The Isles of Scilly Council has been given an additional £43,398 for adult social care in the next financial year.
It will also receive £35,765 in 2018/19 and £17,841 in 2019/20, bringing the total to £97,000 over the next three years. This is an increase of 2.79% if current expenditure levels are maintained.
The allocation is the islands' share of the £2 billion given to adult social care in Chancellor Philip Hammond's budget earlier this week.
Scilly's adult social care budget in the next financial year is £1,160,000.
Chair of Community Services Cllr Fran Grottick said: "I warmly welcome any increase in adult social care funding. However, it is not just the amount but the delivery vehicle that may determine maximum benefit. If the focus is on the use of the Better Care Fund, that can be problematic as the funds are awarded at the conclusion of a project, not at the outset.
"In addition, the Council adding a percentage to Council tax bills to help fund ASC is of limited benefit because a 1% increase in our Council tax raises less than £15,000. This becomes of welcome but limited help, and, of course, impacts on our residents."
She added: "Our Council Officers and our MP Derek Thomas are continuing to press for a greater recognition of our rural challenges where economies of scale are not an option."
