There are 11 services to connect to a combi boiler (9 to a conventional

It is almost never the case that all 11 are just exactly as they need
to be. You have to choose a location that (other things being equal)
minimizes the total cost of installation.

Approx order decreasing awkwardness.

Air intake. Flue.
Flow & Return.
Fuel
Cold In & DHW Out.
Condensate waste
Safety Discharge Pipe.
Electric supply
Heating control signal.

I would have thought the discharge pipe brought down to ground level
outside would have met the rules. A condensate pump ( sub £100) can be
used to solve condensate problems.

Thanks for that. A discharge pipe near ground level could be an
option.
