ABOUT THIS SERVICE
HIU Specialists Across East London
Heat Interface Units (HIUs) are the heating and hot water systems found in many modern apartment blocks and high-rise developments. Unlike traditional boilers, HIUs connect to a communal heat network — and when they develop a fault, you can be left without heating or hot water entirely.
Our engineers are trained and experienced in working with a wide range of HIU makes and models, including those common in Canary Wharf, Stratford, and Bethnal Green developments. We can diagnose faults quickly, carry out repairs, and replace units where necessary.
Whether your HIU is leaking, showing an error code, or simply not producing hot water, give us a call and we'll arrange a visit at a time that suits you.
