why fecked? if they just need to work where the tank etc is, no?

Nope rip all the floors or ceilings out it’s plumbed / piped wrong to the rads

Looking at the plans the radiators boiler and tank etc are all in the correct place, if the house builder builds several of the same type (model) of house (which they have) then surely it's a mistake where everything joins together in the cupboard upstairs.

The boiler is in the utility room Baxi heat assure, directly above it on the first floor is the tank cupboard containing a therma evocycl cylinder plus a small red tank and a small white tank, all the pipes running to the radiators must be in the same place, no?
 
Nope as the zone pipe work is in / under the floor so all the houses are the same / have your problem

For example

See that radiator pipe work is separate to each zone so if there’s a rad on the wrong zone / mismatched all the pipework would need altering under the floor
 
Ceiling will likely have to come down
 
What ever needs doing then its the developers responsibility they should instruct their heating contractors to correct the mistake ? , They are often slow to react to the problems be persistent but polite you have done well to diagnose the issue , are the manifolds visible or accessable? can you see the motorised valves with possibly a silver box on top ? a few pictures may help if the contractor has access to the manifolds? it could be quite simple to swap 4 pipes over once identified, or it may mean removing a floor covering and taking up a section of floor for access, worst case it's a section of ceiling may need to be removed.
