MHCLG confirms BASEC as Approved Body 2661

The Ministry of Housing, Communities and Local Government (MHCLG) designates BASEC as an Approved Body for UK Construction Products Regulation testing as of 31st December 2020.

Following the Brexit trade agreements, the question has arisen surrounding mutual recognition agreement of conformity assessments between EU & UK testing and certification bodies around the Construction Products Regulation.

MHCLG position has been confirmed as below:

“The agreement that was reached with the EU at the end of 2020 did not include a provision which would allow for mutual recognition of conformity assessment. Our understanding of the EU Commission’s position is that type test reports issued by UK notified bodies will no longer be valid for the EU market from 1 January 2021. Test type reports issued by UK Notified Bodies will continue to be valid for the GB market, and will allow manufacturers to affix the UKCA marking.

The UK’s position is that it is down to individual UK bodies to decide whether or not to accept EU-issued type test reports to enable UKCA marking and ultimately whether or not retesting is required.”

Details of confirmed designation refer to:

The Construction Products Regulation 2011 (retained EU law EUR 305/2011) as amended by the Construction Products (Amendment etc.) (EU Exit) Regulations 2019 and the Construction Products (Amendment etc.) (EU Exit) Regulations 2020
