Starting an Investigative Podcast: A UK Journalist's Guide

Why Podcasting Works for Investigations

Investigative journalism and podcasting are a natural fit. Where a newspaper article gives you 1,500 words to explain a complex scandal, a podcast series gives you hours. Listeners develop a relationship with the story and the reporter over multiple episodes, which builds trust and engagement in ways that text cannot match.

For UK journalists, the podcast format also offers practical advantages:

Editorial independence: You control the story, the pacing, and the editorial decisions without the constraints of a traditional newsroom
Low barrier to entry: You can produce a professional-quality podcast for under £500 in equipment
Growing audience: UK podcast listening has increased year on year, with investigative and true-crime formats consistently ranking among the most popular
Impact: Investigative podcasts in the UK have led to criminal investigations being reopened, public inquiries being launched, and significant policy changes

Essential Equipment

You do not need a professional studio to get started. Here is the core equipment for a quality investigative podcast:

Microphone: A USB condenser microphone such as the Rode NT-USB Mini (£80-100) or the Audio-Technica AT2020USB+ (£120-150) delivers broadcast-quality audio. For field recording, a Zoom H5 or H6 handheld recorder (£250-350) is the industry standard.
Headphones: Closed-back headphones for monitoring — the Audio-Technica ATH-M50x (£120) or the Sony MDR-7506 (£100) are both excellent choices.
Pop filter: A simple pop filter (£10-15) eliminates plosive sounds and immediately improves audio quality.
Recording space: You do not need a studio. A quiet room with soft furnishings (carpets, curtains, cushions) to absorb echo works well. Avoid rooms with hard surfaces and windows overlooking busy roads.

Budget starter kit: USB microphone (£80), pop filter (£10), headphones (£50), free editing software = under £150 total. You can upgrade as your audience grows.

Recording Techniques

Good audio is non-negotiable for investigative podcasting. Listeners will forgive imperfect production values, but they will not tolerate poor sound quality:

Always do a test recording before any interview. Check levels, listen for background noise, and adjust microphone position.
Record in WAV or high-bitrate MP3 (at least 192kbps). You can compress later for distribution, but you cannot recover quality lost at the recording stage.
For remote interviews, use a platform that records each participant's audio locally for higher quality — Riverside.fm, Zencastr, or SquadCast all offer this. Avoid recording from standard video call platforms where possible.
For field recordings, use a windshield on your microphone and position yourself away from traffic and air conditioning units. Record 30 seconds of “room tone” (ambient silence) at each location for editing purposes.
Always have a backup recording. Use your phone as a secondary recorder — the quality will not match your primary device, but it is better than losing an interview entirely.

Editing Software

You do not need expensive software to produce a professional podcast:

Audacity (free, open-source): Perfectly adequate for editing interviews, adding music, and basic noise reduction. The learning curve is gentle and there are thousands of tutorials available.
Reaper (£48 for a personal licence): More powerful than Audacity with a professional feature set. Excellent for multi-track editing and mixing.
Adobe Audition (part of Creative Cloud subscription): Industry-standard audio editing with advanced noise reduction, spectral editing, and seamless integration with Adobe Premiere.
Descript (from £20/month): Allows you to edit audio by editing a transcript — you delete words from the text and the audio edits automatically. Particularly useful for narrative podcasts with heavy editing.

Narrative Structure for Investigative Podcasts

Investigative podcasting is storytelling. The best investigative podcasts do not just present facts — they take the listener on a journey. Consider these structural approaches:

The unfolding investigation: Take the listener through your reporting process in real time. Share dead ends, breakthroughs, and surprises as you experienced them. This format builds suspense naturally.
Character-driven narrative: Centre the story around the people affected. Investigations are ultimately about human impact — let your subjects tell their own stories in their own voices.
Episode structure: Each episode should have its own narrative arc while advancing the overall story. End episodes on cliffhangers or unanswered questions that compel listeners to continue.
Series length: Most successful investigative podcasts run between six and ten episodes. This gives enough space for depth without losing the audience. Plan your series arc before recording.

Legal Considerations for UK Podcast Journalists

Podcasts are subject to the same legal framework as any other form of journalism in the UK. Key considerations include:

Defamation: Everything you say in a podcast is a publication. The same rules on defamation law apply — ensure you can substantiate every factual claim.
Contempt of court: If your investigation touches on active legal proceedings, the Contempt of Court Act 1981 applies. Seek legal advice before publishing episodes that reference ongoing cases.
Data protection: The UK GDPR journalism exemption applies, but you should still handle personal data responsibly and be able to demonstrate that your processing is in the public interest.
Recording consent: Under UK law, you can record a conversation you are party to without the other person's consent. However, best practice is to inform interviewees that they are being recorded and obtain their consent — this also avoids editorial challenges later.
Music and copyright: Do not use copyrighted music without a licence. Use royalty-free music libraries or commission original compositions.

Distribution and Growing Your Audience

Getting your podcast in front of listeners requires a distribution strategy:

Choose a hosting platform: Acast, Podbean, Buzzsprout, or Anchor (Spotify for Podcasters) will distribute your podcast to Apple Podcasts, Spotify, and other directories automatically.
Create a companion website or page: Publish show notes, source documents, and transcripts for each episode. This supports accessibility and SEO.
Promote on social media: Share audiograms (short audio clips with waveform visuals), quotes from interviews, and behind-the-scenes content. Tag relevant organisations and individuals.
Submit to podcast directories: Beyond Apple and Spotify, ensure your podcast is listed on Google Podcasts, Amazon Music, and Pocket Casts.
Cross-promote: Appear as a guest on other podcasts, write companion articles for publications, and engage with the podcasting community on social media.

Monetisation Options

Sustaining an investigative podcast financially is a genuine challenge. Options include:

Listener support: Platforms like Patreon or Ko-fi allow listeners to contribute directly. Offer bonus content (extended interviews, behind-the-scenes episodes) as rewards.
Grants and funding: Organisations such as the Bureau of Investigative Journalism, the Google News Initiative, and the Rory Peck Trust offer funding for independent journalism projects including podcasts.
Advertising and sponsorship: Once you have a consistent audience (typically 1,000+ downloads per episode), you can attract advertisers. Host-read adverts tend to perform best.
Commission by a publisher: Pitch your podcast concept to media organisations (BBC, Guardian, Telegraph, Times) who may commission and fund the production.
Live events: Successful investigative podcasts can generate income through live shows and speaking engagements at journalism festivals.
