William Tribe Lamb founded W T Lamb & Sons as heavy side builders merchants, with his two sons, Bertrand and Antony Ernest, in 1901. They then purchased their first brickworks in 1910.

The company was subsequently run by Antony and Richard Lamb, sons of Bertrand, prior to currenlty being run by the fourth and fifth generations. It is believed that W T Lamb & Sons Ltd is the oldest brick making company in the UK still owned by the founding family.

The company supplied and manufactured bricks for the Victorian buildings of London and the South East with fine handmade bricks, thrown and clamp-fired in Essex, Kent, Surrey and Sussex.

Five generations later, Lambs is still a family-owned business with a focus on providing quality products to the building industry. The fourth generation Group Chairman, Robin Lamb, who joined the company in 1959, worked his way through accounts, roofing and sales departments, before becoming Sales Director, then Managing Director, before assuming his current position. Robin's son James is also on the Board and has been an active non-executive director since 2000.

In 2001, Jonathan Lamb became Sales Director, with his father, Robert, taking over the role as Managing Director.
During this period, the brick industry continued to evolve and Lambs’ success continued, supplying some of the most iconic buildings in the UK.
