The UK has three main bus manufacturers: Alexander Dennis in Falkirk, Scotland and in Scarborough; Switch Mobility, formerly known as Optare, which is based in Sherburn in Elmet in my constituency; and Wrightbus in Northern Ireland.

That’s an excellent question, and the answer is more complex than you might think. There is no single “UK bus factory,” but rather a mix of manufacturing, assembly, and a strong ecosystem of specialist suppliers.

Here’s a breakdown of where UK buses come from:

1. Major Manufacturers with UK Factories

Several global bus builders have significant manufacturing plants in the UK, which are the primary source of new buses for the country.

• Alexander Dennis (ADL): The UK’s largest bus and coach manufacturer. Headquartered in Falkirk, Scotland, with additional manufacturing facilities in Scarborough (England) and a body plant in Guildford (England). ADL is famous for its Enviro series (e.g., Enviro400, Enviro200). While owned by the global giant NFI Group (Canada), its buses are designed and largely built in the UK.
• Wrightbus: Based in Ballymena, Northern Ireland, Wrightbus is a historic UK manufacturer. It was rescued from administration in 2019 and is now owned by Jo Bamford. It is a leader in zero-emission buses, producing the famous New Routemaster (London’s “Boris Bus”) and the StreetDeck Hydroliner (hydrogen double-decker).
• Switch Mobility: The electric vehicle subsidiary of Ashok Leyland (India). It has a manufacturing and R&D facility in Sherburn-in-Elmet, Yorkshire, focusing on electric single and double-decker buses.
• Optare: Now fully integrated into Switch Mobility, but historically a significant UK brand with a factory
