Kraken Review
Established UK crypto exchange with strong security, competitive Kraken Pro fees, GBP Faster Payments support, and FCA registration as both a cryptoasset business and EMI.
Quick Verdict: Kraken for UK Users
Kraken is a solid, security-focused exchange with genuine UK credentials — GBP Faster Payments rails, FCA registration as both a cryptoasset business and an EMI, and strong account security tooling (Global Settings Lock, Master Key). Kraken Pro offers competitive maker/taker fees for active traders. The persistent drawbacks are well-documented: Instant Buy/Sell is expensive (fixed 1% fee plus spread), account holds and compliance-led restrictions generate the majority of negative sentiment, and support escalations can be slow. Best for experienced UK traders; use with caution if you rely on simple buy flows or need rapid human support.

Pros
- FCA Registered (Dual): Kraken holds FCA registration as a cryptoasset business under the Money Laundering Regulations and FCA authorisation as an Electronic Money Institution (EMI) — one of the stronger UK regulatory footprints among crypto exchanges.
- Kraken Pro Order-Book Trading: Full maker/taker fee schedule with tiered pricing starting at 0.25%/0.40% — competitive for active UK traders who use limit orders.
- GBP Faster Payments Support: Supports GBP deposits and withdrawals via Faster Payments (FPS), making it one of the most UK-banking-friendly exchanges. FPS deposit options include some fee-free methods; FPS withdrawals cost £1.95.
- Advanced Account Security Tooling: Global Settings Lock and Master Key features provide user-configurable controls to prevent account takeover — more sophisticated than most mainstream rivals.
- Proof of Reserves Programme: Regular Merkle-tree style Proof of Reserves reporting with self-verification tooling, plus ISO/IEC 27001:2022 certification and SOC 2 Type 1 examination.
- Broad Asset Selection: ~630 assets and 700+ markets listed in the UK, with GBP pairs available across major assets.
- UK Tax Reporting Support: Formal partnership with Koinly for UK-focused tax reporting, including in-app connection steps and transaction history exports.
- Staking / Opt-in Rewards: Flexible and bonded staking available with weekly rewards (rates vary by asset; UK eligibility restrictions apply for some reward types).
Cons
- Account Holds & Compliance Restrictions: The most repeated UK complaint — accounts or funds being placed on hold during AML/KYC reviews, often with limited explanation and slow resolution via support tickets.
- Instant Buy/Sell Cost Trap: UK users who do not use Kraken Pro pay a fixed 1% fee plus spread; the total effective cost is frequently higher than expected and not clearly surfaced at the point of purchase.
- FPS Withdrawal Delays: While Faster Payments is the default GBP rail, some UK users report withdrawals remaining 'pending' for longer than Faster Payments implies, particularly during high-volume periods.
- UK Retail Derivatives Restriction: UK retail users cannot access derivatives products; access is limited to those meeting professional client criteria.
- Staking Eligibility Confusion: Kraken's Opt-in Rewards messaging indicates UK restrictions for some reward types, while staking pages still promote the product — creating confusion about what UK residents can actually access.
- Bank-Side Friction: Some UK banks query or limit crypto transfers to/from Kraken, though this is a broader UK banking ecosystem issue rather than Kraken-specific.
- Support Quality Gap: Live chat resolves straightforward queries quickly, but compliance-led escalations (restrictions, closures) receive scripted responses and extended resolution timelines.
Who Should Use Kraken in the UK?
Best For
- •Active traders who will use Kraken Pro for competitive maker/taker fees rather than defaulting to Instant Buy/Sell
- •UK residents who want GBP Faster Payments in/out and value strong FCA regulatory credentials (MLR registration + EMI authorisation)
- •Security-conscious users who want advanced account protection tools like Global Settings Lock and Master Key
- •Experienced users comfortable with a platform that applies rigorous AML/KYC compliance checks
Not Best For
- •Users who rely on Instant Buy/Sell or recurring purchases and are sensitive to higher effective costs (fee + spread)
- •Anyone who needs fast human support escalation — compliance-led restrictions can take significant time to resolve
- •UK retail users seeking derivatives trading access (restricted for non-professional clients)
- •Users who want the widest possible altcoin/memecoin selection — Kraken's ~630 assets leaves some niche tokens unlisted

Kraken Fees - What UK Users Should Know
Kraken Pro (recommended): Tiered maker/taker starting at 0.25% maker / 0.40% taker, scaling down with volume. Instant Buy/Sell: Fixed 1% trading fee plus an additional spread; Kraken+ subscription can waive the fixed fee within limits but spreads still apply. GBP Withdrawals: Faster Payments withdrawals cost £1.95; SWIFT available as a slower alternative. Card/digital wallet purchases can trigger a 72-hour hold on funds. Users who default to Instant Buy/Sell or recurring buys without monitoring total cost (fee + spread + payment method) often find the effective cost significantly higher than expected.
Is Kraken Safe?
Kraken maintains a strong security posture with ISO/IEC 27001:2022 certification and SOC 2 Type 1 examination completion. Over 95% of user funds are held in cold storage. Advanced account protection tools include Global Settings Lock and a Master Key system — both designed to reduce account-takeover risk, and notably more sophisticated than most mainstream rivals. Two-factor authentication via TOTP is supported with no SMS recovery option, preventing SIM-swap attacks. Kraken runs an ongoing Proof of Reserves programme with Merkle-tree style self-verification tooling and regular reporting. In June 2024, Kraken publicly disclosed patching an isolated bug in its deposit/funding system; Kraken stated client assets were not impacted or vulnerable, and the issue was remediated quickly. A Bug Bounty Programme is also maintained. UK regulatory credentials include FCA registration as a cryptoasset business under the Money Laundering Regulations and FCA authorisation as an Electronic Money Institution (EMI).

About Kraken
Kraken's UK proposition in 2026 is broadly "serious exchange, serious controls": it offers Faster Payments (GBP) funding, a clear split between higher-cost Instant Buy/Sell and lower-cost Kraken Pro trading, and unusually deep account security features (Global Settings Lock and Master Key) compared with many mainstream rivals. User sentiment is mixed across consumer review surfaces. On Trustpilot, Kraken sits around the mid-range, while Apple App Store ratings for both Kraken and Kraken Pro apps are high (4.7 and 4.8 respectively), and Google Play ratings are also strong in aggregate (4.5 and 4.7). However, the negative reviews and Reddit support threads are remarkably consistent about where pain concentrates: account holds, "closed without explanation" experiences, and slow resolution when a case becomes compliance-heavy. Kraken is generally a good fit for UK users who want GBP in/out via Faster Payments, will use Kraken Pro to avoid Instant Buy/Sell spread and fixed fee structure, and are comfortable with a platform that errs on the side of over-compliance. If you want near-bank-like customer protection or are highly sensitive to the risk of temporary restrictions, this is a platform to use cautiously. Crypto assets are not FSCS protected.
