Stop paying for snapshot audits.
Audit your buildings every single day.
HeatFlow turns your meters, gateways and plant-room sensors into a continuous energy audit - surfacing waste, faults, distribution losses and savings opportunities the moment they appear, not 12 months after the consultant left.
An audit that never stops working
Traditional energy audits cost £5–£25k, take weeks to deliver and are out of date the moment a boiler trips, a pump fails or a control setpoint is changed. HeatFlow gives you the depth of a full audit with the immediacy of a real-time platform.
Continuous, Not Snapshot, Auditing
Traditional energy audits give you a single snapshot in time. HeatFlow audits your plant rooms and heat networks continuously - every meter, every gateway, every day - so inefficiencies are caught the moment they appear, not 12 months later.
Plant Room Performance Telemetry
Live visibility on flow and return temperatures, heat output, gas input, run hours, and pump performance. The data you wish your spreadsheet had - automatically captured.
Heat Loss & Distribution Loss Detection
Compare boiler-house gas input to total metered heat delivered to apartments. HeatFlow flags excessive distribution losses, oversized plant and poor controls strategies.
Fault & Anomaly Surfacing
Offline meters, flatlines, leaks, consumption anomalies, weak signal, low battery, imbalance - all surfaced as actionable findings rather than buried in a PDF.
Benchmarking Across Your Estate
Compare kWh per m² and kWh per dwelling across sites to identify the worst-performing buildings and prioritise capital expenditure where it pays back fastest.
Audit-Ready Evidence Packs
Export findings as branded PDF and CSV reports. Use them for board sign-off, ESOS, SECR, PSDS bids, ISO 50001 reviews and ESG disclosure.
What a HeatFlow audit typically uncovers
10–25% distribution losses on communal heat networks
Boiler-house gas input vs. metered apartment heat reveals losses that no manual audit picks up - and gives you the evidence to justify pipework insulation, balancing or re-commissioning.
Oversized boilers cycling 30+ times an hour
Run-time analytics and modulation data expose plant that is destroying its own efficiency. The fix often costs nothing - controls re-tuning - and saves 5–15% gas.
Faulty or stuck heat meters quietly costing money
Flatlines, drift and zero-readings are flagged automatically. We've seen single-building recoveries of £20k+/year once metering integrity is restored.
Domestic Hot Water (DHW) overheating losses
DHW systems frequently run hotter than required. HeatFlow's temperature telemetry surfaces this and lets you safely lower setpoints with full Legionella audit trail.
Frequently Asked Questions
What is energy audit software?
Energy audit software replaces one-off consultant audits with continuous monitoring of energy-using assets - meters, plant rooms, HVAC, controls - to identify inefficiency, waste and faults in real time. HeatFlow.ai is energy audit software focused on UK heat networks, plant rooms and communal heating in large buildings.
How is this different from a traditional energy audit?
A traditional audit is a one-week snapshot that ages quickly. HeatFlow runs an audit every minute of every day, learning your baseline and surfacing deviations the moment they happen. You get the depth of an ESOS-style audit with the immediacy of a live dashboard.
Does HeatFlow help with ESOS, SECR or ISO 50001?
Yes. HeatFlow provides the auditable consumption data, baselines and savings evidence those frameworks require. Reports are timestamped, source-tagged and exportable in formats suitable for compliance submissions and external assurance.
Can I use HeatFlow if I already have BMS / SCADA?
Absolutely. HeatFlow complements BMS and SCADA by adding metering-grade measurement, fault detection and customer-facing reporting on top. We integrate via wM-Bus, LoRa, NB-IoT, Modbus, CSV and API.
How quickly will an audit show results?
Most clients see actionable findings - distribution losses, faulty heat meters, oversized plant or anti-cycling controls issues - within the first 30 days of monitoring.
Is this suitable for buildings with energy-saving devices already installed?
Yes. HeatFlow is the ideal customer frontend for energy-saving device manufacturers, controls retrofits and boiler optimisation kit. We measure, verify and report the savings your hardware delivers.
