Online Safety Act fee notification: deadline 11 April 2026

Regulated online services with qualifying worldwide revenue of GBP 250 million or more must notify Ofcom by 11 April 2026 under the Online Safety Act 2023 fee regime. This is the first notification deadline under the Act's fee provisions. Services that fail to notify risk enforcement action.

Change event: Ofcom Online Safety Act fee notification deadline (11 April 2026) Effective 11 April 2026

What is changing

Ofcom has activated the fee regime under the Online Safety Act 2023 (ukpga/2023/50). Regulated services that meet the revenue threshold must notify Ofcom of their qualifying worldwide revenue (QWR) by 11 April 2026.

This is the first ever notification deadline under the Act's fee provisions. Ofcom published its fee statement and notification guidance in November 2025 following a public consultation. The fee regime was activated in the December 2025 to April 2026 window.

Following verification of providers' QWR, Ofcom expects to issue first invoices in Q3 2026.

Who must notify

The fee notification duty applies to providers of regulated services under the Online Safety Act 2023 whose qualifying worldwide revenue (QWR) is GBP 250 million or more in the qualifying period.

QWR covers revenue from all regulated services operated by the provider globally, not just UK revenue. The qualifying period for the initial 2026/27 charging year is the 2024 calendar year (1 January 2024 to 31 December 2024).

Services are exempt from fee duties if their UK referable revenue — revenue arising in connection with relevant parts of regulated services provided to UK users — is less than GBP 10 million in the qualifying period.

What you must submit

Providers must submit details via Ofcom's Online Safety Fees portal. The notification must include:

  • Details of all regulated services operated by the provider
  • Total qualifying worldwide revenue for the qualifying period
  • A breakdown of QWR by revenue type (advertising, subscriptions, transactions, other)
  • A breakdown of QWR by individual regulated service where the provider operates more than one

Ofcom may request supporting evidence or further information to verify the accuracy of submissions.

⚠️ Enforcement consequences

Failure to notify Ofcom by 11 April 2026 may constitute a breach of fee-related duties under the Online Safety Act 2023. Ofcom can take enforcement action including fines of up to 10% of qualifying worldwide revenue or GBP 18 million (whichever is greater). Senior managers face personal criminal liability for failing to cooperate with Ofcom investigations under section 110 of the Act.

❗ What you should do now

Before 11 April 2026:

  • Determine whether your service is a regulated service under the Online Safety Act 2023
  • Calculate your qualifying worldwide revenue for the 2024 calendar year across all regulated services
  • Check whether your UK referable revenue exceeds the GBP 10 million exemption threshold
  • If your QWR is GBP 250 million or more, register for and submit your notification via Ofcom's Online Safety Fees portal
  • Prepare a breakdown of QWR by revenue type and by service
  • Retain supporting financial records — Ofcom may request verification
