Questions about switching
- How do I become a First Utility customer?
Simply register online. The registration process is simple and should take less than 10 minutes.
- I am a vulnerable customer, what services can you offer?
We have a selection of free services for our vulnerable customers. Click here to find out more.
- Do you perform a credit check?
Yes, we use the information that you have given us to make checks with our credit checking agency. If you are rejected due to a credit score this will leave a trace on your credit history.
- Are there any reasons why I can't switch to First Utility?
Yes, on rare occasions we are unable to take over your energy supply. This may be down to one of the following reasons:
- If you have a large gas point meter then, unfortunately you cannot switch to First Utility. A large gas point meter is a meter which consumes more than 73,200kWh in a footprint year. First Utility do not yet accept registrations consuming more than 73,200kWh. It's worth remembering that very few households are a large supply point in the UK.
- Your gas service is on an IGT (Independent Gas Transporter) network.
- You have an economy 7 or economy 10 meter.
- Your current electricity and/or gas meters are prepayment.
- You don't pass our credit check process.
- You are already signed up to First Utility
- You have multiple or de-energized MPANS
- I have a pre-payment electricity/gas meter, can I sign up to First Utility?
No. Unfortunately we do not offer a pre-payment service on our tariffs at the moment. This may change in the future. If you would like us to let you know when this service becomes available email your name and address to prepay@first-utility.com.
- I live in a new-build home with a smart meter already installed, how do I sign up to your services?
Call our team on 0845 215 5000 to set up your First Utility electricity and gas.
- Are you competitive with the 'Big Six' energy providers?
Yes. We have an in-house team who regularly price-check the rates of the big six energy providers, adjusting our prices to ensure our tariffs remain competitive. Plus you can directly compare your current supplier prices to ours on our site so you can ensure that you are making a saving before deciding to switch.
- Can I join First Utility without having a smart meter installed?
Yes, with our iSave tariff, which offers cheap dual fuel without a smart meter.
- How do I get a smart meter?
Please visit our Smart as Standard tariff page to find out if you are eligible for a free smart meter and to sign up to our smart tariff.
- Do I need to contact my existing supplier?
No, we will do this for you, and ensure no loss of supply to your home during the transition period.
