External wall insulation and mains supply

ThisPete: 
 

I'm having external wall insulation installed on my house, and the mains supply to the house is via an overhead cable. The insulation installers have put the insulation over the mains supply cable, i.e. where it's clipped to the wall between bracket and meter box. The DNO is Western Power. 

My question is, is covering the mains PME cable with 90mm of insulation acceptable practice? 

Thanks, Pete

Hi Pete, welcome to the institute of enginering technologists forum,the pme earthing arrangement isn’t really relevant so rest easy on that one, if you could post a photo of your concerns they do paint a thousand words :)
