GHA Coaches was founded by Eifion Lloyd Davies in 1990 and originally based in Corwen before moving to Ruabon in the mid-1990s. It has since expanded with the purchase of a number of other local companies, including:
Despite being founded in north east Wales, only about half of the bus services currently run by the company are now in this area. Services extend as far north as Manchester and Rhyl, to Hanley and Telford in the east, to Shrewsbury in the south and to Barmouth in the west.
Many coaches were inherited with the purchase of Hanmers Coaches, though as with the bus operations, the coach fleet has expanded rapidly. Most coaches carry a livery of silver with red and burgundy stripes and the GHA Coaches name; some are in a similar livery with a white base and the Vale Travel name; some carry a plain yellow livery for school work.
The most common use for the coach fleet is school transport, and GHA has a number of high-capacity coaches dedicated to this work. Coaches are also used for private hire and occasional day trip and holiday work.
In October 2014 GHA launched a 'GHA Gold' brand on the 88 Knutsford to Wilmslow to Altrincham route. They acquired four new Alexander Dennis Enviro200 buses which have WIFI, leather seats, wood effect flooring, a passenger information system and one table on each bus. These vehicles carry branding for the route.
