Spearheading growth in the façade sector
We have strengthened our senior leadership team with the appointment of Chris Holleron in the newly created role of MD of our Certus™ division. The appointment comes as the Building Safety Act and the Building Safety Regulator (BSR) raise expectations across the industry. Certus™, a rigorously tested mechanically fixed brick slip façade system with a 60-year design life, is designed to help clients navigate the BSR processes in a transparent, evidence-based way and is the result of our significant investment in R&D in recent years.
Speaking of his appointment, Chris said: “The Building Safety Act has rightly raised expectations around design information, technical evidence and accountability. Certus™ is well placed to help project teams respond to those expectations, with rigorous testing and a clearly defined approach from early design through to installation.”
Since launching in 2024, Certus™ has already proven itself on live schemes navigating the post-Building Safety Act landscape. At Hallsville Quarter in London, the system cut façade delivery time from 42 to 25 weeks – a reduction that speaks directly to an industry under pressure to move faster without compromising on safety. It has also been deployed at Leven Road – the latter comprising three radiused towers on a riverside site in Poplar where the second staircase amendment rendered the original façade design unviable; Certus™ helped bring the solution.
Building confidence in offsite construction
Chris continued: “Certus™ was born out of collaboration and is built around defined testing, technical evidence and clear installation training and guidance. That gives project teams the documentation they need to make informed decisions from design through to completion. With those foundations in place, we’re in a strong position to grow.”
“I’m proud to be appointed to spearhead it’s growth and to accelerate ACS’s role in the façade sector.”
Chris joins us following a series of senior roles at Voestalpine Metsec, where, as Sales Director, he was responsible for the SFS and Metframe product solution areas, leading separate National sales teams across two distinct revenue streams. His earlier career also included senior roles with Hadley Group as Group Product Manager with involvement in the modular housing sector and Wienerberger as National Sales Manager.
His appointment follows that of Non-Executive Director Stephen Ginger earlier this year; the pair previously worked together at Metsec, leading teams that provided tested solutions and technical support to help design teams develop safe, robust specifications.
Partner of choice for architects, contractors and developers
David Flannery, Managing Director, said: “We’re delighted to welcome Chris to the business. His experience across the offsite and modular sectors, combined with his track record working alongside Stephen at Metsec, will help us strengthen ACS’s position as the partner of choice for architects, contractors and developers navigating this new regulatory landscape.”
Chris concluded: “Stephen and I have previously seen how strong technical evidence, design support and commercial focus can help build confidence in an offsite construction system. I can see the same potential within Certus, and I’m excited to help develop that opportunity at ACS.”
