Hi Puddy.
I have something called Income Protection insurance. There are various factors on how they work your quote but mine covers me after the first two weeks of not being able to work and would pay out enough to cover all my bills per week. It covers temporary disablement (e.g., broken finger) and also total disablement - something that would stop you being able to do your job for good. It's quite expensive for me but the quote would differ depending on how much you would need it to cover if you couldn't work and also how many weeks you could spare off work before the insurance kicks in.
I live in jersey so my insurance is with a local provider but if you google income protection insurance, it may give you some more info.
I hope that helps.
