What connection is needed for dishwasher - plug (with extension) or fused socket?

Hi, You need to be able to isolate before you move it (for maintenance etc.). You can do this by plugging it in the socket as you have already suggested. If you want to have an aesthetic worktop i.e. you do not want to see the cable, you can install a socket in an accessible position so that you can still isolate prior to removal, sometimes an adjacent cupboard will suffice. You only need a fused spur when you are placing a socket out of reach, this has two functions, safe isolation for maintenance and to fuse down for a single cable (spur) to the socket. All works in a kitchen by law are reportable to local building control (a Part P registered business can do this on your behalf).

Requirements for Part P have changed - All works within a kitchen are not required.
