Gas Switching FAQs

Domestic consumers in the Greater Belfast and Larne area (Phoenix Network) can choose from two suppliers: firmus energy and SSE Airtricity. Power to Switch can quickly and easily find the best deal for you and help you switch.

In the Ten Towns area (FIrmus Network) domestic customers can only be supplied by firmus energy. Other companies are now allowed to enter the market and provide choice – but as yet none have entered the domestic market. We will keep an eye on this and update our site when new suppliers and deals become available.

The West Network (SGN Distribution area) is bringing gas to areas including Coalisland, Cookstown, Dungannon, Magherafelt, Omagh, Enniskillen, Strabane and Derrylin. At the moment domestic customers can only have a gas supply from SSE Airtricity but other suppliers are able to enter this market

All you need is a few details: who your current gas supplier is, your current payment method and tariff. To get the most accurate comparison it’s best to use details of your current energy usage (or spend). This information will be included on your energy bill or statement.

If you don’t have details on your current usage or spend to hand you can use the average consumption figure which is 9,000kWh (Low), 13,500kWh (Medium) and 19,000kWh (High) for gas.

When it comes to comparing deals, you will need to know who your current gas supplier is. The easiest way to find this information is to check a recent gas bill.

If you don’t know who supplies your gas and can’t find a recent bill you can contact the relevant gas network operator.

Each gas supplier provides a choice of tariffs -– so it’s about picking the tariff that is best for you and your lifestyle. View our guide to tariffs here.

Price and savings will always rank highly when it comes to considering a new gas deal. But there are a few other things to consider….

Firstly, how you pay impacts on how much you pay! Payment options include Direct Debit, Pay as You Go, cash/card or cheque. And it’s worth remembering the best deals are usually available to Direct Debit customers.

How you are billed is also important. As with Direct Debit the best deals are usually available with tariffs that have online or e-billing rather than postal bills.

And a few other things to think about include…

  • What type of plan suits your needs best – a discount tariff, fixed price or Pay as You Go.
  • Is there a contract term with any offer, usually 1 or 2 years? Is there an early exit fee?
  • Do you want a gas tariff where the supplier offsets the CO2 footprint of your gas consumption?
  • Does the supplier offer any additional services e.g. Online account or smart technology?

Are there any other perks, cashbacks or promotions with the offer?


When you switch there are no changes to your meter or your pipework. If you change your mind you can cancel the switch up to ten working days after registering. The switch should be completed within 15 working days after the end of the cooling off period.

This really depends on you…and sometimes the best deal and cheapest deals will be the same and sometimes they won’t. Every household will be different – and it depends on what you value in terms of an energy deal. Maybe it’s the cheapest price, a deal with a cashback offer, or a fixed price deal.

It’s really about finding the deal that is right for you.

With ‘Power to Switch’ we can help you through this. We give you control over how to view results – you can view by price, by payment method or include the value of any cashback offer.

We also provide Information about each supplier, key features of the plan, payment and billing methods so any decision is made on full information.
