The deal sees the two firms, which both operate in commuter locations outside of the M25 within the A41-M1-A1 corridor, join forces.
Aitchisons, which has been trading since 1935, will now join the Ashtons team of 100 dedicated property professionals, operating from four existing locations.
Karl Judd, managing director of Ashtons said; “We are delighted to welcome some really exceptional people within Aitchisons, to work alongside us as we continue to grow.
“In addition, we also inherit a really sound and progressive business which includes premises in Berkhamsted, a location that we’ve admired for many years.
“As a brand, Aitchisons is trusted by so many loyal clients and is one that mirrors our own ethos so closely, so it’s perfect for us.”
Group chairman, David Goodchild, commented: “Our commercial and professional business has grown rapidly in recent years, now employing over 100 people nationwide. The decision to focus on this core activity, has allowed us to find a brilliant partnership with Ashtons for our residential business.
“The transaction also allows both parties to work strategically together on the crossover between professional and estate agency services, particularly in the land and new homes market.’’
