So after having no real problems with my flat for over a year, a few days ago my landlord phones to say he’ll be in India until the end of the month. The following day I wake up and there’s no hot water. This is completely unreasonably unlucky and I wish to protest.

Update: should I be concerned if two plumbers arrive, umm and err for an hour, and then leave saying they need to contact a “technical expert”?

Further update: all fixed now!
