A message from our Founder

Lee Brewer
Founder, GYM
For 24 years I worked across every level in one of the UK's largest estate agency group including as a broker, and for the last 14 years in senior leadership. I watched people get treated differently simply because of where they are in their mortgage journey.
If you're ready to buy in nine days, everyone wants to help. If you're nine months away, you're often left to figure it out alone.
I don't believe that's right. Every future homeowner deserves guidance, encouragement and a clear plan, regardless of when they're ready.
That's why I built GYM.
