What is a Time Deposit?
A Time Deposit is a fixed-term investment that allows organisations to deposit funds for an agreed period in return for a guaranteed rate of interest. Time Deposits can provide a secure and predictable return while helping organisations manage surplus cash efficiently.
We offer Time Deposits for organisations seeking competitive, guaranteed returns on surplus funds. All Time Deposit products are with National Counties Building Society, our legal entity. Family Building Society is a trading name of National Counties Building Society.
Key Features

- Deposit terms available from one month to five years
- Investments from £250,000 to £25 million
- Guaranteed returns for the duration of the deposit term
- Available to a wide range of UK-based organisations and institutions
- Competitive rates negotiated according to market conditions, deposit amount and term.
We offer a range of Time Deposits through National Counties Building Society, with rates of interest that closely reflect those available in the London money markets.
Whether your priority is guaranteed returns or a tailored investment solution, we can arrange deposits from one month to five years to meet the needs of businesses, corporates, associations and other organisations.
