The President of auction industry body NAVA Propertymark, Stuart Collar-Brown (pictured), is to join property auction platform Bidx1.
His extensive track record in the sector includes key roles at a number of prominent auction houses, including Strakers, Auction House London and Countrywide Auctions.
In more recent times he worked at Pattinson Auctions (2017-2019) before launching his own venture, My Auction, which later merged with Rocket Auctions, which is part of Bamboo.
Prominent thought leader
A prominent thought leader within the auctioneering community, he joined Propertymark in 2010 and became President in 2024
Collar-Brown says of his appointment: “I’m particularly excited by the unparalleled scope to work with both corporate and professional clients.
“The ability to continue my work with existing estate agent relationships across the UK, while also developing strategic partnerships with other agents who want to offer an auction service, is a real advantage. I look forward to continuing to give clients the best advice for their property.”
And he adds, “While I have gained significant experience within other online auction models, my foundational training in the traditional auction room has instilled in me the importance of understanding individual needs and providing tailored solutions.
“Bidx1‘s approach aligns perfectly with my ethos of helping people achieve their property goals, especially those who are facing challenging circumstances.”
We are seeing an uptick in the need for auctions as some of our clients seek to deleverage and manage their risk in the real estate sector.”

Oliver Childs, Managing Director of Bidx1 UK says: “Stuart brings enthusiasm and passion for property auctions, which aligns perfectly with Bidx1 UK’s ethos.
“The current market has become more challenging, so we are seeing an uptick in the need for auctions as some of our clients seek to deleverage and manage their risk in the real estate sector.
“We are particularly pleased that he has chosen to join us. He is widely known for his strong work ethic. Bidx1 are continuing to grow and innovate at a rapid speed, and Stuart’s extensive experience and genuine enthusiasm for the property auction sector make him a real asset to us.”
