Ad Costs & Platform Performance

Average CAC: £40 £120 for consumer apps (Meta). £200 £600 for B2B SaaS (LinkedIn). Google Search CPCs: £2.50 £5.50 for competitive B2B terms.. Platform quirks: LinkedIn performs extremely well for London B2B, UK professionals have high LinkedIn engagement vs US.

Legal & Compliance Differences

UK ASA (Advertising Standards Authority) applies: no misleading income claims, before/after physical transformation claims require documentation, alcohol advertising has strict rules. GDPR applies, consent-based remarketing only, 'legitimate interest' for B2B is narrower than US interpretation.

What Creative Works in This Market

London audiences respond poorly to American-style aggressive sales copy ('limited time ONLY!', 'don't miss out!'). British reserve means understated confidence outperforms high-energy urgency. Self-deprecating humour works well in London consumer advertising.

FluxNote for This Market

Create UK-specific video variants: British English spelling in captions, UK pricing (£ not $), UK compliance disclosures (FCA for FinTech, MHRA for health), and culturally appropriate tone. Do not simply use US creative, conversion rates drop 30-50% with American-coded content.
