CPM (Cost Per Mille) in United Kingdom

January 2025 - January 2026

Insights

Detailed observation of presented data

Introduction

Great Britain’s Facebook Ads CPMs tracked below the global benchmark for most of 2025, then finished the year with a striking surge. The market opened soft, lifted through mid-year, dipped sharply in October, and then spiked to a December high that eclipsed any global month. Volatility was a defining feature: swings were larger and more frequent than the global pattern, with standout moments in July, October, and December shaping the story.

This analysis is based on $3B worth of advertising data from our dataset, which provides strong directional benchmarks. This analysis explores ad performance trends for all industries in Great Britain compared to the global benchmark.

The story in the data

  • Starting point vs. finish: Great Britain’s median CPM rose from £13.64 in January to £34.43 in December, a +152% climb across the year.
  • Range and average: The market averaged £18.89, ranging from a low of £13.64 (January) to a high of £34.43 (December).
  • Key movements: February rebounded (+24% MoM), April firmed (+11%), and June advanced (+15%). July marked a step-change to £22.23, followed by an August correction (−23%) and a September recovery (+16%). October dropped to £14.24, the year’s second-lowest point, before a two-month surge: +51% in November and +60% in December.
  • Volatility: Average month-to-month absolute movement was £4.33, roughly 3.7x the global benchmark’s £1.18, underscoring a choppier price environment in Great Britain.

Seasonal and monthly dynamics

The rhythm was a gradual build punctuated by sharp inflections. Q1 was the softest quarter (avg £15.30), Q2 firmed (avg £17.11), and Q3 advanced further (avg £19.76) despite an August dip. Q4 was the most expensive (avg £23.40), shaped by an unusually weak October and an outsized December. Globally, Q4 is typically the priciest stretch, with November often peaking; Great Britain followed the seasonal direction but with more dramatic amplitude—especially an exceptional December that broke the annual range.

Country vs. Global

  • Overall level: Great Britain’s 2025 CPM averaged £18.89 versus the global £20.19, about 6% below market.
  • Momentum: The global index rose a steadier +26% from January to December, peaking in November (£25.26) before easing. Great Britain rose +152% across the same span, with larger swings and a late-year overshoot.
  • Monthly gap: Great Britain trailed global levels most months—down 23% in January, 20% in March and May, and a wide 35% in October. The gap narrowed to near parity in September. Above-market moments appeared in July (+14%) and decisively in December (+54%).
  • Standout comparison: Great Britain’s December CPM (£34.43) not only set the local annual high; it also exceeded the global annual peak (November, £25.26) by roughly 36%.

Closing

This CPM analysis highlights how Facebook Ads benchmarks for all industries in Great Britain diverged from global patterns—softer through most of the year, then sharply above market in December. Understanding country-specific ad costs and CPM trends in Great Britain helps advertisers contextualize performance against the global benchmark and anticipate how local dynamics can reshape year-end pricing pressure.

Understanding the Data

Insights & analysis of Facebook advertising costs

Cost Per Mille (CPM) is the cost advertisers pay for 1,000 impressions of their Facebook ad. Different industries see varying ad costs due to market competition, user demographics, and conversion value. For campaigns targeting United Kingdom, advertisers experience moderate to high costs with strong performance in urban areas. Different campaign objectives lead to varying costs based on how Facebook optimizes for your specific goals. The data shown represents median values across multiple campaigns, and individual results may vary based on ad quality, audience targeting, and campaign optimization.

Why we use median instead of average

We use the median CTR because the underlying distribution of click-through rates is highly skewed, with a small share of campaigns achieving extremely high CTRs. These outliers can inflate a simple average, making it less representative of what most advertisers actually experience. By using the median—which sits at the midpoint of all campaigns—we provide a more rigorous and realistic benchmark that reflects the true underlying data model and helps you set attainable performance expectations.

Key Factors Affecting Facebook Ad Costs

  • Competition within your selected industry and audience demographics
  • Ad quality and relevance score – higher quality ads can lower costs
  • Campaign objective and bid strategy
  • Timing and seasonality – costs often increase during holiday periods
  • Ad placement (News Feed, Instagram, Audience Network, etc.)

Note: This data represents industry median values and benchmarks. Your actual costs may vary based on specific targeting, ad creative quality, and campaign optimization.

Potential Advertising Impact

CPM and CPC might increase around early May and late August bank holidays as people engage in leisure travel or retail browsing. During Black Friday/Cyber Monday, retail CPMs could spike sharply in fashion, electronics, and online shopping. Late December typically sees peak CPMs, with e‑commerce budgets needing early ramp-up.

What affects CPM rates on Facebook Ads?

CPMs are heavily influenced by competition, seasonality (e.g., Q4 costs more), audience size, and ad quality. Smaller audiences and lower relevance scores often lead to higher CPMs.

Why does my CPM vary so much between campaigns?

Different campaign objectives, bidding strategies, and even time of day can change your CPM. For example, conversion campaigns usually have higher CPMs than traffic ones. Also, broad targeting tends to drive lower CPMs.

What's a competitive CPM for 2025?

In most industries, CPMs range from $5 to $18 depending on the region and objective. Retail and e-comm campaigns often sit at the higher end. Our live data above shows a breakdown by country and industry.

Does audience size or targeting affect CPM more?

Both matter, but audience quality (intent + match with your offer) usually has more impact than pure size. However, extremely tight audiences often lead to expensive CPMs due to limited delivery opportunities.

Should I worry more about CPM or CPC?

Depends on your goal. For awareness, CPM is more relevant. For performance campaigns, CPC and CPA matter more. But all are connected—inefficient CPMs can inflate your entire funnel.
