If you have more than the agreed amount of savings, which I believe is £23K+ and find a suitable care home, what happens when you run out of money? Would the local authority move you to a cheaper, maybe less suitable home? This is assuming a spouse is living in the family home.
The first thing to do is to contact your local authority to ask them to reassess your needs (if you haven't been assessed already, everyone is entitled to have one, regardless of how your fees are being paid) and also do a financial assessment. If the local authority then has to step in to pay your fees, you might have to move to a cheaper care home where the local authority is paying for rooms.
However, as well as showing that the new care home will meet your assessed eligible needs, the council also needs to carry out a risk assessment. The purpose of this is to check that such a move won’t affect your wellbeing, whether this is physical, social or mental.
After all these assessments, it might be the case that the local authority determines you should stay in your current care home. They should then increase their payment rate to cover the higher fees.
