Hey all, Looks like we need to get our system flushed as we have a couple cold spots and areas on our radiators. I'm getting quoted 450 for 6 Radiators - 2 bed Flat. That's including VAT. Now this company does come highly recommended, has been around for quite a bit and guarantees that the system will be clear for 5 years. From plumbers and others who know about these things, does this sound good to you? From doing research online it seems perhaps slightly on the high side (50-100 more than some would expect). BUT - A big concern of mine is that this isn't just a company that half arses this, I want something that will last. Reason for that is that the last time this system was flushed was 2010 and it's already showing these signs. (previous owner).
