Who is Haven Knox-Johnston Specialist?

Our history

A little bit of background


Welcome to the evolution of Haven Knox-Johnston, with roots dating back to 1992. Born from the merger of “Haven” and “Knox-Johnston Insurance Brokers”, the brand flourished under Amlin’s ownership, later transitioning to MS Amlin Boat Insurance. In 2020, Aston Lark acquired the business, relaunching it as Haven Knox-Johnston. The subsequent acquisition of Aston Lark by Howden in 2022 paved the way for a strategic consolidation, uniting marine insurance entities, including A-Plan Marine, Euromarine Insurance, Howden Fastnet and more recently, Curtis Marine Insurance in Plymouth, adding another great string to our bow.

Our Specialist team dives into unique markets, tackling special risks like personal watercraft, Airbnb boats, and specific enquiries such as blue water cruising yachts. We’ve got you covered for higher-value superyachts and all the complex needs that come with them. Welcome to a future of excellence, where our company’s rich history meets innovation in marine insurance.

You will find our Haven Knox-Johnston Specialist crews located east to west of the UK, based in Maidstone, Southampton, Poole and Plymouth. Here’s a little bit about the brands…
