London, April 2025 – Leading online property auction platform BidX1 is delighted to announce the appointment of Stuart Collar-Brown, who is the current president of NAVA Propertymark and brings to BidX1’s expanding team over 2 decades of experience and a proven track record in the property sector.
His passion for the fast-paced and transparent nature of auctions led him to transition from estate agency in 2008, quickly establishing himself as a dynamic and effective auctioneer.
Before joining BidX1, Collar-Brown spent time at Pattinson Auctions (2017-2019) before launching his own venture, My Auction, in 2019, just months before the onset of the Covid-19 pandemic. My Auction later merged with Rocket Auctions, part of Bamboo.
While acknowledging his time within online auction services, Collar-Brown emphasises the invaluable traditional room auction training he received from some of the UK's leading auctioneers, which has shaped his comprehensive approach.
His extensive experience includes key roles at prominent auction houses. He played a significant part in expanding the auction divisions at Strakers, helping to launch successful operations in Swindon and Bath and increasing their auction frequency. He was also part of the initial launch team at Auction House London, contributing to their early growth. Collar-Brown also oversaw a vast network of over 300 estate agency branches during his time at Countrywide Auctions in Kensington.
He joined Propertymark in 2010 and was named president in 2024. His commitment to best standards has helped position him as a thought leader within the auctioneering community. Early in his auctioneering career, his talent was recognised with the Novice Auctioneer of the Year award in 2014, followed by being named Runner-up in the NfoPP Auctioneer Candidate of the Year in 2015, achieving the second-highest exam mark in the UK that year.
Speaking about his move to BidX1, Collar-Brown commented, “Joining such an experienced team at BidX1, with peers I highly respect, is a fantastic opportunity for growth. 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.” He added, "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."
Ultimately, Collar-Brown’s driving force in the auction world is his ability to assist those in genuine need of a property solution. He finds immense satisfaction in helping individuals navigate difficult situations, recalling one particularly rewarding sale: "Being able to sell a house quickly and above reserve for a woman and her son who were survivors of domestic abuse, allowing them to relocate and feel safe, was incredibly fulfilling. It’s this problem-solving aspect, particularly for those facing tough times like bereavement, divorce, or debt, that truly motivates me. I’m fortunate to have the capacity to shoulder some of that stress for my clients."
Oliver Childs is the Managing Director of BidX1 UK. He said: “We are delighted to welcome Stuart Collar-Brown to the team. 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."
