New Quadrant Partners

What New Quadrant Partners does

New Quadrant Partners Limited is a London-based private office founded in 2010 that provides integrated fiduciary, legal, tax, and family office services to high net worth UK and international families. The firm operates across four core service lines: Legal and Tax (succession planning, wills, trust and tax advice), Trustee and Executor Services (trust establishment, professional trusteeship, and trust administration under a Trust Corporation with higher fiduciary duty), Corporate Services (family investment companies, partnerships, OEICs, governance, tax and accounts), and Philanthropy Services (charitable foundations and the firm's own Donor Advised Fund launched in 2026). New Quadrant is authorised and regulated by the Solicitors Regulation Authority (SRA) and employs approximately 22 staff including partners, solicitors, trust managers, paralegals, and business support functions, all based at its St James's headquarters.

The business runs on a fee-for-service professional services model with no publicly disclosed pricing and no technology platform, API, or proprietary product beyond the newly launched DAF vehicle. Its go-to-market is relationship-led, supported by content marketing through its News & Insights blog, downloadable guides, and an email newsletter, with distribution primarily through referrals and direct advisory engagement. The firm is privately held with no disclosed external investors, parent company, or M&A activity, and governance is led by Chair Annamaria Koerling and Managing Director Giovanni Borzellino. Customer concentration is high given the bespoke, project-based nature of HNW advisory mandates, and there is no public customer logo list.
