Turn Data into Smart Energy Decisions
Energy savings start with understanding your numbers. At energysaving.help, our calculators help you estimate usage, potential savings, and renewable payback periods with greater accuracy – empowering you to make decisions backed by real data, not guesswork.
Whether you’re exploring solar panels, heat pumps, EV charging, or tariff switching, these tools give you a clear snapshot of costs, returns, and carbon impact.
- Energy Tariff Comparison Tool
Purpose: Estimate potential savings from switching electricity or gas providers.
Enter your postcode, current supplier, and monthly usage to compare live market rates through MoneySuperMarket – an Ofgem-accredited platform operating under the Confidence Code.
Why it matters:
Even small tariff adjustments can reduce annual bills by hundreds of pounds while allowing you to choose renewable-sourced electricity.
- Solar & Battery Payback Calculator
Purpose: Estimate your solar panel output, storage benefit, and payback period.
Input your roof size, orientation, and local sunlight hours to calculate expected generation and savings under the Smart Export Guarantee (SEG).
Features:
Calculates estimated annual generation (kWh); Models battery storage benefit using day/night tariffs.; Provides indicative payback timeframe and ROI.
- Heat Pump Suitability Estimator
Purpose: Assess whether an air- or ground-source heat pump fits your property profile.
This calculator will analyse insulation level, property size, and current heating method to provide a cost-benefit summary and highlight available grants such as the Boiler Upgrade Scheme (BUS).
Outputs include: Recommended heat pump type and capacity; Estimated upfront and running costs; Grant eligibility and expected emissions reduction.
- Energy Performance Certificates (EPCs) Before you install solar panels, heat pumps, or insulation upgrades, it’s important to understand how efficient your property currently is. An Energy Performance Certificate (EPC) provides a clear rating of your building’s energy performance, highlighting where savings and improvements can be made. Book your EPC quickly and securely through our verified partner EnergyPerformanceCertificates.co.uk. UK-wide network of accredited assessors offering both domestic and commercial assessments. An EPC is a required document for most home sales, rentals, and renewable grant applications, making it a vital step toward smarter energy planning.
- EV Charging Cost Comparison
Purpose: Understand the cost difference between home, public, and renewable-based charging.
The calculator will let users input vehicle battery size, mileage, and electricity tariff to estimate £/mile efficiency and CO₂ offset when charging from solar or grid.
Why it matters:
Helps EV owners decide between installing a dedicated charger or using flexible time-of-use tariffs.
- Business Energy Benchmarking Tool
Purpose: Designed for SMEs to evaluate energy consumption per square metre or per unit of output.
Upload or input monthly usage figures to benchmark against sector averages and uncover areas for savings through efficiency upgrades or renewable integration.
Applicable standards:
Links to ISO 50001 energy management frameworks and ESOS audit requirements.
- Carbon Footprint Estimator
Purpose: Estimate your household or business carbon emissions based on energy consumption patterns.
Outputs can be used to support sustainability reporting, carbon reduction plans, or offsetting strategies.
Features:
Electricity and gas CO₂ equivalents; Optional inclusion of vehicle and travel data; Exportable summary for business reporting.
- Future Integrations
We’re developing additional smart tools to connect directly with partner APIs and AI-driven energy models, including:
Real-time tariff tracker; Dynamic solar yield predictor; Smart home optimization simulator
These will be gradually introduced as part of our commitment to building a transparent, data-centric energy platform for consumers and businesses alike.
