UK PSTI Product Security Support Periods

PSTI does not prescribe a universal minimum number of support years. The manufacturer sets and publishes a product-specific minimum period and end date; preserve the published commitment and assess any later change against the current Regulations.

Keep the public end date, statement of compliance and internal release records aligned for each product.

3 of 3 questions
Question 1

How long must a PSTI support period be?

The 2023 Regulations took effect on 29 April 2024 and do not set one minimum number of years for every product. For the hardware and software categories listed in Schedule 1 paragraph 3 that can receive security updates, the manufacturer determines a product-specific and must publish the minimum length of time for which security updates will be provided, together with an end date.

The period concerns security updates, not the warranty, ordinary customer support, spare-parts availability, or the product's expected lifetime. Those periods may differ. The published end date is the minimum commitment that the customer can identify for the relevant product.

  • Identify every product model and associated software or service covered by the security-update requirement.
  • Set the period using the product's risks, dependencies, service model, component support, and planned market life; PSTI does not prescribe the calculation method.
  • Approve a calendar end date and the supporting period calculation before the product is made available.

Question 2

What should the support-period record contain?

Keep the product and software identifiers, the approved start and end dates, the calculation rationale, assumptions about third-party components and services, the owner, and the public notice. Preserve dated captures of what customers could see at launch and after each change. A includes software that protects or enhances security, including fixes for issues discovered by or reported to the manufacturer.

The statement of compliance must include the . When a statement is required, the manufacturer and importer must retain it for the longer of 10 years from issue or that defined support period. A manufacturer must not shorten the period after publication. If it extends the minimum and creates a new defined support period, it must publish the new period as soon as practicable.

  • Align the public end date, statement of compliance, product documentation, support site, and internal release records.
  • Record which security updates are within the commitment and how product variants or regional versions map to it.
  • Escalate any proposed shortening or ambiguous change before publication; do not silently replace the historical commitment.

Question 3

How do standards and deemed compliance affect the decision?

The original standards-based deemed-compliance route refers to ETSI EN 303 645 V2.1.1 provision 5.3-13, subject to additional Schedule 1 and Schedule 2 conditions. ETSI TS 103 701 can help structure an assessment, but it is an assessment specification, not a separate PSTI safe harbour.

From 4 December 2025, valid labels under Japan JC-STAR STAR-1 or any level of the specified Singapore Cybersecurity Labelling Scheme can also satisfy listed deemed-compliance conditions. Record the label, scheme version, covered product, and expiry; the route does not remove unrelated duties under the Act.
