Lease Advisory & Business Rates Specialist

James started his career in the London West End office agency market in 1987, moving across to the City office market in 1991 to deal with lease consultancy / professional advisory work.  James then moved to the niche City practice Ingleby Trice to head the Lease Advisory team before moving to Allsop as Partner in 2006.  He continues to specialise in Lease Advisory work in the City, City Fringe and Midtown market for landlords and tenants. 

James works closely with his agency teams, refining where refining any valuation significant clauses in new leases on acquisition and disposal appointments. “Working closely with our agency teams together with my forensic lease analysis inputs makes a world of difference to the outcome to a rent review or lease renewal.”

This collaborative approach also applies to his dilapidations appointments; he brings unique skills to the table, incorporating a sound application of the legal arguments alongside a close understanding of the market place – increasingly important where negotiations hinge around the intention of landlords on the future of vacated premises.

James looks beyond the obvious aspects such as terms of the lease, market conditions etc to consider the wider business objectives of the client, blending valuation and legal expertise to achieve exceptional results. “My work is all about the detail”.
