I (carefully, and having read a lot about consumer units first) swapped the two identical RCDs
.
The LED bulbs weren't suspects, two plug sockets and perhaps a loose connection or other issue in the consumer unit were.
I couldn't work it out so I got a sparky in - he tightened everything up in the CU and that seemed to fix it (without even turning the power to it off, lol) but he also sorted out our two faulty plugs. He was great and it cost me £40 which seems insanely low!
