AIB (NI) savings rates — compare every account, plus switch offers and guides

Who they are

AIB (NI) is a commercial bank in Northern Ireland that forms part of Allied Irish Banks's UK subsidiary, AIB Group (UK) plc. The bank was created in 1991 when TSB Northern Ireland merged with the AIB Group's other interests, though its roots stretch all the way back to 1816 and the founding of the Belfast Savings Bank. It traded as First Trust Bank until rebranding as AIB (NI) in late 2019. Today it operates as a full-service high street bank serving personal and business customers across Northern Ireland, with seven branches across the region.

Savings accounts

AIB (NI) covers a decent spread of account types. The standout is the Regular Saver Account, paying 6% variable on instant-access savings from a minimum of just £10 - a genuinely strong rate for disciplined monthly savers. For those wanting to lock money away, there are Fixed Rate Savers at 3.75% for both 12 and 24 months, each requiring a £5,000 minimum. A shorter 6-month fixed option is also available, again with a £5,000 minimum. There is a Cash ISA paying 3.5% variable with instant access from £50, and an easy-access Select Account from just £1, though that carries a much lower variable rate. Rates are variable where stated and can move at any time, so always check the live figures on this page.

FSCS protection - one thing to be aware of

All AIB (NI) deposits are FSCS-protected, but the limit works slightly differently here than at most banks. AIB Group (UK) plc operates under the trading names of AIB (NI) in Northern Ireland and Allied Irish Bank (GB) and Allied Irish Bank (GB) Savings Direct in Great Britain - and the FSCS limit relates to the combined amount across all of those trading names. The protection limit across those brands is £120,000 per eligible depositor - higher than the standard £85,000 you see elsewhere. Even so, if you already hold savings with Allied Irish Bank (GB), those balances count toward the same total. Worth factoring in if you save with more than one AIB brand.

Is it right for you?

AIB (NI) makes most sense if you are based in Northern Ireland and want a long-established bank with a solid range of savings options sitting alongside your day-to-day banking. The Regular Saver rate is one of the more eye-catching on the market for that account type, and the fixed-rate products are straightforward with no bonus-rate gimmicks to watch out for. There is no current account switch offer at the time of writing. As always, the live rates shown on this page are the source of truth - check them before you decide.
