What We Cover

Three verticals, each covering a different way to grow or protect your money. Investment apps for portfolio building, savings accounts for putting idle cash to work, and P2P lending for those comfortable with higher risk in exchange for higher yield.

Interest rates remain elevated in 2026. A high-yield savings account can earn you 3.75-4.50% easy access or up to 4.90% fixed on cash you would otherwise leave sitting in a current account earning next to nothing. All platforms below are covered by national deposit protection schemes.

🔗 P2P Lending
All Reviews →

Peer-to-peer lending can generate yields well above what savings accounts offer — but this is not a like-for-like comparison. P2P platforms are not banks, your capital is at risk, and loan originator defaults are a real possibility. Read our full reviews before investing.

⚠ P2P lending is not covered by deposit protection schemes. Your capital is at risk. Past yields are not a guarantee of future returns.

From the Research Desk
Guide Investment App vs Broker: What's the Difference and Which Do You Actually Need?
Two very different products. One for building a long-term portfolio. One for active trading. Most people need the first, not the second.
Guide P2P Lending: Higher Yields, Real Risks, and How to Do It Right
How P2P lending actually works, where the risk really sits, and how to build a portfolio that earns the yield without taking unnecessary exposure.
Guide High-Yield Savings Accounts: Are They Worth It and Which Should You Choose?
Most people leave cash earning next to nothing. High-yield savings accounts pay 3-5% with the same deposit protection. Here is what to open and why.
Frequently Asked Questions
Investment apps are consumer-facing, phone-first platforms designed for long-term portfolio building. They typically offer commission-free trading in stocks and ETFs, simple interfaces, and low or zero minimum deposits. Traditional brokers are aimed at more active traders and often offer access to more complex instruments like options, futures, and CFDs. If you want to invest regularly in a diversified portfolio of stocks and funds, an investment app is usually the better starting point.
Yes, provided the platform is covered by your country's deposit protection scheme. In the UK, the FSCS protects up to £120,000 per person per institution (increased from £85,000 in December 2025). In the US, the FDIC protects up to $250,000. All savings account platforms we review are covered by one of these schemes. P2P lending platforms are not covered by deposit protection — that is a fundamentally different risk profile.
P2P lending platforms connect investors directly with borrowers. As an investor, you lend money to multiple borrowers and receive interest payments in return. The platforms handle origination, credit assessment, and collections. Returns of 6-12% are typical. The risk is that borrowers can default and, more critically, that loan originators or platforms themselves can fail — unlike a savings account, your capital is not protected by any government scheme.
Most modern investment apps allow you to start with as little as £1 or $1, thanks to fractional shares. Trading 212 and Robinhood both support fractional investing from very small amounts. For high-yield savings accounts, most platforms have minimum deposits between £0 and £50. The more important question is not how much you need to start, but how much you can invest consistently over time.
"Commission-free" does not always mean free. The most common hidden costs are: foreign exchange (FX) fees when buying shares in a different currency; platform fees charged as a monthly subscription; and bid-ask spreads on less liquid assets. Our reviews break down the full fee picture for each platform. Always check the full fee schedule before opening an account.
An ISA (Individual Savings Account) is a UK tax wrapper that lets you invest or save up to £20,000 per year without paying tax on any gains or income. A Stocks and Shares ISA lets you hold stocks and ETFs tax-free. A Cash ISA is the savings account equivalent. For UK investors, using your ISA allowance every year is one of the most straightforward ways to improve long-term investment returns. Not all investment apps offer ISAs; our reviews make ISA availability a key criterion.
