Tesla has opened new 'supercharger' locations in London and Birmingham, part of a rapid network expansion that it says will soon allow UK Model S owners to drive anywhere in the country and charge for free, for life.

The first new 'supercharging' site is located at Hyatt Regency London – The Churchill, in Portman Square.

The 'supercharger' can be accessed in the hotel car park, which will be free to Model S owners for one hour while charging.

With valet parking available, it is the first 'supercharger' in central London and represents the first step in Tesla’s inner-city charging strategy for the UK.

Such centrally located chargers will allow customers who don’t have access to off-street parking or personal garages to easily find charging options close to home or work.

The second site is at the Hyatt Regency Birmingham, on Bridge Street. As well as allowing Model S owners to charge upon arrival in Birmingham, the site enables electric travel to the Midlands and beyond.

“This Birmingham location signifies our first move out of London in recognition of the fantastic support in the area,” said Georg Ell, Tesla’s UK country director.

“We will open a store in coming months offer Midlands-based Model S owners a convenient local service.

“Both Hyatt Regency hotels offer a great base for Model S owners whilst charging. With everything from bars and restaurants through to business centres and gym facilities, there is plenty to keep you occupied for your 30 minute charge.”

A 'supercharger' replenishes half a charge in about 20 minutes. Sites are strategically placed along well-travelled routes to allow Model S owners to drive long distances with minimal stops.

They are located near amenities like motorway services, restaurants, cafes and shopping centres so drivers can stop for a quick meal and have their Model S charged by the time they’re done, says Tesla.

Tesla has installed 168 'superchargers' worldwide.
