Hi guys I recently had a 2 leaks under my concrete floor which I fixed but I'm still loosing pressure. I've bleed all the radiators and close all the pipes off on the boiler and and tested it and it's fine. Any ideas?

What system have you got? Is it old or new?
If there's an expansion vessel that's where'd I'd check first and check the pressure,
I would then check pipework around boiler filters, controls
I would then inspect every rad valve and air pins with a bit of blue roll removing caps trvs ect...
I would then turn off the boiler wait 10 minutes and check the condense, the white pipe there should be no water running here, if there is you need to phone a gas engineer and prepare for bad news
If all above is okay, hire out a thermal imaging camera, run the heating on max and check all Pipework in wall and floors, leaks tend to show up like filling a basing slowly, don't dig up loads of holes until you've inspected the whole house, if you're problem persists then your really unlucky lol
