Gas safety certificate ran out in April, water damage to walls/laminate floors caused by various leaks last winter has still not been repaired, together with the carpet that was ripped up when they repaired it.
Back story is that we have been placed in 'temporary' accomodation by the council since our house was repossessed last April. It was a bloody nightmare to sort out and I was 6 months (unplanned) pregnant at the time (with 3 other DCs) as DH was made redundant and I could not find another job after I was made redundant in 2009.
Anyway as the council have no temporary properties of their own to accommodate families, we were given a property managed by a private agency but the tenancy was drawn up by the council (we pay the agency rent not the council). The rent is market rent (LHA maximum of £900 per month) as they expect most families to be claiming full housing benefit I presume. We don't as DH found another job almost as soon as we moved in! We had no choice in the property and we know it would not be worth that amount on the open market.
Now when we moved in, we were told that there was no door fitted between the kitchen and through lounge to aid in ventilation with the gas boiler. I was a bit 
about this until British Gas came to install a new meter and immediately stopped the gas as they said there was a leak so we had to move out leaving all our furniture there. We later found out the owners of the property and the agency were aware of this that was why there was no door 
. The upside was that a new boiler had to be fitted. The owners had to pay for this and insisted on using their own 'engineers' aka cowboys (relatives) rather than the agency people, who trashed the house by cutting copper piping (all new pipes) INSIDE rather than outside (while we had moved out) so it took me weeks to get rid of all the bloody red dust. They left the boiler and all the pipes (loads of them) exposed with no attempt to clean up. We asked for the gas safety certificate after it had been done and after chasing the agency for a month finally got one. Since then we have all manner of problems - boiler not working, leaks throughout the house, when one cracked pipe is fixed, another bursts somewhere else etc. We have had mould throughout the winter because it was taking the owner weeks to get someone in (same cowboys) to repair them whilst we had a new baby. The owners will not allow the agency to do the repairs as they want to do it on the cheap with people they know. The owners are not listed on our contract at all and the agency is listed as our 'landlord' not them. The owners have also been abusive to us including telling my DH that he should not be complaining as the 'council are paying the rent' not us [angry, angry, angry]. Of course DH put him right on that.
Last month the agency arranged for a new gas certificate to be done. The owners wanted to do it themselves and sent the same 'cowboys' to do the job. I asked for their 'Gas Care' cerfication badges and they said they were not certificated but their boss was (he was not with them) so I told them very nicely to get lost as I understand it is illegal for non certified engineers to do this work and I want to make sure it is properly checked. Then complained to the agency who said they would sort it. A month later we have heard nothing. I am thinking that the owner's know that the 'cowboys' they got to do the job are not certificated and that the boiler may not pass and that is why it has still not been done.
AIBU to refuse to pay any more rent until all this work is done. I have also complained to the council about this and they have done nada!
