Move Socket 2 Feet - Acceptable to Join Cables In Old Wall Box?

[ReganAndCarter]

I need to move a double wall socket 2 feet to the left. Existing socket is on a metal back box sunk into block wall. If I sink a new box for the new socket, can I join the two 2.5 mm ring main cables in the old box using Wago or 32A push in splice connectors to two new lengths of 2.5mm? These two new lengths of 2.5mm will run in a chase horizontally from old box to the new box for new socket. The old box will be retained and covered with a blanking plate for access to connectors if needed.

The socket needs moving because it's in the wrong place behind new tall kitchen cabinets and will interfere with drawers in the cabinet. The socket will be used for fridget and oven.

Just wanted to check what I'm doing is acceptable. Thanks for any help or advice.

My electrician did exactly that, although used a Wago box to join everything. I've now plastered over the old box position. You have to be careful though about 'spurs off-of spurs' etc. I'm no electrician and so can't advise. With ours he had to re route some supply cable from the back or something. I didn't really understand it tbh, just asked, "can it be done or not?"
