What Are Energy Bills?
Energy bills represent the costs of essential utilities that make your home comfortable and functional, primarily gas and electricity. These bills vary based on consumption, tariff type, and market conditions, making understanding and management crucial for household budgeting.
Your energy bills typically include standing charges (daily connection fees), unit rates (cost per kWh), government levies, and VAT. Additional services like smart meter installations, meter readings, and customer service are factored into overall pricing structures.

Before Moving Home: Essential Steps
Pre-Move Energy Checklist
Contact Current Suppliers (48+ Hours Before)
Notify your current gas and electricity suppliers of your moving date and new address. Provide at least 48 hours notice to ensure smooth transfer and final bill processing.
Arrange Final Meter Readings
Schedule final meter readings for your moving day or arrange for the supplier to visit. This ensures accurate final bills and prevents disputes over consumption charges.
Research New Property Suppliers
Identify who supplies your new property and check tariff options. This preparation enables quick setup and potential switching to better deals.
Settle Outstanding Balances
Clear any outstanding bills or credit balances with current suppliers. Request refunds for credit balances and arrange payment plans for outstanding amounts.
Moving Day Essential Actions
Moving day requires specific energy-related actions to ensure accurate billing transitions. Taking meter readings and notifying suppliers prevents billing errors and ensures you only pay for energy you actually consume.
