Understanding Watts and kWh

Unit	Meaning	Formula
Watt (W)	Power draw at any moment	Given on appliance label
Kilowatt (kW)	1000 watts	Watts / 1000
Kilowatt-hour (kWh)	Energy used over time	kW x Hours
p/kWh	Cost per unit	Found on your bill

kWh is the unit your meter records and your supplier charges for.

Peak and Off-Peak Rates

Many UK households use Economy 7 or Economy 10 tariffs with separate day and night rates.

Tariff Type	Off-Peak Hours	Off-Peak Rate	Peak Rate
Economy 7	7 hours overnight	~8p/kWh	~25p/kWh
Economy 10	3 hours each of low, mid, high	~10p/kWh	~25p/kWh
Standard	None	Same rate all day	~24p/kWh

Shift high-draw activities like washing, drying, and heating to off-peak hours for savings.

Standing Charges

Standing charges cover the cost of maintaining the grid and your connection. They are billed in pence per day and add up quickly.

Provider Example	Standing Charge	Annual Cost
Low tariff	10p/day	36.50
Average tariff	25p/day	91.25
High tariff	45p/day	164.25

Fixed rates mean your usage habits affect only the unit-cost portion of your bill.

Rising Energy Costs 2026

Year	Avg Unit Rate	Avg Standing Charge
2021	15p/kWh	20p/day
2022	30p/kWh	35p/day
2023	27p/kWh	40p/day
2024	22p/kWh	35p/day
2025	23p/kWh	35p/day
2026	24p/kWh	35p/day

Rates fluctuate with wholesale prices, policy changes, and supplier competition. Always check your latest bill for accurate numbers.
