Track decarbonisation with
data that stands up to scrutiny
Energy-saving measures only count if you can prove they work. HeatFlow tracks your gas consumption before and after intervention, calculates carbon savings using UK Government factors, and generates reports that satisfy auditors, councils, and grant bodies.
Stop guessing - start proving your gas savings
Too many organisations invest in energy-saving measures but can't quantify the impact. HeatFlow provides the measurement framework to turn assumptions into evidence - from baseline establishment through to ongoing tracking and certified reporting.
Baseline vs. Actual Comparison
Upload historical gas bills or enter manual readings to establish your baseline. HeatFlow automatically compares post-intervention consumption against your baseline period - month by month, with no spreadsheets required.
Real-Time Savings Dashboard
Watch your gas reduction accumulate in real time. Clear visualisations show kWh saved, percentage reduction, and cumulative cost savings - updated as new readings arrive.
Carbon Savings with BEIS Factors
Every kWh of gas saved is automatically converted to CO₂ equivalent using UK Government BEIS emission factors (0.18 kgCO₂/kWh). Auditable, defensible, and recognised by grant bodies.
Exportable Reports for Stakeholders
Generate PDF and CSV reports showing verified gas reduction, carbon savings, and cost impact. Perfect for board presentations, grant applications, and council reporting requirements.
Intervention Date Tracking
Mark exactly when energy-saving measures were implemented. HeatFlow calculates the precise before-and-after impact so you can attribute savings to specific interventions.
Auditable Data Trail
Every reading - whether from smart meters, CSV uploads, or manual entry - is timestamped and source-tagged. Your savings claims stand up to scrutiny from auditors and funding bodies.
When you need to prove savings
After a boiler upgrade or plant room retrofit
You've invested £50k+ in a new condensing boiler or plate heat exchanger. Your board wants proof it's delivering the projected 20% gas reduction. HeatFlow shows the real numbers - not estimates, not projections, actual measured consumption compared to your baseline.
Grant-funded energy efficiency projects
Public Sector Decarbonisation Scheme, Social Housing Decarbonisation Fund, or local authority grants - they all require evidence of savings. HeatFlow generates the reports these bodies expect: measured reduction in kWh, CO₂ savings using BEIS factors, and cost impact over time.
Building a business case for further investment
The first project saved 18% on gas. Now you want funding for the next building. HeatFlow provides the verified data to make that case compelling - real savings, real carbon reduction, real cost recovery timelines.
Frequently Asked Questions
How do I prove gas savings after installing energy-saving measures?
HeatFlow establishes a consumption baseline from your historical data (uploaded bills or meter readings), then continuously tracks actual consumption after your intervention. The platform calculates the difference automatically, converting savings to kWh, CO₂, and pounds - with full audit trails for verification.
What carbon emission factors does HeatFlow use?
HeatFlow uses UK Government BEIS (now DESNZ) published emission factors. For natural gas, this is 0.18 kgCO₂ per kWh. These factors are updated annually in line with government publications, ensuring your carbon savings reports use the latest recognised values.
Can I upload old gas bills to create a baseline?
Yes. You can upload historical consumption data via CSV, enter readings manually, or even photograph bills for extraction. HeatFlow normalises all data into consistent monthly periods for accurate comparison.
How quickly can I start tracking savings?
You can establish a baseline from historical data and begin tracking within the same day. If you have 6-12 months of previous gas consumption data, HeatFlow can calculate your baseline immediately and start measuring savings from your intervention date.
Is this suitable for proving savings to grant funding bodies?
Absolutely. HeatFlow generates reports specifically designed for grant compliance, showing measured consumption reduction, carbon savings using government-recognised factors, and cost impact. The data is timestamped, source-tagged, and fully auditable.
Do I need smart meters to track decarbonisation?
No. While smart meters provide the most granular data, you can track decarbonisation using manual meter readings, utility bill uploads, or CSV data. HeatFlow works with whatever data you have available.
