The Company

Over the past 20 years, Mark Tunstall has built deep, long-lasting relationships with landlords, tenants and their agents at the premium end of the London lettings market. Many of them return time and again for the personal service they know they will receive; the discretion and integrity they can be sure of; and the insider knowledge they know they will benefit from.

As a firm, we pride ourselves on really getting to know our clients and tenants, and providing frank and honest advice to both parties. We are not in it for the short haul but aim to become trusted advisers. We have an in-depth knowledge of not just one particular area, as is often the case with the employees of larger firms, but of prime central London as a whole. And free of the politics of larger organisations, we can provide a seamless approach to the benefit of both clients and tenants alike.

In short, less is more. We all lead busy lives, so we won’t flag up the irrelevant, but will simply deal with what is important. Whether you are a landlord or a tenant to be, we’ll help deliver your goals with the minimum of fuss.
