Can someone please tell me:

1) likely cost of fixing this?
2) does entire boiler has to be removed to fix the problem?
3) do i need to very urgently fix this or is it ok while plumber gets around to coming in couple of days?

Hard to tell from so close in but looks like a flow or return pipe leak. It'll wait, easily fixed in 30 minutes but you'll probably be charged for an hour to cover the callout

thanks. i can see some "green" stuff gathering around the pipe connection where the leak appears to be. is this anti freeze? if so, it is relatively easy to replace or am i looking at an expensive repair.

the boiler is a conventional boiler from bosch and is about 3 years old.
