How a business in Windsor and Maidenhead compares prices
- Find your contract end date. It decides when you can switch and when suppliers will quote. The renewal planner works back from it.
- Get your meter numbers. Your MPAN for electricity or MPRN for gas identifies your exact supply, including which network region you are charged for.
- Work out your all-in price. Unit rate plus standing charge, with the cost calculator, so you can compare like with like.
- Compare on one day. Wholesale prices move daily, so quotes gathered weeks apart are not comparable. See which way the market has moved.
- Check the terms, not just the rate. Contract length, exit fees and any broker commission, which is shown in the contract's principal terms before you agree.
If you are already out of contract, you can usually move at any time without a fee. See out-of-contract rates and deemed contracts.
