So currently you have hardly any disposable income, but in a couple of months, when the first loan is paid off, it will increase by £300 pm, which will feel massively easier and then again, in 8 months, ie later this year, another loan is paid off, so another big jump in your disposable income/amount available to pay off debt, save and live a little, although more money should be directed towards getting out of debt and building some savings.
There is light at the end of the tunnel and in your case, I don't think it's necessary to sell up to pay your debts off, rather sit tight and concentrate on reducing costs especially interest rates on the credit card debt.
Throw as much as you can at the credit cards and make sure you're always on an interest free deal and if one gets near the end, while you still have a balance, apply for another one, or see what offers are available on any unused cards you have.
As far as future 'emergencies' go, as long as you get all your credit cards onto 0% deals, you could start to build up some savings to be used for genuine emergencies like car or boiler repairs etc.
I know you say you have done things like cancel sky, but there's often more savings to be made, so the Moneysavingexpert money make over gives a systematic list of things to look at.

On the other hand, you are using so much petrol that suggests that you live too far from your work so is there any way to change this? Move closer to work, work from home some days, get a job closer to home?
Your DHs car sounds like it is expensive to run in terms of tax, insurance and possibly fuel. Could he change it to a smaller, cheaper car? Some older cars have low insurance groups and £0-30 per year tax, plus lower fuel costs than a BMW saloon.
Is there any way you could reduce your oil costs? The price fluctuates seasonally I believe and sometimes communities run 'oil clubs' where they use group buying power to get the best price by going to the available suppliers and saying 'if we all buy our oil from you and take delivery on the same day what is your best price' and play them off against each other.
