Here is the state of my boiler. It's in a flat that was rented out and this
is the first chance I've had to look around.

What's causing the leak? I thought it was condensation at first, but
obviously not!

There's a wet patch on the wooden platform which the tank is sitting on.
But I guess you knew that.

Not entirely sure how you expect anybody to give you any further
information eg detect where the water is coming from, based on that picture?
