vs baseline
Couples share heating costs but use more hot water
vs baseline
Standard household size (baseline)
vs baseline
Additional laundry, cooking and shower usage
vs baseline
Significantly higher hot water and electricity demand

Frequently Asked Questions
Are these average utility bills accurate for 2026?
These figures are based on Ofgem's Q1 2026 price cap and current average UK consumption data. Actual bills can vary by 15-25% depending on your property's efficiency, your usage habits, and your specific tariff.
Why are 4 bedroom house utility bills so much higher?
4 bedroom houses typically have 60-80% more floor space to heat than 3 bedroom houses, plus additional bathrooms, larger kitchens, and more bedrooms requiring lighting and heating. The jump from £162 to £203/month reflects this increased energy demand.
