UKCA Marking of Construction Products

UKCA Marking of Construction Products

The UK Construction Products Regulations (CPR)

The UK's Construction Products (Amendment etc.) (EU Exit) Regulations 2019 state that any Construction Product covered by a UK Designated Standard must be UKCA marked. The procedures that the manufacturer must follow (the Conformity Tasks) depend upon the type of product.

The UK CPR does not set minimum performance values for products, however it does harmonize the tests that the product must undergo. The manufacturer must declare the performance against these tests. It is then left to national regulations, or the purchasers and users of the product, to decide if the product meets their requirements.

UK Designated Standards and UK Assessment Documents (UKADs)

If a UK Designated Standard exists for a Construction Product, then the product must be assessed using this standard. The list of Designated Standards is published by the Ministry of Housing, Communities and Local Government.

Designated Standards have an Annex ZA.1 which lists the mandatory tests. There may be other tests which are optional, and are not required for UKCA marking.

Products for which no Designated Standard exists can be UKCA marked using a UK Assessment Document (UKAD), which will have a section listing the mandatory tests, serving the same purpose as an Annex ZA.1.

System of Assessment and Verification of Constancy of Performance (AVCP)

Designated Standards have an Annex ZA.3 which sets out the system of AVCP for the product. UKADs will also have a section which serves the same purpose.

There are five ‘Systems’ with different tasks for the manufacturer, and also for Approved Bodies where appropriate.

The Systems contain some or all of the following procedures:

  • Factory production control (FPC)
  • Initial inspection of the manufacturing plant and of FPC
  • Continuous surveillance, assessment and evaluation of FPC
  • Determination of product type on the basis of type testing, calculations, tabulated values or documentation
  • Audit testing of samples taken before placing the product on the market.

The tasks for Approved Bodies depend on the System, and can be one of the following:

  • Testing Laboratory (for System 3): type-testing of samples submitted by the manufacturer
  • FPC Certification Body (for System 2+): initial inspection and continuing surveillance of FPC
  • Product Certification Body (for System 1 and 1+): both type-testing and FPC

System 4 products are the responsibility of the manufacturer, with no Approved Body involvement.

BTTG® – Approved Body 0338.

BTTG®, Approved Body 0338, is accredited as a Testing Laboratory, FPC Certification Body and a Product Certification Body. Our full scope can be found on the UK Approved Bodies database here.
