pressure seems slightly higher than normal but wont turn down water leaking from copper outlet pipe outside, heating working normal water working what could be wrong

possibly your expansion vessel. does it rise to 3 bar on central heating mode? if the boiler shows 1 bar and heating isn't on and then rises to 3 bar on its own then your filling loop is open or if not that there is a cross leaking situation within the boiler.
worcester charge £210 for a visit and fix whatever the prob.
