The power company here doesn't really have any juristiction past their meter anymore. They could cut the power if they felt there was a clear and immediate danger to the property or if your installation was causing problems to the network.
They will refuse to energise or reenergise a supply where things are not up to code though. i.e. they normally require compliance certificates and will visually inspect the inside of the distribution panel (consumer unit), check the polarity of a few random circuits etc...
