Storing cryptoassets safely in the UK — custody guide
Quick answer: You can leave crypto on the exchange where you bought it (easy but risky if the company fails), or move it to a wallet you control (more secure but you must not lose the password). Never share your recovery phrase with anyone — not even 'support staff'.
When you buy crypto, it lives in an app or website — not in your pocket. This guide explains your options in plain English, including the biggest mistake beginners make: losing their recovery phrase.
Exchange custody vs self-custody
Leaving tokens on an exchange is convenient but concentrates risk — hacks, insolvency and withdrawal freezes have affected UK and overseas users. Self-custody via a hardware or software wallet gives you control but full responsibility for key security.
Hot and cold wallets
Hot wallets are connected to the internet (mobile apps, browser extensions). Cold storage keeps keys offline (hardware wallets, paper backups). For significant holdings, cold storage with a tested backup process is standard good practice.
Seed phrases and backups
Your recovery phrase is the master key. Store copies securely offline — not in email, cloud notes or photos. Consider split backups and informing a trusted person how to access them if you die, without publishing the phrase in your will.
Digital assets and UK property law
The Property (Digital Assets etc) Act 2025 clarifies that certain digital assets, including crypto, can be treated as property capable of being owned and transferred under the law of England and Wales. This supports including digital assets in estate planning, though Scottish and Northern Irish law may differ — take legal advice for cross-jurisdiction estates.
Inheritance planning
Document what you hold, where, and how an executor can access assets without compromising security. Use a letter of wishes or secure vault rather than embedding secrets in the will. Executors may need specialist help to value holdings for probate and IHT.
