Paid Social Advertising Costs UK 2026: A Platform-by-Platform Guide
Written by: Simon
UK social media advertising spend hit £11.5 billion in 2025, a 21% increase on the previous year according to IAB UK’s Digital Adspend study. That makes paid social the fastest-growing major channel in the UK digital market, now accounting for 28% of all digital ad spend.
But growth in spend means growth in cost. CPMs are climbing across every major platform, and advertisers planning budgets for the rest of 2026 need current numbers, not figures from two years ago. This guide covers what UK businesses are actually paying on Meta, LinkedIn, TikTok, YouTube, Pinterest and Snapchat right now, with benchmarks, context, and practical guidance on where your budget works hardest.
The UK paid social market in 2026
Social media advertising now represents the single largest category within UK digital spend. The £11.5 billion figure from IAB UK’s 2025 report reflects a market that has more than doubled since 2020, and forecasts suggest a further 10% growth in 2026.
Within that total, video now accounts for 59% of social investment. Short-form video on TikTok and Reels, longer formats on YouTube, and in-feed video across Meta and LinkedIn are all pulling budget away from static display. For advertisers, this shift matters because video inventory tends to carry higher CPMs than static placements.
Most industry forecasts point to a 5% to 10% increase in paid social costs across platforms this year. Three factors are driving that:
- More advertisers competing for the same inventory. UK businesses spent more on paid social in 2025 than ever before, and that competition pushes auction prices up.
- Platform automation is consolidating targeting. Meta’s Advantage+ and similar tools mean more advertisers are bidding on overlapping audiences, which increases CPMs in high-demand segments.
- Format shifts toward video. Video placements cost more to serve and more to win in auction. As platforms prioritise video, average costs rise.
None of this means paid social is becoming less effective. But it does mean that knowing your cost benchmarks, by platform and by objective, is more important than it was twelve months ago.
Platform-by-platform cost comparison
Before looking at each platform in detail, here is a summary of what UK advertisers can expect to pay across the seven major paid social platforms in 2026.
| Platform | Avg CPC | Avg CPM | Best for |
|---|---|---|---|
| £0.26-£0.50 | £8-£16 | Lead gen, ecommerce, broad reach | |
| £0.30-£2.00 | £5-£12 | Brand awareness, visual products | |
| £2.00-£6.25 | £20-£35 | B2B lead gen, senior decision-makers | |
| TikTok | £0.30-£1.20 | £4-£8 | Awareness, younger audiences |
| YouTube | £0.04-£0.25 (CPV) | £3-£12 | Video reach, consideration |
| £0.50-£1.00 | £2-£5 | Retail, home, fashion discovery | |
| Snapchat | £0.70-£1.00 | £3-£8 | 16-30 demographic, AR formats |
These are indicative ranges based on published benchmarks and industry data. Actual costs vary by targeting, creative quality, objective, and seasonality. The sections below explain what drives those differences on each platform.
Meta: Facebook and Instagram costs
Meta remains the default starting point for most UK paid social campaigns, and for good reason. The platform handles the widest range of objectives, from brand awareness through to direct-response ecommerce, and its auction system is the most mature in the market.
Facebook cost benchmarks
Average UK Facebook CPCs in 2026 sit between £0.26 and £0.50 for most campaign types, based on SuperAds’ UK benchmark data. CPMs range from around £8 to £16, though these figures move significantly by quarter. In Q4 2025, UK Facebook CPMs spiked above £25 as holiday competition intensified, before settling back to around £10 to £12 in January 2026.
For lead generation, Facebook remains one of the most cost-effective options. The average cost per lead sits at roughly £5.83 for UK campaigns using Lead Ads, though this varies by industry. Finance and insurance leads cost more; retail and entertainment cost less.
Instagram cost benchmarks
Instagram CPCs tend to run slightly higher than Facebook, typically £0.30 to £2.00 depending on placement and objective. Reels and Stories placements often deliver lower CPMs than feed placements, but the click-through rate on Stories is also lower, so the cost per outcome can end up similar.
Instagram’s strength is conversion efficiency. According to Digital Applied’s 2026 platform comparison, Instagram delivered an average conversion rate of 1.85% across campaigns, the highest of any major social platform.
The Advantage+ factor
Meta’s Advantage+ automated campaigns are changing how costs behave. According to AdAmigo’s 2026 benchmark analysis, Advantage+ campaigns can reduce cost per result by up to 44% compared to manual campaign setups, with an average 22% improvement in ROAS. That efficiency comes with less control over audience selection and placement, though. For brands that need to target specific segments or exclude certain audiences, a hybrid approach tends to work better: Advantage+ for remarketing and broad prospecting, manual campaigns for tighter targeting. We covered this in more detail in our post on Meta’s campaign automation changes.
| Meta metric | ||
|---|---|---|
| Avg CPC | £0.26-£0.50 | £0.30-£2.00 |
| Avg CPM | £8-£16 | £5-£12 |
| Avg cost per lead | ~£5.83 | £6-£10 |
| Avg ROAS | 4.2x (combined Meta) | |
| Q4 CPM spike | +60% or more vs annual average | |
LinkedIn costs
LinkedIn is the most expensive paid social platform by a wide margin. Average CPCs in the UK range from £2.00 to £6.25, and CPMs sit between £20 and £35 for most B2B campaigns, according to The B2B House’s 2026 benchmark report. That is three to five times what you would pay for equivalent reach on Meta.
That higher cost reflects the audience. LinkedIn lets you target by job title, seniority, company size, and industry with a precision that no other platform matches. If you are selling to CFOs at mid-market SaaS companies, LinkedIn can put your ad in front of exactly that audience. Try doing that on Facebook.
Where LinkedIn delivers is lead quality and conversion. LinkedIn’s native Lead Gen Forms convert at 15% to 20%, compared with 4% to 9% for most website landing pages. For B2B services, the average cost per lead sits around £40 to £80, which sounds high until you consider the deal values involved. A £60 lead that converts to a £50,000 contract is cheap.
| LinkedIn metric | UK benchmark |
|---|---|
| Avg CPC | £2.00-£6.25 |
| Avg CPM | £20-£35 |
| Lead Gen Form conversion rate | 15-20% |
| Avg cost per lead (B2B) | £40-£80 |
| Avg CTR | 0.55-0.80% |
LinkedIn works best when deal values justify the cost per lead. For B2C or low-value transactions, the economics rarely stack up. For professional services, technology, recruitment, and enterprise sales, it remains the strongest B2B paid social channel available.
TikTok costs
TikTok offers the lowest entry point of the major platforms. UK CPMs typically range from £4 to £8, and CPCs sit between £0.30 and £1.20. For brands looking to build awareness or reach younger demographics at scale, TikTok currently delivers more impressions per pound than Meta or LinkedIn.
Conversion rates are improving. TikTok’s average conversion rate rose to 1.34% in 2025, up from 1.11% the previous year, according to Lebesgue’s TikTok benchmark data. That is still below Meta’s conversion rates, but the gap is narrowing, and for certain product categories (fashion, beauty, food, entertainment) TikTok conversion performance is competitive.
Budget requirements are worth noting. TikTok requires a minimum of around £400 at campaign level and £40 per day at ad group level. For meaningful testing and optimisation, plan for £700 to £1,000 in the first month. That is higher than Facebook’s minimums but lower than LinkedIn’s practical floor.
Creative demands are different too. TikTok ads that look like ads tend to underperform. The platform rewards native-feeling content, which means production costs can be lower but creative refresh rates need to be higher. Budget for creating more variations, not more polished ones.
YouTube costs
YouTube operates on a different cost model to most social platforms. Rather than CPC or CPM, most YouTube campaigns are priced on a cost-per-view (CPV) basis, where a “view” means someone watched at least 30 seconds of your ad or engaged with it.
UK CPV rates range from £0.04 to £0.25, with most campaigns landing between £0.06 and £0.15. CPMs range from £3 to £12, with significant variation by content category. Finance and insurance niches carry CPMs of £5 to £12, while lifestyle and entertainment sit closer to £2 to £4.
YouTube Shorts ads are bringing costs down. Average Shorts CPMs sit around £3 to £4, and brands typically pay £0.08 to £0.25 per view for Shorts placements. As YouTube pushes more inventory into Shorts, this is becoming a viable lower-cost format for reach campaigns.
| YouTube metric | UK benchmark |
|---|---|
| Avg CPV (skippable in-stream) | £0.04-£0.25 |
| Avg CPM | £3-£12 |
| Shorts CPM | £3-£4 |
| Q4 CPM increase | +40-60% |
YouTube’s role in a paid social plan is different to Meta or TikTok. It sits closer to TV and VOD in terms of audience mindset: users are there to watch content, not scroll a feed. That makes it stronger for consideration-stage messaging and longer storytelling, but less effective for direct-response click campaigns.
Pinterest and Snapchat costs
Both Pinterest and Snapchat are smaller platforms in terms of UK ad spend, but they offer lower costs and strong performance in specific categories.
CPCs in the UK sit between £0.50 and £1.00, with CPMs of just £2 to £5. Those are some of the lowest costs in paid social. The trade-off is audience size and intent: Pinterest works well for retail, home and interiors, fashion, and food, where users are actively browsing for ideas and products. Outside those categories, scale is limited.
Its real strength is purchase intent. Users are often in a planning or buying mindset, which means the gap between ad impression and conversion can be shorter than on platforms where people are primarily there to socialise.
Snapchat
Snapchat CPCs sit around £0.70 to £1.00, with CPMs of £3 to £8. The platform’s audience skews younger (16 to 30) and engagement tends to be high with AR lenses and interactive formats. For brands targeting that demographic, Snapchat can deliver reach at a competitive cost.
Minimum daily budgets are low (around £4), making it accessible for testing. But the creative formats are platform-specific, so expect to invest in Snapchat-native content rather than repurposing Meta assets.
| Platform | CPC | CPM | Best use case |
|---|---|---|---|
| £0.50-£1.00 | £2-£5 | Retail, home, fashion discovery | |
| Snapchat | £0.70-£1.00 | £3-£8 | Youth demographic, AR, awareness |
How to compare costs across platforms
One of the most common mistakes in paid social budgeting is comparing platforms on CPC alone. A £0.30 click from Facebook and a £4.00 click from LinkedIn are not comparable if the LinkedIn click converts to a qualified lead worth £5,000 and the Facebook click bounces.
What matters is the cost per meaningful outcome: cost per lead, cost per acquisition, or return on ad spend. A platform with a high CPC but a high conversion rate can be more efficient than a cheap platform where most clicks go nowhere.
Here is a simplified framework for thinking about which platform fits which role:
| Objective | Best platforms | Typical cost per lead |
|---|---|---|
| B2C lead generation | Facebook, Instagram | £5-£15 |
| B2B lead generation | LinkedIn, Facebook | £40-£80 |
| Ecommerce sales | Meta (Advantage+), Pinterest | ROAS-based (target 4x+) |
| Brand awareness (broad) | TikTok, YouTube, Meta | CPM-based (£4-£12) |
| Youth audience reach | TikTok, Snapchat | CPM-based (£3-£8) |
There is also a compounding effect from running campaigns across multiple platforms. According to First Page Sage’s 2026 ROAS report, advertisers running coordinated campaigns across three or more platforms outperform single-platform strategies by 25% to 35%. This does not mean spreading budget thinly across everything. It means choosing two or three platforms that serve different funnel stages and investing enough in each to generate meaningful data.
So the real question is not “which platform is cheapest?” but “which combination of platforms gives us the best cost per commercial outcome?” That requires looking at the full customer journey, not just individual channel metrics. It is the same reason integrated media planning outperforms channel-by-channel budgeting.
Frequently asked questions
What should a UK business spend on paid social in 2026?
It depends on your objectives, sector, and audience. As a starting point, most UK businesses investing seriously in paid social spend between £2,000 and £10,000 per month across platforms. Smaller businesses testing a single platform can start from £500 per month, but meaningful optimisation requires enough data to learn from, which usually means at least £1,000 per month per platform.
Which social platform has the lowest advertising costs?
Pinterest and TikTok currently offer the lowest CPMs in the UK market (£2 to £8). Lowest cost does not always mean best value, though. Platform choice should be driven by where your audience is and what action you want them to take, not by which platform offers the cheapest impressions.
Why are paid social costs increasing in 2026?
Three main factors: more advertisers competing for the same inventory, platform shifts toward higher-cost video formats, and automation tools like Meta’s Advantage+ concentrating bidding on overlapping audiences. IAB UK reports that total UK social spend grew 21% year-on-year in 2025, and that level of demand naturally pushes auction prices up.
Is LinkedIn advertising worth the higher cost?
For B2B companies selling high-value products or services, yes. LinkedIn’s targeting precision and Lead Gen Form conversion rates (15 to 20%) mean the cost per qualified lead is often competitive despite the higher CPC. For B2C or low-value transactions, other platforms will almost always deliver better economics.
How do paid social costs compare to Google Ads?
Average Google Ads CPCs in the UK range from £0.50 to £3.00 for Search and £0.30 to £1.50 for Display, depending on industry. Paid social CPCs are generally lower (except LinkedIn), but the intent is different. Google captures existing demand from people actively searching. Paid social creates demand and builds awareness. Most effective strategies use both, with budget allocated based on where you need growth.
Planning your paid social budget
Cost benchmarks are useful for planning, but they are averages. Your actual costs will depend on your targeting, creative quality, landing page experience, and how well your campaigns are structured and optimised over time.
Brands getting the best returns from paid social in 2026 are not necessarily the ones spending the most. They are the ones measuring the right things, testing across platforms, and making budget decisions based on commercial outcomes rather than channel-level vanity metrics. If your current reporting only shows you CPCs and impressions, you are probably making decisions with incomplete information.
