Clearcast

Clearcast is the UK's pre-broadcast advertising clearance organisation, responsible for reviewing and approving TV and radio commercials before transmission.

Also known as: advertising clearance broadcast clearance Clearcast clearance commercial approval UK

What is Clearcast?

Clearcast is the independent body that reviews and clears television and radio advertisements in the UK before they can be broadcast. Established in 1993, it operates under delegated authority from Ofcom, the UK's communications regulator, to ensure all broadcast commercials comply with relevant codes and regulations.

Why It Matters

For media buying and marketing agencies, Clearcast is essential because no TV or radio ad can legally air without Clearcast approval. This clearance process protects consumers, maintains broadcast standards, and prevents regulatory breaches. Failure to obtain clearance before booking airtime can result in lost media investment, delayed campaigns, and potential Ofcom sanctions.

What Clearcast Reviews

Clearcast examines advertisements against the BCAP Code (Broadcast Committee of Advertising Practice Code), which covers:

  • Misleading claims: Ensuring product benefits are substantiated
  • Children's protection: Restricting certain products and messaging
  • Harmful content: Excluding ads for alcohol, gambling, and other restricted categories
  • Social responsibility: Verifying compliance with ASA and BCAP guidelines
  • Technical standards: Confirming audio/visual production meets broadcast specifications

The Clearance Process

Agencies typically submit ads to Clearcast 5-10 working days before scheduled broadcast. The organisation reviews scripts, finished materials, or both depending on the stage of production. Clearcast may approve, request amendments, or reject submissions. Complex categories (financial services, health claims, gambling) may require extended review periods.

Key Differences from Other Bodies

Clearcast specifically handles pre-broadcast clearance. The Advertising Standards Authority (ASA) handles post-broadcast complaints. While related, these are distinct functions: Clearcast prevents non-compliant ads from airing; the ASA investigates complaints after broadcast.

Practical Implications for Agencies

When planning campaigns, agencies must: - Budget additional time for Clearcast review - Prepare detailed substantiation for claims - Understand category-specific restrictions - Coordinate with broadcasters (ITV, Channel 4, Sky, etc.) who work with Clearcast - Consider potential amendments in creative planning

Different broadcasters may have additional requirements beyond Clearcast standards, so coordination is essential.

Digital and Streaming Context

Traditionally, Clearcast applied to linear broadcast (TV and radio). As media fragmentation continues, agencies should note that online video advertising has different regulatory pathways, though advertiser responsibility remains high.

Frequently Asked Questions

Do all UK TV ads need Clearcast approval?
Yes, all broadcast commercials on UK television and radio channels require Clearcast clearance before transmission. This is a legal requirement under delegated Ofcom authority. Online-only video content has different regulatory pathways.
How long does Clearcast approval take?
Standard reviews typically take 5-10 working days. Complex submissions (financial services, health claims, gambling) may take 15+ working days. Urgent requests can sometimes be expedited, but this depends on complexity and broadcaster deadlines.
What happens if an ad is rejected by Clearcast?
If rejected, Clearcast provides specific reasons and guidance for amendments. Agencies can resubmit revised versions. If the core concept is non-compliant, substantial creative changes may be needed. Rejection delays campaigns, so early submission is crucial.
Who pays for Clearcast clearance?
The advertiser or their agency typically bears Clearcast fees, which vary by submission type and complexity. Costs are usually modest but should be factored into campaign budgets alongside media buying costs.
