If you are on means tested Social Care keep a copy of all of your expenses and receipts for conversions equipment and care costs.
This year a cap on personal costs of £72,000 should have come into place. The government has put that off for four years, but it is backdatable and you can set all expenditure against the cap if you need to then.
This means that if/when the legislation (which has passed through Parliament but it awaits a start date) is activated the total you should ever have spent is £72,000. At that point the Social Services pick up the full amount.
If you are not eligible for Social Care because of savings and investments keep them too. When the law comes in you too can claim Social Services care and enjoy the same cap.
I am so wonderfully optimistic!
