BBA HRRB consultation

highlights workmanship and value

engineering concerns.

The British Board of Agrément’s industry consultation into driving up construction product safety standards for Higher Risk Residential Buildings (HRRBs) has revealed that the market considers poor workmanship and uncontrolled value engineering to pose the biggest risks to the built environment – higher even than façade fires.

More than 10,000 viewpoints were collected during the 15-week consultation – entitled Construction Prod-uct Assessment Relating to Higher Risk Residential Buildings – with product manufacturers and BBA certif-icate user groups representing architects, specifiers, warranty providers, insurers, construction managers, funders, building control, and regulators giving their opinions.

The initiative was launched to gather feedback on the role that building product certification plays in the safe construction and refurbishment of HRRBs, the BBA’s proposal of creating an ‘Agrément Plus’ certifica-tion scheme to deal specifically with HRRB safety requirements and to explore wider issues.

“Risks from poor workmanship and unchecked value engineering were on our radar to investigate” said BBA Technical Director Prof Bill Hewlett, “but the strength of feeling about them came as a surprise and is an important finding,”

The consultation reinforced the very clear message that responsibility for safety in the built environment lies with everyone throughout the supply chain, build process and onwards. This is not new information, it ech-oes the principles of Dame Judith Hackitt’s Golden Thread. However, manufacturers, trade associations and user groups the BBA spoke with felt they were shouldering their responsibilities but expressed con-cerns for the domestic RMI sector, pointing out that on-site control is often not practical to independently verify and that design detailing needs close attention. “These questions of workmanship control and uncon-trolled value engineering warrant industry leadership attention, and clearly a focus on domestic RMI is called for,” added Prof Hewlett.


The BBA opened the consultation in February, holding preliminary interviews which yielded a variety of ide-as on how it might approach product certification for HRRBS. From there research partner Mace & Menter validated findings and ran a quantitative survey.

“The norm is to test ideas across stakeholders with regards to Agrément Certification,” said Prof Hewlett. “But a much wider demographic was engaged during this consultation, with a clear mandate to consult with the entire supply chain focusing on the role that building product certification has to play and how it can as-sist in meeting the higher safety standards required for HRRBs as identified in Dame Judith Hackitt’s report ‘Building a Safer Future’. We are incredibly thankful to the wider industry for engaging with us and providing valuable, honest feedback on the BBA and how it can become even more efficient in building a safer, more sustainable industry.”

Five key action points the BBA has taken from the consultation:

  • Further systemisation of BBA processes
  • Strengthened testing regimes
  • Digitalisation of BBA processes and certificates
  • A spotlight on sustainability and ethical sourcing
  • Greater collaboration with industry leadership and certificate users

Data generated from the exercise was extensive and identified that the market has high regard for BBA Agrément Certification and supports its future success; its integrity and fitness-for-purpose attestation are seen as vital and unique. That said, ideas being discussed (particularly digitisation) could lead to a shift in how the BBA interacts with the market and see permanent changes to all certificates and not just those for HRRBs.

In addition, the overarching view of consultees was that a two-tier ‘Agrément’ and ‘Agrément Plus’ ap-proach was not an appropriate way forward. This regime would have seen products with an Agrément Plus certificate attested as fit for use in HRRBs whereas products with an Agrément certificate would not be.

“The preference was that the format of the Agrément certificates should be developed so that fitness (or lack of it) for use in HRRBs is clearly identified,” added Prof Hewlett. “We feel a modular style of certificate can achieve this.”

The BBA’s next step is to consider forming an industry liaison group of certificate users to move forward key discussion points and formalise ideas.
