The Online Safety Act and OnlyFans: What UK Creators Need to Know

Since 25 July 2025, every site and app in the UK that allows pornography has had to check that its users are adults, using methods Ofcom considers highly effective. For creators, that raised two questions: do I have to do anything, and what does it do to my traffic?

Short answers: the legal duty sits with the platforms, not with you, and the main effect is an extra step for UK fans somewhere between your promo and your page. This guide explains what changed, what fans actually see, and how to plan your promotion around it. It is general information, not legal advice.

What changed on 25 July 2025

The Online Safety Act 2023 gave Ofcom the job of making online services in the UK protect children. For pornography, the deadline was firm. In Ofcom’s words, by 25 July “all sites and apps that allow pornography” had to “use highly effective age checks”, and that applies “whether they are dedicated adult sites or social media, search, dating or gaming services” (Ofcom).

That wording matters for creators. It is not only aimed at the big tube sites. Any service that allows adult content and has UK users falls under it, which includes subscription platforms and the social networks where creators promote.

Who has to comply: the platform, not you

The duty falls on the service. OnlyFans, Fansly, X and the rest are the ones that have to run age checks for UK users and answer to Ofcom if they do not. As a creator you are a user of those services, so there is no registration, licence or verification system you have to run yourself because of this law.

Your existing obligations stay the same: the platform’s own rules on content and verification, and the normal rules on tax. Being on the right side of the Online Safety Act does not change what you owe HMRC, and platforms have reported seller earnings to HMRC since 2024 regardless. Our UK tax guide covers that side.

What UK fans actually see now

A UK fan who wants adult content now meets an age check first. Ofcom’s guidance lists the methods it considers capable of being highly effective (summary by SCL):

• Photo ID matching, where a selfie is compared with an ID document
• Facial age estimation from a photo or short video
• Open banking, where the bank confirms the person is over 18
• Credit card checks
• Mobile network operator checks
• Digital identity services
• Email-based age estimation

What no longer counts: ticking a box to say you are 18, or a payment method that does not require the person to be an adult. Each platform picks its own methods, so fans see different checks on different sites.

It is not only adult sites. By the end of July 2025, mainstream platforms including X, Reddit, Discord and Bluesky had brought in age checks for UK users, with Reddit using the verification service Persona (The Star, 29 July 2025).

What it means for your promotion

Every extra step between a fan seeing you and paying you loses some people. For UK fans there is now at least one more step, and it can appear in two places: on the platform where you promote, if that platform allows adult content, and on the platform where you sell.

Three practical consequences:

• Clean promotion carries further. Content that does not need an age gate reaches UK users without one. That is one reason our own promotion runs Instagram-first, with strictly clean content that points to your link.
• The age check is not your conversion problem to solve. You cannot change how a platform verifies users. What you can control is everything around it: a clear promise in the post, a link page that makes the next step obvious, and an OnlyFans page that sells in the first five seconds.
• Your audience mix may shift. If casual UK traffic converts a little worse than it used to, fans outside the UK become a bigger share of your income. For a UK creator that usually means more American buyers, whose evening falls in your night. Our guide to when to post from the UK deals with that.

What it does not change

The Online Safety Act does not decide what you are allowed to post. That is set by each platform’s rules, as before. It does not make you responsible for verifying your fans; the platform does that. And it does not make you anonymous or less anonymous: fans still see what you choose to show, and geo-blocking still works the way it did. If privacy is your concern, our guide to geo-blocking and privacy covers the options.

How we handle it for UK creators

For the UK creators we manage, the age checks are part of how we plan the funnel: clean, personality-led Instagram content at the top, a short link path, and an inbox that answers quickly once someone has made it through. The chat team works in shifts, so the fans who do get through, from the UK or anywhere else, get a reply at any hour. More on how we run UK accounts is on our UK page.

Questions creators ask

Do OnlyFans creators have to verify their fans’ age in the UK?

No. The Online Safety Act puts the duty on the platform. OnlyFans and other services that allow adult content have to run highly effective age checks for UK users; creators do not run their own.

When did the UK age checks start?

Ofcom set 25 July 2025 as the date by which all sites and apps that allow pornography had to use highly effective age checks for UK users.

What age checks do UK fans have to pass?

It depends on the platform. Ofcom lists photo ID matching, facial age estimation, open banking, credit card checks, mobile network operator checks, digital identity services and email-based age estimation as methods capable of being highly effective. Ticking a box no longer counts.

Does the Online Safety Act change what I can post on OnlyFans?

No. What you can post is still set by each platform’s own rules. The Act changes how UK users are checked before they can see adult content.

Do X and Reddit age-check UK users too?

Yes. By the end of July 2025, X, Reddit, Discord and Bluesky had introduced age checks for UK users, according to UK press reports at the time.
