GHA Coaches was founded by Eifion Lloyd Davies in 1990 and originally based in Corwen before moving to Ruabon in the mid-1990s and since then has expanded with the purchase of a number of other local companies, including:
Despite being founded in north east Wales, with rapid expansion only about half the services currently run by GHA are in this area. The company operates the DeeBee services on behalf of Cheshire West and Chester Council, as well as a number of commercial routes in the Cheshire area. Most of the acquired firms have been absorbed into the main GHA business, though Bryn Melyn and Vale Travel have remained as semi-autonomous companies. Bryn Melyn mainly operates the Shropshire routes, and Vale Travel mainly operates the routes in eastern Cheshire and Staffordshire.
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.
