I know that if an electrical connection is to be plastered over it must be
crimped or soldered.

No electrical wire or connection should be plastered over.

Could someone please provide a link to a suitable joining piece (either
crimp or solder).

Put it in a conduit, either metal or plastic, so it can be withdrawn.

My screwfix catalogue seems to only show standard crimp connections.

Then you should avoid Screwfix like the plague.

Any advice on regulations regarding this type of joint would also be
helpful.

See above!

Alan


Thanks
