Our verdict

Lightyear’s Cash ISA currently pays 3.75% AER, designed to closely follow the Bank of England base rate. The account is fully flexible, has no account fees, no withdrawal penalties and no minimum deposit, and avoids short-term bonus rates that later drop. Savings are held across UK banks and qualifying money market funds, with FSCS protection applying to cash held in partner banks.

How does the Lightyear Cash ISA compare with rivals?

The Lightyear Cash ISA remains competitive thanks to its simple pricing, flexible terms and rate that tracks the Bank of England base rate, currently 3.75% AER (variable). You can withdraw and replace money without affecting your £20,000 ISA allowance, and there are no account fees, transfer charges or short-term bonus rates that later drop.

While the rate is solid, it now sits more in the middle of the market in 2026, with some rivals like Tembo offering slightly higher easy-access ISA rates. However, many of those come with bonus periods, withdrawal limits or tiered rates that can fall after the first year. Lightyear’s appeal is its straightforward approach: one variable rate that follows the base rate and no penalties for withdrawals.

Lightyear UK is authorised and regulated by the Financial Conduct Authority (FCA). FSCS protection applies to cash held with partner banks (typically up to £85,000 per person per bank), though this protection does not apply to money held in qualifying money market funds.

In this review, we look at the Lightyear Cash ISA and compare it with the Cash ISAs offered by other providers in 2026.

What is the Lightyear Cash ISA?

Lightyear, the investment platform founded by former Wise executives Martin Sokk and Mihkel Aamer, offers both a Cash ISA and a Stocks & Shares ISA as part of its UK investing app.

ISAs allow you to save up to £20,000 per tax year (6 April to 5 April) without paying tax on the interest you earn. A Cash ISA is designed for holding savings rather than investing in markets, making it a lower-risk option, although long-term returns are typically lower than investing.

Lightyear Cash ISA Alternatives

You can get much better returns if you choose a stocks and shares ISA where your money is invested in the stock market.
