I've owned my 3 bed Victorian house for 7 years. There was a little bit of damp in the downstairs bay window but nothing serious.
I moved for work at end of August this year and rented it out. Within a few weeks the tenants (3 adults & dog) started complaining of damp and mould. When I went to inspect the house was very cold.
They said they are worried about high heating bills. I do understand this but have told them they really need to turn the heating up.
The boiler is in full working order as are the extractor fans in the kitchen and bathroom.
I installed new double glazed windows throughout when I bought the house. It also has a damp course installed.
Now they are complaining that there is black mould and that one of the tenants' asthma is getting worse.
What can I do to get them to turn the heating up?
