About US

Innovation, customer service and a close-knit family business model have been key to Quantum Underwriting Agencies’ success since Founding Director Alexander Thornton launched the company in 2004.

Building on his 22 years working in the London market, Alex drove Quantum’s rapid expansion from start-up to thriving business. Fellow director Peter Streames came on board in 2009, bringing a wealth of experience from underwriting business in South and South East Asia.

Our personal, close-knit team of insurance professionals not only make Quantum a great place to work: they are our strength when it comes to providing personalised, innovative services in niche insurance markets. We stop at nothing to do the right thing by our clients.

Because we are a family business, every staff member at Quantum Underwriting takes our business personally. This is what helps us to weather the storms of an up and down market - and why we’ve experienced exponential growth in a soft market, where mergers and acquisitions are common. Together the management team has well over a century of experience in the insurance industry. We are backed by a truly wonderful, dedicated and professional support team.

Thanks to the support of our brokers and the commitment of our staff, Quantum has grown to become the largest independent specialist Jewellery, Fine Art and Specie Underwriting Agency in the Southern Hemisphere. Our ethos is to provide brokers with the best niche insurance products and services available - and the best customer service in the southern hemisphere. Our modern, vibrant company is focused on continuous improvement and the very highest standards of service and support.

Quantum is looking to the future, and it is looking bright.
