I have personal accident insurance , the company Ime with arnt now taking on new customers it’s called cica , I had an accident 5 years ago that resulted in having a year off work they paid out no problem at all , just had to send the hospitals report of the operation I had and a covering letter from my GP stating how long I was off work and why ,paid the mortgage and main bills , I think you need to be selective what insurance company you use but if you have a mortgage to pay it’s a no brainier but to have it
