Has it got a built in RF receiver for the thermostat on the front panel?
Can you post a pic?
The manual seems to suggest it is relatively easy to get to the wiring behind the panel, so it may be possible to bypass the receiver.

as @RandomGrinch says, post a pic of the control panel of the boiler so we can see what your set up is

Here we go, thanks so much!

Oh dear, a Salus receiver. I'm afraid that explains a lot!
For a first attempt, try sliding the switch on the front of the receiver towards the dark circle.
If that doesn't achieve anything, next try connecting together the wires in terminals 3 and 4 of the receiver...

Isolate the power first (these wires are carrying mains voltages) and connect them together safely in a separate terminal block.
If that works, you can then use the controls on the boiler to look after the C/H until you install a new stat.

A little bit more info... the end goal is to establish that the heating aspect still works which im 99% sure it does and then to replace the receiver and commander unit with something that works! Currently have the horrible Salus RT501RF (TX) and would like to replace with something like a Hive or open to recommendations Thanks

I have tried the switch in both positions but makes no difference and tbh im not sure which position it was always in! Randomly the heating did come on last week and we put it back into summer mode as it was just blasting on but it wont switch back on on command.

'connecting together the wires in terminals 3 and 4 of the receiver.' is this essential to testing the receiver or can we just get rid? The only point is that i want to know that 100% the boiler has no issues - the water heating is totally fine.

This completely bypasses the receiver, without delving onto the boiler PCB to find a connection; these two wires will need connecting anyway, to allow a new stat to be installed.
I would cut off the crimped on connectors, and join the two wires together in a single terminal block (again isolating power safely first!).

Or could i be a total cheapskate and look for a used Salus receiver if this is what has failed?

You could, but I doubt anyone here would recommend that!

All done and heating works fine I guess i can just now remove the live/earth from the Salus BC600RX and leave them? Thanks

It's a Live and Neutral to the Salus
Yes, you could just remove them, they are safe enough to be left there, if the crimp covers are intact.
The Salus could remain in place as a convenient blanking plate.

If you want to connect a new on/off thermostat, the power can come from the L, N & E terminals and the switch wires would connect to terminals 1 & 2 (after removing the link)...

Alpha do have their own controls (Climatic) that link to the bus connector - these allow the boiler to modulate better, and potentially improve the boilers efficiency, but I'm afraid I have no experience of these.
