About Us

Our mission is to provide the ACD service that adds the greatest value, through superior industry knowledge, service quality and fund expertise.

IFSL provides expert independent ACD and fund administration services – allowing you to get on with what you do best, whether that’s investment management or advising clients, secure in the knowledge that highly experienced specialists are managing all aspects of fund operation and oversight on your behalf.

We take a client-led partnership approach, working closely with you and ensuring high levels of regulatory awareness and oversight that protect your interests and those of your investors.

Fund services

Few independent ACD service providers can claim the same level of experience and expertise across the full spectrum of fund services: fund administration, transfer agency, compliance oversight, risk management, distribution, investment management and finance.

Key strengths

All aspects of collective investment scheme operation, management, oversight and distribution are covered by experienced and highly knowledgeable teams within our organisation. We believe that only a business with these capabilities in-house can truly have the expertise to provide the effective and robust oversight expected by both the regulator and investors.

Our in-house expertise also equips us to deliver the same standards of management and oversight to external service providers, where that approach is best suited to your business model.

Stability and expertise

We have the financial strength and stability that comes with being part of the privately owned Marlborough group of companies, which has been managing funds since 1986 and has over £10 billion of assets under management. The group has achieved consistent long-term growth, with unusual longevity of tenure among the directors and core team. Being part of a group that includes a leading fund management business, Marlborough Fund Managers, also means we have an invaluable practical understanding of the fund management industry.
