How Much Will I Use?


Check out how much LPG you might use

Ongoing charges for bottled gas include a cylinder rental fee plus the cost of each cylinder refill. Check out the table to see how many cylinders you could expect to use each year. You may also find our appliance calculator useful to see how much your new appliance will cost you to run. See our indication of how many bottles you might use each year.

As long as you have a place to safely install gas cylinders, we can deliver 45kg cylinders filled with Contact Rockgas LPG to your home or business. This is your own personal gas supply and doesn’t require connecting to a gas network. A registered gasfitter will then connect your cylinders to your appliances and make sure everything is safe. As soon as one cylinder is empty, your automatic regulator will switch to the second. When this happens, just let us know and we’ll replace the empty cylinder on the next delivery day in your area. That’s all there is too it. No interruptions. No fuss.
