My landlord has left me without hot water for over a year... Can I claim compensation?

I have had no hot water throughout the house, as the boiler is broke. I can just about manage to get heating out of it but NO hot water. I have to run the electric shower for a bath as it's not strong enough to have a shower with, but takes up to an hour to run a bath which is NEVER more than lukewarm. I have told him on many occasions and he has ignored me or poo pooed it. On the first night I moved in, there was a flood due to the blocked drains that flooded into the house ruining all my unpacked boxes. I've taken it to the Solicitors but suddenly he want's to fix everything overnight. I have been advised not to let him fix the repairs until the survayor comes out and gets evidence. The landlord is getting snotty with me in texts and its stressing me out as im pregnant and I just want to get out of this house now, which the solicitors is helping me to do. I just don't know if its worth all the stress? It's not just the water.... I have no cooker connected, I have one but in the 6ft x 6ft kitchen there is no connection for a leci or gas oven. Also the house is SO cold and my fire was condemned in Early January of this year. The gas inspector said I'm lucky to have woken up at all. My landlord is an utter waste of space and I hope they get all they deserve when this case get's seen to... I hope...? I just need some reurance ( I can't spell lol) thanks in advance
