How to Advertise on TikTok in the UK: A Small Business Guide
Updated: 6 days ago
TL;DR: You can start advertising on TikTok in the UK for around £20–£30 a day inside the free TikTok Ads Manager. The app reaches more than half of UK online adults, and its ad costs usually undercut Facebook and Instagram. For most small businesses the winning formula is simple: run native-feeling In-Feed and Spark Ads, let TikTok's AI-powered Smart+ handle the optimisation, and judge everything on cost-per-result rather than views.
Why TikTok Is Worth a Small Business's Time
TikTok is no longer a niche app for teenagers. Ofcom's Online Nation 2025 report found that 56% of UK online adults visited TikTok in a single month, and industry estimates put the UK monthly audience at roughly 25–27 million people (Statista and Sprout Social, 2026).
Just as important as reach is attention. Ofcom measured the average UK user spending around 28 minutes a day inside the app — time spent watching full-screen, sound-on video. For a small business, that is a rare chance to reach a large, engaged audience without a broadcast-sized budget.
TikTok is also a genuine shopping engine. Business of Apps estimated TikTok Shop's UK sales at around £6.4 billion in 2025, so the intent to discover and buy is already baked into how people use the platform.
Setting Up: TikTok Ads Manager and Your First Campaign
Everything starts with a free TikTok Ads Manager account at ads.tiktok.com. You will add your business details, a payment method, and the TikTok Pixel — a small piece of code (or a one-click Shopify or WooCommerce integration) that tracks what people do after they click your ad.
When you build a campaign, TikTok asks for an objective first: reach, traffic, video views, lead generation, or sales and conversions. Choose the one that matches the action you actually care about, not the one that produces the biggest vanity number.
A sensible first-campaign checklist looks like this: (1) install and verify the Pixel; (2) pick a conversion or lead objective, not "reach"; (3) start with broad targeting and let TikTok find your audience; (4) upload three to five different vertical videos; (5) set a realistic daily budget you can sustain for at least a week; and (6) leave it alone for a few days so the system can learn before you judge results.
The Ad Formats That Actually Matter for Small Businesses
TikTok sells a lot of premium formats — TopView takeovers, Pulse placements and Branded Hashtag Challenges — but these run into tens of thousands of pounds and are built for national brands. For a small business, you can safely ignore them.
The two formats that matter to you are both self-serve. In-Feed Ads appear naturally in the For You feed and look like organic videos. Spark Ads let you put paid budget behind a real organic post — your own, or a creator's — so the ad keeps its comments, likes and authenticity. Spark Ads consistently outperform standard in-feed creative, which is why they are the default recommendation for smaller advertisers.
If you sell products, Video Shopping Ads pull items straight from your catalogue and are well worth testing once your Pixel is firing and gathering data.
What It Costs in the UK
TikTok's published minimums are lower than most people expect: a documented $50 per day at campaign level and $20 per day at ad-group level, shown in the UK Ads Manager in pounds. In practice, most advertisers treat around £20–£30 a day as the realistic floor — enough for TikTok's system to gather data and optimise properly.
On a cost-per-result basis, UK CPMs commonly land between £3 and £12 per thousand impressions, and cost-per-click between roughly £0.30 and £1.50, depending on your targeting and objective. Those figures frequently undercut comparable Instagram and Facebook placements, which is a large part of TikTok's appeal for cost-conscious brands.
Whatever you spend, measure it on cost per acquisition or cost per lead — not impressions or views, which are cheap and misleading on every social platform.
Creative and Smart+: Let the Algorithm Do the Heavy Lifting
The single biggest predictor of TikTok success is creative that does not look like an ad. Shoot vertical, keep it sound-on, hook the viewer in the first two seconds, and let a real person talk to the camera. Polished, TV-style films tend to get scrolled past.
On the targeting side, TikTok now pushes Smart+, its AI-powered campaign type that automates audience selection, bidding and creative rotation across Web, App, Lead Generation and Traffic objectives. For a time-poor small business, Smart+ is often the most efficient way to start: feed it several strong videos and a clear goal, and let the machine learning find your buyers.
The catch is that AI is only as good as the creative and the conversion signal you give it. Refresh your videos regularly to fight ad fatigue, and make sure your Pixel is tracking a real, valuable action rather than a soft one like a page view.
Staying on the Right Side of UK Ad Rules
TikTok ads in the UK must follow the ASA and CAP Code like any other advertising. Paid content has to be clearly identifiable as an ad, so if you work with a creator, use TikTok's branded-content and Spark Ads tools and the "paid partnership" label rather than relying on a caption.
Age-restricted sectors — alcohol, gambling and many financial products — carry extra rules and audience-targeting restrictions, and some categories are off-limits to self-serve advertisers entirely. If you operate in a regulated space, read TikTok's advertising policies before you build a single ad.
Quick FAQ
How much does it cost to advertise on TikTok in the UK?
You can realistically start from about £20–£30 a day. TikTok's documented minimums are $50 a day at campaign level and $20 a day at ad-group level (shown in pounds in the UK Ads Manager). UK CPMs typically run £3–£12 and CPCs £0.30–£1.50.
Do I need a lot of followers to run TikTok ads?
No. TikTok Ads Manager works from a business account with zero followers. Spark Ads can boost your own posts or a creator's, but paid reach does not depend on your follower count.
What's the best TikTok ad format for a small business?
In-Feed Ads and Spark Ads. Both are fully self-serve and look native in the feed, and Spark Ads — which put budget behind real organic posts — usually deliver the strongest results on smaller budgets.
Is TikTok only useful for reaching Gen Z?
No. While 18–24s are a large group, TikTok's fastest-growing UK audiences are older, and adults over 25 now make up the majority of users — so plenty of B2C, and even some B2B, brands can find buyers there.
The businesses that win on TikTok aren't the ones with the biggest budgets — they're the ones brave enough to make ads that look like content. Start small, let the platform's AI learn, and put your money behind the videos real people actually want to watch. — Daniel Nikolla, Founder of Merx Marketing
The takeaway: TikTok gives UK small businesses broadcast-scale attention at a fraction of the usual cost — but only if your ads feel native to the feed and you measure real results, not views.
