The 3 you called won't be interested because there's not much money in it.
I'll ask a friend at work if he's interested.
I'd do it myself but I go I'm off on Holiday for a week
TBH, it's a fairly easy job to do.
You'd probably be able to do it yourself, using compression fittings and a bit of advice.
Thanks for the advice. I assume it's something that a plumber rather than a boiler engineer would be happy to do?
