Carbon reports that
satisfy auditors and funding bodies
Public money demands proof. Grant bodies, councils, and auditors need verified carbon reduction data - not estimates or projections. HeatFlow generates reports from measured consumption data using UK Government-recognised emission factors.
Reports built for scrutiny
When a council has spent £200,000 of public money on energy efficiency, they need evidence it worked. Not a consultant's projection - measured, verified, auditable proof of gas reduction and carbon savings. HeatFlow provides exactly that.
Automated Report Generation
Generate carbon reduction reports in PDF or CSV format at the click of a button. Reports include measured consumption, calculated CO₂ savings, cost impact, and methodology notes - ready for submission to grant bodies and councils.
UK Government BEIS Factors
All carbon calculations use the latest UK Government BEIS (DESNZ) emission factors. For natural gas: 0.18 kgCO₂/kWh. These are the factors recognised by public funding bodies, local authorities, and the Climate Change Committee.
Public Building Compliance
Councils and housing associations receiving public funds must demonstrate energy savings and carbon reduction. HeatFlow reports meet the evidence requirements for Public Sector Decarbonisation Scheme, SHDF, and local authority grant reporting.
Grant Application Evidence
Applying for energy efficiency grants? You need baseline consumption data, projected savings, and a methodology for verification. HeatFlow provides all three - established baseline, measured post-intervention data, and auditable calculation methodology.
Period Comparison Reports
Compare any two periods side by side: year-on-year, pre/post intervention, or heating season comparison. Reports normalise for weather and occupancy to show genuine efficiency improvements, not just mild winter effects.
Portfolio-Level Carbon Tracking
Track carbon reduction across your entire portfolio - by site, by region, or in total. Ideal for organisations with carbon targets, ESG reporting requirements, or sustainability commitments.
Who needs carbon reduction reports?
Local authorities managing public buildings
Councils with net zero commitments need to demonstrate measurable progress. HeatFlow provides building-by-building carbon tracking with reports that meet public sector audit requirements. Prove that retrofits and efficiency programmes are delivering real reductions.
Housing associations after grant-funded works
The Social Housing Decarbonisation Fund and similar schemes require evidence of savings after completion. HeatFlow tracks consumption from day one of operation, generating reports that show verified energy and carbon reduction against pre-works baselines.
Building managers with ESG commitments
Investors and stakeholders increasingly demand carbon transparency. HeatFlow's portfolio-level reporting provides the data for ESG disclosures, sustainability reports, and progress tracking against published carbon targets.
Frequently Asked Questions
What carbon emission factors does HeatFlow use for reports?
HeatFlow uses UK Government BEIS (now DESNZ) published emission factors. For natural gas, this is 0.18 kgCO₂ per kWh (gross CV). These factors are updated annually and are the standard required by most UK grant bodies and local authorities for carbon reduction reporting.
Can HeatFlow reports satisfy grant funding evidence requirements?
Yes. HeatFlow reports include all elements typically required: baseline consumption data with dates and sources, post-intervention measured consumption, calculated energy savings (kWh), carbon savings (kgCO₂) using government-recognised factors, and cost impact. Reports are timestamped and source-tagged for audit purposes.
How do I report carbon savings for a public building?
For public buildings, you need to demonstrate measured energy reduction against a defined baseline period. HeatFlow establishes this baseline from historical data, then tracks actual consumption after efficiency measures are implemented. Reports can be generated for any period and include the methodology notes required for public sector reporting.
Can I use HeatFlow data for SECR or ESOS reporting?
While HeatFlow is primarily designed for building-level carbon tracking, the consumption data and carbon calculations can inform SECR (Streamlined Energy and Carbon Reporting) and ESOS (Energy Savings Opportunity Scheme) submissions. Data can be exported in formats compatible with standard reporting frameworks.
How are carbon savings calculated for a council-funded project?
Carbon savings are calculated as: (Baseline period consumption kWh - Post-intervention consumption kWh) × BEIS emission factor (0.18 kgCO₂/kWh). HeatFlow automates this calculation using measured consumption data, with options to normalise for weather using degree-day data. Reports include the full methodology for audit transparency.
Can I generate reports for multiple buildings at once?
Yes. HeatFlow supports portfolio-level reporting. You can generate a single report covering all sites, or individual reports per building. Portfolio reports include site-by-site breakdowns plus aggregated totals - ideal for organisations managing multiple public or social housing buildings.
