I've bleeded some of the radaitors in my house and there no more water coming out of the pressure relief pipe, however the pressure on my gauge is still between 2.5-3.0bars, any ideas why?
Could be a blockage in cappillary tube to gauge. Easiest way to find out is to open up bleed valve on top floor radiator and depressure system completely, ie when water stops coming out at pressure and just weeps from bleed valve. Then check gauge is reading zero. If you find pressure doesn't drop make sure filling loop is shut

The pressure release valve lets go at 3 bar.....if you want to reduce the boiler pressure, continue bleeding water from the radiators. It will take a while but its the most fool proof way!
