Foster Slater

We believe that property valuation is about more than just numbers; it is about providing clarity and confidence in some of the most significant financial decisions our clients will ever make. As an independent, family-run firm, we offer a level of personal attention and bespoke service that larger corporate practices often struggle to match.

Generations of Expertise in London’s Residential Market

Our story began in 1992 when John Slater founded the firm, bringing decades of high-level experience from public property companies and RICS leadership. Today, we continue that legacy of excellence. Led by Jonathan Slater and Jonny Wailes, we combine traditional professional values with a modern, data-driven approach to the London and South-East property markets.
