Topaz is Ireland's newest and largest fuel and convenience brand, with over 400 stores right across the country. Topaz marks a change for the better, where service, convenience and quality standards are as important as our responsibilities to the environment. Topaz has the largest network of service stations in the country. It fuels large sections of Irish industry; and it supplies more Irish homes with heating oil than any other company. Its non-fuel retail business (responsible for, among other things, the sale of 4 million cups of coffee every year) is a critical part of its identity, and grows every year.
