What our clients say

The team at Castell have supported our rapidly growing business Sochitel with advice and help around our corporate benefits, including company pension schemes, income protection for staff and death in service group benefits. James has provided excellent advice on these work benefits alongside tax-efficient cash-extraction from a share sale. I cannot recommend him highly enough to any growing business. It has been a privilege to be part of their ecosystem of influential clients.

Managing Director

My Castell adviser has really helped my wife and me understand our financial situation and build a long term relationship. Despite the somewhat higher costs and restricted product choice with St. James's Place, we think the advice has been worth it - they are great to deal with.

James has always put my principles and interest first, while assisting me with the appropriate instruments to empower me to manage my savings and risk aspirations. He always makes me cognizant of the pros and cons of each choice, never imposing a product but nudging me in the right direction. Very personal, reliable and thorough in the course of action, which I really appreciate.

The first meeting with my Castell adviser was exactly what I needed. We talked through everything in Detail no judgement, an open and honest conversation. There was no pressure to move forward but I’m delighted I did and can see the money building for the future. Past performance is not indicative of future performance.
