A historic St Albans property business is set to begin an exciting new chapter with one of the region’s leading independent property groups.
Castles Property Group has announced the acquisition of Collinson Hall, one of the region’s longest-established and most respected independent property businesses, marking an exciting new era for the iconic St Albans company.
Led by managing director Ronnie Clarke (pictured), Castles Property Group has earned an outstanding reputation for delivering exceptional customer service, local expertise and a genuine commitment to the communities it serves. The addition of Collinson Hall further strengthens the group’s presence across Herts and Beds while safeguarding the future of one of the region’s most established property brands.
For more than 200 years, Collinson Hall has played an integral role in the St Albans property market, helping generations of buyers, sellers, landlords and tenants navigate every stage of their property journey. Throughout its long history, the business has continually evolved to meet the changing needs of its clients while remaining true to the values of professionalism, integrity and exceptional customer service.
Today, Collinson Hall offers a comprehensive range of property services, including residential sales and lettings, commercial lettings and property management, block management, land and development, and professional property advice. This breadth of expertise, combined with its long-standing reputation and deep-rooted connection to the local community, has made it one of the most recognisable and trusted names in Hertfordshire’s property market.
Ronnie said: “Collinson Hall is a remarkable business with an incredible history. For more than 200 years it has adapted, grown and earned the trust of generations of clients, building an outstanding reputation across residential, commercial and property management services.
“We’ve admired the Collinson Hall brand for many years. It has a fantastic reputation, a loyal client base and an exceptional team.
Our aim is to invest in that legacy, strengthen the business for the future and continue delivering the high levels of service that clients rightly expect.
“We see enormous opportunities to build on Collinson Hall’s success whilst respecting the heritage and values that have made it such a well-respected name.”
The acquisition brings together two successful independent estate agencies that share the same values: putting people first, providing honest advice and building long-term relationships within their local communities.
Whilst every growing business evolves over time, the focus remains firmly on ensuring a smooth transition for clients and continuing to deliver the professional, personal service for which Collinson Hall has become known.
Supported by the wider resources, expertise and investment of Castles Property Group, the business is well positioned to build on its strong foundations and embrace new opportunities across every area of the business.
The acquisition also opens the door to continued investment in technology, marketing, staff development and customer experience, ensuring that Collinson Hall remains at the forefront of the St Albans and wider Hertfordshire property market while retaining the independent ethos that has defined the business for more than two centuries.
Ronnie added: “Independent estate agency have never been more important. People value trusted advice, genuine local knowledge and relationships that last beyond a single transaction.
“That’s exactly what both Castles Property Group and Collinson Hall stand for, and together we’re looking forward to writing the next chapter in Collinson Hall’s remarkable story.”
The acquisition represents another significant milestone in Castles Property Group’s continued growth across Hertfordshire and Bedfordshire and reinforces its commitment to protecting and investing in established local brands rather than replacing them.
