Britain's worst city for EV drivers has just eight charging points for 100,000 cars, a study has found.
Research compared the number of publicly available charging points to the number of registered vehicles in the area, rather than per capita.
Based on this benchmark, Sutton has 3,188 chargers per 100,000 registered vehicles, followed by Croydon at 2,175 and London at 353.
At the bottom of the table is Hereford, which has only eight chargers.
Areas such as Sutton, Croydon, London, Coventry and Edinburgh are all well prepared for the continued rollout of electric vehicles.
Other places such as Hereford, Derry, Inverness and Northampton may struggle to cope with growing EV numbers on the road, according to the research.

One of the teams involved in the investigation of One sure insurance policy told MailOnline: 'When considering switching to an electric vehicle, you should consider not only the availability of public charging points, but also how you will charge your EV from home.
'This is especially important for motorists who do not have a parking space at home.
'The availability of charging stations is an important factor that drivers take into account when deciding to switch to an electric car.
'If cities are not well prepared for the influx of electric vehicles, many motorists will not switch.'
Government spends £70 million to improve EV charging infrastructure to encourage more people to switch to battery-powered cars

The researchers used Zap-map.com to discover the locations of public EV chargers and compared them with vehicle registration data from the ONS.
Earlier this month, the government launched a £70 million pilot project to increase the number of ultra-fast EV charging points along the UK's motorway network.
The initial investment includes ten pilot locations and will cover part of the costs of upgrading the electricity grid to enable the installation of higher capacity charging units.
Transport Minister Mark Harper said: 'This Government stands on the side of drivers and working with the private sector to provide robust charging point infrastructure is part of our Plan for Drivers, with today's announcement paving the way for more ultra-fast charging points.
“This £70 million pilot project is the starting point and sends the message to consumers and industry that we are investing wisely and quickly to grow the future of transport in Britain.”
The Ministry of Transport added: 'Highway service areas are strategically important as regularly spaced stops along the motorway. The investments here address the need for a highly visible and reliable longer-distance charging network to support drivers and accelerate future EV purchases.
'The pilot, which is being delivered by National Highways, will help build evidence to support the design of a full fund.'

However, former BBC Top Gear presenter Quentin Wilson said the government must do much more to encourage wider adoption of electric cars – including changing tax rules that punish people who charge in public.
Mr Wilson, who set up a lobby group to represent EV motorists.
He said: 'FairCharge is the national campaign to help unlock the huge environmental, economic and social benefits of the electric revolution.
'FairCharge puts the critical issues of charging costs, infrastructure, air quality and availability of electric vehicles to the forefront of the political agenda.
'An important priority is to change government policy whereby EV drivers without home charging pay four times the VAT rate for their electricity from public networks on the street. Not only is this unfair, it's a policy mistake that experts say is slowing electric vehicle adoption. This VAT rule was written in 1994, long before electric vehicles first came onto the market.
'We also want measures to be taken so that lower-income motorists have access to electric vehicles and that the price of electricity is urgently decoupled from gas. This will help reduce the cost of charging an electric car at home, lower electricity bills for everyone and help move us towards more sustainable, independent energy.”
Former Top Gear presenter Quentin Wilson, pictured, has urged the Government to reform the amount of VAT paid by motorists using public EV charging stations, as they face a 20% VAT rate pay, compared to the 5% rate for domestic electricity supplies.
