Who is eligible for this offer?

This promotion is open to all new and existing Chip customers who meet the qualifying criteria. You must be over 18, a UK tax resident, and hold a Chip account.

‍

How do I qualify for the Smart Cash ISA boosted rate?

To qualify, you need to make new ISA deposits in the 2026/27 tax year into any Chip ISA between 6 April 2026 and 23:59 on 30 April 2026.

Either:

• Deposit at least £20,000 to receive a 0.75% AER boost to your Smart Cash ISA;
• Or; Deposit at least £10,000 to receive a 0.25% AER boost to your Smart Cash ISA

You’ll also need an open Smart Cash ISA to receive the boosted rate. Your rate boost is only paid on your first £20,000 of balance in your Smart Cash ISA.

‍

Can I split my deposits across different Chip ISAs?

Yes. You can deposit into any combination of Chip ISAs (Cash ISA, Smart Cash ISA, Stocks & Shares ISA). As long as your total qualifying deposits reach £10,000 or £20,000, you’ll qualify for the relevant boost tier.

‍

Do transfers from previous tax years count?

No. Only new deposits made in the 2026/27 tax year qualify. Transfers of ISA funds from previous tax years are not included.

‍

Do withdrawals affect my eligibility?

Yes. Any settled withdrawals made from your Chip ISAs before 23:59 on 30 April 2026 will be deducted from your qualifying deposit total.

‍

When do I need to make my deposit?

You must initiate your deposit before 23:59 on 30 April 2026. Deposits initiated before this deadline will count, even if they arrive shortly after.

‍

When will I receive my rate boost?

If you meet the criteria, your boosted rate will be automatically applied to your Smart Cash ISA on 1 May 2026.

‍

How long will the boosted rate last?

Your rate boost will last for 12 months (365 days) from 1 May 2026. After this period, your rate will revert to the standard Smart Cash ISA variable rate.

Please note that the Smart Cash ISA calculates interest daily, and pays interest annually on the anniversary of the opening of your Smart Cash ISA.

‍

What balance does the boost apply to?

The boosted rate only applies to the first £20,000 held in your Smart Cash ISA. You’ll continue to earn the standard tracker rate, currently 3.75% AER (variable tracker) on any balances over £20,000. 

For example, if you have £50,000 in your Smart Cash ISA, the first £20,000 will earn the boosted rate, and the remaining £30,000 will earn the Smart Cash ISA standard variable rate.

‍

Can I receive both boost tiers?

No. You can only receive one boost. If you qualify for the higher tier (£20,000), this will apply instead of the lower tier.

‍

Do I need to open a Smart Cash ISA?

Yes, if you don’t already have one. The boosted rate is applied to your Smart Cash ISA, so you’ll need an active account to receive it.

‍

What is the current Smart Cash ISA rate?

As of 6 April 2026, the standard Smart Cash ISA rate is 3.75% AER (variable tracker), which tracks the Bank of England base rate. Your boost is added on top of this rate.
