Has it been completed eg commissioned then ?

It's building regs so doubt it was signed off

You need to be gas safe to wire in that thermostat so best get him back or another one in

Providing you don't break a combustion chamber seal you can remove the cover of a boiler, and from what I understand there aren't many boilers in the UK where you would need to break a combustion chamber seal for wiring purposes.

You unit is going to need a power supply (line, neutral and earth). Regarding the link in the boiler (that you've shown in another picture) connect 3 and 4 on the new device to the terminal block with the link in it (removing the link as you go) and you should be good to go.

I might be inclined to use some 5 core cable (custom made you might say for this as you can use brown, blue and yellow/green for the L, N and earth). You should sleeve the conductors you use to connect the link terminals with brown tape.

Thank you I appreciate that
 
Bottom right of page 14 in that file you linked above... Conditions for 230v controllers. Sleeve cores with brown tape (at both ends) and connect as shown in that diagram to terminals 3 and 4 of the thermostat receiver and you should be good to go.

please read it again carefully as the seal is the cover,

only time you or the customer can remove the cover is when it a Decorative casing: These cases can usually be removed by the consumer e.g. can be lifted off or are
hinged panels and do not need to be unscrewed.
