The Free Money Advice Service has been setup by the government to provide impartial advice on most financial matters but is particularly good on Equity Release.
Equity Release is a minefield but a necessary minefield! Get it right and older people can raise money on their property - potentially allowing them to afford to stay in their homes for the rest of their lives. Get it wrong and they can accumulate an enormous debt and effectively disinherit their children as the finance company claims their home in order to repay the accumulated loan when they die. The link below may help you decide whether this might be a useful route to go down. However just as importantly consider using a financial adviser.
This is a simple AgeUK Equity Release calculator which will help you find out how much an equity release loan would allow you to raise on your house.
