the utility room toilet which was leaking does not have a lot of water
in, could this be the cause of the odour?

If you've got any little used toilet or basin etc, the water in the trap
can evaporate and let smells up from the drains. A badly made stack can
sometimes pull the water out of traps without you knowing.

You can, of course, see if this has happened in a toilet, but not other
traps.

If you have a suspect basin etc, try taping up the overflow with gaffer
tape and leaving the plug in.
