Job description

I have a leak under my kitchen/bathroom that is getting progressively worse. My guess is that it is a central heating pipe that goes into a heated towel rail. There is damp damage behind the bathroom wall in the kitchen, under the wooden 'floating' floor. Sadly, my guess is also that the pipes are in concrete (as they are in the bathroom). Please see pics. I would like a quote to find and fix the pipe. I will make good.
