Why UK Businesses Should Run TikTok Ads Now

If you’re still on the fence about TikTok ads, let me be blunt – you’re leaving money on the table.

I’ve worked in digital marketing for years, watching platforms come and go. I’ve seen Facebook’s golden days, Instagram’s rise, and the LinkedIn resurgence. But TikTok? It’s in a league of its own. It’s no longer just for Gen Z dance trends. It’s an advertising powerhouse, and UK businesses that aren’t leveraging it are missing out – big time.

Let’s talk about why.

Your Audience Is Already There—And Engaged

First, let’s kill the myth that TikTok is just for teenagers. Sure, it started that way, but the platform has evolved – and the numbers back that up. According to DataReportal’s Digital 2026: The United Kingdom report, TikTok’s ads reached 26.8 million UK adults aged 18 and over at the end of 2025 – roughly 48% of the adult population – and that potential reach grew by about 12.5% year on year. This is no longer a fringe channel.

It’s also broadening well beyond Gen Z. The heaviest concentration of users still sits in the 18–34 bracket, but industry trackers consistently show the 35–44 age group as one of TikTok’s fastest-growing UK segments. So if your assumption is “our customers are too old for TikTok,” it’s worth checking that against reality rather than a two-year-old stereotype.

And the best part? They’re engaged. Reported UK usage sits at roughly 45–55 minutes a day for the average user, with a large share opening the app every single day. Think about how often you mindlessly scroll through Instagram stories, then compare it to how TikTok sucks you in, serving up one captivating video after another. That’s the difference. Your ads aren’t just “seen” on TikTok – they’re watched.

Organic Reach Is Insane (And Ads Perform Even Better)

Remember when Facebook and Instagram let you grow your brand organically? Those days are gone unless you have deep pockets. But TikTok? It’s still the Wild West. Even small brands with zero followers can go viral overnight if they post the right content.

Now, pair that organic potential with a smart paid strategy, and you’ve got a serious growth engine. TikTok’s ad platform allows you to hyper-target the right audience based on interests, behaviours, and even how they interact with other content. And because TikTok’s algorithm favours fresh, engaging content, well-made ads don’t just blend in – they perform exceptionally well.

It’s Cheaper Than Facebook and Instagram Ads

One of the biggest reasons UK businesses should be running TikTok ads? The cost.

Facebook and Instagram CPMs (cost per thousand impressions) have climbed steadily over the past few years. TikTok, on the other hand, still tends to come in cheaper for reach. Across 2026 industry benchmarks, TikTok CPMs generally land below Meta’s – reach-focused campaigns are often quoted as 20–40% cheaper on TikTok than the equivalent on Facebook or Instagram. In rough GBP terms, TikTok CPMs commonly sit in the £5–£8 range against Meta’s UK average of roughly £9–£12, with TikTok CPCs frequently in the £0.40–£1.20 band.

Two honest caveats. First, these are broad benchmarks – your actual costs depend on your industry, targeting and creative, so treat them as a starting point, not a promise. Second, cheaper impressions don’t automatically mean cheaper conversions: Meta’s maturity and signal often give it the edge on cost-per-acquisition for direct-response campaigns. TikTok tends to win on upper-funnel reach and discovery; Meta tends to win on efficient retargeting and closing. The smart play for most UK brands is to use both, not to pick a side.

Here’s a rough side-by-side to frame it:

Platform	UK CPM (approx.)	UK CPC (approx.)	Organic reach potential	Best content style
TikTok	~£5–£8	~£0.40–£1.20	High – new accounts can still go viral	Native, entertaining, creator-led, sound-on video
Meta (Facebook/Instagram)	~£9–£12	~£0.60–£1.50	Low – largely pay-to-play for reach	Polished feed/Reels, strong retargeting and offers

(Cost ranges are directional 2026 benchmarks converted to GBP; sources vary and your mileage will too.)

And here’s where it gets even better – TikTok content feels more native. People don’t go on TikTok to be sold to. They go to be entertained. So when you craft an ad that looks and feels like regular content – not a polished, corporate-looking sales pitch – it gets way more engagement.

TikTok Drives Real Sales (Not Just Views)

Let’s be honest, views are great, but if they don’t translate into sales, they’re just vanity metrics. The good news? TikTok is built for discovery-led buying.

The behaviour that makes it work is “See it, want it, buy it.” Users come to be entertained, stumble across a product mid-scroll, and act on impulse – often without ever having searched for it. TikTok Shop and in-app checkout have only shortened that path further. For the right kind of product, that means TikTok can move stock, not just rack up impressions.

Where we’ve seen it land best is with brands that lean into organic-looking, creator-style content rather than traditional polished ads – the ad that doesn’t look like an ad. It won’t suit every product (more on that below), but for visual, impulse-friendly items, the intent-to-purchase gap is genuinely short. If you want the honest head-to-head on where your budget belongs, our Meta Ads vs TikTok Ads breakdown digs into cost, audience and creative side by side.

Brands That Get In Now Will Win Big

Here’s the thing—right now, TikTok ads are still underpriced. But that won’t last forever. If history has taught us anything, it’s that platforms get more expensive as more advertisers jump on board. Facebook was cheap once. Instagram was a goldmine. Then, big brands flooded in, and costs skyrocketed.

The same thing will happen to TikTok. Right now, smart UK businesses have a huge opportunity to get in early while competition is still relatively low. The brands that act now will be the ones dominating later.

Which UK Businesses TikTok Ads Work Best For (And Which They Don’t)

The headline says “every UK business,” but let’s be straight: fit matters. TikTok rewards a particular kind of product and punishes a mismatch. Here’s the honest read.

TikTok tends to work well for:

• D2C and e-commerce brands with visual, demonstrable products – fashion, beauty, food and drink, home and lifestyle.
• Impulse-friendly, lower-consideration purchases where “see it, want it, buy it” can happen in one sitting.
• Brands that can create native, entertaining video consistently, rather than one glossy hero ad a quarter.
• Younger-skewing consumer audiences, though the growing 35–44 base widens this every year.

TikTok tends to struggle for:

• Niche or high-ticket B2B, where the buying committee simply isn’t there in enough volume and the sales cycle is long.
• Highly regulated or restricted categories, where creative and targeting options are limited.
• Businesses that can’t (or won’t) commit to video creative – TikTok is unforgiving of repurposed, static, or obviously corporate ads.
• Very local, low-volume services where the targeting granularity you’d get on search doesn’t exist.

If you’re in the second list, TikTok isn’t necessarily wrong – it just may not be your first pound. Match the channel to the product.

The Ad Formats You Can Actually Use in the UK

TikTok’s self-serve Ads Manager gives UK advertisers plenty to work with. The ones most brands should care about:

• In-Feed Ads – the standard format, appearing natively in the For You feed as people scroll. Your everyday workhorse.
• Spark Ads – ads built from real organic posts (yours or a creator’s, with permission), keeping the likes, comments and shares of the original. They tend to feel more authentic and typically earn stronger engagement than standard in-feed ads.
• Search Ads – now live for UK advertisers, these place you at the top of TikTok’s internal search results, catching people who are actively looking rather than passively scrolling. Increasingly, under-35s use TikTok as a search engine, which makes this a genuinely intent-led placement. We covered the rollout in TikTok Search Ads: what they are and why to care.
• TopView – the premium, full-screen takeover shown as the app opens. High impact, but it’s a managed buy with steep minimums, so it’s aimed at big-budget brand campaigns rather than SMB tests.

For most UK SMBs, the practical starting stack is In-Feed and Spark Ads for reach and discovery, with Search Ads layered in to capture intent.

How to Get Started (Your First Test Budget)

You don’t need a huge budget to find out whether TikTok works for you. A sensible first test:

1. Set a realistic test budget. A few hundred pounds a month (many advertisers start around £20–£30 a day) is enough to gather early signal without betting the farm.
2. Sort tracking first. Install the TikTok Pixel and set up conversion tracking before you spend, or you’ll be optimising blind.
3. Make native creative, not adverts. Shoot vertical, sound-on video that looks like it belongs on the feed. Test three to five variations, not one.
4. Start with In-Feed or Spark Ads. Let the algorithm learn before you judge results, and give it a couple of weeks.
5. Read the right metrics. Watch cost per result and ROAS, not vanity views. Then scale what works and cut what doesn’t.

Treat the first month as learning, not proof. The brands that win on TikTok are the ones that test early, iterate on creative, and stay in while it’s still cheap.

Frequently Asked Questions

How many people use TikTok in the UK? TikTok’s ads reached around 26.8 million UK adults aged 18 and over at the end of 2025 – roughly 48% of the adult population – according to DataReportal’s Digital 2026 report. Reach is still growing year on year.

Are TikTok ads cheaper than Facebook and Instagram ads? For reach, usually yes. 2026 benchmarks put TikTok CPMs roughly 20–40% below Meta’s, with TikTok CPMs commonly around £5–£8 versus Meta’s ~£9–£12 in the UK. But cheaper impressions don’t guarantee cheaper conversions – Meta often still wins on cost-per-acquisition for direct-response, so compare on results, not just CPM.

What’s the minimum budget to start with TikTok ads? There’s no need to spend big to test. Many UK advertisers start at around £20–£30 a day, which is enough to gather early signal. Get your tracking and creative right first so the spend isn’t wasted.

Which businesses should avoid TikTok ads? Niche or high-ticket B2B, heavily regulated categories, and businesses that can’t commit to producing native video tend to see weaker results. TikTok favours visual, impulse-friendly consumer products.

Can you run TikTok Search Ads in the UK? Yes. TikTok Search Ads are now available to UK advertisers, placing you in the platform’s internal search results to capture users who are actively looking – a more intent-led placement than standard in-feed.
