Scratches head, hmmmmthanks for clarifing that and your honesty.
i am taking no more part in this topic.
no need to scratch, your BG pal took out a working BBU (its age,performance etc etc is of no importance at the minute)
and fitted it, in your property 36 hours ago
has he notified his work to GSR ?, if not he may as well have worked for Primark or WH Smiths, its as big a cowboy job that i have heard of for a couple of years.
