UK savings strategy: a sensible default

A practical UK savings stack looks like this: keep three to six months of essential outgoings in an easy-access account; fill your annual £20,000 ISA allowance if you have surplus and your interest is close to your Personal Savings Allowance; and ladder fixed-rate bonds for anything you can lock away for 12 or 24 months. That order protects access to emergency money first, then tax efficiency, then yield.

Be wary of introductory bonus rates. Several UK savings accounts headline at 5% but drop to 1.5% after twelve months. The platforms rarely warn you on the day the rate falls. Set a calendar reminder for one month before any bonus period ends and switch — it is a five-minute job that protects two or three percentage points of yield.

FSCS protection covers up to £85,000 per banking licence per person. If you have more than £85,000 in savings, split it across separate licences (note: some banks share licences — for example Halifax and Bank of Scotland share one). Joint accounts give two people £170,000 of cover at the same licence.

Frequently asked questions

What is the Personal Savings Allowance?
Basic-rate UK taxpayers can earn £1,000 of savings interest a year tax-free. Higher-rate taxpayers get £500. Additional-rate (45%) taxpayers get £0. The allowance applies across all non-ISA accounts combined — interest above it is taxed at your marginal rate.
What is the 2025/26 ISA allowance?
£20,000 per UK adult per tax year — across Cash, Stocks & Shares, Innovative Finance and Lifetime ISAs combined. The Lifetime ISA has its own £4,000 sub-limit. Unused allowance does not roll over.
Are UK savings accounts safe?
UK-authorised savings accounts are protected by the Financial Services Compensation Scheme up to £85,000 per banking licence per person. If the bank fails, the FSCS refunds you within seven days. Check that the bank holds a UK banking licence — some app-only providers operate under e-money licences with much weaker protection.
Should I split savings between fixed and easy-access?
For most UK savers, yes. Keep 3–6 months of essential outgoings easy-access for emergencies, then move surplus to fixed-rate bonds to lock in a higher yield. The split protects access to money you may genuinely need while still earning the higher rate on the rest.
Can I open multiple Cash ISAs in the same tax year?
Yes — from 6 April 2024 the UK relaxed the one-ISA-per-tax-year rule for Cash ISAs (and other ISA types except Lifetime ISA). You can split your £20,000 allowance across multiple providers and accounts. Each must still be inside the £20,000 total.
