Once I buy an annuity will I ever have to pay any more premium?
Once you buy an annuity you will never be asked by the Insurer to pay any more premium, they are guaranteed.
The only time you may need to find any more money is if care needs increase and /or care costs increase by more than you expected and allowed for. Then if you wish, you can buy a further “top up annuity” but this will be your choice, the insurer can’t increase the premium on the original policy, no matter how long care is required for. This is one of the advantages of an annuity – it caps the cost of care and continues indefinitely.
