thanks all...so something like this should do the job?

Is there really any material difference (given that the OP presumably only needs SP contacts)?Probably, although items like these would be a more likely choice ....
Best be careful when you walk in a shopping centre, supermarket or petrol station too. Be steady when you sit in the doctors surgery, go for a swim, or press the button on a pelican crossing.Thanks ban-all-sheds. I was advised by my local sparks that having different phases in one room, where potentially someone could connect two phases via their own bodies was not allowed (or at the very least inadvisable) - and I have to say, seems sensible. But he is the expert (or not, as the case may be). The warning labels simply point out that there are two different phases used, with potential high voltages between them...but again, as advised.
The problem I am having is finding a relay with 240v input to energise the relay, and 240v outputs for switching the other phase - all I can find (because I don't know where to look!) is low voltage switched relays that use either DC or low voltage AC to energise the relay. As you say, provided I have isolation between contacts and coil, I should be fine...are there any building regs issues in such an approach?
Thanks
the boiler service engineer uses the utility room sockets for his testing tools...which would then be on a different phase!
By the sounds of it it has not been.I have a house which has the strangest electrics ever - converted from 3 phase.
I have a house which has the strangest electrics ever - converted from 3 phase. Originally, it used a three phase board, but lighting circuit, power circuits etc were random - and highly dangerous, because I could have sockets on one phase and lights on another in the same room.
I had a sparky do his best to sort it out - we now have one phase for downstairs, and one for upstairs, with the third not being used - and lots of warning labels. However, I have one issue which I cannot sort out.
Thanks all for responses, although sarcasm not entirely helpful...I took guidance, whether it was out of date or not! Plan is to move the boiler onto the same phase as the remainder of the heating system, which has the added benefit of it being supported by the battery back up in the event of power failure - the inverter can provide sufficient output. Thanks again.
