That looks very much like an old spring tensioned safety valve.

These often drip when very old. These are still available and usually
a fairly quick and easy job for a plumber to replace.

It is unlikely to burst and flood the place and would probably
weep for a long time without being too much of a problem.

Its a old style saftey valve employ a GSRI to replace it and service and test the back boiler and fire front , the regulations have been contravened if you have removed the fire front and are not GAS SAFE REGISTERD . KOP

Thank you I'm not touching anything as I know nothing, the engineer was in there December last year today I noticed salting outside the small cupboard and signs of long term dripping it's dripping probably ever 10 minutes but has obviously damaged some brickwork, thanks your advice helped
