How to Record Business Calls in the UK (3 Best Methods)

Whether it's a customer confirming a quote, a supplier agreeing on a delivery date, or a team member taking instructions over the phone — business calls contain information you can't afford to lose.

Recording those calls gives you a safety net. Disputes get resolved faster. Training becomes easier. And nothing falls through the cracks because someone misremembered what was said.

But in the UK, there are specific laws that govern when and how you can record calls. Get it wrong and you're looking at GDPR fines. Get it right and you've got a powerful tool for protecting and growing your business.

This guide covers the law, the best methods, and how to stay compliant.

UK law on recording phone calls

The legal framework for call recording in the UK rests on two key pieces of legislation:

RIPA 2000 — one-party consent

The Regulation of Investigatory Powers Act 2000 (RIPA) allows you to record a phone call you're a party to, for your own personal use, without telling the other person. This is known as one-party consent — you only need your own permission to record.

This means: if you're on the call, you can record it. Legally.

Business recording — the Telecommunications Regulations 2000

For businesses, the Telecommunications (Lawful Business Practice) (Interception of Communications) Regulations 2000 goes further. It allows businesses to record calls without consent for specific legitimate purposes:

• Quality assurance and training — monitoring staff performance and coaching
• Regulatory compliance — meeting obligations in finance, insurance, or healthcare
• Establishing facts — keeping a record of what was agreed (quotes, orders, instructions)
• Preventing crime — detecting fraud or unauthorised use of your phone system

If your reason for recording falls outside these categories — for example, market research or selling data — you must get explicit consent from the caller.

UK GDPR — recordings are personal data

Here's the part most small businesses miss: a recorded phone call is personal data under UK GDPR. That means you need to:

• Have a lawful basis for processing the recording (legitimate interest usually covers business calls)
• Inform callers that you're recording — an automated message at the start of the call is standard
• Store recordings securely — encrypted, access-controlled, not sitting in a shared Google Drive
• Have a data retention policy — keep recordings only as long as needed, then delete them
• Allow callers to request access to or deletion of their recordings under data subject rights

Failing to comply with UK GDPR can result in fines of up to £17.5 million or 4% of annual global turnover.

Comparing the 3 best methods

Each method suits different needs. Here's when to use each one.

Method 1: Business phone system with built-in recording (recommended)

Best for: Businesses that want recording handled automatically, with compliance built in.

The cleanest way to record business calls is to use a phone system that has recording built in. No extra apps, no merging calls, no remembering to press a button — every call is captured automatically.

With Line's Business plan, call recording is a native feature. When enabled, calls are recorded from the moment they're answered, stored securely, and accessible from your dashboard. Your team can play back, search, and manage recordings from one place.

Because Line is your business phone system — not a bolt-on app — the compliance workflow is built in:

• Automatic caller notification — callers hear a brief recording notice before the call connects
• Secure cloud storage — recordings are encrypted and access-controlled
• Retention controls — set how long recordings are kept before automatic deletion
• Team permissions — control who can access recordings

This matters because it means you don't have to think about compliance for every call. The system handles it.

What it costs: Line's Business plan is £19/month and includes call recording alongside your business number, team inbox, business hours, and voicemail transcription. There's no per-minute recording fee and no storage surcharge.

Method 2: Dedicated call recording app (TapeACall)

Best for: People who want to record calls on their existing personal or business phone without changing their phone system.

TapeACall is the most established call recording app for iPhone and Android. It works by using your phone's conference call (three-way merge) feature — when you want to record, the app dials into the call as a silent third party and captures the audio.

How it works:

1. Open TapeACall before or during a call
2. Tap the record button — the app dials a recording line
3. Merge the calls using your phone's conference call feature
4. The recording is saved to TapeACall's cloud and available in the app

Pros:

• Works on any iPhone or Android phone
• Records both incoming and outgoing calls
• AI transcription included on paid plans
• Recordings stored in the cloud with sharing options (email, Dropbox, Google Drive)

Cons:

• You have to remember to start recording for every call — nothing is automatic
• The conference-call method adds friction and can occasionally fail
• No caller notification — you're responsible for telling the other person
• No compliance tools, retention policies, or team access
• Doesn't work if your carrier blocks conference calls

What it costs: TapeACall Pro costs approximately £7/month or £60/year. There's no free tier for call recording — only a limited trial.

Method 3: AI transcription tool (Otter.ai)

Best for: People who primarily need a written transcript of calls rather than an audio recording — especially for meetings, interviews, and consultations.

Otter.ai takes a different approach. Rather than tapping into your phone line, it uses your device's microphone to listen to and transcribe conversations in real time. You place the call on speakerphone (or use a headset with microphone passthrough) and Otter captures the audio and produces a searchable, editable transcript.

How it works:

1. Open Otter.ai on your phone or laptop
2. Start a new recording
3. Place your call on speakerphone or use a connected headset
4. Otter records and transcribes the conversation in real time
5. When the call ends, stop the recording — the transcript is saved automatically

Pros:

• Real-time transcription with speaker identification
• Searchable transcripts — find specific moments by keyword
• AI-generated summaries and action items
• Free tier available (300 minutes/month)
• Works for phone calls, in-person meetings, and video calls

Cons:

• Speakerphone required for phone calls (not always practical on-site or in public)
• Audio quality depends on your environment — background noise is a problem
• Transcription accuracy drops with strong accents, poor signal, or multiple speakers
• No direct integration with your phone's call system
• Free tier is limited to 30 minutes per conversation

What it costs: Otter.ai has a free plan (300 minutes/month, 30 minutes per conversation). The Pro plan is approximately £14/month (billed annually) and gives you 1,200 minutes with longer conversations and advanced features.

Which method should you choose?

The right method depends on your situation:

Choose a business phone system (Line) if you want call recording to just work — automatically, compliantly, with no extra steps. This is the best fit if you're recording calls regularly, have a team, or work in an industry where compliance matters. You also get a dedicated business number and team features, so you're not paying for two separate tools.

Choose a recording app (TapeACall) if you already have a phone system you're happy with and just want to add recording to specific calls. It's the most affordable option if you only need to record occasionally — but the manual process and lack of compliance features make it less suited for regular use.

Choose an AI transcription tool (Otter.ai) if what you really need is a written record of conversations rather than audio playback. It's excellent for meetings, interviews, and consultations where you need to reference what was said — but the speakerphone requirement makes it impractical for everyday business calls.

Staying compliant: a quick checklist

Whichever method you choose, follow these steps to stay on the right side of UK law:

• Tell callers you're recording — an automated message or verbal notice at the start of the call
• Record for a legitimate purpose — training, quality, compliance, or establishing facts
• Store recordings securely — encrypted storage with access controls, not an open folder
• Set a retention period — decide how long you'll keep recordings (6-12 months is typical) and delete them after
• Document your policy — write a brief call recording policy that covers why you record, how long you keep recordings, and how callers can request access or deletion
• Register with the ICO — if you're processing personal data (which recordings are), make sure you're registered with the Information Commissioner's Office

Next steps

Recording your business calls protects you from disputes, helps you train your team, and means nothing important gets lost because someone forgot what was said on the phone.

If you want the simplest, most compliant approach, sign up for Line and enable call recording on the Business plan. You'll get a UK business number, automatic recording, and compliance tools — all in one place, set up in under 3 minutes.
