Performance baseline
Establish what the network is expected to deliver and what evidence exists to confirm or challenge that expectation.

Performance & Lifecycle Support
Lifecycle support for heat networks where performance depends on commissioning evidence, controls, HIUs, metering, monitoring, operator readiness and resident outcomes.
Performance brief
Long-term performance depends on the evidence, controls and responsibilities carried into operation.
A heat network can look complete at handover but still carry performance risk through weak commissioning evidence, control settings, HIU behaviour, metering gaps, unclear monitoring and poor operator readiness.
DHS helps clients diagnose existing issues and build performance thinking into new schemes before the network becomes a resident-facing problem.
Performance decisions that matter
Performance improves when controls, metering, HIUs and operating evidence are read together.
Use DHS when an existing network is underperforming, or when a new scheme needs operating performance designed into decisions before handover.
Controls strategy
Review sequencing, set points, weather compensation, pump control and control logic against operating performance.
HIU behaviour
Assess dwelling interfaces, flow temperatures, response, maintenance access and resident-facing symptoms.
Metering data
Check whether metering, monitoring and data visibility support diagnosis rather than just billing.
Commissioning evidence
Review whether testing records, controls checks and handover documents support the operating outcome.
Operator readiness
Clarify who owns performance decisions and how issues will be monitored, escalated and resolved.
Optimisation priorities
Identify practical actions before clients commit to major remedial spend.
Resident impact
Connect technical symptoms to comfort, reliability, tariffs, complaints and reputation risk.

Performance evidence board
Performance work starts by making the operating evidence visible.
Useful lifecycle support connects the technical record with what is happening in operation: controls, HIUs, metering data, commissioning evidence, monitoring, operator readiness and resident impact.
- Performance diagnosis grounded in available data and practical observations.
- Controls, HIU and metering issues linked to operating and resident outcomes.
- Optimisation plans prioritised before major remedial spend.
Performance intervention points
Act while evidence can still change the operating outcome.
Poor handover, weak monitoring, control issues, HIU problems and unclear performance responsibility can turn a technically sound scheme into an operational and resident-facing problem.
Before handover
Check commissioning records, controls, metering and operator readiness before responsibility transfers.
Before complaints escalate
Connect resident symptoms to technical, controls, HIU, metering or operating causes.
Before remedial spend
Diagnose the likely cause of underperformance and prioritise practical interventions.
Before lifecycle planning
Clarify monitoring, responsibility, optimisation needs and evidence gaps for long-term stewardship.

Design
Risk to build in
Performance can be compromised if monitoring, metering, controls and handover needs are late additions.
Performance requirements and evidence planning.Commissioning
Risk to evidence
A network can be handed over without enough proof that controls, HIUs and metering are working as intended.

Performance FAQ
Common questions before bringing DHS into this workstream.
Practical questions clients ask before appointing specialist support for this workstream.
When should performance support start?
For new schemes, before handover. For existing networks, as soon as symptoms, complaints, high losses, poor control or unclear data suggest performance drift.
Can DHS diagnose underperforming heat networks?
Yes. DHS can review available evidence, controls, HIUs, metering, commissioning records and operator inputs to identify likely causes and priorities.
What evidence is useful for performance review?
Controls information, meter data, commissioning records, O&M documents, HIU observations, monitoring outputs, complaints and operator notes can all help build the picture.
Is this only for existing networks?
No. DHS can also help design performance evidence, monitoring, metering and operator readiness into new schemes before handover.
How does this help avoid unnecessary spend?
A structured diagnosis can separate symptoms from causes and prioritise the interventions most likely to improve performance.
