You have little to no chance of them moving it now, If you were in the electrical 1st fix stage you might of had a chance, but you seem to be in the 2nd fix stage and it would require them ripping ceilings down etc. I'm willing to bet your electric meter is going to be directly below in the car Port and this was the best place electrically for the consumer unit. Placing it in the hall would require a long run of the mains tails which isn't great.
