Frequently Asked Questions
As Supplier?
The majority of gas suppliers are signed up to the Energy Switch Guarantee. Under the guarantee, it should take no longer than 5 working days to complete your switch. There will be no interruption to your energy supply and if you change your mind within 14 days, you can return to your old energy supplier.
Can I Switch if my Account is in Debit?
If your account is in debit or you still owe money to your old supplier you can still switch energy suppliers. However, you will receive a final bill from your old supplier which you will be required to pay in full.
Can I Install a Smart Meter?
Every household in the UK is entitled to request a smart meter. You should contact your supplier and they will let you know whether they can install a smart meter.
How Does the Energy Price Cap Work?
The energy price cap is a limit on the amount suppliers can charge homeowners for the energy they use. It is reviewed every 3 months by the energy regulator Ofgem.
The cap takes into account wholesale prices and the state of the current energy market. It’s worth bearing in mind that the cap is the maximum suppliers can charge so tariffs at the upper end of the cap will not always represent a good deal.
What is an MPRN?
MPRN stands for Meter Point Reference Number. This is the number which identifies your gas meter. This allows you to compare gas tariffs online and ensures you won’t be charged for somebody else’s energy usage.
You can usually find this number on your gas meter or a recent bill.
