PR Agency One is an award-winning public relations consultancy based in Manchester and London, working across B2B and B2C communications.
Our proposition is simple – creative effectiveness. We believe PR should deliver bold ideas and measurable outcomes, not activity for activity’s sake. That means campaigns that earn attention, shape reputation and demonstrate commercial impact.
Media relations sits at the core of everything we do. But it is never delivered in isolation. Our work is informed by insight from SEO, digital performance, audience behaviour and, increasingly, AI-driven discovery. The result is PR that performs as well in national media and trade titles as it does across digital platforms, search environments and generative AI outputs.
We specialise in five sectors – finance, retail and FMCG, technology, built environment and healthcare – combining sector knowledge with strong editorial judgement and senior-led delivery.
Internationally, we operate through One Network, our delivery framework spanning more than 26 countries, allowing us to roll out consistent campaigns with genuine local relevance.
Measurement underpins our approach. Through OneEval, our proprietary evaluation suite, we track PR impact across brand, reputation and commercial performance – moving beyond coverage counts to show how PR contributes to visibility, demand and business outcomes. This also includes helping organisations understand how their brands are surfaced, interpreted and trusted by AI platforms.
We do not chase gimmicks or short-term noise. We build campaigns that stand up editorially, travel digitally and can be evidenced properly.
If you are looking for a PR agency that blends classic media expertise with modern, integrated delivery – and can prove what PR is doing for your business – PR Agency One is built for that brief.
