Editor's note
The UK has roughly 59 agencies that lead with paid social as a primary service. They split into three buckets: boutique and single-platform specialists charging £400-1,500 a month plus ad spend, mid-market paid-social shops running fuller programmes at £1,500-3,500, and full-service or multi-platform agencies covering Meta, TikTok, LinkedIn, and YouTube at £3,500-5,000+ or 10-20% of media. Most charge a flat retainer, a percentage of ad spend, or a hybrid with a minimum monthly floor. Paid social moves fast. Most accounts can launch inside a week and show useful direction in two to four weeks, though LinkedIn typically takes longer because audiences are smaller and CPMs are higher. The bigger question in 2026 is creative throughput. Meta's Advantage+ and the Andromeda algorithm shift have made creative quality the main lever, not bid management. Agencies without in-house production usually cannot test fast enough to keep up. The other 2026 shift is commerce. TikTok Shop is now a meaningful UK channel (eMarketer projects £11.75B in UK social commerce sales this year), and paid social increasingly funnels into in-app checkout rather than out to a brand website. Below: the index, filtered down to whoever is actually doing the work.
Typical cost
10-20% of spend
or £400-5,000/mo retainer

Single-platform boutique £400-1,500 · Mid-market £1,500-3,500 · Full multi-platform £3,500-5,000+. Hybrid models pair a £750-1,500 base with 10-15% above an agreed threshold. LinkedIn B2B sits at the top of the range due to higher CPMs.

Realistic timeline
Days to launch
2-6 weeks to stable performance

1-5 days audit + tracking · 3-14 days creative production · 1-3 days launch · 7-21 days learning phase · 2-4 weeks meaningful read on Meta and TikTok, 3-6 weeks on LinkedIn.

Red flags
6 to watch
in any pitch
  • · No in-house creative production - paid social is creative-led, weak throughput means slow learning
  • · Percentage-of-spend pricing with no committed monthly creative quota or testing cadence
  • · Avoids discussing iOS privacy, signal loss, Conversions API, or modeled conversions
  • · Cannot explain platform attribution windows vs GA4 or CRM, or how they reconcile the gap
  • · No first-party data integration - no CAPI, no Customer Match, no offline conversion imports
  • · Refuses to give the brand admin access to its own Meta Business Manager, TikTok account, or LinkedIn Campaign Manager

5 questions our editors get most often, answered honestly. No agency-marketing speak.

Curated by humans

UK paid social retainers in 2026 split three ways. Single-platform boutiques (Meta-only, TikTok-only) run £400-1,500 a month plus ad spend. Mid-market performance shops typically charge £1,500-3,500. Full multi-platform agencies covering Meta, TikTok, LinkedIn, and YouTube charge £3,500-5,000+, often on a percentage-of-spend basis between 10% and 20%. LinkedIn B2B specialists sit at the upper end because CPMs are higher and audiences smaller, so workload stays high even on modest spend.
