On the initial inspection I was told that the radiators would be removed and flushed and values changed. However this didn't happen the guys that came re-plumbed some pipework to 2 radiators this work was completely unnecessary and completely unrelated to the fault in the system, I was charged nearly £350 for this work. I have since had another heating company fix the problem and in doing so removed the completely unnecessary change in plumbing.
I really can't recommend this company as they didn't do the work they initially quoted for and really I have wasted £350 on pipework that was ripped out several months later
