Ever finished a call and wished you could play it back? Recording your business calls is more common than it used to be: handy for training new staff, and for keeping a clear record of what was agreed. The trick is doing it properly, and staying on the right side of the law. Here's how.

The legal bits worth knowing first

Before you hit record, it's worth knowing where you stand. The rules for recording calls differ from country to country. In the UK, here's the gist
 

  • A business can legally record its own calls under the Telecommunications (Lawful Business Practice) Regulations 2000, for things like training, quality, record-keeping or sorting out disputes.
  • You don't always need consent, but you do need a lawful basis under UK GDPR (usually legitimate interests), and you must make reasonable efforts to tell callers that a recording may take place.
  • You can only use a recording for the purpose you told people about. Anything beyond that needs their say-so.
  • Callers can ask for a copy of their own recording (a subject access request), and you've got a month to respond.
  • You have to be open about what happens to the data, and keep recordings secure so only authorised people can get to them.
  • There's no single legal limit on how long you can keep a recording—set a sensible retention period and delete it once it's served its purpose. (Some regulated sectors, like finance, have stricter rules.)


* Always check which rules apply to your own situation. Rinkel can't be held responsible for any breach of the rules.

    How to record a call legally

    1. Tell the caller. Let the other person know the call's being recorded. A quick line just before, or right at the start, does the job.
    2. Use a tool you can trust. Pick an app or service that meets data protection and privacy rules.
    3. Store recordings safely. Keep them somewhere secure, with access limited to the people who actually need it.

    Examples:

    • In a business call: "This call may be recorded for training purposes."
    • In an interview: "Would you mind if I record our chat, just so I don't miss any of your feedback?"

    Your recording options

    Most mobiles come with some way to record calls built in, or let you install an app that handles it. Whatever you go for, make sure it keeps that data private.
