Oil to Gas Conversion Cost Northern Ireland

Most homes in Northern Ireland use home heating oil but the availability of natural gas has been increasing over recent years. More homes can now convert to natural gas than ever before.

Use our ‘Oil to Gas’ calculator to compare the cost to heat your home with gas compared to oil. You can also check whether gas is available where you live, consider the benefits of gas, how to convert and any help available with the cost.


Can my home connect to Natural Gas?

This is the key question! Many people are unsure if gas is even available where they live. The natural gas network in Northern Ireland is divided into three network areas. In each of the areas highlighted on the map there is a dedicated network operator responsible for the infrastructure that brings natural gas to your home

Ready to Switch to Gas…
If gas is available and you want to switch we can help. The first step is to arrange a visit from an energy advisor from the gas network operator (as it depends what gas network you live in). They will explain the benefits, the connection process and costs involved so you can decide if you wish to proceed. Remember the visit is free and you are under no obligation to change to gas.

To arrange a visit you can leave your details with Power to Switch – we will double check gas is available to your home and determine which gas network you live in. We will send your details to the relevant gas network company who will be in touch to arrange a home visit. Feel free to contact us at to ask any questions or check up on your application.
