I rent privately. A few days ago I reported a leak in the kitchen which means I can't use it right now (having to use washbasin). They have been ignoring me.
In theory I have various avenues open to me as I understand it but in practice if I annoy the landlord too much he can either put up the rent (it has gone up by over 10% this year) or give notice.
If it helps I have kids who stay with me some of the time and the landlord knows this too.
