Quick review
Wondering whether Lightyear is worth it beyond the bonus? Here is our honest take.
A clean, no-frills broker built by ex-Wise people, with Quidsy showing a £15 cashback offer right now. Suits cost-conscious investors who already know what they want to buy, especially for an ISA. Watch-out: the Vaults product is a money market fund, so cash sitting in there is not FSCS-protected.
Chris' verdictYour personal guide, QuidsyI think Lightyear is worth a look if you want a no-frills, low-cost platform to hold stocks, ETFs, or an ISA without paying through the nose. The March 2026 pricing changes pushed it firmly into commission-free territory across UK, US, and EU markets, and the Stocks & Shares ISA is genuinely cheaper than the big incumbents over the long run.
The £15 Quidco cashback offer is a quick win if you'd open an account anyway. Deposit £5 or more into your General Investment Account through Quidco, hold it for about eight weeks, and Quidco pays the £15 cash. Your £5 stays yours to keep, withdraw, or move into a Vault to earn a bit of interest while you decide what to invest in.
The honest caveats: it's still a smaller platform than the big brokers, the research tools are basic, and the Vaults product is a money market fund not a savings account, so your cash there isn't FSCS-protected the way it would be in a normal bank. If those things matter to you, treat Lightyear as a low-cost secondary platform rather than your main account. If they don't, the value-for-money is hard to beat.
Lightyear UK Ltd is authorised and regulated by the Financial Conduct Authority (FRN 987226). Eligible cash held with partner banks (Citibank and NatWest) is FSCS-protected up to £120,000. Investments and Vaults are not FSCS-protected. Capital at risk.
