A good colleague (Barney), recently moved flat and into one of his friend's properties. At the time they also worked together full time but the landlord has since changed job. They're both musicians and gig together now and then. Barney has an 8 month old baby and wife and the new flat seemed a good move from an old draughty victorian terrace.
It seemed like a good idea at the time as they got along really well. What could go wrong?
Well, the heating started to play up and they asked for it to be looked at. Two months later they still have no heating and when an engineer did come round to check the boiler he couldn't find the fault and as he was taking his time to try and find it the landlords wife asked him to leave as it was costing too much!
Barney is a big softie and doesn't want any aggro but he's also taking cold commando showers in the morning and his baby can't sleep as its so cold at night.
What action (legal, I've suggested a set of bombers already!) can he take against the landlords to force them to fix this immediately as we're forecast a cold spell next week and it can't be fun for him and his family.
