Hi Gaz,
I've got the perfect solution, mate. I have spare, probably just under 1m, of PCOCC-A Furukawa/Oyaide mains cable, as shown here:
https://tm3connections.com//index.ph...de-eefs2-cable, which I use on all my mains leads, and indeed forms the base cable for the MCRU 'Ultimate' mains lead, shown here:

You could of course, if necessary, cut it down to 0.5m.
This is genuine top-notch mains cable, Gaz, and due to its construction (if you read the blurb) pretty much unbeatable in the application you're intending. The cable I have is also fitted with a Rhodium version of one of these Furutech 13A plugs :

The other end of the cable, however, has bare wires and would need an IEC plug fitted. However, if you want it the cable 'as is' with the Furutech 13A plug, I could do it for very good price (mates rates). Just PM me if you're interested
In terms of quality double sockets, I'd got for one of these, as I've used them before and they're superb, not stupidly priced either:

If you want maximum SPPV, that's where it's at. They're the 'audiophile wall socket' equivalent of the Monoprice HDMI cables!
Marco.
