Okay, understood. Thanks for the link. It might be the metal light switches that cause the issue with the lighting ring. I suppose if I replace the metal switches with PVC switches, it can be moved over.

I thought these get terminated on the neutral bus? e.g. Ring leaves the breaker to the house with + on breaker and - on neutral bus, ring returns from house with + on second breaker and - on same neutral bus? I thought the point of a ring was to allow the current to be drawn from both ends of...

Don't know why, but MK and Wylex seem to abbreviate their [C]onsumer [U]nits to CSU in the product description on various sites. Have no idea what the S might be, but just wanted to be anal about the description.

Don't know boiler make and model, will have to check at home, it's fairly new. The control is a Hortsmann Channel Plus Excel. In the garage behind the control is a Honeywell junction box where the cables from the tank thermostat, boiler water/heating and power are wired, presumably before...

I have unfortunately broken the plastic part of the valve off whilst trying to undo the valve to radiator connecting nut. It seems that the plastic has become brittle over time and has discoloured somewhat. There are some plastic clips left in the metal part of the valve with the pin. In...
