Battery electric cars took 29.8% of the UK new car market in August 2026, and fleets accounted for 57.2% of all new car registrations. If your business has drivers on the road every day, the big question is how to transition a fleet to electric without disrupting the services that depend on it. 

A phased, data-led plan is the safest route, and it's the thinking behind eStart, our EV transition planning service.

At a glance

• Battery electric cars took 29.8% of the new car market in August 2026, with fleets driving most registrations.
• A phased rollout keeps business-critical company cars on the road throughout the switch.
• Driver surveys and EV champions build confidence before the first cars arrive.
• Parking, council rules and real journey data decide which drivers switch first.
• Regular feedback on range and charging turns early adopters into advocates for the wider fleet.

The right transition plan starts with your drivers, sites and lease end dates. Find out how eStart works or speak to our team about your fleet.

How to transition a company car fleet to electric without disruption

Momentum is building, but unevenly. Across the first eight months of 2026, battery electric cars made up 25.6% of new car registrations. That’s a distance short of the ZEV mandate's 33% headline target for the year.

Time and again we hear that charging access is one of the biggest hurdles: around four in ten UK households have no off-street parking, so a driveway charger is out of reach for many company car drivers.

For people in your company like field sales, engineering and service teams, a car off the road directly translated into missed appointments and lost revenue. Obviously when you think about swapping the whole fleet on one date, that puts that at risk, so you need a phased plan built around existing lease end dates. That way you can move the right drivers first and learn as you go. It’s not as complicated as it sounds, and at SG Fleet we’ve broken it down into four steps.

Step 1: Engage your drivers early

Start with the people who'll drive the cars. A simple workforce survey is a good way to raise the practical issues early: where drivers park overnight, how far they travel on a typical day and what concerns them about going electric. Range, charging time and who pays for home electricity tend to come up most; each is easier to resolve before an order is placed.

Find your EV champions

Use the survey to spot drivers who could be keen to adopt early. Think about giving them a demo car to trial during a normal working week, then ask them to share what they learn with colleagues. Short lease and rental offers a low-commitment way to put electric cars in drivers' hands before a wider rollout.

Step 2: Build your EV fleet transition plan on data

Pull together everything you know about your drivers into a single view and you start to see where the plan takes shape.

Charging a company car at home

Record which drivers have off-street parking, then confirm a home charging partner and the cost of installs so you can budget accurately.

Appoint a third-party provider to handle reimbursing drivers' home energy costs. HMRC's Advisory Electricity Rate for fully electric company cars is currently 7p per mile for home charging and 15p for public charging, and reimbursing business mileage at or below these rates creates no taxable profit or Class 1A National Insurance.

HMRC reviews the rates quarterly, so check the latest figures before setting your policy.

EV charging without a driveway

For drivers who park on the street, check each council's position on cross-pavement charging. The government has confirmed a new permitted development right for cross-pavement solutions in England, which will remove the need for a separate planning application once legislation is in place. Councils will still oversee each installation through highways consent, so local policy matters.

Match range to real journeys

Review each driver's typical mileage and journeys to choose the right EV range, then map average journeys against public chargers. Drivers who can charge at home and whose routes are served well by the public network are the most obvious candidates for the first batch.

Step 3: Deploy your first electric cars

Now you’ve got the data in place, deploy the first batch of cars to the drivers best placed to succeed. Issue each driver an energy card for public charging so they're never paying out of pocket on the road, and make sure you walk them through how it works before collection day.

For home charging, drivers can just send their electricity bills to the reimbursement provider, which works out and repays the cost of charging the company car.

Top tip: Keep the process simple, because a fiddly claims routine quickly erodes goodwill.

Phasing deliveries around lease end dates means each batch builds on the last while your operations keep running.
