I’m not sure it works like that. If you reach an age and deteriorate in terms of physical health the Social Services will do a financial assessment for your care needs:
In England, social services will typically conduct a financial assessment to determine your eligibility for help with care costs if your savings and investments (capital) are below £23,250.
Here's a more detailed explanation:
Capital Limit:
The government sets a capital limit of £23,250, which includes money in bank accounts, investments, and the value of assets like a former home or second property.
Financial Assessment:
If your capital is below £23,250, a financial assessment (or means test) will determine how much you may need to contribute towards the cost of your care.
Self-Funder:
If your capital is above £23,250, you will be considered a self-funder and will need to pay the full cost of your care until your capital falls below the limit.
Financial Assessment Process:
The financial assessment is free and happens after a needs assessment or carer's assessment.
Council Contribution:
The council may contribute to the cost of your care depending on your needs and how much you can afford to pay.
Example
If you have £17,250 in savings the council will calculate your tariff income by subtracting the lower capital limit of £14,250 (£17,250 - £14,250 = £3,000) and then dividing by £250 (£3,000 / £250 = £12)
