You know that feeling when you look at something you set up months ago and suddenly think, "Wait... is this still the right call?" That's exactly where you should be right now. March is your last realistic window to audit your entire banking strategy before the tax year flips on April 5 and Easter chaos disrupts cooling-off timelines.
I'm not just talking about glancing at your balance. I mean a proper audit—the kind where you ask hard questions about whether every account, bonus, and strategy you're using still makes sense in 2025. Interest rates have shifted. New offers have landed. Some accounts you opened might be past their peak earning window. And in exactly 19 days, the tax year resets, which changes everything about your allowance planning.
This is the post where we walk through exactly how to do that audit, what to look for, and most importantly, whether the time investment in switching actually makes sense right now.
The Case for Auditing Now (And Why Waiting Gets Expensive)
If you switched accounts last autumn or early winter, your cooling-off period is either just ending or already ended. That means right now—in mid-March—you're probably eligible to switch again. Not in April. Not in May. Now.
Here's the brutal math: if you find that your current account is earning 0.5% while another bank offers 1.0% with a £1,250 switching bonus, waiting two weeks means you lose that bonus altogether. You also lose two weeks of the higher interest rate. In a tax year where most people are earning less than £150 from their savings accounts anyway, a £1,250 one-time bonus is genuinely significant.
But there's another reason March matters: the tax year ends on April 5. Between now and then, your Personal Savings Allowance is at its absolute maximum. Any interest you earn from now until April 5 comes fresh from this year's allowance—which will reset to zero on April 6. (Technically April 6 is when it resets, but let's be practical: you need the switch completed by April 5 at latest.)
Easter creates a third wrinkle. Easter Monday is April 7 this year, which means the Monday following the tax year end. If your switch is still in progress during Easter, you might hit cooling-off delays. The BCWYC switch service normally takes 7 working days, but throw a 4-day bank holiday weekend into that and you're looking at 11+ calendar days. If you're not careful, your cooling-off period for this new account stretches into early May, pinning you in place right when other offers might look attractive.
The simple version: audit now, switch by March 24 at latest if you want to close everything cleanly before April 5.
The Four Areas to Audit
Rather than overwhelming you with 47 different metrics, let's focus on four specific areas that actually affect your earning power.
1. Current Account Interest Rates
This is the baseline. Your main current account probably earns somewhere between 0% and 2% interest, depending on the balance or the terms. A lot of people are still sitting in accounts from 2023 that offered 1% and now pay 0.5%, simply because they haven't looked.
Check the live offers page to see what's available right now. As of mid-March 2025, we're seeing accounts paying between 0% and 2% depending on criteria like minimum deposits or account activity. NatWest and RBS are still pushing hard at £1,250 bonuses. Santander is offering £500. HSBC, TSB, and First Direct are all at £175.
The question isn't "Is there a better rate out there?" The answer is always yes to that. The real question is: "Is the bonus + the rate difference worth the switching hassle?"
If you're sitting in a 0.5% account with £10,000, you're earning £50 per year. A switch to a 1.0% account would earn you £100 per year—a gain of £50. Add a £175 bonus and you've just earned £225 in year one, £50 per year thereafter. That's worth doing.
But if you're in a 1.5% account earning £150 per year on the same £10,000, and the best available is 1.0% with a £175 bonus... you'd earn £100 + £175 = £275 in year one, but then drop to £100 per year. It's still worth it once, but now you're in a cycle where you're switching every 12-18 months instead of every 2-3 years. That might be sustainable for you, or it might be exhausting. Be honest about which person you are.
2. Your Switch Bonus Timeline
If you switched in the last 90 days, your bonus might not have hit your account yet. Some banks take 30 days. Others take 90. If you switched around Christmas or early January, that bonus should be here now—and if it's not, that's worth a phone call to sort out.
For planning purposes: if you complete a switch by March 24, the bonus lands around mid-May. That's still in the current tax year if it hits before April 5... wait, no. April 5 is when the tax year ends. Mid-May is next year's tax year. So any bonus from a switch completed this week is taxable in 2025/26. That matters if you're close to your Personal Savings Allowance limit.
Actually, let me be precise: interest earned between now and April 5 at 11:59 PM counts toward this year's allowance. Any bonus that hits after April 5 is next year's. So if you're already at your allowance limit for 2024/25, a switch completed this week might be the wrong call—the bonus becomes taxable income instead of a tax-free gift.
Check your Personal Savings Allowance remaining headroom. It's the unsung hero of March planning.
3. Regular Saver Accounts
If you've been feeding money into a regular saver at 5%, 6%, or 7%, you might be sitting in an account from 2021-2023 when rates were genuinely fantastic. Current regular savers are paying 3%-4% in most cases—still brilliant, but notably different.
Here's the audit question: when does your current regular saver term end?
If it ends in June, you've got two months left to decide whether to recommit or move. If it ends in November, you might be fine where you are. But if you're about to restart a regular saver in April (a natural time to begin, with the tax year), now's the moment to shop around. Some banks are offering 4.5%+ on new regular saver accounts starting April 1.
The mathematical edge of a regular saver is that it compounds throughout the year. £250 per month at 4% earns you roughly £65 in interest. That's not phone-call-worthy money, but it's consistent and tax-free. The audit here is simple: are you actually going to feed a regular saver over the next 12 months? If yes, lock in the best rate you can find now, while the offers are visible.
4. Your 0% Credit Card Strategy (If You Stooze)
If you're using stoozing—parking money on a 0% credit card and earning interest in a savings account—now's the time to check whether your card is still alive.
Credit card providers are quietly cutting 0% balance transfer offers. The golden 18-27 month deals are vanishing in favour of 12-15 month terms. If your card is approaching its expiry, you need to know now, not in June when you suddenly realise the interest is ticking.
Also: check the interest rate on your underlying savings account. If you parked that money in a 1.5% easy-access account two years ago and never revisited it, you might now be earning 0.5% on the same account. The opportunity cost is real.
Red Flags: Time to Switch
Any of these should trigger a switch:
- Your current account earns 0% or less. This is 2025. There's literally no reason.
- You've been in the same account for 18+ months. Bonuses reset, rates shift, and patience isn't rewarded in banking.
- Your regular saver term is within 60 days of ending. Start shopping now, not the week it ends.
- Your 0% credit card balance transfer is less than 6 months from expiry. You need runway to get a new card approved and debt shifted.
- Your easy-access savings account pays less than 1.0%. The whole point of easy-access is flexibility. Don't sacrifice rate for it.
- You've hit your Personal Savings Allowance limit. Any additional interest becomes taxable. A bonus is still tax-free, but interest isn't.
What Actually Takes 19 Days?
Let's be real about the calendar. Today is March 17. Easter is March 30 this year (yes, early). April 5 is when the tax year ends. Here's what you can realistically complete:
March 17-24: You can start a switch and realistically see it complete by April 7-8 (allowing for Easter delays). The bonus lands in mid-May (next tax year). This is fine if you're not bumping against your Personal Savings Allowance.
March 25-31: You're cutting it very close. A switch starting today might not complete until April 7-10, and cooling-off periods could stretch into mid-April. The bonus is definitely next tax year. The interest you'll earn is either minimal or at risk of not clearing before tax year end.
April 1-5: Don't bother. The tax year is ending, cooling-off timelines are messy, and you're better off waiting until April 6 to plan strategically.
If you want to be genuinely cautious, think of March 24 as your hard deadline. Switches started by then are almost certain to complete cleanly before Easter disrupts everything.
How to Prioritise (When You Can't Do Everything)
If auditing your entire banking stack feels overwhelming, here's the priority order:
- Current account: This is your primary earning engine. If it's paying less than 1.0%, or if you're eligible to switch (haven't moved accounts in 18+ months), this is priority one.
- Easy-access savings: If you have cash sitting in an easy-access account paying 0.5%, shift it to one paying 1.0%+ immediately. The interest difference alone justifies the 10 minutes it takes.
- Regular saver: Only if your current account is sorted and your regular saver term is ending in the next 90 days.
- 0% credit card: Only if your current card is within 6 months of expiry. Otherwise, you've got time.
Common Questions
Should I switch if I've already earned my Personal Savings Allowance limit this year? Honestly? No. The bonus becomes income and gets taxed. The interest you'd earn on the new account is also taxed. Wait until April 6 to switch, when you've got a fresh £1,000 (or £500) allowance. One month of delay is worth the tax saving.
Does the switch really take 7 working days, or can it be faster? The BCWYC switch service legally takes 7 working days. In practice, banks usually complete it faster—sometimes 3-4 working days. But Easter is in the way this year, so assume 10-11 calendar days from now until April 7. The only way to speed it up is to switch immediately, like today.
What if I start a switch and then my current bank offers me a better deal mid-way through? You can't stop a switch once it's started and the 7-day window opens. You could leave the switch running and then separately switch away from the new bank once you're eligible, but now you're in a three-way dance. It's cleaner to make your decision first, then commit.
Can I switch if I have direct debits set up? Yes. The switch service transfers your direct debits automatically, usually within the 7-day window. By day 7, everything is moved. It's actually one of the least friction points of switching now.
Is now actually the right time, or should I wait until April? If you're under your Personal Savings Allowance and haven't switched in 18+ months, now is better. You keep the bonus in this tax year. If you're maxed on your allowance, wait five days until April 6. Either way, the next 24 hours are less important than making a decision—indecision is the expensive thing.
