How to earn interest on Bitcoin in United Kingdom
Verified 2026-06-03 · 2 primary regulators · 4 venues compared
Short answer
Earning interest on BTC in the UK in 2026 is structurally distinct: Bitcoin has NO native smart contracts + NO native staking — yield requires (1) CeFi BTC lending at FCA-registered UK venues (largely defunct post 2022-2023 BlockFi/Celsius/Genesis bankruptcy wave; minimal UK retail offerings remain), (2) wBTC on Ethereum/L2 via Aave/Compound for ~0.5-2% APY, (3) BTC L2 native lending (Sovryn on Rootstock, Stacks DeFi). 2024-2025 spot BTC ETN UK approvals (alongside the broader cTP regime) created a regulated investment-product pathway: BTC ETN in ISA/SIPP wrapper + cash-management yield is the safer UK retail alternative to CeFi BTC yield.

| Venue | Supply Apy | Min Amount | Withdrawal | Risk Profile |
|---|---|---|---|---|
| Aave v3 wBTC (Ethereum L1 + L2) | wBTC: 0.5-2% | Any | Instant if pool liquidity | Smart-contract + BitGo (wBTC issuer) counterparty risk; wBTC depeg risk |
| Compound v3 wBTC | wBTC: 0.5-2% + COMP rewards | Any | Instant if liquid | Smart-contract + BitGo counterparty |
| Sovryn (Rootstock BTC L2) | rBTC: 1-3% | rBTC required | Rootstock bridge | Sovryn + Rootstock bridge risk |
| BTC ETN in ISA/SIPP (UK brokerage) | ETN tracks BTC price; cash-management yield on remaining ISA/SIPP cash separately | Brokerage minimums | Standard brokerage | Regulated investment product; ISA/SIPP tax-shielded |
Regulatory framing — United Kingdom
BTC yield products are FCA-regulated when offered by FCA-registered firms. The 2022-2023 CeFi bankruptcy wave informed UK regulatory posture — no UK FCA-registered firm offers a high-yield BTC deposit product as of 2026-06-03. DeFi paths via wrapped BTC operate outside FCA registration. ETN-in-ISA/SIPP is the cleanest UK retail tax-shielded path. Wrapping BTC → wBTC = CGT disposal of BTC under HMRC (separate-asset). Yield income from any source = INCOME TAX UK marginal rate.
Primary regulators: FCA · HMRC
Common gotchas
- CeFi BTC yield largely defunct post-2022-2023 (BlockFi/Celsius/Genesis bankruptcies).
- BTC → wBTC IS a CGT disposal in UK (separate-asset).
- BTC ETN in ISA/SIPP is tax-shielded but ETN ≠ BTC.
- DeFi yield NOT 1099-DA-equivalent; UK self-tracked on SA108 + income tax on yield rewards.
- Yield income = INCOME TAX UK marginal rate (NOT CGT).
- Reward tokens (COMP, etc.) carry separate cost basis.
Step-by-step
- Decide: ETN-in-ISA/SIPP vs wrapped-BTC DeFi vs accept no yield. ETN is safer; DeFi is higher-yield + higher-risk.
- If DeFi: BTC → wBTC via BitGo or similar (CGT disposal). Track BTC disposal at GBP FMV.
- Connect MetaMask to Aave v3 or Compound v3. L2 for cheap gas.
- Supply wBTC + earn yield. Receive aWBTC or cWBTC receipt.
- Track yield for income tax. Receipt-token balance changes = income at FMV.
- Plan exit + BTC ↔ wBTC round-trip. Second CGT event on wBTC → BTC.
Tax summary
BTC yield income = INCOME TAX UK marginal rate. BTC → wBTC IS a CGT disposal. DeFi positions NOT broker-reported. BTC ETN in ISA/SIPP tax-shielded. See HMRC Cryptoassets Manual.
