I’d go with a wago box, or any other maintenance free junction box.
The minor issue is that you’re unlikely to have the tools or equipment to be able to check that your repair is ok - if done properly it will very likely be fine, but just a heads up.
Ah yeah deffo. And FWIW I'd almost guarantee that most sparks would perform the same repair and not end to end test it.
If you show them your repair I’m sure they be happy with it.
Have you got any slack on the cable btw?
