Ms Russell joins from BNP Paribas Real Estate, where he headed the Scottish Business Rates team.

He brings more than 20 years’ experience advising both private and public sector clients across Scotland on appeals, valuation challenges and rates mitigation strategies.

Emily Roberton, co-head of business rates at Newmark, said: “We’re thrilled to welcome John to the team.

“His deep technical understanding of both the Scottish, English and Northern Irish rating systems, combined with his extensive leadership experience, strengthens the depth of expertise we offer our clients and reinforces our position as Scotland’s leading business rates advisors.”

Graham Howarth, head of business rates in Scotland at Newmark, added: “With the addition of John, our Scottish team continues to set the benchmark for excellence in business rates advisory.

“We are currently responsible for 25% of all business rates proposals submitted across Scotland. Of those, 72% of current proposals and 90% of all appeals have been successful – a reflection of the team’s technical depth and advocacy strength.”

Mr Russell said: “I’m excited to join such a highly regarded and fast-growing team. Newmark’s reputation for quality and results in the business rates space is unparalleled, and I look forward to contributing to that continued success.”
