Energy Supply on the Isle of Anglesey
Energy costs are a major concern for households and businesses across the Isle of Anglesey. Many properties are older, stone-built and exposed to coastal winds, which can increase heating demand. A significant share of rural homes are off the mains gas grid, relying on electricity, oil or LPG. Meanwhile, the island is home to a growing number of solar panels, heat pumps and electric vehicles, making smart and export tariffs increasingly relevant.
The UK retail energy market is regulated by Ofgem, and most suppliers operate nationally, so Anglesey customers can choose from the same range of providers as anyone in Great Britain. The key differences lie in tariffs, customer service, technology and green credentials. This guide reviews ten of the most notable suppliers.
How We Ranked These Suppliers
We considered customer satisfaction, tariff range including time-of-use and export options, renewable energy sourcing, smart meter support, help for vulnerable customers and suitability for homes with solar, batteries, heat pumps or electric vehicles.

Energy Trends on the Island
Smart meters are enabling time-of-use tariffs that reward shifting consumption to cheaper periods, which can benefit homes with storage heaters, heat pumps or EVs. Export payments have made solar more financially attractive. Welsh Government programmes support energy efficiency improvements for low-income households, while community energy projects such as those led by Menter Môn demonstrate local approaches to clean energy. Network investment by SP Energy Networks is also important as demand for electricity grows.
Frequently Asked Questions
Who is responsible for power cuts on Anglesey?
Power cuts are handled by the distribution network operator for North Wales, SP Energy Networks, rather than your supplier. You can contact them directly by calling the national 105 power cut number.
Is a smart meter worth getting?
A smart meter provides accurate bills without manual readings and unlocks time-of-use tariffs that can reduce costs, especially for homes with electric vehicles, heat pumps or batteries. Installation is free through your supplier.
What help is available for households struggling with energy bills?
Suppliers offer payment plans and hardship support, and the Priority Services Register provides extra help for vulnerable customers. Welsh Government schemes also fund energy efficiency improvements for eligible low-income households.
How to Choose an Energy Supplier
Start by checking your annual consumption on your bills, then compare tariffs using an accredited comparison service. Consider whether a fixed tariff provides useful certainty or whether a smart tariff could cut costs. If you have solar, check export rates carefully. Look at customer service ratings and support for vulnerable customers, including the Priority Services Register. Switching is usually simple and does not affect your supply, so it is worth reviewing your options regularly.
