For British Gas, it’s the third such manufacturer partnership, and follows preferred supplier deals with Renault and Nissan, making it the preferred choice for more than 70% of the UK electric vehicle market in 2012.

Toyota customers will be offered a range of services and products designed to make home charging as safe, efficient and convenient as possible, including free site surveys and advice, and installation of charging points starting from £275 for a three-pin socket with its own circuit.

Purpose-built charging units start from £799, with finance options available to spread the cost and an optional British Gas Home Electrical Care package, with unlimited call-outs per year including parts and labour charges.

Business customers will be offered either post or wall-mounted charging points, both with double sockets, which will eventually allow fast charging of vehicle batteries in under an hour.

Dean Keeling, managing director of British Gas Smart Homes, said: ‘Electric cars are coming of age and this new partnership with Toyota is part of a continued drive by British Gas to make any type of electrically powered car simple, safe and more cost-effective.

‘Our national network of electrical engineers provides all the advice and expertise necessary to enable car owners to power their car safely and easily, and for less money.’

Jon Williams, Toyota GB managing director, said: ‘In order for our customers to maximise the benefits of Prius Plug-in Hybrid, and Toyota’s future electric vehicles, it is crucial that they have access to the appropriate charging infrastructure, and the right professional advice and support. British Gas has the experience, skills and resources to provide the high quality products and services Toyota owners should expect.’
