3 quick wins
- Have a recent bill or annual statement to hand so quotes use your real consumption.
- Compare unit rate, standing charge, payment method and exit fees together, not just one line.
- Take meter readings on the day your new supplier takes over.
What you need before comparing
- Know your annual kWh use for gas and electricity separately; your annual statement or supplier account shows it.
- Record your region, payment method (Direct Debit, prepayment or pay on receipt) and current tariff name and end date.
- Check whether you are in debt to your current supplier or on a prepayment meter: both can limit your switching options, so ask the supplier first.
How the switch actually runs
- Ofgem explains that the new supplier manages the whole switch; you do not need to negotiate with the old one or arrange an engineer visit.
- Your gas and electricity supply is not interrupted during a switch. The physical pipes, wires and meter stay exactly as they are.
- Your old supplier sends a final bill within six weeks of taking over the account. Check it against your meter readings and query anything wrong quickly.
Fixed, variable and the price cap
- A standard variable tariff tracks the Ofgem price cap, which changes periodically and is a limit on unit rates and standing charges, not a cap on your total bill.
- Fixed deals lock unit rates for the term. Compare a fix against your current rate using your own consumption, and check exit fees before signing.
- A price-cap figure quoted in the news is a typical-household illustration. Your bill depends on your own usage, region and meter type.
Avoid the common switching traps
- Check exit fees and any remaining minimum term before moving; rolling off a fix onto the standard variable tariff is usually the most expensive outcome.
- Ignore cashback and gifts until the underlying tariff is competitive. Rewards often have conditions and redemption deadlines.
- Keep confirmation emails, take final meter readings, and check the first new bill carefully against the deal you signed up for.
Mistakes to avoid
- Assuming switching interrupts your supply; it does not.
- Comparing tariffs on unit rate alone while ignoring standing charges and exit fees.
- Fixing for a long term without checking what happens if prices fall.
