Public Relations agencies.

Public Relations is the discipline of building and defending reputation: media relations, corporate narrative, crisis communications, ESG and sustainability storytelling, internal comms, and executive positioning. It overlaps with digital PR but the goal is trust and stakeholder credibility, not backlinks. Success in 2026 is measured against outcomes, not the volume of clippings.

Editor's note
Only 12 agencies on AgencyIndex lead with Public Relations as their primary service, and that needs explaining. Most pure-play PR consultancies list themselves as communications firms rather than marketing agencies, so they sit outside this directory by design. The 12 here are PR-led shops that also do meaningful digital, content, or social work, plus integrated marketing agencies with a credible reputation practice. The wider UK field is bigger; for PR that joins up with the rest of a brand's marketing, this is the right shortlist. Pricing splits three ways. Boutique consultancies run £3,000-7,500 a month, mid-market firms £7,500-15,000, and network or holding-group practices (Edelman, Weber Shandwick, FleishmanHillard, Hill+Knowlton, Brunswick) charge £15,000-50,000+ for enterprise work. Senior day rates sit between £150 and £650 per hour. The craft itself has changed. AMEC's Barcelona Principles 3.0 have pushed measurement away from AVE (Advertising Value Equivalent, now a procurement red flag) toward outcomes: trust, message take-up, share of conversation. ESG comms has shifted from rhetoric to evidence under regulator scrutiny. Crisis plans now include deepfake scenarios. AI is useful for monitoring and first drafts, but agencies leaning on it to churn press releases are easy to spot and easy to walk away from.
Typical cost
£5,000-30,000+/mo
retainer, with project and day-rate options

Boutique £3,000-7,500 · Mid-market £7,500-15,000 · Network/holding-group £15,000-50,000+. Single launch or campaign project £3,500-15,000. Senior consultant day rates £150-650/hour. UK market average sits around £5,000/month for independent agency retainers.

Realistic timeline
12-week onboarding
then always-on with quarterly campaign moments

Weeks 1-2 discovery, audit, stakeholder interviews · Weeks 3-4 strategy, messaging house, 90-day calendar · Weeks 4-5 media training and spokesperson prep · Weeks 5-6 crisis playbook and holding statements · Weeks 6-8 first proactive wave · Weeks 8-12 first campaign moment and measurement baseline. Then monthly always-on activity with one major campaign per quarter.

Red flags
6 to watch
in any pitch
  • · AVE (Advertising Value Equivalent) presented as a real measure of success - AMEC's Barcelona Principles 3.0 explicitly reject it
  • · Reporting that stops at impressions, reach, and a coverage roundup with no link to trust, sentiment, or business outcome
  • · No documented crisis protocol: no holding statements, no out-of-hours contact tree, no deepfake or synthetic-media scenario planning
  • · Generic 'great media relationships' claims with no named journalists, beats, or recent placements in the brand target outlets
  • · AI-generated press releases at scale - templated tone, bland quotes, hallucinations, no senior editorial sign-off
  • · Flexible retainers with vague monthly deliverables, no out-of-scope pricing, and quiet fee creep over the year
