What our adviser partners say

Savile Row financial services
'By offering a huge range of cash savings accounts that are accessible almost instantly, Flagstone betters client outcomes.’

Twelve Wealth Management
‘SME clients often build a large cash reserve which is held in current accounts earning zero or low interest.’

Riverfall Financial
'Cash remains a safe place for a lot of people. And, with Flagstone's offering, we feel we have a great solution that perfectly complements our overall service.'
How Flagstone
makes money
For each account you open with our bank partners through Flagstone, we receive a small share of the interest. We deduct that share before we feature any account in our platform – so the rate you see will always be the rate you receive.
We don’t charge admin, management, or platform fees.
