Compare business gas suppliers
Six suppliers on our panel sell mains natural gas to businesses connected to the Gas Networks Ireland network. If your premises is not on the network, LPG suppliers deliver gas to a tank or in cylinders instead.
Mains natural gas
-
Bord Gáis Energy
Small to large firms, with unit-rate fixing.
-
Electric Ireland
Gas for SMEs, start-ups and large users.
-
Energia
Gas alone or with electricity, tailored quotes.
-
Flogas
Natural gas for SMEs and larger businesses.
-
SSE Airtricity
Natural gas and a certified green gas option.
-
Yuno Energy
Gas for small and medium-sized businesses.
LPG for premises off the gas network
LPG is delivered by tanker or in cylinders rather than piped, so it is bought on different terms from mains gas. See mains gas or LPG below.
-
Flogas
Bulk tank and cylinder LPG for businesses.
-
Tervas Gas
Bulk and cylinder LPG, not mains gas.

How business gas pricing works
A mains gas bill has fewer parts than an electricity bill, but the same rule applies: compare the charges the supplier controls, and treat the rest as fixed.
- Unit rate
- The price per kilowatt hour (kWh) of gas. Your meter measures volume, and the bill converts it to kWh using the energy content of the gas, so compare suppliers in cent per kWh.
- Standing charge
- A fixed charge for each day you have a gas supply. For a business that only uses gas for heating, it continues through the summer when usage is low.
- Network charges
- Gas Networks Ireland’s charges for carrying gas through the network, approved by the CRU. They are usually built into the supplier’s prices.
- Carbon tax
- A Government tax on natural gas, charged per unit used. It is the same whichever supplier you choose and is shown on your bill.
- VAT
- Charged on the bill and shown separately. VAT-registered businesses can generally reclaim VAT on gas used for the business.
Why gas usage is so seasonal
Gas use depends heavily on what you use it for, which changes how you should read a quote.
| Main use | Usage pattern | Watch most |
|---|---|---|
| Space heating | High in winter, low in summer | Standing charge |
| Cooking | Steady, follows trading hours | Unit rate |
| Hot water | Steady all year | Unit rate |
| Process heat | High and steady | Contract structure |
When you ask for quotes, give a full year of usage rather than one bill, so a winter or summer bill does not give a misleading picture.
Mains natural gas or LPG?
Both are called gas and both fuel cookers, boilers and heaters, but they are bought very differently. Which one you can use depends on whether the gas network reaches your premises. Gas Networks Ireland’s network serves more than 720,000 homes and businesses in 23 counties, so many rural premises rely on LPG.
Mains natural gas
Piped to your meter through the Gas Networks Ireland network.
- Supply: continuous through the pipe, no deliveries
- Metering: a gas meter identified by your GPRN
- Pricing: unit rate per kWh plus a standing charge
- Switching: a supplier change; same meter and pipes
LPG
Liquefied petroleum gas, delivered to a tank or in cylinders.
- Supply: tank refills or cylinder exchange
- Equipment: a tank or cylinders, often from the supplier
- Pricing: per delivery or unit, plus any tank rental
- Switching: depends on tank ownership and your agreement
Appliances are set up for one gas or the other, so a move between LPG and natural gas needs a registered gas installer to convert or replace them. If you are not sure which you have, a gas meter with a GPRN means mains gas; a tank or cylinders means LPG.
What is a GPRN?
Your Gas Point Registration Number (GPRN) identifies the gas connection at your premises. It is seven digits long and is linked to the property, not to you or to your gas supplier, so it stays the same when you switch.
The GPRN is printed on every mains gas bill, though where it appears depends on the supplier. If you have no bill, for example after moving into a premises, Gas Networks Ireland can give it to you once you confirm the address and meter details. LPG supplies do not have a GPRN.
What to have ready for a gas quote
- GPRN for each gas meter or site
- A year of bills, so seasonal use is clear
- What you use gas for: cooking, heating, hot water or processes
- Contract end date and notice period
- Planned changes, such as a new kitchen, longer hours or a heat pump
Business gas contracts, renewals and switching
Business gas contracts follow the same broad pattern as electricity, with a few points that matter more for gas.
Fixed price
A unit rate fixed for the term protects you from price rises over winter, when heating use peaks. Leaving early may cost an exit fee.
Variable price
The rate can change during the contract, with notice. It gives flexibility but less certainty over your biggest bills of the year.
Fixing for larger users
Some suppliers let medium and larger users fix their unit rate at set times, or fix part of their volume.
Contract length
Compare quotes over the same term. A contract that ends in late autumn leaves little time to compare before the heating season.
Renewal
If you do nothing at the end of a fixed term, many contracts move to standard rates, often higher than a new fixed price.
Switching
Your new supplier arranges the switch using your GPRN. Gas Networks Ireland keeps running the network, so the supply is not interrupted.
Common business uses for gas
-
Cafés and restaurants
Hobs, ovens, fryers and grills give instant heat. Usage follows covers, so busy and quiet seasons show on bills.
-
Hotels and pubs
Heating, hot water for rooms and a kitchen, often running from early morning to late at night.
-
Bakeries and kitchens
Ovens running long hours, often overnight. Steady, high usage makes the unit rate and term the main levers.
-
Heating and hot water
Gas boilers in offices, shops and surgeries. Usage peaks in winter, so standing charges matter in summer.
-
Higher-use sites
Laundries, leisure centres, nursing homes and manufacturers using gas for process heat or large boilers.
Questions to ask before you agree a gas contract
Ask each supplier the same questions, so the quotes can be compared fairly.
- What are the unit rate and standing charge?
- Ask whether they are quoted in cent per kWh and whether they include VAT and carbon tax.
- Is the price fixed through the winter?
- Check the start and end dates against your heating season, and which parts of the price are fixed.
- What happens when the contract ends?
- Ask which rate applies if you do not renew, and how much notice you must give to leave.
- Is there an exit fee?
- Find out the cost of leaving early, for example if you change premises or replace gas equipment.
- Is a deposit needed?
- New businesses may be asked for a security deposit. Ask how much and when it is returned.
- For LPG, who owns the tank?
- Ask about tank rental, minimum deliveries, servicing and what happens to the tank if you change supplier.
Business gas in Ireland
Gas Networks Ireland runs a network of 14,781 km of pipelines serving more than 720,000 customers in 23 counties, including about 28,500 industrial and commercial customers.
Gas customers switch supplier regularly. CRU figures show 13,994 gas switches in March 2026, counting household and business customers. Because the network stays the same, switching changes your supplier and your price, not your pipes or meter.

Business gas: frequently asked questions
How much does business gas cost in Ireland?
It depends on how much gas you use, what you use it for, the contract length and when you agree the price. Most suppliers quote businesses individually, so the best guide is a quote based on a full year of your usage. Request a callback to talk through the options.
Can I get mains gas at my premises?
Only if the Gas Networks Ireland network reaches your area and your premises is connected. If it is not connected, Gas Networks Ireland handles new connections, and you then choose a supplier. Off the network, LPG is the usual alternative.
Is LPG the same as natural gas?
No. Natural gas is piped through the network and metered, while LPG is delivered to a tank or in cylinders. Appliances are set up for one or the other, and the two are bought and switched differently. See mains gas or LPG.
Where do I find my GPRN?
On your gas bill. It is seven digits long and linked to your premises. If you do not have a bill, Gas Networks Ireland can give it to you. See what a GPRN is.
Will switching gas supplier interrupt my kitchen or heating?
No. Gas Networks Ireland operates the network whichever supplier you choose, so the change is in billing only. Give a meter reading on the switch date so your bills are accurate.
Should I get gas and electricity from one supplier?
It can be simpler, and some suppliers offer combined business plans, but each fuel is priced separately. Compare a combined offer with separate quotes. You can also compare business electricity suppliers.
