A HEREFORD firm says it has had its most successful year yet, despite the coronavirus pandemic. Property maintenance company, GB Electrical & Building Services, is looking towards expansion after say hitting an £18 million turnover in 2020. Founded in 1991, the business has grown from offering electrical installation and repair works, to a full range of building services including construction and property maintenance, with a 157-strong team. Its customers range from residential to commercial clients, as well as public sector organisations like the Ministry of Defence. And it is now recruiting for additional staff across its five offices, covering tradesmen, office staff and management.
