A practical guide to moving your business vehicles to electric, from the first van to a fully electric fleet.
Government targets, manufacturer pricing, and running cost savings are all aligning at the same time.
The Zero Emission Vehicle Mandate now requires manufacturers to ensure 33% of new cars and 24% of new vans sold in the UK are fully electric in 2026. These targets rise every year, reaching 80% for cars and 70% for vans by 2030, with both hitting 100% by 2035.
For businesses buying or leasing vehicles, this means more electric models are available, pricing is becoming more competitive, and leasing companies are actively promoting EV options. Manufacturers who miss their targets face penalties of £15,000 per car and £9,000 per van, which creates commercial pressure to offer attractive deals.
At the same time, the running cost advantages of electric vehicles are well established. Lower fuel costs, reduced maintenance, road tax savings, and favourable benefit-in-kind rates all contribute to a total cost of ownership that increasingly favours electric over diesel and petrol.
Electric vehicle fleet management is becoming more straightforward as charging networks expand and telematics tools improve. There is a growing range of fleet solutions designed specifically for businesses transitioning to electric.

You do not need to replace every vehicle at once. Here is a practical approach for SMEs.
For an SME fleet of five to fifty vehicles, a phased approach is almost always more practical than replacing everything at once. The five steps below set out a sequence that works for most businesses.
List every vehicle: make, model, age, contract end date, average daily mileage, and typical route pattern. This gives you a clear picture of which vehicles are due for replacement first and which ones are candidates for an electric switch.
Vehicles with predictable daily routes under 150 miles, access to overnight charging at a depot or driver’s home, and upcoming contract renewals are your first candidates. Urban delivery vans, pool cars, and short-range sales vehicles typically fit this profile.
Arrange charging at your depot or office before the first electric vehicle arrives. The Workplace Charging Scheme covers up to 75% of costs. Run cable ducting to additional spaces during the initial installation to reduce future costs.
Align your electric vehicle switch with existing lease or contract end dates. This avoids early termination costs and spreads the transition over a natural replacement cycle. Most fleets can transition 60-80% of vehicles within two to three contract cycles.
After the first vehicles have been in service for six months, review the data: actual range achieved, charging patterns, driver feedback, and real running costs. Use this to inform the next phase of replacements and adjust your charging infrastructure if needed.
The areas where electric vehicles typically save money, and where they cost more.
Over a three to five year ownership or lease period, the running cost savings on fuel, maintenance, and tax often offset the higher upfront cost. For vehicles covering higher mileage, the break-even point comes sooner. We plan to build a fleet TCO calculator tool to help businesses model this for their specific vehicles. For SMEs without dedicated fleet managers, EV fleet management platforms can also help track charging, mileage, and costs across all vehicles.
The three main charging scenarios for business fleets, and how each one works.
Install chargers where vehicles are parked overnight or between shifts. Standard 7kW chargers are sufficient for most overnight use. The Workplace Charging Scheme covers up to 75% of costs. This is the simplest and most cost-effective approach for depot-based fleets.
If drivers take fleet vehicles home, they can charge overnight using a home charger. Employers can reimburse the electricity cost. Platforms like Rightcharge provide a single monthly invoice covering all driver reimbursements, removing the administrative burden.
For vehicles that cannot always return to base, public charging networks cover the UK’s major roads. Fleet charging cards from providers like Electroverse give drivers access to multiple networks from a single account, with consolidated billing for the business.
The key tax benefits available to businesses running electric vehicles.
Zero-emission vehicles qualify for full first-year capital allowances. The entire purchase cost can be deducted from taxable profits in the year of purchase.

Employees driving electric company cars pay just 4% BiK tax in 2026/27, compared to 23%+ for petrol and diesel. This makes electric vehicles significantly more attractive to employees.

Employers pay Class 1A NIC at 15% on the BiK value. A lower BiK value on electric vehicles means lower employer NIC costs. On a £40,000 car, the employer saves over £1,700 per year compared to a petrol equivalent.

Lease rental payments for zero-emission vehicles are fully deductible against corporation tax with no restriction. Petrol and diesel cars with emissions above 50g/km are restricted to 85% deduction.
