This is what Motability say…
If you are considering an electric vehicle you will need to have access to a charge point to recharge the battery and pay for the electricity that is used. There are two options available on the Motability Scheme. If you have off-street parking, you should be able to have a charge point fitted at your home. If this is the first charge point you have had installed, the cost of supplying and fitting the charge point will be covered partly by the Government’s ‘OLEV’ grantOpens in new window , which will be arranged on your behalf. We will then cover the rest of the installation costs, but if any work is required to gain access to your electricity supply you will be responsible for these costs. Please note that you can only receive an OLEV grant once, so if you have previously had a charge point installed which is not compatible with your next car, there will be a cost of £350 to fit a replacement.
