Speaking as a hospital chaplain (that's with an 'a' - Chaplin was a Charlie) I see nothing at all unusual in this. In my own hospital, the nurses and cleaners will often report things to me and ask me to 'clean up'. The patients less so - if they claim to see anything they get medicated. It's quite funny hearing people who believe in very little trying to explain and admit to having seen or felt something 'creepy' they can't fit into their scientific models.
Hospital chaplains in the UK are employed, either full or part time, or on a retainer. So if the chaplain deals with this, it's just part of their job, and they don't cost anything extra. Well, maybe a cup of tea afterwards if it's a particularly unpleasant job. It's just part of the spiritual and pastoral care of a healthcare institution. I'd expect there to be issues in a new build - I really don't see why this made the news!
