MADDOX ART ADVISORY
Art Investment Advisory for Collectors & Investors
Build a considered art portfolio with guidance from Maddox Gallery’s specialist art investment Advisory Team. Combining art market intelligence, private access and personalised support, we help clients acquire works they understand, enjoy and can hold with confidence.
Overview
Art advisory shaped by access, insight and long term vision

Our team offers discreet guidance across sourcing, research, negotiation, documentation, logistics and resale planning, with advice shaped around each client’s goals, budget and time horizon.

- Evidence-led recommendations: Guidance informed by provenance, condition, pricing history, artist momentum and current market context.

Why Maddox Gallery
Collect with Confidence
With over 10 years of consistent double-digit returns, Maddox has helped clients build and resell art portfolios with insight, discretion and market expertise. To date, more than 2,100 works have been resold through Maddox for a profit, with over £13.5M distributed to clients and more than £100M in artworks resold on their behalf.
Past performance is not a reliable guide to future results. Artwork values can fall as well as rise, and resale is not guaranteed.
