Live-in care is expensive, but there are sources of money for care you can claim to help you pay for the live-in care you need.
Attendance Allowance can be claimed for care at home. This is not means tested so you are able to claim the allowance regardless of how much money you have. The weekly allowance ranges from the lower rate of £47.10 per week to the higher rate of £70.35 per week.
Other sources of funding may be obtained from the NHS, you local authority, the Independent Living Fund or from various other funding methods such as eg. buying payment plans to cover care costs.
However it does depend on why you need care, the funding available in your area, and your financial means.
