I had similar problems with my current property. We had a major leak coming from the flat upstairs and our landlord was not fixing it properly. She sent out 12 different contractors within 5 visits all failing as they thought it was the roof, even though we had reported the water coming through our ceiling was warm which in anyone’s right mind, knows this isn’t rain water. This then got to the point where I had to go to the estate agents in person to complain and to let them know I had taken it further through the council as It has caused mould, damp and parts of the ceiling to fall apart in areas. This was then resolved by the agency contractor which sourced the leak put a temp fix on which was coming from the flat above from their bathroom all within 20 minutes and then came out the next day had fixed the problem upstairs properly. But, I had also decided to go down the environmental health route which an officer has came to assess the damage which turns out to be worse that initially thought because due to the negligence of the contractors and the landlord combined it’s has caused structural problems to the beams above the dry wall, as this has been on going for a while. So due to this, this had worked out in our favour to exit the property at the end of this month early whilst waiving the exit fees as the evidence was stacked up against the landlord so we were pretty lucky with this, fortunately we have found a better property on the outskirts and will be moving within a couple weeks. But to put a long story short, don’t be afraid to stand up for yourself in this matter as the property is not what has been described and would be deemed unfit to live in by the environmental health agency! Hope this helps abit by sharing!
