Ring main circuits appear to be radial at consumer unit.

The cable to the socket is indeed 2.5mm. All of the breakers for the sockets are 32A so you've got a dangerous situation there.

The cables look relatively new so I take that the cables for the sockets were changed as part of the rewire?

Carefully, remove the case of the consumer unit with the power off and show us a picture of the cable leaving the MCB for the sockets.

Or get a multimeter, remove the socket and measure the continuity from all of the conductors behind the socket (L to L N to N CPC to CPC) you should get a beep. Circuit should be powered off. I prefer this method.

Not much to be gained from showing us those pics I am afraid. A picture of the inside when you had the front cover removed would have been worthwhile showing to us ,just to confirm there is only one cable connected to each of the sockets MCB's. Having said that I think it's unlikely that you could have mistakenly seen one cable when there was 2.

I have a multimeter but I’ve never used it. I can use a voltage checker.

That’s correct. There was only one cable connected to every MCB. I’ll photograph if necessary.

Could be a lollipop circuit

Then opening the cover of the fuseboard will be much easier.

There is a high chance that you've got mistaken.

If it isn't a ring then its a pretty straight forward job for an electrician to change the 32A mcb to a 20A one, along with rectifying the fault you've got.

Or finding the end of the current radial and connecting it back with the MCB.

A friend I know had a similar problem to yours but unluckily he had a very old fuseboard and he couldn't find any replacement MCB's so he had to add a fused spur, limiting the sockets for the lounge to 13A.

It could also be a lollypop circuit which is not very common.

I’ve pulled my kitchen out and intend to bring everything up to date before I reinstall

So that’s a radial converted to ring further down the line?

 

[sparkwright]

Wylex make 25amp breakers - could be your best bet.

Crap plastering, btw.

A good opportunity.

A lollipop circuit is defined as a radial serving a ring. I dislike them.

If the the two 2.5mm2 cables in parallel are not loading any appliances on route then it could be considered a radial.

Yes. If it is a lollipop arrangement, the cable at the CU would need to be 4mm2 or bigger, which would be standed.

To clear all of this fuss, just send a picture of the cable leaving the MCBs associated with the sockets.

In your picture, the fact that there are rubber grommets installed at the entry of the back boxes, I highly doubt the electrician installed a radial supplied by 2.5mm on a 32A mcb.

Since when has fitting grommets meant that everything else is ok?

I reckon whoever installed a radial supplied from a 2.5mm cable won't bother adding rubber grommets.

If you're doing one major job wrong, why fuss over things less important, less prone to causing damage compared to something else?

Imagining it from a cowboy perspective.
