Sources and last reviewed dates
Our approach
Every safety claim on this site is traceable to a named source: a regulator, an industry body, a provider's published documentation, or a charity's guidance. We do not rely on anonymous tips, social media posts, or unverifiable claims.
Where something is uncertain or contested, we say so. We do not dress up guesses as confidence.
Primary sources
- Ofcom, the UK communications regulator. Source for rules on power-cut resilience, emergency calling obligations, and provider conduct.
- Openreach, the network operator for most UK providers. Source for network timeline, stop-sell areas, and technical details of the switch-off.
- BT, Sky, TalkTalk, Plusnet, EE, Vodafone, individual provider documentation for how each handles the migration.
- Telecare Services Association (TSA), the industry body for telecare. Source for guidance on telecare migration.
- Fire Industry Association (FIA), source for fire alarm signalling requirements.
- National Security Inspectorate (NSI), source for security alarm monitoring standards.
- Action Fraud, the national reporting centre for fraud and cyber crime. Source for scam reporting guidance.
- Age UK, Citizens Advice, charities that have published guidance for older people affected by the switch.
Last reviewed dates
Every page on this site that contains safety-related information shows a "last reviewed" date. This is the date we last checked the content against current sources. It does not mean nothing has changed since that date. It means we checked on that date and the information was accurate at that time.
We aim to review all pages at least every three months. If a significant change happens (for example, a new Ofcom ruling or a deadline change), we update the affected pages and mark the new review date.
