Named after Sir Charles Mclaren, a company director of the Tredegar Iron and Coal Company Mclaren Colliery comprised of three pits that by 1913 employed 1,833 men, but suffered from the economic downturn of the mid 1920s and by 1935 manpower was a third of previous levels.

During the National Coal Board's reshuffling plans for collieries in the UK, Mclaren was linked with Ogilvie Colliery in 1958 and its coal diverted there until it was closed in 1969. On Wednesday 3 of September 1902, an explosion in the No.1 pit killed seventeen men. Prior to this accident McLaren was considered to be a "safe pit." The explosion occurred at about 11.00pm when there were 120 nightshift workers underground.
