Becoming one EA Technology family
For decades, Fundamentals has helped network operators keep voltages within limits, from automatic voltage control relays to support for legacy tapchangers. Together with EA Technology, we now offer a seamless, integrated solution from primary substations to low voltage feeders.
In 2026, EA Technology acquired Fundamentals, the UK's leading provider of voltage control solutions, in a move backed by Summa Equity. Now part of the EA Technology family, Fundamentals continues to operate from Swindon and Oldham, and its products and services are presented under the EA Technology brand.
