Creative agencies in Cardiff.

An above-the-line campaign from brief to launch runs eight to sixteen weeks in a typical UK schedule: one week brief, one to two weeks strategy, two to three weeks concept development and client selection, one to two weeks script and design, then pre-production, production, post, adaptation, and trafficking. Complex multi-market or talent-led work runs twelve to twenty weeks or longer. Always-on social and digital creative runs one to four weeks per asset burst once template systems exist.

A branding agency builds the system upstream: positioning, identity, voice, guidelines, and the rules that govern how a brand shows up. A creative agency takes that system and produces the campaign idea and executions that go live on paid channels: TV, video, OOH, radio, social film, and the rollout toolkit. The work is sequential. Brand is set first, the creative agency picks up the deliverables and turns them into a campaign that runs in the market.

Creative agencies produce campaign ideas: a platform thought, a hero film, key visuals, scripts, and the executions that drive paid awareness. Content marketing agencies run the always-on layer underneath: articles, video, podcasts, and SEO-led pieces that build authority and feed demand over months. The two work in sequence. A campaign creates the spike, content marketing holds the line between campaigns. Some agencies do both, but the disciplines have different rhythms, fee structures, and measurement models.

Generative AI has industrialised production. Moodboards, variants, scripts, voiceovers, and adaptation packs are faster and cheaper, so the production layer no longer carries the fee it used to. The premium has moved upstream to insight and the platform idea, and downstream to performance creative built on live data. The creative-media split is dissolving as a result. Credible UK shops should have a clear AI usage policy covering what gets generated, how it is reviewed, and where rights sit.
