Power Flush

Hi

Once again looking for feedback from any residents that have had problems with there central heating radiators. Because I have just had british gas out to fix some leaking radiators on my homecare agreement. And once again they have tried the big sell on the powerflush product they keep on saying that they have never seen systems as bad as this estate. But at just under £600 not sure what to do, has anyone had this done by british gas or used another company that is cheaper.

And once it was done did your system work better.
