How to use this supplier list

Each entry shows the fuels a supplier sells to homes, where it supplies and whether it was taking new customers when we checked. Suppliers change what they offer often, so always confirm on the supplier’s own website before you switch.

To compare prices, use our gas and electricity tariff comparison. It shows Ofgem’s price cap for your region next to fixed tariffs we have checked.

Great Britain and Northern Ireland are separate markets

Suppliers in England, Scotland and Wales are licensed by Ofgem, and most standard variable tariffs are covered by the Ofgem price cap. Northern Ireland has its own suppliers, regulated by the Utility Regulator, and its mains gas suppliers differ by gas network area. Northern Ireland homes aren’t covered by the Ofgem price cap.

How we check suppliers

For Great Britain we match each brand to its licensed company on Ofgem’s electricity licence list and gas licence list, then check the brand’s own website for a household offering. For Northern Ireland we use the Consumer Council’s tariff tables and each supplier’s website.

We leave out business-only suppliers and network companies. Where we couldn’t confirm a detail, we say so — “Check with supplier” means its website didn’t make clear whether it is taking new customers.

Names we checked and didn’t list: Unify Energy (business customers only); Pozitive Energy (business customers only); Love Energy (a broker, not a supplier); Electroverse (electric vehicle charging, not home energy); Rebel Energy (stopped trading); Tomato Energy (stopped trading); Igloo Energy (stopped trading); Tonik Energy (stopped trading); Electric Ireland (no longer supplies Northern Ireland homes); Energia (no household offer found in Northern Ireland); Flogas NI (sells LPG rather than mains gas).

Energy supplier FAQs

Can I choose any supplier on this list?

Not always. Some suppliers only serve certain regions or gas network areas, and some aren’t taking new customers. Visit the supplier’s website and enter your postcode to check whether it can supply your address.

Why isn’t every licensed supplier listed?

A supply licence on its own doesn’t prove a company sells to households today. We only list a brand once we have checked its own website shows a household offering, and we add smaller suppliers as we check them.

What happens if my supplier goes bust?

In Great Britain, Ofgem moves customers to a new supplier and your credit balance is protected, so your supply carries on. Don’t switch while that happens — wait until the new supplier contacts you.

Does the price cap apply in Northern Ireland?

No. Ofgem’s price cap covers England, Scotland and Wales only. Northern Ireland has its own suppliers and regulator, so its suppliers are listed separately here and aren’t part of our price cap comparison.

Why don’t directory entries show prices?

Prices depend on your region, meter and payment method, so we only show tariffs we have checked on the supplier’s own site. Those are in our tariff comparison; directory entries stay out of price rankings until their rates and eligibility are verified.
