my worcseter boiler keeps losing pressure?

Yes it could be the pressure relief valve. try changing that first but it could also be that your expansion tank needs re pressurizing!! i would get someone to re pressurize the tank first up to 3/4 bar then see if prv is still leeking . dont let anyone tell you the tank needs changing ( they prob dont know how to re pressurize )!!

it's not an overflow.
it's a prv discharge pipe. for when to much pressure is in the system.
fit a new prv.

if you can see water dripping for the overflow pipe then it means your overflow valve is leaking remove and fit replacement
