Vattenfall and NewMotion have signed a roaming agreement for the UK as a first step towards interoperability in the country.

Vattenfall says the tie-up will improve electric vehicles driver's charging options by offering access to more than 400 additional public power points around the UK via a single app or charge card.

"The era of electric transport is at a critical juncture and one of the things to make e-mobility fly is the ability of different charging networks and cars to work seamlessly together to make charging easy and efficient for customers," said Vattenfall VP E-mobility, Tomas Björnsson.

"The agreement with NewMotion is among the first of its kind in the UK, and an important step towards offering a hassle-free charging experience for UK drivers."

The supplier maintains the UK network is effectively 'closed,' with the market for charging infrastructure for EVs featuring very few roaming agreements.

Drivers of EVs need several apps and charge cards to be able to have access to charge points of different operators, while in other parts of Europe the networks are easily accessible with one charge card.

Currently there are around 25,000 public charging points in the UK, of which only a small minority are open to roaming agreements.

Vattenfall operates 14,500 charge points and is, together with partners, building inCharge, one of the largest power networks in Northern Europe.

NewMotion is a solutions company for electric vehicles in Europe and has installed more than 55,000 charge points across the region.

It is a member of the Shell group.
