We have been without our gas boiler for approx 18 months, meaning we've had no heat source or hot water. we verbally contacted our landlord but he insisted we paid to get it fixed, then he would give us the money back (we have no written contract).

After much research i now discover it is his obligation to fix. The issue is, we are now moving out. However we are bitterly fed up with him

Although we can not prove we contacted him to make aware of the situation. if he had maintained his legal obligation of doing gas checks annualy (which we can prove he didn't) this would have been picked up then and resolved.

Does this help us in our case, of trying to make a claim against him, specifically against not fixing the boiler?

Any help, advice, feed back would be so genuinly appreciated.
Thanks in advacne :-I'm not
