Cost of Electricity Supply
across the UK

How much does electricity supply cost in the UK?

UK electricity supply costs typically range from £1,200 to £1,800 annually for average households. Prices vary significantly based on region, usage patterns, and supplier tariffs. Most standard variable rate tariffs cost between 24-28p per kilowatt-hour. Fixed-rate deals offer price certainty but often start higher. Business rates differ substantially from domestic pricing and depend on consumption volume.

What affects the cost of electricity supply in my area?

Electricity supply costs depend on five key factors: your regional distribution network operator (DNO), usage during peak versus off-peak hours, supplier's wholesale energy costs, standing charges, and contract type (fixed or variable). Seasonal demand, infrastructure maintenance costs, and government levies also influence pricing. Compare suppliers regularly as tariffs change quarterly.

What does an electricity supply service include?

Electricity supply services include energy delivery to your property, meter reading and billing, 24/7 customer support, and account management. Suppliers typically offer flexible payment options, usage monitoring tools, and online account access. Some include energy-saving advice, tariff switching assistance, and compensation schemes under Ofgem protection. Smart meter installation may be included.

What's the difference between a fixed and variable electricity tariff?

Fixed-rate electricity tariffs lock your unit rate and standing charge for a set period, typically 12-24 months, protecting against price rises. Variable tariffs fluctuate monthly with wholesale costs, offering lower initial rates but unpredictable bills. Fixed rates provide budgeting certainty but may end higher than variable rates during falling markets.

What should I check before switching electricity suppliers?

Verify the supplier is licensed by Ofgem and registered with Consumer Rights Act protections. Check their Trustpilot and Citizens Advice rankings for customer service ratings. Confirm contract end dates, exit fees, and early termination charges. Review standing charges, unit rates, and include all fees when comparing quotes. Ask about compensation schemes.

How long does it take to switch electricity suppliers?

Switching electricity suppliers typically takes 5-6 working days once you've submitted the switch request. Your old supplier must end supply within two working days of your new supplier activating service. You'll receive a final bill from your previous provider. Some suppliers offer faster switching; check confirmation letters for exact completion dates.

Do electricity suppliers need to be regulated and certified?

All UK electricity suppliers must hold an Ofgem generation and supply licence to legally provide energy. Ofgem regulates pricing standards, consumer protections, and meter accuracy requirements. Only licensed suppliers can serve domestic and business customers. Always verify a supplier's Ofgem registration before signing contracts. Unlicensed providers cannot legally supply electricity.
