Our calculator provides estimates based on typical usage patterns for properties similar to yours. While we strive for accuracy, your actual usage may vary based on specific habits, appliances, and weather conditions. For the most accurate assessment, we recommend using your actual energy consumption from recent bills if available.

Your current energy usage can be found on your energy bills, usually listed in kilowatt hours (kWh). Look for annual consumption figures or add up the usage from 12 months of bills. If you have a smart meter, you can also check your usage through your supplier's app or online account.

According to Ofgem, the energy regulator, the typical domestic consumption values (TDCVs) for a medium user in the UK are approximately 2,900 kWh of electricity and 12,000 kWh of gas per year. However, this varies significantly based on property size, insulation, heating type, and number of occupants.

There are many ways to reduce your energy usage, including: improving insulation, using energy-efficient appliances, installing a smart thermostat, turning down your heating by 1°C, using LED light bulbs, and being mindful of standby power.

Energy prices vary between suppliers due to differences in wholesale purchasing strategies, operating costs, profit margins, and additional services offered. Some suppliers may offer lower rates to attract new customers, while others may charge more but provide better customer service or renewable energy options. The energy price cap set by Ofgem limits the maximum amount suppliers can charge for standard variable tariffs.
