baxi boiler keeps loosing pressure - no leak?

Sorry, can't help, I have the same problem! In my case there does seem to be a discharge of water through what appears to be an overflow pipe - the pipe on the right hand side of those connected to my boiler - but I've no idea why it should do that, especially as the pressure doesn't get too high.

Only leaks indeed, Steve, unless the boiler is discharging water to the outside. If there are absolutely no visible leaks (under the floor etc) then the leak may be in the heat exchanger where the water escapes as steam with the flue gases. If its a new one, time to call the installer! Good luck with it.
