Top up your Cash ISA and earn up to £500
How it works
1. Increase your cash ISA balance
Increase your Cash ISA balance by at least £20,000 before 31 May 2026 and you'll qualify for a bonus. The more you grow, the more you earn (see reward table below for details).
Eligible increases includes ISA transfers in and new ISA subscriptions.
2. Hold your balance
Maintain your increased balance until 31 July to stay eligible. Any withdrawals or transfers out made during this period may impact the level of ISA Reward that you qualify for.
3. Receive your reward
If you qualify, we’ll pay your ISA Reward by 15 August 2026. Your ISA Reward will either be paid into your Easy Access Savings Account, if you have one, or your linked account if you don’t.
This offer may close early if demand is high. We will contact you directly if this happens.
Other important information
Your ISA Reward tier is determined by your total balance increase as at 23.59 on 31 May. Any funding received after this date will not count towards a higher tier. If you withdraw or transfer funds out before 31 July, your net balance increase will reduce and your bonus may be adjusted or removed.
A transfer in will only count towards your total balance increase if the funds are received by Monument before 23:59 on 31 May 2026. To allow sufficient time for the transfer to complete, a transfer request should be received by us by 23:59 on 11 May 2026 so your funds are received in time.
The ISA Reward is subject to the ISA Reward Terms, which set out the full details. Our FAQs include additional information such as how rewards are calculated.
Only clients who have opened a Monument savings account before 6 April 2026 are eligible for the ISA Reward.
You must have an open Monument savings account at the time the ISA Reward is paid.
Eligible deposits are protected up to the maximum limit of £120,000 per person per bank by the Financial Services Compensation Scheme (FSCS).
