Boiler leak

Hello

I have a small leak in this plastic part on my potterton combi boiler. 

Any idea what this is for and where it's coming from? It's not losing pressure so I'm assuming it's something to do with the condense pipe

Looks like a "Promax condensate trap"

It may be loose or the o ring seal may be perished or the leak is from elsewhere on the body or pipes attached to it {that may need a plumber, perhaps need a Gas Safe one, to access and fix?}

Google the part name and your boiler model number to be sure.  You'll likely find the installer manual online with parts diagrams etc.,.

Condensate fluid is mildly acidic so be careful to catch it in a suitable container and wear gloves / wash hands.

Contacted my usual guy who does my boiler service . Decided to book a service but they can't do for 3 weeks. Will this be ok until then ? I've got a sizable container under it 

What does this part do?

Yeah it'll be fine. Condensing boilers recover heat from the combustion fumes and it results in a liquid - condensate - to get rid of. Because its a mild acid even the flue has to drip back into the boiler - thus the condensate trap and waste pipe - the one that sometimes freezes up in winter. It'll be fine to wait for a service.
