What it is
Instant Saver is a savings pot attached to your Tide membership. Money moves in and out from your business current account, interest accrues on the balance, and access is instant rather than notice-based. It exists so that reserves — a VAT set-aside, a tax pot, retained profit you are not yet distributing — earn something instead of sitting idle in the current account earning nothing.
The interest rate is variable and set by Tide, so we do not print a figure here; rates on instant-access products move with the wider interest rate environment and Tide's own commercial decisions, and any number we published would risk being wrong within weeks. Check the current rate on Tide's own pages before you plan around it, and be aware that a variable rate can fall as well as rise while your money sits in the pot.
How it fits alongside the current account
Unlike a fixed-term or notice savings product, Instant Saver does not lock your money away. You can move funds back to your current account the same way you moved them in, which makes it suited to money you want to keep separate for discipline reasons — so it is not accidentally spent — rather than money you are deliberately committing for a fixed period. For a limited company setting aside VAT or corporation tax between filing dates, that combination of separation and instant access is often more useful than the interest rate itself.
The campaign requirement
For the £125 step of the REFER200 campaign, you must deposit at least £5,000 into Tide Instant Saver within 7 days of account opening and keep it there for one month. Two things follow from that wording: the money has to be available and ready to transfer almost immediately after your account is approved, and it has to be money you genuinely will not need for a month, because dipping below the required balance during the hold typically breaks the condition.
This is a different, and separate, mechanism from Tide's own public Refer a Friend programme, which rewards existing customers for introducing new ones. REFER200 is our site's own tracked campaign; do not assume terms, timings or amounts carry across between the two.
Common mistakes on this step
- Missing the seven-day window because the transfer was scheduled for a future date rather than made immediately.
- Funding with slightly under £5,000 after a transfer fee or rounding error — leave headroom above the threshold rather than funding to the exact penny.
- Dipping into the balance during the 30-day holding period for an unrelated payment, which normally breaks the condition even if the balance is topped back up later.
- Assuming the 30-day card-spend window for the £75 step also applies here — it does not; the funding window for this step is much shorter, and mixing the two up is one of the most common reasons readers tell us they missed a step.
- Treating the interest earned as the main incentive. Over a one-month hold, the £125 reward will typically dwarf whatever interest the balance earns in that period, so the interest is a bonus, not the reason to do this.
Should you do it?
If £5,000 is genuinely idle for a month — money you were going to leave in a low- or no-interest account anyway — then £125 is an exceptional return for parking it and doing nothing further. If that £5,000 is your VAT bill due in three weeks, or working capital you might need for stock or payroll, do not chase this step; pursue the £75 card-spend step instead and leave Instant Saver alone. Attempting the savings step and failing partway costs you the reward entirely and may leave you short of cash when you need it, which is a worse outcome than not attempting it at all.
What happens to the money afterwards
Once the 30-day hold is satisfied, there is no requirement to keep the balance in Instant Saver. Many businesses use the pot on an ongoing basis regardless of the campaign, since instant access to a segregated tax reserve is useful in its own right; others move the funds back to the current account or elsewhere once the campaign condition is met. Either is fine — the campaign only governs the 30-day period itself, not what you do with the money after.
