Step-by-Step Guide
Follow these steps to get the most from this tool
Enter your postcode, home type, EPC rating, council tax band, property value, heating type, annual miles, and commute mode. We use a live postcode lookup to place you in the right UK region and apply regional rate tables for energy, transport, water, and council tax.
💡 Pro Tips:
- •Check your EPC certificate for the rating — it directly affects the energy estimate.
- •For council tax band, check your bill or gov.uk/council-tax.
The tool estimates heating, electricity, council tax, water, insurance, maintenance, transport, and broadband, then sums them into a monthly total and annual forecast. A stacked bar chart shows how costs vary by month. Use the monthly breakdown accordion for a row-by-row view.
💡 Pro Tips:
- •Council tax is included by default — toggle water, insurance, maintenance, and broadband on or off.
- •Compare the chart to your actual bills to see where estimates differ.
Enter a second postcode to compare how location affects total running costs. Energy prices, water bills, and transport benchmarks all vary by region. After reviewing, re-run with different EPC ratings or council tax bands to see what changes would save most.
💡 Pro Tips:
- •Use the postcode comparison to test whether a move would save money.
- •Re-run when energy rates, fuel prices, or your council tax band changes.
