Probably worth contacting the DNO, and if you can sending pictures in, so they can decide if they want to do anything about it.
In my experience with UKPN, unless there is anything obviously wrong or signs of heat damage they will likely give it a very low priority and nothing will happen anytime soon.
Guess you could go to the energy supply about meter tails, but again I imagine you will end up running around with little to any result...
