It's your baby now I'm afraid. But DON'T PANIC!
I was in the same position, but needed all new central heating system too!! Because I'm on low wage, I was entitled to the government grant from WarmFront. They put in a whole new system and I didn;t pay a penny. It's the government's way of protecting the vulnerbale. If you are claiming any sort of benefit, or get child tax credit (like I do) then you could be entitled to some help. I asked at my benefits office, but 'google' "Warmfront", and it gives advice and a phone number to call to see if you are eliglible.
You will have to wait though. I know what you're going, I moved in October but had to wait till February to get any form of heating in my house. My kids and I lived through the coldest winter in years with just two oil filled radiators in the whole house. I wish you luck
