Our Business


We have traded successfully for over 100 years by getting the best quality fish to our customers quickly and at a fair price. Sustainable sourcing is at the heart of all we do.

Warehouse production facility

Our original warehouse production facility and head office is based in Vauxhall in central London. This is where orders are taken, where coastal deliveries arrive and where orders are fulfilled and dispatched.
In 2016 we purchased the business and facilities of Simson’s Fisheries in Coulsdon which further extended our deliveries to the south of England.

Our fleet of refrigerated vans delivers from 6am across the Greater London area and our Coulsdon delivery area. Our Vauxhall depot is also able to fulfill secondary orders in the afternoons.


We conduct our business with integrity in an ethical and trustworthy manner and put our customers’ needs at the heart of our culture. In turn, we demand accountability and responsibility from our employees and our suppliers.

Royal warrants

We are proud to be a Royal Warrant holder. We like to think there’s a correlation between quality and service and being awarded the Royal Warrant.

Royal Warrants are a mark of recognition to individuals or companies who have supplied goods or services for at least five years to the Households of HM The Queen, HRH The Duke of Edinburgh or HRH The Prince of Wales.

James Knight of Mayfair is proud to currently have a Warrant from HM The Queen, and has previously also held one from HRH The Prince of Wales.
