You can earn interest on crypto in the UK through staking, lending and DeFi yield — but the headline rates hide real risks, no FSCS protection, and an income tax bill. Here's how each method works and what to watch for.
Important Risk Warning
This is not financial advice. Cryptocurrency investments are highly volatile. The value of your investment can go down as well as up, and you could lose all the money you invest. Don't invest unless you're prepared to lose all the money you put in.
You can earn interest on crypto in the UK three main ways: staking proof-of-stake coins, lending through a platform, or providing liquidity in DeFi. Realistic yields in 2026 range from low single digits for staking to higher — and riskier — returns in DeFi. But before the rates tempt you, two facts: there's no FSCS protection on any of it, and HMRC taxes the rewards as income. "Crypto interest" is not a savings account.
I want to be honest about that, because the marketing makes it sound like one. The 2022 collapses of Celsius and BlockFi wiped out ordinary savers who thought they'd found a high-yield deposit. The mechanics matter.
Three broad routes, each with a different risk profile:
Our DeFi tax guide and staking economy piece go deeper on the last two.
Staking is the most accessible route. You commit a proof-of-stake coin — say Ethereum — and in return for helping validate transactions you receive periodic rewards, typically a few percent a year. You can stake through an exchange (the easy way) or run your own validator (the technical way, with higher rewards and higher responsibility).
The catch is lock-up and price risk. Staked coins are often tied up for a period, and a 4% yield means nothing if the underlying coin drops 30%. You're earning more of an asset whose price you don't control.
Ignore anyone promising fixed double-digit returns "guaranteed" — that's the language that preceded every blow-up. Realistic, sustainable figures look more like:
| Method | Typical yield range | Main risk |
|---|---|---|
| Staking (ETH, SOL, ADA) | ~2–7% | Lock-up, token price, slashing |
| Centralised lending | ~3–10% | Platform insolvency, no FSCS |
| DeFi liquidity pools | Variable, can be higher | Impermanent loss, smart-contract bugs, scams |
Higher advertised rates almost always mean higher risk somewhere — counterparty, smart contract, or a token that's about to crater. There's no free yield.
Start with the big one: no FSCS protection. If a lending platform goes insolvent, there's no UK compensation scheme — you're an unsecured creditor, as Celsius depositors learned. Counterparty risk is real and it has bankrupted savers.
Then smart-contract risk in DeFi — code can be exploited, and a hacked protocol can drain a pool in minutes; our write-up of the KelpDAO bridge exploit is a recent example. There's impermanent loss in liquidity pools, where the value of your deposited pair can fall below simply holding. And there's plain fraud — "high-yield crypto accounts" are a classic scam wrapper. The FCA's promotion rules exist precisely because of this.
My take: treat crypto yield as putting capital at risk for a return, never as earning interest in a safe place. The word "interest" does a lot of misleading work here.
Yes. HMRC generally treats staking and lending rewards as income, taxable at your usual income tax rate based on the sterling value when you receive them. Then, when you later sell those reward tokens, any change in value since receipt is a capital gains matter — so a single reward can be taxed twice, in two different ways.
Keep a record of each reward: date, tokens received, sterling value. That's both your income figure and your future cost basis. Our crypto income tax guide breaks down the rules, and tax software makes the bookkeeping survivable.
Is earning interest on crypto safe in the UK? No method is "safe" in the savings-account sense. There's no FSCS protection, and risks range from platform insolvency to smart-contract exploits. Staking is generally lower-risk than lending or DeFi, but the underlying coin can still fall in value.
How much can I realistically earn staking crypto? Typically around 2–7% a year depending on the coin, paid in more of that token. Remember the yield is in crypto, so the sterling value depends on the coin's price, which can swing far more than the yield.
Do I pay tax on staking rewards in the UK? Yes. HMRC usually treats staking and lending rewards as income at the sterling value when received, then capital gains tax may apply on any growth when you later dispose of the tokens.
What happened to Celsius and BlockFi? Both were crypto lending platforms that collapsed in 2022, freezing and in many cases losing customer deposits. They're the cautionary tale behind why "no FSCS protection" is not a footnote.
Is DeFi yield farming worth the risk? That depends entirely on your risk tolerance and technical understanding. The potential returns are higher, but so are the ways to lose — impermanent loss, exploits and scams. It's not for beginners or for money you can't afford to lose.
Earning yield on crypto is real and, done carefully with reputable methods, can be a sensible part of holding assets you already own. But strip away the word "interest" — there's no safety net, the rewards are taxed as income, and chasing the highest rate is how people get burned. Stake what you understand, never deposit more than you can lose, and keep records for HMRC. This is general information, not financial advice.
