# NG Bailey — Engineering and infrastructure services for buildings, energy and digital networks

> NG Bailey is a family-owned UK engineering and infrastructure services group founded in Leeds in 1921. Its operations include building engineering, electrical power networks, digital services and offsite manufacture. It is a specialist installation and systems contractor; on Hinkley Point C, the company participates in the Balfour Beatty Bailey joint venture within the wider MEH Alliance, so the whole-project value is not NG Bailey’s standalone contract.
