I am not a heating engineer. Have you looked outside? if your boiler has a pressure relief valve it may be "letting by"
(A prv has a pipe from inside to outside, and outside it will run to a drain / gutter. The idea being if the pressure gets too high the prv opens and "dumps" all the water to reduce pressure. If it has operated it may not have sealed properly)

Pressurise boiler to 2bar, shut isolating valves to flow and return under the boiler, leave boiler unused for as long as possible.

If pressure drops then leak is somewhere on the boiler itself, if pressure drops when you open the valves, then leak is somewhere on the pipe work/rads etc.

Thanks for your reply ,I can't see any shut off valves coming out of the boiler so I m wondering if they are integral or part of the boiler itself,instead of being on the pipe work.The boiler is Glowworm Energy.
