Is this normal for a boiler?! Photo attached

[LemonsIrdl]

The pipes under our boiler have gone dark blue… and bits dropping off under the boiler.

had two engineers come out and nobody can explain it?! Is it dangerous?

If the fully qualified heating engineers can’t tell you what it is and if it’s safe, I’m not sure a bunch of MNers can offer you much reassurance tbh.

Try putting this in the property section and ask for piglet Johns help? Think you need to notify mn and ask them to move it.

very intrigued to know!

Thanks!
