Hi Al long time no see as they say, what ever the cost will be its got to be far cheaper than the repairs your likely to have shell out for with the cold winters you get down in Swindon. I remember fitting your machine and it was not quite winter and there was Marks up the road from you I fitted in Feb and that was bluming cold. Swindon is not the warmest places on the planet from memory.
You know how the saying goes "Pay cheap buy twice."
