Job was done well. System flushed out and property left very clean and tidy afterwards. Very professional job.
The reason I'm giving 3 out of 5 though is that on the day, Reuben identified that a radiator valve couldn't be replaced as he didn't have the right size, so would need to come back.
However, he hasn't done that and won't reply to my calls or messages.
So, I still have 1 radiator not working and now need to pay someone else to resolve.
