Where Do We Come From?


Butler & Young were formed as Mechanical and Electrical Engineering Consultants.


The company formed a Building Control and Fire Safety Consultancy Division. The contracts obtained at this time were with various government departments, which included term contracts with the then Lord Chancellors Department (now known as The Court Service); HM Customs and Excise; Crown Prosecution Service; Benefits Agency Estates; and the Employment Service in Scotland.


The Building Control and Fire Consultancy Division was made independent of Butler & Young Associates and was incorporated as a limited company.


Butler & Young Limited were appointed as one of the first Approved Inspectors for all building types by the Office of the Department for Communities and Local Government (formerly ODPM & DETR).


The company was restructured creating a holding company called the BYL Group, which is responsible for a group of five companies, namely Butler & Young Limited; Trenton Fire Limited; BYL (Construction Consultants) Limited; Butler & Young (Scotland) Limited; and BYL Training Limited.

2007 to 2019

The Group was rebranded the Butler & Young Group which now is the umbrella company for Butler & Young Building Control, Trenton Fire and Butler & Young Consultants. The Group has continued to consolidate its position as the leading compliance consultancy incorporating a building control body. It is a thought leader and is proactive in raising industry standards and providing value to the construction industry, government and wider society.
