How to Compare Bank Switching Offers in the UK
A fair switching comparison deletes the excitement from the process. Start with whether you qualify, convert the offer into net first-year value, then judge whether the destination account still works when the one-off incentive is removed.
Build the eligibility filter before comparing money
Create a shortlist only from offers you can actually receive. Check previous-customer exclusions, required destination account, CASS requirement, whether the switch can go into an existing account and whether a sole or joint account changes eligibility. Current providers use materially different history tests, so a generic 'new customer' label is not precise enough.
Keep provider history in one note: accounts previously held, switch incentives previously received and relevant dates. This reduces the risk of completing an entire switch only to fail a historic-customer test that could have been identified before the application.
For this how to compare switching offers section, the control point is 'Build the eligibility filter before comparing money'. Keep the comparison sequence strict: eligibility, dated actions, first-year net value, lost old-account benefits, normal-year destination value and one downside stress test. Record the assumption used for section 1, attach the current source or saved offer terms, and test one failure case before treating the apparent value as reliable. This keeps the explanation usable when a provider changes a bonus, deadline, fee, benefit or eligibility rule without changing the broader switching process.
Convert the headline into first-year net value
Start with the cash incentive, subtract twelve months of account fees you expect to pay, then add only recurring rewards or benefits you will realistically use. If the destination account is fee-free, the arithmetic may be simple. If it is a packaged account, the fee and replacement value of insurance need separate treatment.
Then create a normal-year value with the switch payment removed. This second number prevents a £200 or £240 bonus from making an unsuitable account look permanently attractive. The method is especially important when the destination has a monthly fee, overdraft cost or travel tariff that will continue long after the cash is spent.
For this how to compare switching offers section, the control point is 'Convert the headline into first-year net value'. Keep the comparison sequence strict: eligibility, dated actions, first-year net value, lost old-account benefits, normal-year destination value and one downside stress test. Record the assumption used for section 2, attach the current source or saved offer terms, and test one failure case before treating the apparent value as reliable. This keeps the explanation usable when a provider changes a bonus, deadline, fee, benefit or eligibility rule without changing the broader switching process.
Map every qualifying condition to a date
Current offers show why a generic checklist is unsafe. Santander uses a 60-day qualification period and a Regular Saver funding condition. Nationwide uses a 28-day completion requirement plus actions within 31 days. First direct uses a 45-day window for several actions. Lloyds, NatWest and other providers use different combinations again.
Write the switch request, completion, Direct Debit, deposit, card-payment and app-login requirements in chronological order. Save evidence as each task is completed. If the provider later says the offer was not earned, you have a dated record instead of trying to reconstruct the process from memory.
For this how to compare switching offers section, the control point is 'Map every qualifying condition to a date'. Keep the comparison sequence strict: eligibility, dated actions, first-year net value, lost old-account benefits, normal-year destination value and one downside stress test. Record the assumption used for section 3, attach the current source or saved offer terms, and test one failure case before treating the apparent value as reliable. This keeps the explanation usable when a provider changes a bonus, deadline, fee, benefit or eligibility rule without changing the broader switching process.
Price the account you are giving up as well as the account you gain
The old current account may contain a fee-free overdraft, linked savings rate, reward, branch convenience or long-standing payment setup. Those lost features belong on the cost side of the comparison even though they do not appear on the switching advertisement.
Also check whether any linked saver, reward or insurance stops when the old account closes. A £200 bonus can be poor value if the switch destroys a linked benefit worth more than that over the next year. This is why 'switching value' should include the opportunity cost of closing the source account.
For this how to compare switching offers section, the control point is 'Price the account you are giving up as well as the account you gain'. Keep the comparison sequence strict: eligibility, dated actions, first-year net value, lost old-account benefits, normal-year destination value and one downside stress test. Record the assumption used for section 4, attach the current source or saved offer terms, and test one failure case before treating the apparent value as reliable. This keeps the explanation usable when a provider changes a bonus, deadline, fee, benefit or eligibility rule without changing the broader switching process.
Stress-test one missed condition and one bad month
Model the outcome if one condition is missed and the incentive becomes £0. Then model a month in which the destination account charges its fee, the reward is missed or an overdraft is used. If the account becomes clearly unattractive under normal imperfection, the headline offer is fragile.
The strongest offer is not necessarily the one with the biggest cash number. It is the one whose conditions fit your existing behaviour and whose destination account remains useful when the promotion is deleted from the spreadsheet.
For this how to compare switching offers section, the control point is 'Stress-test one missed condition and one bad month'. Keep the comparison sequence strict: eligibility, dated actions, first-year net value, lost old-account benefits, normal-year destination value and one downside stress test. Record the assumption used for section 5, attach the current source or saved offer terms, and test one failure case before treating the apparent value as reliable. This keeps the explanation usable when a provider changes a bonus, deadline, fee, benefit or eligibility rule without changing the broader switching process.
BankOfferScout editorial view
The strongest switching decision survives after the one-off promotion is deleted from the spreadsheet. We therefore rank the method around destination-account fit first and temporary incentive value second.
The editorial test for How to Compare Switching Offers is whether the choice still works under normal behaviour. Our second test is resilience: would the choice still make sense after allowing for missing a qualifying action or moving to a poor-fit destination account? That question often exposes the difference between an attractive headline and durable value.
Before acting on How to Compare Switching Offers, verify cash incentives, eligibility exclusions, pay-in rules, Direct Debit requirements, deadlines and account features using the provider switching page, incentive terms and destination-account tariff. If the answer depends on a rule outside the provider, confirm it through the Current Account Switch Service or another authoritative process source. BankOfferScout supplies the decision framework rather than freezing live product data in time.
Sources and related guides
Comparison methodology and current examples were checked on 30 September 2026 against CASS and provider switching pages. Future updates should refresh each promotion's amount, end date, historic-customer exclusions, account-fee position and required actions independently. The method should remain stable: eligibility first, dated execution second, first-year net value third and normal-year destination-account value last. Do not infer that two offers with the same headline cash use the same qualification rules or payment timing.
For this how to compare switching offers section, the control point is 'Sources and related guides'. Keep the comparison sequence strict: eligibility, dated actions, first-year net value, lost old-account benefits, normal-year destination value and one downside stress test. Record the assumption used for section 6, attach the current source or saved offer terms, and test one failure case before treating the apparent value as reliable. This keeps the explanation usable when a provider changes a bonus, deadline, fee, benefit or eligibility rule without changing the broader switching process.
