Business customer FAQ
Connecting to gas
What do I need to do to get a natural gas connection?
For commercial enquiries please contact Gas Networks Ireland on 1800 411 511 or call 1800 464 464 for domestic enquiries. Alternatively please click on one of the links below and these will help you through the connection process.
How long will it take to get a natural gas connection?
There are a number of factors that will determine the timelines for connection, for example the type of connection required, where the nearest gas pipe is located, nearby trees, rivers, railways, walls etc and local council Road Opening License timeframes and conditions. Usually commercial connections timeframes (from enquiry to connection) can range from 6 weeks to 14 weeks, depending on the connection complexity. A Gas Networks Ireland representative will be able to advise you on a more accurate timeline once they have visited your business.
How much would it cost to get the gas into my premises?
See link below for information in relation to Gas Networks Ireland connection costs:
To proceed with a connection enquiry, please fill out our Online Enquiry Form and one of our Businesslink team will be in touch with you, or contact our Businesslink team on 1800 411 511.
Can I pay for my connection through a monthly instalment?
Is there gas in my area?
You can find out if gas is available in your general area by connecting online. You can also email us a map of your property location to: email@example.com. For more detailed information please fill out our Online enquiry form and one of our businesslink team will be in touch with you. Or you can contact our Businesslink Team on 1800 411 511.
Can I add new gas appliances to my property?
I've just taken over a building which has a gas connection and wish to use the gas.
Is there a lot of disruption involved in getting a connection? Will my business suffer?
Once you have made an enquiry, a member of our dedicated gas connections team will visit your site to carry out a survey. They will be able to best advice on the connections process/timelines. Gas Networks Ireland endeavour to work with customers and to minimise disruption. Usually, we do not impact on day to day business operations as we around customers and there operating hours. This can be clarified during our site survey.
Do I need a Registered Gas Installer (RGI) to change over my equipment and install new natural gas pipework?
What is a Road Opening Licence and how long does this take to get?
A road opening license is legal permission given by the local council for public roads, green areas and footpaths to be excavated. Each local council has their own timelines and conditions. Gas Networks Ireland has agreements in place with all councils where there is gas located and therefore has foresight into existing timelines and conditions.
How do I submit a meter reading?
Where can my meter be located for my business?
Can I get another meter in my property?
Yes. We can arrange for a member of our sales team to meet you and discuss the options available to you if you want to install a new meter. You have the option to split an existing supply or add a second supply. Please contact us on 1800 411 511 or fill out our Online enquiry form.
Can you provide a downstream billing meter?
No. We will not install a billing meter downstream to bill another customer it will require another service. However, you can purchase a check meter these are available at various outlets nationwide.
Your installer can come to an arrangement with you to pay for a check meter and install it downstream of our meter (this arrangement will not invoice Gas Networks Ireland either in supplying or installing the meter)
Where can I get Hockey Sticks for my gas installation?
What are slam shut valves?
You will have to contract an RGI or Mechanical engineer to install slam shut valves, as they are downstream of the meter. We currently only fit slam shut valves on larger skid units, before installation. Slam shut valves are gas detection units that will shut the meter off if there is too much methane detected in the air around it.
What is a building management system?
A BMS or building management system is a system that provides a facility or company with visibility of their energy use.
You can find more information in our BMS brochure.
What is a volume corrector?
A volume corrector (VC) provides customers with a corrected meter read and is required when the annual quantity of gas used exceeds 3GWh. The volume corrector receives the reading from the meter and calculates a corrected reading, adjusting for the variations in the pressure and temperature.
You can find more information in our Metering and Volume Correction Information Pack.
Switching from oil to gas
Can my oil boiler be converted to natural gas by switching out the burner?
What difference will it make if I switch from oil to natural gas?
There are several benefits in switching to natural gas. See links below to find out more.
Can my current LPG equipment and pipework be used for the natural gas supply or do I need to change theses?
SPC, EAC and Non-Domestic Declaration of Conformance Certificate
How can I calculate my Estimated Annual Consumption (EAC) and my Maximum Hourly Load (MHL) to give to Gas Networks Ireland?
If you are already using another fuel for your business, you should check your bills over the last 12 months to get a view on how much fuel was used in a year. If nothing in your business is changing, then this figure can be used as your estimated annual consumption (converted into kWh). For the Maximum Hourly Load (MHL), it is recommended that you ask your chosen Registered Gas Installer (RGI) or Competent Installer/plumber as they will be able to offer technical information relating to the expected hourly usage of your equipment. Our technical representative can also review your usage and offer advice to confirm.
What is SPC?
SPC stands for Supply Point Capacity. For Small and Medium Business users, Gas Networks Ireland will calculate the SPC for new connections based on your Estimated Annual Consumption (EAC), measured in kWh. Your gas supplier is required to reserve space in the natural gas network to guarantee a secure supply of gas. The amount of space reserved by your gas supplier is referred to as the Supply Point Capacity. Gas Networks Ireland charge all natural gas suppliers for reserving this space. Your gas supplier then passes this charge onto you in the form of standing charges.
Where can I get a Non-Domestic Declaration of Conformance Certificate?
Do I need to submit a Non-Domestic Declaration of Compliance Certificate when I carry out a service to an appliance or add an appliance to a commercial building?
Who should I contact if I have a query about my bill?
For enquiries on your gas bill please contact your natural gas supplier. A full list of licensed natural gas suppliers is available from the CRU website.
Why can’t my installer turn on the gas after an escape once he has made repairs?
Gas Networks Ireland engineers and fitters are the only personnel authorised to restore gas to an IC premise. If your gas supply has been safety locked, your installer must complete a Non-Domestic Declaration of Conformance Certificate. This must be on site when we call to restore gas. Certificates can be requested by contacting our Businesslink Team on 1800 411 511.
Can you explain the conversion factor?
A natural gas meter measures the amount of gas consumed by all the gas appliances in a premise. The gas used is measured in cubic meters or cubic feet. However, your gas supplier must bill you on the basis of energy used i.e. kilowatt hours (kWhs). For domestic gas usage a conversion formula is used to convert cubic meters or cubic feet into kWhs. This conversion formula has been approved by the Commission for Regulation of Utilities. The conversion formula can vary nationwide. The formula depends on the local temperature, pressure and calorific value of the gas.
Factor used to convert the usage calculated between an opening and closing meter read from cubic meters (if metric meter) to kilowatt hours - components of the factor allow for pressure, temperature, compressibility and Calorific Value (CV).
Calorific Value is a factor used to calculate the energy equivalent of gas usage (The ratio of energy to volume measured in mega joules per cubic meter (MJ/m). Natural Gas is now obtained from multiple sources, so the CV changes on a daily basis and is calculated on the average daily usage over a billing period.
The method of calculating CV rests with Gas Networks Ireland, is in line with best international practice and has been approved by the CRU. CV is the amount of heat released when a mass of fuel (e.g. Natural Gas) is burned.
Please do not hesitate to contact your gas supplier should you require any further assistance regarding this matter.
What does change of sector mean?
For information on change of sector please contact your gas supplier. Contact 1800 411 511 to arrange an appointment.
**Please note if you have made any changes to your load our sales representative will need to call to site to establish possible new meter size and new EAC & SPC figures. Charges may apply**
