What to do? Sparky put socket in wrong position

Need some advice please!

This piece of s**t project has cost me my sanity and I'm at my wits end - everything that could go wrong, has. And to top things off, just made this discovery.

I really don't want to have to rip out tiles, hack-out parts of the wall to get the sparky to re-do the socket. (I really cannot overstate how badly I don't want to go back so many steps - I've lived without a kitchen for almost a year now).

Does anyone have any ideas? I can't find any other hoods that have 305mm chimneys (so the socket would fit within) - does anyone know of any?
