Combi boiler over flow pipe?

[Sm1990]

I have a end terraced house. Boiler attached to concrete wall on the end of the terrace. There’s a copper pipe curved into the wall with maybe a 1-2cm gap. The water sometimes leaks onto the wall and I’m worried about the damage it might cause. The kitchen drains are on the other side so would need a few pipes to drain into there. Any other solutions?

It’s a safety device and shouldn’t leak unless there’s a problem time to call a gas safe engineer out sorry to say

I realised I'm asking a question about the wrong item! What I meant to ask about was the white plastic pipe which is different to the copper pipe - you can tell I'm a novice to this!

This should lead / connect to your drainage shouldn’t just terminate in thin air or onto a roof
