Today, nine days after it was installed, my shiny new oven is working.  The fitters connected it all up, went to demonstrate it to me - and nothing happened.  They checked there was power reaching it - there was - shrugged their shoulders and left.

Today, the first available slot arose for a repair man to come out... in under ten minutes he had identified and rectified the problem - a loose wire that he says was visibly not connected...

So now I have a fully functional kitchen once more, with just some tidying and cosmetic work still to be done.

And a reminder that details matter, and small things make a big difference - which is pretty much what Operation Agri want me to say on Sunday!
