My parents have asked me to look into Equity Release for them and after a quick Google and not really liking what I found I thought here may be a good place to ask

My dad is 76 & my mum is 70, my dad is retired and my mum still works 15 hours a week although she is now struggling to keep this up, they have a house currently worth around £750k with an £80k interest only mortgage on it, they obviously don't feel that their pensions are enough to support them if my mum stops working and would also like to do some work in their home to make it more suitable for them as they get older.
So is equity release ever a good idea?
Thanks in advance.
