Key takeaway
What This Development Means
The United Kingdom has laid a new UK-Switzerland conformity assessment agreement before Parliament. Signed on 11 December 2025, it consolidates two existing arrangements and preserves recognition across eight sectors, including chemical GLP and pharmaceutical GMP. The treaty is not yet in force and will require completed UK scrutiny and an exchange of notes with Switzerland.
Is The New UK-Switzerland Agreement Already In Force?
No. The treaty has been signed and laid before Parliament, but entry into force depends on completion of domestic procedures and an exchange of notifications. Businesses should verify the applicable existing agreement and any official commencement notice before changing their conformity route.
Does Mutual Recognition Remove Product Compliance Duties?
No. It allows specified assessment, laboratory or inspection results to be recognised across the two markets. Manufacturers, importers and distributors must still satisfy applicable product standards, approvals, markings, documentation, traceability and market-surveillance obligations in the destination jurisdiction.

UK-Switzerland Conformity Assessment Treaty Reaches Parliament
The UK-Switzerland conformity assessment agreement was published and laid before the United Kingdom Parliament on 14 September 2026. CS Switzerland No.1/2026 was signed in Bern on 11 December 2025 and brings existing mutual-recognition arrangements into one instrument.
The agreement is not yet in force. UK scrutiny under the Constitutional Reform and Governance Act 2010 must be completed and the parties must exchange notifications confirming that their internal procedures are finished. Businesses should continue to rely on the existing applicable arrangements until that process is complete.
Eight Sectors Retain Mutual Recognition
The treaty combines the three sectors covered through the 2019 UK-Switzerland trade arrangement with the five sectors in the stand-alone 2022 mutual recognition agreement. It covers eight sectors:
- Electrical equipment and electromagnetic compatibility.
- Measuring instruments.
- Radio equipment.
- Transportable pressure equipment.
- Outdoor noise-emitting equipment.
- Motor vehicles.
- Good laboratory practice for chemical testing.
- Good manufacturing practice inspection and batch certification for medicinal products.
For chemicals and life sciences, the good laboratory practice chapter supports mutual acceptance of studies, data and compliance-monitoring outcomes. It covers several regimes, including chemicals, biocides, plant protection products, cosmetics, detergents, and food or feed. The pharmaceutical chapter covers relevant inspection results and batch certificates.
These provisions can reduce repeat testing or inspection, but they do not replace the substantive product rules, approvals, labels or market-specific legal responsibilities.
The instrument extends the core agreement's initial duration from three to five years. It also establishes a Joint Committee and duties to notify and consult on regulatory changes. Market-surveillance authorities must cooperate.
Safeguards allow recognition to be suspended for a sector or body where serious non-compliance or safety risks arise.
Territorial Scope And Practical Implications
The treaty applies formally to the whole United Kingdom and Switzerland. The explanatory memorandum distinguishes the routes for the two markets:
- Great Britain will use the bilateral agreement.
- Northern Ireland continues under the EU-Switzerland mutual recognition framework for goods placed on its market, because of the Windsor Framework.
Manufacturers and importers should map each product and test to the relevant annex, market and recognised conformity assessment body. Laboratories and certification bodies should monitor recognition lists and the entry-into-force notice. Distributors should not treat mutual recognition as a substitute for verifying product marking, technical documentation and importer obligations.
Foresight analysis. Combining the agreements should simplify administration without materially changing technical requirements. The main implementation risk is using the right territorial and sectoral route during the handover from the earlier agreements, especially for businesses serving both Great Britain and Northern Ireland.
