Quick Tips
Jump-start your understanding with these essential tips
A correct EPC rating makes the upgrade shortlist more realistic and avoids over-promising potential savings. You can find your EPC certificate for free on GOV.UK.
Measures like smart heating controls and loft insulation often pay back in under 3 years. Start with these before looking at bigger projects like heat pumps or solar panels.
Improving insulation first means your new heating system can be smaller and more efficient — saving you money on both installation and running costs.
The Boiler Upgrade Scheme (BUS) offers up to £7,500 for heat pumps. The Great British Insulation Scheme can fund loft and cavity wall insulation. Check eligibility before paying full price.
Step-by-Step Guide
Follow these steps to get the most from this tool
Start with your postcode, property type, bedroom count, and current EPC rating. These inputs determine your estimated energy consumption, annual bill, and which upgrades are suitable for your home.
💡 Pro Tips:
- •Use the latest EPC certificate if available — find yours free on GOV.UK.
- •If unsure about your EPC, D is the UK average and a reasonable starting point.
The tool estimates your annual energy bill and carbon footprint based on your property details and live fuel prices. Compare your estimated bill with the UK average and your regional average to understand where you stand.
💡 Pro Tips:
- •The estimate uses your actual energy supplier rates where available via the Octopus Energy API.
- •Carbon emissions are calculated using official BEIS conversion factors.
Use the Quick Wins and Long-term tabs to compare upgrades by payback period, annual savings, and carbon reduction. Quick wins typically pay back in under 5 years, while long-term investments suit homeowners planning to stay 10+ years.
💡 Pro Tips:
- •Check the Government Grants section — you may be eligible for free or subsidised insulation or heat pump funding.
- •Download your personalised report to share with installers or compare quotes.
Advanced Topics
Deep dives for advanced users
Some upgrades work better in a specific order. For example, improving insulation before installing a heat pump means the heat pump can be smaller and cheaper, while still keeping your home warm. The tool flags dependencies where relevant.
A higher EPC rating can increase your property value and may qualify you for green mortgage products with better rates. From 2028, all rental properties in England and Wales will need at least an EPC C, making upgrades essential for landlords.
Payback period measures financial return, but some upgrades — like double glazing or floor insulation — also significantly improve comfort and reduce draughts. Consider both financial and quality-of-life benefits when prioritising.
