Alexander Millett

Spear’s Review

Alexander Millett has spent more than two decades navigating the London property market on behalf of (U)HNW clients, building a reputation for discretion as much as results.

He cut his teeth at several major firms, among them Knight Frank, before founding Alexander Millett International. Rather than a conventional agency model, the firm operates along the lines of a private family office, built around close and personal relationships with the families it advises on buying and selling homes.

International instructions now make up a growing share of the business, Millett tells Spear’s. The firm is marketing the first branded residences in the Maldives, and manages properties in, among other locations, Marbella, Barbados and San Francisco. Even so, he says his ‘main source of business remains prime central London around Hyde Park, and most of it is done very discreetly off-market’.

Adviser Profile

Alexander Millett is a boutique international real estate agency built around a simple premise: that property advice at the highest level should feel less like a transaction and more like a trusted relationship. With more than a century of combined experience in residential real estate, the firm offers bespoke advice shaped by professionalism, discretion and genuinely personal client care.

Founded in response to growing demand for prime property advice delivered with the attentiveness of a private family office, the agency works with a select collection of key clients, providing tailored solutions rather than standardised service packages. That founding principle continues to define the business today.

Since its establishment, Alexander Millett has expanded beyond London to include the Maldives, Barbados, New York, San Francisco, Marbella and the South of France. Much of this growth has been driven by word of mouth, with clients, private wealth managers and international banks recommending the firm for its discreet, highly personalised approach.

The agency advises across the full property life cycle, including acquisitions, sales, lettings, property management and estate portfolio management.

A particular strength is its acquisition and advisory service. Drawing on longstanding industry relationships, the team sources on- and off-market opportunities while providing valuation advice through its qualified chartered surveyors. The firm also identifies opportunities to unlock value through lease extensions, planning gain, refurbishment and space optimisation, helping clients navigate complex transactions with confidence.

At its core, Alexander Millett positions itself not as a conventional estate agency but as a discreet, relationship-led advisory practice delivering sophisticated property expertise with the confidentiality and personal attention of a trusted family office.
