Many thanks, Guys & Gals. Had quite a good day so far, the central heating timer has broken so I have spent the past two hours fitting a new one. A bit of a pain as the original type is no longer available and all the connections have changed, sorted now though.

My daughter took me out last night as a treat, went to the Gaucho Grill in Manchester. An Argentinian steak bar. If you are into beef I can thoroughly recommend it, fantastic fillet. Just of for a birthday game of squash now.
Thanks again.
Jim.
