Vauxhall are able to get charge cables but not sure of cost. My problem has been the cable length. I am currently waiting for charge points to be installed at my office. I have to plug my Ampera in through my window but with such a short cable I used an extension cable but after just 1 hour the trip went. It took over an hour to cool down so not great. I needed a solution. I have the same problem at home so I contacted a supplier to make me up an extension set. They did a great job, plug, extension cable, circuit breaker and then the other end has a spike to go into the ground with a waterproof outdoor socket. It works great and all of this for £160.00 + VAT. Anyone wants more details. Let me know.
