TL;DR
UK current accounts handle day-to-day transactions; savings accounts earn interest; ISAs combine savings with a tax-free wrapper. This guide covers the differences, FSCS protection, and how the GBP 20,000 ISA allowance interacts with savings.
Key facts
- Current accounts: debit card, direct debits, Faster Payments, often no interest.
- Savings accounts: interest-bearing, may have notice periods or fixed terms.
- ISAs: GBP 20,000 annual allowance, tax-free on interest, dividends and gains.
- All three covered by FSCS up to GBP 85,000 per authorisation.
- Personal Savings Allowance gives GBP 1,000 (basic) of tax-free non-ISA savings interest.
- ISA allowance resets each 6 April; cannot be carried forward.
- Joint ISAs are not permitted; each individual has their own GBP 20,000.
- Lifetime ISA limit GBP 4,000 is within the GBP 20,000 overall.
UK savers typically split money across three account types: a current account for day-to-day transactions, a savings account for easy-access or fixed-term saving outside the tax wrapper, and an ISA for tax-free saving up to the annual GBP 20,000 allowance. Each has a different purpose, different rules, and different tax treatment.
This guide covers how each account works, when each is appropriate, and how the Personal Savings Allowance and the ISA allowance interact for taxpayers at different bands.
Current accounts: the transaction hub
A current account is the operational bank account: it receives salary or self-employment income, pays direct debits and standing orders, provides a debit card for everyday spending, and supports Faster Payments and BACS for sending money. Interest is typically not paid on current accounts (some pay 0.5% to 2% AER on credit balances up to a cap, often as part of an account-feature package).
The features expected: debit card with chip and pin, contactless and online use; ATM access for cash withdrawals; ability to receive and send Faster Payments; direct debit and standing order setup; online banking and app access; overdraft facility (subject to FCA affordability assessment); FSCS protection up to GBP 85,000.
Most current accounts are free for standard use. Packaged accounts charge GBP 10 to GBP 25 a month for added benefits (travel insurance, mobile phone insurance, breakdown cover). Basic bank accounts are a stripped-down current account without overdraft, available under PAR 2015 to legally resident applicants who cannot or do not want a standard account.
Worked example: a customer holds their main current account with a fintech bank, receiving salary monthly and using the debit card for everyday spending. Average balance after monthly outgoings GBP 200 to GBP 1,500. The current account is not the right place to keep large balances long-term because it earns little or no interest; transferring to a savings account or ISA above a working buffer is the sensible step.
Savings accounts: easy access, notice, fixed
Savings accounts come in several forms. Easy access (instant access) accounts allow withdrawals on demand, typically at lower rates because the bank cannot rely on the deposit being available for a fixed period. Notice accounts require 30, 60, or 90 days' notice for withdrawals and pay slightly higher rates. Fixed-rate bonds lock the money for a specified term (1 to 5 years) at a fixed rate, typically the highest rates available at any given time.
Regular saver accounts pay higher headline rates on small monthly deposits (typically GBP 50 to GBP 500 a month, capped at an annual limit). Rates of 5% to 7% AER are common but apply to a small balance, so the absolute interest is modest.
Interest on non-ISA savings is taxable as savings income. The Personal Savings Allowance gives GBP 1,000 of tax-free interest to basic-rate taxpayers, GBP 500 to higher-rate, and nil to additional-rate. Above the PSA, interest is taxed at the band rate. Banks report interest annually to HMRC; PAYE codes are normally adjusted to collect any tax due.
Worked example: a basic-rate saver holds GBP 25,000 in an easy access account at 4.5% AER. Annual interest GBP 1,125. PSA covers GBP 1,000; the remaining GBP 125 is taxed at 20% = GBP 25. Net interest GBP 1,100. Compared with the same GBP 25,000 in a Cash ISA at 4.3% AER (slightly lower rate but tax-free), interest would be GBP 1,075. The non-ISA route wins by GBP 25 in this example because the rate difference exceeds the tax on the small slice above PSA.
ISAs: the tax-free wrapper
An Individual Savings Account is a tax-free wrapper around savings or investments. Interest, dividends and capital gains within an ISA are exempt from UK income tax and capital gains tax, and do not need to be reported on the Self-Assessment return. The annual ISA allowance is GBP 20,000 for 2026/27 across all ISA types combined.
ISA types: Cash ISA (savings-style account, interest bearing), Stocks and Shares ISA (investments in shares, funds, ETFs), Innovative Finance ISA (peer-to-peer lending), Lifetime ISA (LISA - GBP 4,000 a year sub-limit with 25% government bonus for qualifying first-home purchase or retirement at 60), Junior ISA (for children under 18, separate GBP 9,000 annual allowance).
The GBP 20,000 allowance can be split across types (e.g. GBP 16,000 cash + GBP 4,000 LISA). The LISA sub-limit nests within the GBP 20,000 total. Each individual has their own allowance; ISAs cannot be joint. The allowance resets each 6 April and cannot be carried forward unused.
Worked example: a basic-rate saver with GBP 30,000 of savings has interest above PSA. Moving GBP 20,000 into a Cash ISA on 6 April covers the new year's allowance; the remaining GBP 10,000 stays in the non-ISA easy access account. The following 6 April another GBP 20,000 moves into the same or another ISA, gradually shifting the full balance into the tax-free wrapper over time.
FSCS protection across account types
FSCS protection covers eligible deposits up to GBP 85,000 per person per banking authorisation, across all account types held with the same authorisation combined. A customer with GBP 30,000 in a current account, GBP 25,000 in a savings account, and GBP 20,000 in a Cash ISA at the same bank has total deposits of GBP 75,000, all protected.
Where the same customer holds GBP 60,000 in a current account plus GBP 30,000 in a Cash ISA at the same bank, total deposits are GBP 90,000 - GBP 5,000 above the cap. The GBP 5,000 above the cap is unprotected. Splitting across truly separate authorisations (a different bank with a different PRA authorisation) restores full protection.
Stocks and Shares ISAs are protected under FSCS investment cover (GBP 85,000 per person per firm) rather than the deposit cover. The protection covers loss caused by firm failure, not loss caused by investment performance. Innovative Finance ISAs may have limited or no FSCS protection depending on the platform and the underlying investments; peer-to-peer lending carries default risk on the borrower side.
Practical action: for customers with deposits approaching GBP 85,000 at a single bank, mapping the current account, savings, and ISA holdings against the cap matters. Where the cap will be exceeded, splitting to a second bank with a different authorisation is the simple step. NS&I products are Treasury-backed and outside the FSCS cap structure entirely.
Which account for which purpose
Current account: working capital - the buffer between salary and outgoings, the source of debit card spending, and the destination for incoming payments. Typically a GBP 200 to GBP 2,000 average balance after monthly outgoings clear.
Savings account: short-term saving for goals within 1 to 3 years (a holiday, a wedding, an emergency fund), or for amounts above the ISA allowance that need to remain accessible. Easy access for emergency funds; fixed-rate bonds for committed savings where the rate uplift justifies the lock-up.
ISA: tax-free savings or investment growth over the long term. The allowance is use-it-or-lose-it each year, so maximising the ISA contribution before adding to non-ISA savings makes sense for most savers. For stocks and shares investing, the ISA wrapper saves dividend tax (8.75% to 39.35% above the GBP 500 allowance) and capital gains tax (18% / 24% above the GBP 3,000 AEA).
Worked example: a couple in their thirties holds: joint current account with Monzo (working capital, GBP 1,500 average); easy access savings with Chase (GBP 8,000 emergency fund); Cash ISAs each (GBP 20,000 each in the current year, building over time toward GBP 100,000 each); workplace pensions for retirement. The structure balances liquidity for emergencies, tax efficiency on the savings, and pension contribution for the long-term.

Frequently asked questions
What's the main difference between a current and savings account?
Current accounts handle day-to-day transactions: receiving income, paying direct debits, debit card use, Faster Payments. They typically pay little or no interest. Savings accounts pay interest on the balance but may have notice periods, fixed terms, or withdrawal restrictions. Both have FSCS protection up to GBP 85,000 per authorisation. A typical setup is to keep a working buffer in the current account and move surplus to savings or ISAs for higher interest.
How much can I put in an ISA each year?
GBP 20,000 a year across all ISA types combined for 2026/27. The allowance resets each 6 April and cannot be carried forward unused. It can be split: e.g. GBP 16,000 Cash ISA plus GBP 4,000 Lifetime ISA, or GBP 20,000 Stocks and Shares ISA only. The Lifetime ISA limit of GBP 4,000 is within the GBP 20,000 total, not separate. Junior ISAs for under-18s have their own separate GBP 9,000 allowance, paid by parents or guardians.
Do I pay tax on savings interest?
Yes above the Personal Savings Allowance. Basic-rate taxpayers get GBP 1,000 of tax-free interest a year; higher-rate get GBP 500; additional-rate get nil. Above the PSA, interest is taxed at the marginal income tax rate. ISA interest is entirely tax-free regardless of amount. The Starting Rate for Savings adds a GBP 5,000 band at 0% but is tapered against other income, useful only for taxpayers with low earnings and significant interest.
Are stocks and shares ISAs safer than savings ISAs?
Different risks. A Cash ISA is a savings account in a tax-free wrapper, with FSCS deposit protection up to GBP 85,000 against bank failure. A Stocks and Shares ISA holds investments (shares, funds, ETFs) with market risk. The investment can fall in value, and the FSCS investment protection covers loss caused by firm failure, not investment performance. Over long periods (10+ years) Stocks and Shares ISAs typically outperform Cash ISAs but at the cost of short-term volatility.
Can I have multiple ISAs at the same time?
Yes from 6 April 2024. The rule changed to allow contributions to multiple ISAs of the same type in the same tax year, provided the total across all stays within GBP 20,000. Previously a saver could only contribute to one of each ISA type per year. Transfers of prior-year ISAs to a new provider remain available and do not count toward the current year's allowance. Lifetime ISAs are still restricted to one per person.
