Cyber disruption, misinformation, payments and scams
Use this when: Online services fail or alarming messages ask you to take urgent action.
Current official instructions for your area take priority. UK Ready is an independent information site, not a government service. This guide is written from the official sources listed below; it has not yet had a specialist review. Sources checked 13 October 2026.
ACTION SUMMARY
- 1Find the original source rather than relying on a screenshot.
- 2Check the date, affected place and whether it is a test or an actual instruction.
- 3Verify through the relevant official service where possible.
- 4Distinguish a confirmed event from a forecast, investigation or unverified report.
- 5Do not share the claim as fact if verification is missing.
In detail
Power and cyber incidents can interrupt banking, card terminals, booking systems, healthcare portals and communications. A failed card payment does not establish a national cyberattack. Check the service provider's official status and keep the household's immediate physical needs in view.
UK Ready recommends keeping important documents and contact details accessible offline and, where affordable, a modest amount of cash in useful denominations stored securely. Cash cannot guarantee an open shop or available supplies. Avoid withdrawing money in a panic or broadcasting what you have stored.
Before disruption: Secure key accounts using the current NCSC advice and your provider's recommended authentication. Keep a safe account-recovery method and offline copies of necessary contact details. Do not store account passwords in a public emergency plan or share authentication codes with someone claiming to coordinate emergency aid.
During an incident: Be cautious about messages requesting payment for evacuation, urgent supply delivery, an account unlock or a 'safe' replacement bank account. Use a known number, official app or a website address you entered independently. Do not let urgency bypass verification.
For suspicious messages, GOV.UK identifies report@phishing.gov.uk for emails and 7726 for texts. If money or account access has been lost, contact your bank or service provider through a trusted channel immediately and use current official reporting routes. UK Ready should not embed an outdated fraud-service name without checking it.
Checking an alarming claim
- Find the original source rather than relying on a screenshot.
- Check the date, affected place and whether it is a test or an actual instruction.
- Verify through the relevant official service where possible.
- Distinguish a confirmed event from a forecast, investigation or unverified report.
- Do not share the claim as fact if verification is missing.
Threat levels, attack predictions, casualty counts, contamination maps and restoration times must not be generated from this knowledge pack. Keep live updates in a separate, time-stamped system using verified sources, and clearly show when it is unavailable or stale.

Common questions
How much cash should every household keep?
There is no universal amount in this pack. A modest affordable reserve in useful denominations can help with some payment failures, but cannot guarantee shops or supplies.
Includes a UK Ready planning suggestion, not official guidance.
