Jersey Electricity’s tariffs will increase by 2.5% from 1 March 2027, below the Island’s latest rate of inflation of 3%.
The increase will add just over £1 per week to the bill of a typical all-electric household using around 10,000 units of electricity annually.
The company said it had scheduled the increase for March to avoid the winter months, when electricity consumption is generally highest.
The announcement comes as Jersey Electricity continues its £120 million network investment programme, known as the Big Upgrade, which is intended to increase capacity and improve the resilience of the Island’s electricity infrastructure.
Chief Executive Chris Ambler (pictured) said: “We know that any increase in household costs is unwelcome, so we have worked hard to keep this rise below the Island’s current rate of inflation. We have again delayed the increase until March, which means it will not affect customers during the colder winter months when electricity consumption is generally at its highest.
“We are acutely aware of the pressures many Islanders continue to face. Our responsibility is to manage the business prudently, find efficiencies wherever we can and keep prices as affordable as possible for customers, while making the long-term investments needed to ensure Jersey continues to benefit from a safe, reliable and future-ready electricity network.”
According to independent benchmarking cited by Jersey Electricity, the proposed domestic tariff of 24.82p per kWh is approximately 17% below comparable UK prices and 3% below the European Union average.
The company purchases most of Jersey’s electricity from nuclear and hydroelectric sources in France, with local generation facilities providing additional capacity when required.
Jersey Electricity has also secured a new four-year electricity supply agreement with EDF, which will take effect on 1 January 2028. The agreement is intended to provide greater flexibility in electricity purchasing as demand patterns change.
Mr Ambler added: “The new EDF agreement gives us further confidence in the long-term security of Jersey’s electricity supply and greater flexibility in how we manage future energy requirements. As Jersey becomes increasingly reliant on electricity, making the best use of both the energy we purchase and the network that delivers it will become increasingly important.
“Together with the investment we are making in the Island’s infrastructure, this puts us in a strong position to manage that change while continuing to provide customers with a secure and competitively priced electricity supply.”
