✦ About Brett
I joined Tyron Ash International Real Estate in September 2019 and have been representing clients across Surrey and South West London ever since. I trade under my own name — The BSG Group — in partnership with the broker, which means you deal with me from first conversation through completion.
In February 2022 I featured on Channel 4's Mega Mansion Hunters — lead storyline of Episode 3 — which gave the BSG Group its national platform. Since then I've focused on what I call the upper quartile: the top 25 % of homes in any local market, where the difference between a confident sale and a stalled one is the calibre of representation.
I work across sales, acquisitions and off-market introductions. Most of my clients come by referral; I keep the list small on purpose so each campaign has the attention it deserves.
“Experts in the Upper Quartile.”
