One of my clients dealt with in a very sneaky way. He had his boiler engineer rig the boiler to keep the heat on to heat the walls and structure when the tenant was one who turned it off to "save money", including having the lounge rad on and turning over every other rad. Tampered TRV's solved that too, and was a lot cheaper than arguing over condensation problems and the damage it was doing.

Based on the information posted, I offer my thoughts.Any action you then take is your liability. While commending individual effort, there is no substitute for a thorough review of documents and facts by paid for professional advisers.
