"Measure three times, cut once" is a maxim I have lived by and sadly, it seems to me that you have looked at the problem in a superficial manner and acted in haste.
I am sorry if this seems negative and I found hope that you gave not caused damage to other components.

Have you tried Ray's suggestion of contacting Sargent for a wiring diagram.?

Thanks for all your help so far everyone. I do understand vehicle electrics, struggle a little with wiring diagrams though. I did try and look on that link for mine but the diagram style was completely different for my 2007 Bessacarr E560. I have however found a blue/white wire that became live when the engine started entering the combined fusebox/relay housing so I snipped it and sure enough the lights now stay on with the engine running. Only problem is the leisure battery no longer charges and the fridge no longer works on 12v so more digging is required!
The lack of battery charging is not such a big issue as I will be fitting a DC-DC charger very soon.
Attached is a typical Sargent system. To keep habitation electrics On the EMC relay needs to be modified by removing the red/yellow wire. The step retract and fridge 12v will still work correctly. On later models the relay may be incorporated into the Sargent electrical panel.
The OP needs to find the Sargent schematic diagram for his model, possibly from here https://sargentltd.co.uk/tech-suppor...-Schematics/25
Carry out some investigation in the van to find the relay in question.
Search the internet to find how a relay works and then identify the connection that energises it when engine starts, disconnect that connection and your power should remain on whether the engine is running or not.
Alternatively find an auto electrician and explain what you want done.
Obviously, as Dave has said above not really something you should do to a UK van.
On second thoughts that may not be such a good idea as without knowing the way the vehicle is wired there is a possibility that your fridge will not run on 12 volt and if you have a self retracting step that also may be affected.
So you will need to do some more in depth research before finalising any quick modifications.
It can be done but the registration for a British MH denies that chance........
Buy German and that problem does not exist. Sorry, not what you wanted to hear....
As you are not a FULL member I cannot communicate via Private Message and there is no way that I would display such information as it could be used by someone unsafe to do so and then there could be a negative outcome involving legal proceedings...... Not good.
I want my habitation lights to stay on when the engine starts!!!
Okay so I know the manufacturer did this to meet a UK legislation bla bla bla. But I would very much like to have my habitation lights and water pump etc to stay on when the engine is running. Please don't lecture me on reasons why not to, its my van and im entitled to modify it how I please.
So, does anyone know how to achieve this? Its a Bessacarr E560. When the engine starts you can hear a click of a relay behind the drivers seat in combined fuse panel. Im assuming this relay gets a 12v live ignition feed when the engine starts, so is it possible to snip this wire or put it on a switch so the habitation panel is fooled into thinking the engine is not running? Has anyone else tackled this issue before?
