What to do if…
police ask to take, unlock, or search your phone or another electronic device

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy UK guide

Short answer

Stay calm and ask whether the police are taking the device under a legal power or asking for your voluntary agreement. Before consenting, unlocking it, providing a passcode, or answering questions about its contents, ask to speak privately with a solicitor.

Do not do these things

  • Do not physically resist an officer taking the device.
  • Do not delete, alter, conceal, reset, damage, encrypt, or remotely wipe anything.
  • Do not ask someone else to change or delete connected accounts or data.
  • Do not assume that a request means you are legally required to agree.
  • Do not provide a passcode or use facial or fingerprint unlocking simply because you feel pressured or rushed.
  • Do not sign a consent or agreement form that you do not understand.
  • Do not discuss what is stored on the device before obtaining legal advice.
  • Do not ignore a formal written notice requiring access to protected information.

What to do now

  1. Ask clearly: “Are you taking this device under a legal power, or are you asking for my voluntary agreement?”
  2. Ask what legal power, warrant, written notice, or consent process the police are relying on. Do not argue about the answer at the scene.
  3. Say: “I want legal advice before I consent, unlock the device, provide a passcode, or answer questions about its contents.”
  4. If you are detained, at a police station, or being interviewed as a suspect, ask to speak privately with a solicitor. Free police-station legal advice is available in many circumstances, although the arrangements differ across the UK.
  5. If officers take the device, do not obstruct them. Ask for a written record, property receipt, or other paperwork identifying the device and the stated basis for taking it.
  6. If access is described as voluntary, ask what data is sought, why it is relevant, which applications or accounts may be examined, what period is involved, and whether a narrower way of providing the relevant material is available. Obtain legal advice before deciding.
  7. If you receive a formal notice requiring disclosure of protected information, an encryption key, or information needed to access data, keep the notice and contact a criminal defence solicitor promptly. Knowingly failing to comply with a valid notice can be a criminal offence.
  8. If the device belongs to an employer, relative, or another organisation, tell the police who owns it. Do not contact the owner to alter its contents.
  9. Write down the officers’ names or numbers, the police force, what was requested, what you said, whether you agreed to anything, what paperwork you received, and when the device was taken. Keep the notes somewhere other than the device.
  10. Tell the officer and your solicitor if the device contains something you urgently need, such as medication information, accessibility tools, essential contact details, travel documents, or authentication access. Ask whether a practical arrangement can be made without changing the stored data.

What can wait

You do not need to decide immediately whether the police acted lawfully, make a complaint, replace the device, change every password, contact everyone named in it, or reconstruct all its contents. First establish whether access is compulsory or voluntary, obtain any available paperwork, record what happened, and seek legal advice.

Important reassurance

You can remain calm and cooperative without volunteering consent, a passcode, or detailed information. Police powers depend on the circumstances and on whether you are in England and Wales, Scotland, or Northern Ireland, so asking for the legal basis and obtaining advice is a reasonable immediate step.

Scope note

This guide covers immediate first steps when UK police ask to take, unlock, or search an electronic device. Questions about seizure, examination, copied data, consent, formal notices, retention, return of property, complaints, or court proceedings may require advice from a solicitor familiar with the relevant part of the UK.

Important note

This is general information, not legal advice. Police powers and procedures differ between England and Wales, Scotland, and Northern Ireland, and the correct response depends on your status, the investigation, the location, and any warrant, statutory power, consent process, or formal notice involved.
