I had to have mine done (15 rads), phoned around got prices from £850-£350. Prices depend on where in the country you are and who you get to do the work. I had it done for £510 from a London company - which seemed fair as they gave a guarantee with it. The £350 was a bit too cheap and NO guarantee on their work. Try using a member of the powerflush association, otherwise you don't know who you are getting AND if they really know what they are doing. Also make sure they add inhibitor in the system when they are done, or you will have the problem again.

£340 power flush, including a boiler service, from a local tradesman (SE England). System running a quieter. Never had it done before, in fact not heard of the process until I described the knocking sounds to a number of HE/plumbers. Not sure the process is necessary every five years but worth bearing in mind if other processes do not work.
