An update to your electricity tariff

An update to your electricity tariff

From 1 March 2026, a 2.5% increase to electricity prices came into effect. This will be shown in the first electricity bill you receive after 1 March. 

We understand that any increase in household costs can feel challenging, and we want to assure you that we have kept this adjustment as low as possible. For a typical all-electric home using around 10,000 units of electricity a year, the change amounts to around £60 per year, or just over £1 per week*. 

We first announced this change in November 2025 and chose to delay the introduction until March 2026 so that it wouldn’t affect bills during the colder winter months. 

If you’re concerned about your energy costs or would simply like to chat through the support available, our Customer Care team is here to help. We can make sure you’re on the best tariff for your needs and heating system and offer practical advice on using energy more efficiently. 

 

 

*Consumption assumptions are based on a typical all-electric heating household in Jersey. Bill impacts are estimates and will vary depending on domestic usage patterns and meter type. 

For home Help New builds & renovations New electricity supply

To help us provide the correct size supply to your new property, we need certain information from you. Please follow this guide to ensure we deal with your enquiry as quickly as possible. It covers:

Step 1 - Complete an Electricity Supply Enquiry (ESE) form

To complete an Electricity Supply Enquiry (ESE) form for a new domestic property you will need to provide the following:

  • A site location plan
  • A ground floor drawing with all existing services and/or the proposed new services marked
  • All your proposed electrical load in kilowatts (kW)

The ESE should be completed by a person with a good knowledge of the property's required electrical loads. If you are not confident you can accurately work out the property's required electrical load, we recommend asking an experienced electrical contractor to complete the ESE form on your behalf.

The ESE form is an editable PDF. You can complete it using a computer, or print it and fill it out by hand.

Step 3 - We confirm receipt of your application

Once we've received your completed ESE form, we will send you written confirmation and begin processing your application.

Step 4 - We will arrange a site visit if necessary

Depending on the scale and complexity of the installation, we may need to arrange a site visit. We will contact you to arrange a suitable time for our Service Planning Engineers to visit the site.

Step 5 - We send a written quotation

After the site visit we aim to provide written quotation within the following timeframes:

  • 15 working days - if providing a standard supply or altering an existing supply.
  • 25 working days - if connecting your supply involves significant network reinforcement works.

Meter connection

When your supply works are complete and paid for, you need to get the supply connected to a meter. To do this, you need to complete the following forms:

We can't energise the supply from the meter unless a customer is signed up and has an account with us.

We'll always try and process your request within five clear working days of receiving it. We'll contact you if we need to arrange access.
