driver-related maintenance costs.
- A 16% reduction in total fleet mileage.
- Annual savings of £86,571.
Canal & River Trust: Saving £250,000 through better fleet management
Our work with Canal & River Trust delivered £250,000 in direct savings. By bringing incident management and driver monitoring together, the organisation achieved:
- A 30% reduction in collision claims.
- A 19% reduction in at-fault incidents.
- A 21% reduction in non-fault incidents.
- A 12% reduction in fuel spending through better use of telematics.
- A 20% reduction in overall year-on-year fleet expenditure.
These examples show that even when external costs are difficult to control, there are still opportunities to make meaningful savings through better fleet management.
What does the 2026 Budget mean for the future of the fleet industry?
The 2026 Budget presents a challenging few years for fleet operators. Whilst the extension of the fuel duty cut offers some breathing space, rising BIK rates, the introduction of eVED and changes to capital allowances will all need to be factored into future fleet budgets. For businesses, it is a good time to look beyond the immediate cost of acquiring vehicles and consider the bigger picture.
Leasing may appear more affordable because it spreads the cost into manageable monthly payments. However, businesses should also consider what they are paying over the full term, what they own at the end and whether they are missing opportunities to retain value from their vehicles. Buying outright requires more capital upfront, but it can provide greater long-term control and flexibility. When combined with effective maintenance management, careful vehicle replacement planning and a proactive approach to driver risk, ownership can offer a compelling alternative to traditional leasing.
Ultimately, fleet operators have little control over Government tax decisions or fuel prices, but they do have control over how efficiently their vehicles are purchased, maintained and managed. At Fleet Service GB, we believe businesses should be looking at the bigger picture: owning their vehicles where it makes financial sense, managing them more effectively and making every asset work harder for longer. The Budget may bring additional costs, but it also provides an opportunity to rethink traditional fleet management models and find smarter ways to protect the bottom line.
