Please remember, you can plug this system into any 13amp UK standard socket, so if you have one accessible in the garage or shed, that will be fine. Alternatively, we sell a range of good quality exterior rated sockets that is worth considering. I am sure a local electrician would not charge much to install one for you. You may wish to consider the RCD protected version. This will also cover you from potential electrical shocks when using any outside power devices such as lawn mowers.
