Moving a taxi fleet to electric: costs, charging and grants

An electric car is only cheaper to run than a diesel if you charge it in the right place. This guide sets out what councils now ask for, which clean air zones charge taxis, which grants are open in October 2026 and which have closed, what charging really costs per mile, and how to move your fleet across car by car rather than all at once.

Do councils require electric taxis?

Some councils already require zero emission capable vehicles for new licences, and more set emissions rules that push you that way. Your council's vehicle policy sets the timetable for your fleet, so read it before you buy anything.

Two examples show how far apart the rules can be:

For London private hire, zero emission capable means no more than 50 g/km and at least 10 miles on zero emissions, or no more than 75 g/km and at least 20 miles. Check the official CO2 and electric range figures for any plug-in hybrid before you buy it.

Watch the age limits as closely as the emissions rules. The Department for Transport's best practice guidance for councils says age limits can be counterproductive, and points out that "a 5-year-old used electric vehicle will produce less emissions than a new Euro 6 diesel or petrol car". If your council still sets a strict age limit, a used electric car might not be licensable, however clean it is.

Which clean air zones charge taxis?

GOV.UK lists seven clean air zones in England, and all seven charge taxis and private hire vehicles that don't meet the standard:

In Bristol, a non-compliant taxi pays £9 a day. Petrol cars to Euro 4 and diesels to Euro 6 avoid the charge, and fully electric vehicles are exempt. A zone charge is one more cost an older diesel carries that an electric car doesn't. Example: £9 a day on a car working six days a week is £54 a week (£9 × 6).

What grants are there for electric taxis in 2026?

Fewer than there were. The grant built for taxis has gone, and what's left is aimed at cars, wheelchair accessible conversions and chargepoints.

The plug-in taxi grant is the one most people ask about, and it has closed. In February 2024 the government said it had put more than £50 million towards over 9,000 zero emission cabs, at £6,000 a vehicle. In February 2025 it cut the grant to £4,000 for another year. Since 1 April 2026 the government's grant pages and its dealer portal cover cars, vans, trucks and wheelchair accessible vehicles only.

The Electric Car Grant is the main help now. GOV.UK says it's available to private individuals and businesses buying or leasing an eligible car at the point of purchase, and that you don't apply: the seller includes it as a discount. Since 17 July 2026 every order has to be registered to a named individual, the end customer, so ask the dealer how a car bought in your firm's name will be registered. Eligible cars need a battery warranty of 8 years or 100,000 miles. A busy taxi can pass 100,000 miles well inside 8 years, so read the warranty terms for high-mileage use before you rely on them.

How much does it cost to run an electric taxi?

Charged at home, an electric car can cost well under half as much per mile as a diesel. Charged at rapid chargers, it can cost more than diesel.

Example, per 1,000 miles, using October 2026 prices: diesel at 199.52p and petrol at 174.88p a litre (government weekly figures for 5 October 2026), home electricity at 26.32p per kWh (Ofgem's price cap for October to December 2026), and public charging at 54p and 79p per kWh (Zapmap's September 2026 averages). The economy figures are examples too: use your own cars' real numbers.

The lesson is in the bottom row. A driver who does all their charging at rapid chargers pays more per mile than a diesel driver, so where your drivers charge matters more than which car you buy.

Tax is changing too. An electric car pays £10 of vehicle tax in its first year and the standard rate of £200 a year after that, plus £440 a year for 5 years if its list price was over £50,000. From 1 April 2028, Electric Vehicle Excise Duty adds a mileage charge of 3p a mile for battery electric cars and 1.5p for plug-in hybrids. Example: a car doing 40,000 miles a year would pay £1,200 (40,000 × 3p). The government's document doesn't single out taxis, so check how it applies to licensed vehicles nearer the time.

If the firm buys the cars, GOV.UK's capital allowances guidance says new and unused zero emission cars qualify for 100% first-year allowances, so the full cost can be claimed against profits in the year you buy. Ask your accountant how that fits your own accounts.

Where will your drivers charge?

At home if they can, because that's where the sums work. Ask every driver before you choose a single car.

• A driveway at home costs least per mile, on a domestic tariff.
• A flat or a rented home can get up to £500 towards one socket from the chargepoint grant for flats and renters, open until 31 March 2027.
• A home with on-street parking has its own £500-a-socket grant, on the same terms.
• Your office or depot can get up to £500 a socket under the Workplace Charging Scheme, which is open to businesses, for up to 40 sockets across your sites.
• Public rapid chargers are for top-ups. TfL says rapid and ultra-rapid chargers can give an 80% charge in as little as 20 minutes.

Twenty minutes on a charger is twenty minutes off the road, and on a Friday night that's a job or two. Plan charging around your taxi busy periods, not in the middle of them.

Settle who pays for what. If drivers own their cars, charging is their cost. If you rent cars to drivers, the rental agreement should say who pays for the electricity and any depot charging.

Should you switch the whole fleet at once?

No. Switch car by car, as licences come up for renewal and cars reach your council's age limit. You'll learn the real range, charging times and costs on a few cars before you commit the rest.

A sensible order:

1. Drivers who can charge at home, on town work.
2. Cars that need replacing soonest under your council's age limit.
3. Airport and long-distance work, once you know the real winter range.
4. Wheelchair accessible vehicles last, because the choice is narrower: the grant's list had seven eligible converted models when we checked.

Owner-drivers decide for themselves, and you can't make them change cars early. Show them the cost per mile with their own figures, and the council's policy will settle the timing at replacement anyway. Our guides to choosing vehicles for a taxi fleet and the cost of starting a taxi business cover the wider choice.

How do you plan the move to electric?

Take it in this order, and give it a season before you judge it.

1. Read your council's vehicle policy and the clean air zone rules where you work.
2. List every car with its licence expiry and the date it hits the age limit.
3. Ask each driver where they'd charge, and note who has a driveway.
4. Price two or three eligible models with the dealer, with the grant taken off.
5. Get insurance quotes for the exact model before you buy.
6. Apply for depot chargers under the Workplace Charging Scheme before it ends on 31 March 2027.
7. Track the cost per mile on the first cars for three months, including any time lost charging.
