Irish Market Surveillance Campaign 2019


The Department of Housing, Planning and Local Government has announced a Market Surveillance Campaign in 2019:

The Market Surveillance Authorities responsible for the Construction Products Regulations are carrying out a Market Surveillance Campaign, with the support of the National Building Control Office and The Department of Housing, Planning and Local Government. These campaigns support compliant business and ensure that safe, reliable products are placed on the Irish Market. They also have the effect of regularising bad practice and facilitating a level playing field for business.

The objective of the Market Surveillance Authority is to ensure that only products compliant with the Construction Products Regulation (EU) No 305/2011, are placed on the market.
If you receive a visit, the Market Surveillance Authority will primarily check that you have applied the CE Marking correctly and that you have all the required documentation in place. Please see the attached information note for further details.
