HIU servicing & repair

For flats with communal or district heating — Gas Safe registered, HIU certified

Flats & apartments

HIU engineer for London flats

Many new-build flats get heating and hot water from a heat interface unit (HIU) fed by a communal or district heating system. When it fails, you have no hot water or heating and the building boiler cannot help. We service and repair HIUs for residents, landlords, letting agents and block managers.
