Saint-Gobain UK & Ireland appoints Dean O'Sullivan as new CEO

Dean will lead Saint-Gobain UK & Ireland in delivering its new Strategic Plan – Lead & Grow – positioning Saint-Gobain as a Solutions Company for residential, commercial and infrastructure. 

Dean is an experienced Managing Director with 25 years’ experience in the construction sector.

Dean has held a number of senior leadership roles within the Saint-Gobain Group in the UK & Ireland starting as a Sales Manager at Saint-Gobain’s Gyproc business in Ireland in 2007, before being appointed to lead the combined Gyproc and Isover Ireland businesses as Sales and Marketing Director in 2011. 

"Saint-Gobain has a strong vision for being a catalyst for a transformed construction sector – lighter, more productive and more sustainable than before"

Dean then moved to the UK to lead Saint-Gobain’s Okarno (formerly Artex) business as Managing Director in 2013 and then its combined Insulation businesses including Isover in the UK in 2019. Most recently, since 2021, Dean has been Managing Director of Saint-Gobain’s UK ‘Interior Solution’s businesses – comprising of Isover and UK drylining and plaster solution brand British Gypsum - where he has overseen a transformation of how the combined businesses support customers in the residential, commercial, infrastructure and retrofit and refurbishment sectors of the UK construction market. 

During this time the Interior Solutions businesses of Saint-Gobain saw British Gypsum become one of the first UK brands to have products carry the Code for Construction Product Information Mark. The businesses also launched a partnership with Pallet Loop to introduce a circular economy for UK Construction pallets, launched the first plasterboard in Europe to be manufactured with 100% recycled gypsum and has overseen the transformation of its road haulage fleet transitioning the majority of the fleet to non-fossil fuel – Hydro- treated Vegetable Oil. 

Dean’s appointment comes as Saint-Gobain’s launches its new five-year strategic plan – LEAD & GROW – which focusses Saint-Gobain on being a solutions company for residential, commercial and infrastructure. Dean will now spearhead Saint-Gobain’s delivery of an enriched solution and service offer adapted for each of the construction market’s needs and being a catalyst for change – helping to shape the entire construction sector towards a more sustainable model.

 “It’s a great privilege to lead Saint-Gobain’s businesses in the UK & Ireland at a time when we release a new strategy that positions Saint-Gobain as a true solutions provider for customers. Saint-Gobain is truly a unique company with an unrivalled breadth of solutions for the entire building industry and expertise made so special by an amazing 360-year history and strong values of care, respect and doing the right things.”
