Dennis Eagle's history dates back to 1907, when Eagle Engineering Company was incorporated in Warwick. The company specialized in refuse collection vehicles and road sweepers.

In the early 1920s, Dennis Brothers, a builder of buses, fire engines, and haulage lorries, began to produce specialized vehicles for municipal authorities.

In 1971, Hestair Group bought Yorkshire Vehicles Limited in Leeds and Eagle Engineering Co in Warwick. Six months later Hestair bought Dennis Motor Holdings and thereafter managed the businesses as the Vehicle Division of Hestair Engineering. Municipal bodies were made in Warwick by Hestair Eagle (incorporating Yorkshire Vehicles), municipal chassis were made by Dennis in Guildford, cabs were made in Blackpool. Hestair set up a special Environmental Vehicles Division for its waste management activities.

In 1974, the Environmental Vehicles Division was renamed Dennis Eagle.

Dennis Eagle has a long history of innovation in the waste management industry. In 1980, the company introduced the first rear-loading refuse collection vehicle (RRV) to the UK market which are the standard type of refuse collection vehicle used in the UK.

They have been a leader in the development of alternative fuel refuse collection vehicles. In 2004, the company introduced the first compressed natural gas (CNG) refuse collection vehicle to the UK market.

Today, Dennis Eagle is the market leader in refuse collection vehicles in the UK. The company also exports its vehicles to over 40 countries around the world. It is a subsidiary of the Terberg Group, a family-owned company that has been in business for over 150 years. Terberg is a global leader in the production of specialist vehicles for the waste management, port, and logistics industries.

Biffa was founded in 1912 by Richard Henry Biffa as Richard Biffa Limited. The company originally specialized in the removal and sale of ashes and clinker from London power stations. In 1958, Richard Henry Biffa's grandson, Richard Charles Biffa, joined the business and began to grow it organically and by acquisition.

In 1971, Biffa was acquired by British Electric Traction (BET). BET was a major electricity company at the time, and it was looking to expand into the waste management industry. The company continued to grow under BET ownership, and it acquired a number of other waste management companies in the UK. It then went through several ownership changes and today it is one of the largest waste management companies in the UK, providing a wide range of waste management services to businesses and households.
