It is probably close to this - https://www.mains-cables-r-us.co.uk/...ower-lead.html but you won't get much detail from the listing.
Obviously, I don't have a UK plug, or fuse...
Personally, I don't care what people elsewhere may say. If mains did not make a difference, why do regenerators and balanced mains units exist?
I have DC on my mains, my amp hummed. I used a DC blocker and it went away. The DC blocker "protected" one piece of kit, so I went for a mains regenerator which protects the lot.
No humming toroidals = happy Cagey.
