regulation note / 02

UNITED KINGDOM / ONLINE SAFETY ACT / OFCOM / 28 AUG 2026

Two age checks.
Seven UK blocks.

In its official 28 August update, Ofcom reported two sites that introduced age assurance — a term covering age verification or age estimation — and a further seven that blocked access from the United Kingdom. These are outcomes described in that update; they do not yet tell us the effect of either one.

What you gain: separate what Ofcom counted from what you might assume about protection, effectiveness, or the rest of the world.

Next: one fictional door, two decisions, then the boundary the count cannot cross.

OFCOM · OFFICIAL UPDATE 2 AGE ASSURANCE / 7 UK BLOCK NO SERVICE NAMES

The decisive source is Ofcom's update. The Act clarifies the vocabulary; the door in the drawing is fictional.

age assurance 2 sites introduced an age-assurance measure
UK block 7 sites blocked access for people in the UK
in this update 9 reported outcomes: 2 + 7
fictional door / two reported paths THE SAME SERVICE

Switch the fictional door

PATH A / CONCEPTUAL

The door stays. A filter appears.

In Ofcom's language, the site can introduce age assurance to prevent access by children in the UK. This page does not assess the method or show a real service.

PATH B / CONCEPTUAL

The door no longer opens from the UK.

Ofcom calls restricting access from UK IP addresses a geoblock. That is a jurisdictional boundary, not a claim this page can make about protection outside the UK.

Path A: the door stays; a filter appears.

01 / the count

What 2 + 7 actually says

Ofcom did not publish a leaderboard. It published an update about concrete compliance results: two sites introduced age assurance, while a further seven blocked UK access.

That gives us simple, checkable arithmetic: 2 + 7 = 9 site-level outcomes in this update. “Outcome” does not mean “equal safety measure”; it means Ofcom described that change.

RECONCILIATIONOFCOM / 28 AUG
Outcomes Ofcom reports in the update
pathsiteswhat it supports
age assurance2introduced a measure
UK block7stopped access from UK
total in update92 + 7

The unit is “named site and described outcome”, not “all regulated services”.

Next question: do these two outcomes change the same door?

02 / two exits

Two paths, one jurisdiction

01UNITED KINGDOMwhere the boundary described here applies
02FICTIONAL SERVICEconceptual object, not a real provider
03AADD A FILTERage assurance for children's access
03BCLOSE FROM UKgeoblock for UK users
A

Product change. Ofcom says two sites implemented age assurance after engagement with their providers.

B

Access change. A further seven sites blocked access for people in the UK; the update does not turn that into a global measure.

Now we can separate the geography of the outcome from the Act's legal vocabulary.

03 / vocabulary

The Act names the measure

“Age assurance” is Ofcom's working term. The Online Safety Act 2023 uses two forms: age verification and age estimation.

AGE VERIFICATION

Age verification

A measure designed to verify a user's exact age — a legal category, not an evaluation of a provider.

AGE ESTIMATION

Age estimation

A measure designed to estimate a user's age or age range, in the terms defined by the Act.

The important limit: naming the measures in law does not mean every method is equally effective, or that the two sites' outcome measures protection achieved.

The terms are checked against the Online Safety Act 2023, including section 230 and the specific duty in section 12.

So what is missing from such a clean count?

04 / do not extrapolate

What 2 + 7 cannot tell us

01

Not who

Ofcom describes categories and outcomes, but this page does not name or identify the sites.

02

Not how many

We do not have all comparable services here. Nine is the update's outcome count, not a market denominator.

03

Not how well

The count is not an effectiveness test, a protection rate, or an estimate of harm avoided.

04

Not what follows

This update does not tell us whether a block stays, changes, or what happens outside the UK.

So “something changed” is a smaller claim than “the problem was solved”.

05 / the map edge

“Geoblock” has a clear edge

UKaccess restrictedwhat Ofcom says
OUTSIDE THE UKnot measured herewhat the update does not say

Ofcom explains a geoblock as restricting access from UK IP addresses. On this page, jurisdiction does not become a map of global protection: the record does not tell us what happened to users in other countries.

An outcome about access from the UK is not a universal measure of online safety.

interpretation limited to Ofcom's record

The essential distinction remains: an observed change is not automatically a measured effect.

06 / the allowed claim

Reported change is not measured effect

Ofcom says it measures results by the change it delivers. For this update, the change is observable: two sites introduced age assurance and seven blocked the UK.

WE CAN SAYOfcom reported 2 + 7 outcomes.supported by the 28 August update
WE CANNOT SAY FROM ITOne path is more effective.that would need other evidence: denominators, measurement, and method

That is the object's small but solid gain: see one rule's incidence in two forms without assigning an effectiveness that the source does not measure.

For responsible reuse, keep the date, unit, and limits beside the number.
