Wiltshire is behind the curve on the green transport revolution with less than average access to electric car charging points, new figures suggest.

There were just 110 public charging devices in the county at the start of April, according to new Department for Transport data.

That means that in Wiltshire there 22 charging points per 100,000 people, leaving Wiltshire lagging behind the UK average rate of 27.

The area has added 14 new devices to its supply since the last count in October, when there were 96.

Across the UK, the number rose by 19 per cent over the six-month period to just under 18,000 in April.

Edmund King, president of the AA, said: “One of the myths we urgently need to clear up is a perceived lack in charging points.

“However, if drivers feel they cannot find a charge point then more needs to be done.”

He suggested that better signage for the devices could make them easier for motorists to spot, as well as finding solutions for those who want to charge their car at home but do not have off-street parking.

“Encouraging drivers to make the switch to electric cars will also encourage both councils and businesses to install charging infrastructure,” he added.

“We believe that further incentives are required to ease the transition to lower-emission vehicles, such as cutting VAT on the sale of certain vehicles or targeted scrappage schemes.”

The Daily Telegraph recently reported that Boris Johnson is considering launching plans to give drivers up to £6,000 to exchange their petrol or diesel car for an electric model.

Of the devices in Wiltshire, 16 were ‘rapid’ charging points, which can crank most electric car batteries up to 100 per cent in under half an hour.

There were 3,100 of these across the UK at the start of April.

The DfT data is sourced from the electric vehicle charging platform Zap-Map, which say it covers 95 per cent of publicly accessible devices.

Some units can only charge one car at a time, while others can deal with multiple vehicles simultaneously.

Across the South West, there were 1,397 charging devices – at a rate of 25 per 100,000, this put it fourth out of England’s nine regions for accessability.

Steve Gooding, director of the RAC Foundation, said the issue for drivers was less about the number of chargers and more about whether they work and are easy to use.

He added: “It’s high time connecting to a charge point proved no more challenging than pulling onto a service station forecourt to fill up with petrol and pay with your credit card."

A DfT spokesman said: “Accessing charge points has never been easier and we want to make it easier still, with a further £10 million to install chargers.
