Vehicle costs are one of the largest outgoings for many UK businesses, so this is an area that is ripe for savings. The good news is that cutting business vehicle costs often goes hand in hand with lower emissions and less air pollution. Whether you run a single car or a small fleet, a regular cost review will help you spot where money is being wasted. Here are five practical ways to reduce your business vehicle costs in 2026.
1. Review your insurance cover
Business vehicle insurance is an area where savings are often hiding in plain sight. Start by checking the level of cover. A fully comprehensive policy with unlimited mileage may be overkill if the vehicle only covers a few thousand business miles a year. Make sure the policy accurately reflects the class of use, whether that is commuting, business use or commercial travelling, and that you are not paying for cover you do not need.
Loyalty rarely pays in the insurance market, so compare quotes at renewal rather than auto-renewing. If you operate several vehicles, a fleet or multi-vehicle policy can be cheaper and easier to manage than separate policies taken out at different times. Some insurers also offer telematics or pay-as-you-drive policies, which can cut premiums for low-mileage or careful drivers. The British Insurance Brokers’ Association can help you find a broker who understands commercial motor cover.
2. Consider electric or low-emission vehicles
Switching to an electric van or a low-emission car can cut fuel, tax and running costs significantly. Electric vehicles have fewer moving parts and lower servicing bills. From April 2025, DVLA rates for 2025/26 moved zero-emission cars onto the standard rate of £195 a year and zero-emission vans onto the light goods vehicle rate of £335 a year. Even so, the running-cost advantages remain strong, especially if you can charge at home or at work on a low overnight tariff.
Be aware that government plug-in grants have closed. The plug-in car grant ended in June 2022, and the plug-in van and truck grants closed to new applications in April 2025, the Department for Transport confirmed. Support for chargepoint installation may still be available through targeted schemes, so check gov.uk for the latest before you budget.
You should also factor in clean-air and low-emission zones. Transport for London’s Ultra Low Emission Zone covers all London boroughs and charges non-compliant cars, vans and motorcycles £12.50 a day. Birmingham, Bristol, Bradford, Sheffield and Newcastle operate Clean Air Zones that can charge cars and vans between £7 and £12.50 a day. Portsmouth’s Class B zone charges larger vehicles such as HGVs, buses, coaches and taxis. Scotland has Low Emission Zones in Glasgow, Edinburgh, Aberdeen and Dundee; Transport Scotland says entering a non-compliant vehicle brings a £60 Penalty Charge Notice, reduced to £30 if paid within 14 days.
3. Downsize or reduce mileage
Do you need a large van or estate car for every journey? Smaller, lighter vehicles use less fuel, sit in lower vehicle tax bands and are usually cheaper to insure. If you regularly drive into congestion or clean-air zones, the savings from a smaller or cleaner vehicle are even greater.
Remote meetings and home deliveries have become normal since the pandemic. Before setting off, ask whether the trip is necessary. Could the meeting be a video call, or could goods be couriered instead? If you only need occasional access to a car, a car club such as Enterprise Car Club or Zipcar lets you hire a vehicle by the hour, while many towns offer bike and e-scooter hire schemes. For solo urban journeys, public transport, cycling or an e-bike can be far cheaper than running a car.
4. Drive more efficiently
Fuel is a major vehicle cost, and driving style has a big impact. Keep your vehicle well maintained: under-inflated tyres, dirty air filters and overdue services all reduce fuel economy. Remove roof racks, roof boxes and unnecessary loads when they are not needed; they increase drag and push up fuel consumption.
On the road, drive smoothly. Accelerate gently, change up through the gears promptly, and anticipate traffic so you can avoid harsh braking. Stick to speed limits; for many vehicles the most fuel-efficient speed on faster roads is around 50 mph. Air conditioning and heating use engine power, so use them sparingly and dress for the weather where safe to do so. The RAC publishes detailed fuel-saving guidance for drivers.
5. Cut business vehicle costs through tax-efficient finance
The most tax-efficient way to fund a business vehicle depends on your business structure and how much the vehicle is used for personal journeys. You can read more about the wider tax picture in our guides to allowable expenses for the self-employed, Self Employed Tax UK and sole trader vs limited company structures.
If you are a sole trader or partner and use your own car, van or motorcycle for business travel, you can claim HMRC’s approved mileage allowance payments for the 2025/26 tax year: 45p per mile for the first 10,000 business miles each tax year, and 25p per mile thereafter. Motorcycles can be claimed at 24p per mile and bicycles at 20p per mile. Alternatively, you can claim the actual proportion of vehicle costs, but you cannot mix the two methods for the same vehicle. See the latest HMRC simplified expenses guidance for full details and keep a record of every business journey.
If you run a limited company, you can buy the vehicle outright or lease it. From April 2025, HMRC ended the 100 per cent first year allowance for new electric cars. Cars are now pooled for capital allowances according to CO2 emissions: those with emissions of 50g/km or less go into the main rate pool at 18 per cent a year, and those above 50g/km go into the special rate pool at 6 per cent a year. Vans are treated as plant and machinery, so a limited company can usually claim the Annual Investment Allowance, which gives 100 per cent relief on qualifying spending up to £1 million a year.
Leasing payments are usually fully deductible as a business expense, though HMRC applies a 15 per cent restriction on lease rental deductions if CO2 emissions exceed 50g/km. Running costs such as insurance, servicing and tyres can also be claimed, but if the vehicle is available for private use it will trigger a benefit-in-kind charge for the employee or director.
For company cars, HMRC publishes quarterly Advisory Fuel Rates for petrol, diesel and LPG vehicles, and an Advisory Electricity Rate for fully electric cars, set at 9p per mile from June 2025. Reimbursing employees at these rates avoids tax and National Insurance complications. Keep detailed mileage logs to support any claim.
Cutting business vehicle costs is not usually about one big change; it is about reviewing insurance, vehicle choice, mileage, driving habits and tax treatment together. Many of these steps also cut emissions and air pollution, which is good for your brand as well as your bottom line. If you are unsure about the tax implications of a vehicle purchase or lease, speak to a qualified accountant before you commit.
Next steps to take
- Check your insurance class of use and compare quotes before auto-renewing.
- Calculate the total cost of ownership for an electric or low-emission vehicle, including VED, benefit-in-kind and clean-air zone charges.
- Audit your business mileage for one month and replace unnecessary trips with video calls, courier services or public transport.
- Service your vehicles and check tyre pressures to improve fuel economy.
- Review your capital allowances, mileage claims and benefit-in-kind position with an accountant before your next vehicle purchase.
