As above, those cables should not be moved at all, they can be particularly dangerous if abused due to the enormous power behind them.
Your best plan is to think of boxing the lot in with some simple wooden arrangement, etc. But it must be accessible as the black box thing at the bottom is the cut-out where the main fuse for your property resides. Again, that should not be tampered with, but sometimes there is the need for it to be removed to isolate the supply for any work on the billing meter or the supply to your CU (consumer unit = fuse box).
Finally what is not obvious is the CU which I presume is just out of the photo and above the meter?
If it is an old rewireable fuse style you ought to think of replacing it, and be aware that modern replacements are significantly bulkier so if planning an overall box you should consider that future size use at this point in time.
