Headline interpretation
Costs are estimates using a single current UK standard-tariff proxy across the full period. This is useful for comparing usage patterns and likely scale of spend, but it is not a reconstruction of actual historical bills.
Spend and usage by period
July-to-July years keep the main heating season together. Calendar-year totals are included because they are closer to how consumers often think about annual spend.
July-to-July year comparison
Calendar-year comparison
Estimated cost over time
Monthly estimated cost combines gas, electricity and standing charges. It shows the consumer-facing impact of seasonal gas demand.
Gas usage over time
Gas has the strongest seasonal pattern. The weekly chart compares equivalent parts of each July-to-July year, while the monthly chart shows the broader trend.
Top gas weeks
Electricity usage over time
Electricity is comparatively steady. The top weeks matter, but the pattern is less dominated by winter than gas.

Best and worst cost periods
These tables use complete Monday-to-Sunday weeks only, so partial first and last weeks do not distort the ranking.

Method and assumptions
Gas conversion used: gas kWh = gas cubic metres × 1.02264 × 39.5 ÷ 3.6. Electricity meter units were treated as electricity kWh. Estimated costs used electricity 0.2467 £/kWh, gas 0.0574 £/kWh, electricity standing charge 0.5721 £/day, and gas standing charge 0.2909 £/day.
