Regular Savings Accounts for UK Expats: Onshore and Offshore Options

UK-authorised banks and building societies (authorised by the Prudential Regulation Authority) are covered by the FSCS. From 1 December 2025 the FSCS deposit protection limit is £120,000 per eligible person per authorised firm. Non-resident UK nationals can hold FSCS-protected deposits: what matters for eligibility is that the firm is PRA-authorised, not that the depositor lives in the UK. The £120,000 limit applies per banking group: accounts across multiple banks sharing the same licence count toward a single £120,000 limit. FSCS also provides temporary high balance protection of up to £1.4 million for qualifying life events (such as a property sale or inheritance) for up to six months. Source: FSCS fscs.org.uk.

Banks based in offshore financial centres (Isle of Man, Jersey, Guernsey) are not PRA-authorised. Each jurisdiction operates its own depositor compensation scheme with different limits. The Isle of Man Depositors' Compensation Scheme protects up to £50,000 per eligible person per covered bank (with a lower limit for companies, trusts, and charities), subject to a scheme cap of £100 million per five-year period. The Jersey Depositors' Compensation Scheme protects up to £50,000 per depositor per Jersey banking group for personal depositors and charities; from April 2026, the £100 million scheme cap is being removed. The Guernsey Banking Deposit Compensation Scheme protects up to £50,000 per qualifying depositor per bank, with a £100 million scheme cap. All three are separate schemes: protections cannot be combined or aggregated with FSCS. Source: FSCS; Isle of Man FSA; Jersey DCS jerseydcs.je; Guernsey DCS dcs.gg.

Once a UK national becomes non-UK resident, they cannot make further contributions to an ISA. The sole exception is Crown employees working overseas and their spouses or civil partners. An existing ISA remains open and existing holdings retain UK tax relief. If the holder later returns to the UK and regains UK residence, contributions can resume subject to the annual allowance.

UK-source interest (from a UK bank) is generally taxable UK income for non-residents. Under the section 811 ITA 2007 restriction, the UK tax liability is limited to the tax, if any, already deducted at source: where no tax is deducted at source, there may be no further UK tax due on that interest, depending on the individual's full position. Whether the Personal Savings Allowance (PSA) is available to non-residents against UK-source interest is a question whose answer depends on individual circumstances and HMRC guidance that should be confirmed with a regulated specialist or directly from HMRC: this page does not assert the PSA is or is not available to non-residents. Interest from accounts in the Isle of Man, Jersey, or Guernsey is generally not UK-source income: HMRC's position is that a non-UK resident's UK tax liability is generally limited to UK-source income. Offshore interest is therefore generally not subject to UK income tax for a non-resident, but it will normally be taxable in the country of residence, and under CRS the offshore bank reports account data to that country's tax authority. Double taxation agreements may reduce the effective UK rate on UK-source interest; relief must be claimed via HMRC HS304. Source: HMRC SAIM1170; HMRC HS304.
