My boiler pressure keeps dropping i top it up to about 1.5 bar and after about a week it has dropped down to 0.5 bar. I have checked all my radiators and there are no leaks and i have checked around the boiler and there are also no leaks. How can I get my boiler pressure to stay and the correct level. It does this all the time regardless if ive had it on or not.
Would second that answer. Not always easy to see if it's leaking from the overflow. My tip is put a bag over the overflow pipe with a rubber band. See if you catch anything. Info for your service engineer if nothing else.

check the pipe from the boiler to external wall has that been dripping ?
maybe a faulty prv, or faulty expansion vessel.
