I have to extend the cable feeding 13A sockets. Is this:

'maintenance free'? Or should I use a junction box. The cable will be
underneath floorboards, routed properly.

And apologies - I'm sure I've seen this raised before - but I can't find

If the floorboards are liftable, you could arguably use a regular
junction box. However, bearing in mind that people lay carpets and
laminate over the top, I'd use one of these:

Maintenance free, cable clamps and fixing of the box by screws to the
joist - everything you need in one box at a dirt cheap price. I have
used these BTW and they are good.
