Small electrical job removing a wall outlet and making a new one (kitchen)

We are having a custom cupboard mounted in the kitchen (see attached image). This will mean that we will have to remove a 4-plug wall outlet. Seeing as this space was previously occupied by a hot water tank, there is an electrical unit which we're not sure needs to be there anymore. We would like to re-route this around the back of the new cupboard and out again so that we can have a new double (or single, not 100% sure yet) plug outlet to power a wall mounted vacuum cleaner charger (see attached image with green/red annotation indicating removing / adding). Additionally, if possible and technically allowed (as it's near the sink), we might want an extra single outlet on the right side of the the new cupboard, either below or above the light switch. It would be great if you could come prepared with 2x single outlets and one double for discussion. (elektriker)
