I need to put in 4 sockets in a shop, where the sockets are going is a 6mm radial from an old circuit, its on a 32a rcbo, can i pull this 6mm into a 4 pole isolator and run a ring out of it, iv looked through the regs and cant really find anything thats says i cant.

what you are describing is a so called lollipop ring, these are not prevented by the regulations but can be a nightmare to identify later.

A radial circuit can have as many outlets as you need so long as you are not overloading the cable. A 6mm2 cable with a 32A breaker is perfectly fine for plenty of socket outlets.
You would just find it a bit tight to get 2 6mm2 in one SO. But you could also drop the csa to 4mm and continue as a standard 32A 4mm radial.

(it is an unfused spur off a ring that can only be one outlet)

6mm s gonny be a tight fit check new sockets as some manufacturers are better than others for accomodating there is one on the market has 2 terminals at each connection but i cant mind the make for the life of me CLIK comes to mind tho

So is this what used to be done? 4mm to jb then Ring from there?
I was always under the impression that this was frowned upon?

Generally, yes frowned upon but not dangerous or against the regs, just inconvenient to test and check later. I do not think it was ever standard, (but I could be wrong)

I have seen lots of them in a university science department. They ran a 6mm to the labs, and then had a DP isolator. This then fed the ring. RCD protection was added in some labs, but not in others, due to experiments that could be ruined if the power was lost.

A lot of council and miners mansion housing back in the 60's was wired similar to this.

You would have a ring running around, and at every socket point the ring would go into a JB and then a single cable out to the socket, it was felt you used less cable which I suppose you did, easier chasing in a single cable rather than 2 cables and easier connecting into a socket.

Always threw me at first, but got use to it

UK Ring main or radial
Joining the ends of the radials together to form a ring, and changing the circuit protection to a single 32A would solve the MCB overload problem...
