First Sentinel Advisory


First Sentinel Advisory Limited is a new niche advisory firm operating with a wider FCA regulated advisory business. Founded by Colin Maltby and Brian Stockbridge, both these professionals who believe in a more comprehensive approach to advisory services.

First Sentinel specialises in corporate/commercial and corporate finance work for UK and international family offices, SMEs, pre-IPO and listed companies. We also have a thriving practice in the arts and media industry, advising on fundraising and contractual issues, as well as a bespoke offering in international investment structuring and succession planning.

We are principally London centric, but have a vibrant association with Latin America, with a rep office in Buenos Aires.

Family Office 

First Sentinel Advisory has a great deal of experience in advising Family Offices on corporate, corporate finance (particularly offshore tax efficient debt structures) and commercial matters both UK centric and internationally. The team can also advise on trustee risk issues, having a broad understanding of succession planning in many jurisdictions worldwide, including the UK, Channel Islands, Switzerland, Singapore, Hong Kong and New Zealand. We also have experience in Latin America and can advise on the complex relationships between civil and common principles.


We can advise on all aspects of corporate, corporate finance and commercial transactional, with a particular emphasis on equity and debt investment. In particular, we bring a completely new aspect to our advice with the benefit of First Sentinel Corporate Finance and experienced corporate finance investment advisers.


Working alongside our division, First Sentinel Corporate Finance, we can advise on all aspects of preparing a company pre-IPO and floating on the markets. In particular we specialise in NEX and AIM.

Listed Companies

First Sentinel Advisory has experience of working with listed companies, both in terms of debt finance and general commercial work.

Further, First Sentinel Plc raises funds for companies and depending on the prevailing circumstances and whether we feel we can help, we can provide an all-in-one service.
