Do you have access to replace that whole section of the ring, from socket to socket?

I do, but would have to remove a bunch of cladding. So fuck that noise.

Also - Ouch. Electricity terrifies me.

I found this when looking at extending a ring main using wagos, I imagine the theory can be extended to terminal blocks.

Yes, but a few points need to be observed to make sure it complies with BS7671 IET 17th Edition.
Firstly, the terminals must be installed in a Wagobox (when breaking into existing ring wiring). This needs to be UK sourced to ensure you get ones that are stamped with [MF], meaning that it's classed as BS 5733 Maintenance Free box.
To comply with the IET regulations, each Wagobox is limited to 50Amps in total. The compatible terminals, 773-10x(solid) and 222 (lever), are also derated to 20Amps (I prefer 221 as they're normally rated to 32Amps).
Therefore, for a regular 32Amp ring main, you will need to use two Wagoboxes - one at the start and one at the end of the extension. As the load from any socket is shared in both directions of the ring (albeit unevenly), the derated 20Amp terminals are sufficient.

I think I may have a couple of wago boxes around, and I definitely have some connectors. If not - screwfix here I come.

And a pointless little detail is that the wago box needs to be closed with a cable tie to fully meet the MF criteria (requires tooled entry).
