TikTok has decided what it is worth to Britain, and put the figure at £10 billion a year. The number comes from a report it commissioned from the public-policy agency Public First, with additional modelling by EY, published this month. The figure is a lobbying artifact, but the artifact is the argument. Its point is to recast the platform’s core function, turning discovery into purchases, as national economic infrastructure, so that a curb on TikTok reads as a cost to the economy. At about 0.3% of GDP, the number is built to sound like a power grid rather than an ad network.

The headline total is two different estimates bolted together. Public First values the activity “underpinned by” the platform at more than £9 billion; EY separately counts TikTok’s own UK offices and payroll, and the two are added to clear the line. That larger figure rests on surveys, including one of 1,034 businesses, scaled up to the whole economy. A survey can establish that firms value the platform; it cannot establish what those firms would sell without it.

The report’s most revealing figure is a ratio, not a total. For every £1 of value TikTok generates through its own operations, it credits roughly £16 more to the creators and businesses using it. A 16-to-1 ratio asserts that almost none of that activity would exist elsewhere, that without TikTok the sale does not happen rather than moving to Instagram, a Google search or the shop next door. That assumption is the engine of every commissioned footprint study, and it is the one figure the study never puts to the test.

Three years ago, the same exercise produced a far smaller number. In 2023, Oxford Economics, then TikTok’s firm of choice, valued small-business activity on the platform at £1.6 billion for 2022. The economy did not grow sixfold in three years; the instrument did. The new report widens the frame from “small businesses on TikTok” to all “activity underpinned by TikTok”, and trades an economics forecaster for a public-policy agency. The unit changed because the reader did: no longer an advertiser weighing spend, but a minister weighing a rule.

The reframing lives in the choice of denominator. A company that wants your ad budget reports return on spend; a company that wants your forbearance reports jobs and GDP. TikTok now counts 153,000 jobs against its name. It projects a further £27 billion in e-commerce by 2030, a figure that assumes business adoption keeps climbing at its current pace. These are the categories of the national accounts, chosen so that any restriction on the platform can be entered as a subtraction from the country.


The timing tells you what the number is defending. TikTok put the £10 billion figure into circulation in mid-July. Within days, Ofcom opened a formal investigation into whether the platform’s age checks satisfy the Online Safety Act. The Act’s sanctions reach fines of a tenth of global revenue and, at the far end, a court order restricting the service in Britain. A report that scores the platform as a slice of GDP is the reply written in advance: you cannot cost TikTok out of Britain without booking the loss against Britain.

A company that a court can switch off has every reason to make itself a number no chancellor wants to cross out.

The strongest objection to reading this as spin is that the direction of travel is real. TikTok Shop has become, on the report’s account and the trade coverage that ran with it, one of the UK’s largest beauty retailers, with more than 300,000 small businesses selling through it. If that trade is genuinely additive, sales that would not otherwise exist, then the figure is a floor and TikTok is infrastructure in fact, not rhetoric. Both can be true at once, and that is the difficulty. TikTok plainly moves fashion and beauty sales; the open question is whether a commercial channel should be free to convert that traffic into a constitutional claim on its own survival. The multiplier and the bolted-together total are how the conversion is engineered, and they are the parts a minister should read first.

What TikTok is asking Britain to accept is a unit of account, not a fact. If regulators come to price the platform in GDP the way this report does, then every future limit on it, each age check, each restriction for under-18s, arrives with an economic invoice attached. The line items on that invoice are mundane: a beauty brand’s live sale, a small label’s viral week, the 1.8 million young adults who now treat the app as their first source for what to wear and buy. Britain can read the £10 billion as a measure of what it would lose, or as a lever built to make the loss unthinkable. The difference is whether the number is evidence or terms.
