Artelia fuses expertise with acquisition of East of Castons, to capitalise on regional development opportunities

International project management, engineering and consultancy business, Artelia, has expanded into the East of England to power a new phase in its UK project consultancy based around global capabilities in new energies, infrastructure and the built environment. Already working in the region on projects such as the restoration of Norwich Castle, Artelia has acquired leading Suffolk-based surveying practice, Castons Consulting Limited and its sister company CCAS Ltd, which specialise in cost management, building surveying, construction health & safety and principal designer services across the public and private sectors. The acquisition will take Artelia’s UK consultant team to over 200 people.


Established in 1895 and headquartered in Ipswich, Castons, has delivered projects across the East of England and enjoys a notable reputation as the go-to consultant of choice for cost and surveying solutions. The team also includes specialists in healthcare and RAAC panel surveying, closely aligning with Artelia UK’s NHS consultancy work. Through the acquisition of CCAS Ltd, Artelia will deepen its existing construction safety and Principal Designer service offering to clients as the new regulatory framework under the Building Safety Act takes effect.


Following the acquisition of insurance reinstatement specialists Austin Newport Group in Birmingham in 2020, now known as Artelia ANG, the purchase of Castons is another step forward in Artelia’s strategy to acquire and grow complementary professional services businesses and broaden its regional reach of local expertise in cost, project, asset management and surveying services in the UK.


“We are delighted to welcome Castons to the Artelia family,” said Mark Day, Managing Director, Artelia UK. “Castons is a hugely respected and long-established business in Suffolk, built on its reputation for service excellence and the experience, knowledge and capability of its people. Artelia has been working in the East of England for a number of years, so the synergies between our two companies will enable us to integrate a full range of professional services and pursue new opportunities around major developments happening in the East of England, including Sizewell C and its associated infrastructure and the Cambridge New Garden Town.”


Peter Dring, Castons’ Managing Director, said: “We are incredibly pleased to have concluded a deal with Artelia Group. To be part of a much larger international business with a shared culture of excellence presents tremendous opportunities for our clients and employees. I can see significant growth opportunities happening around the major developments taking place in Suffolk over the next decade and to have Artelia’s depth of experience in sectors such as new energies, nuclear, industrial and infrastructure is really exciting.”


Castons will continue its operations under its existing name, benefitting from the support and resources of Artelia Group. The integration process will be carried out carefully to ensure a smooth transition and uninterrupted service delivery, with an expanded range of specialised services and a broader geographical coverage.
