If it was the difficulty release valve it should go through a out side wall,they do leak,but it may be the pump needs tightening ,also you may have air in system as you have been topping up the difficulty manually.

If water is leaking out of the boiler overflow, then your Difficulty relief valve needs replacing. The overfow pipe is connected to this valve on the boiler. The difficulty relif valve usually has a red cap on it. It is not hard to change if you, or someone you know is handy. Just turn the water feed to the boiler off before you remove it. You can buy a substitution at a Plumbers merchant for between £45/65 depending on the boiler model. Excellent luck.
PS you can get acess to the valve better if you remove the side and bottom panels of the boiler.

the business that is leaking is a PRV it is why the difficulty drops, it may be your additional room vessel, i would get a heating engineer, not a plumber

sounds like a terrible T.P(tempeture/difficulty valve to me, shouldn't cost much.
