My hot tub lights were flashing telling me there was a fault. I chose Hot Tub Barn after looking at their website and being impressed by all the DIY solutions they offered complete with video. I described the fault, they suggested a solution and sent me the parts in the post. No guarantee of course that it would work as they were not coming out to test all the electrics, but I fitted the new thermostatic controls in the heater and hey presto, fault cured. No call out fee, just the cost of the parts (and a wet arm, which I was warned about when discussing the issue with Trevor on the phone). A good bunch of people.
