Operation & maintenance
From a single HIU to the complete heat network, we keep critical heating assets safe, reliable and performing.
Choose a planned-maintenance package for the equipment you own, or combine scheduled servicing, reactive support, repairs, reporting and asset care within a single managed solution - from an individual Heat Interface Unit through to substations, secondary networks and energy centres. We service all HIU and CIU types, makes and models.
All Heatiliti service and maintenance plans include labour, administration and access to our 24/7 helpdesk. Each scheme is surveyed and quoted individually, taking account of asset condition, equipment type installed, system complexity and network size. Parts are included where stated below; other parts requirements are quoted transparently before work is undertaken.

Why Heatiliti
Our engineers service every HIU and CIU type, make and model – so you’re not tied to a single manufacturer’s service network. Every plan includes labour, administration and 24/7 helpdesk access as standard, with clear, upfront agreement on what’s included before work begins. And because our teams also design and deliver heat networks, we understand exactly what ‘good’ looks like when we’re servicing one.
Consumer protection, built in
We believe a heat network succeeds only when it delivers dependable heating and hot water, clear communication, fair and transparent charging, responsive support and measurable value for the people who rely on it. Our maintenance service is built around fast, honest response targets and proactive investment in reliability – not just reactive callouts.
FAQs
Which HIU and CIU brands can you service?
All makes and models, both electronic and hydraulic.
What’s included in every plan?
Labour, administration and 24/7 helpdesk access are included across all six plans. Parts are included in the Full HIU/CIU Package, the Full HIU/CIU & Tertiary System Package, and the Total Asset Cover Package; other parts requirements are quoted transparently, scheme by scheme.
How quickly will you respond to a breakdown?
Emergencies such as leaks are targeted at under four hours’ attendance. Loss of heating and hot water is targeted at under twelve hours where vulnerability is identified and under 24 hours otherwise. Routine call-outs are targeted within three working days.
Can you cover the whole network, not just individual HIUs?
Yes. Our Energy Centre / Substation & Secondary Network Care Package and Total Asset Cover Package extend planned maintenance to substations, secondary networks and energy centres.
How is pricing worked out?
Every scheme is surveyed and quoted individually, based on asset condition, installed HIU model, system complexity and network size - there’s no generic price list.
