Three arrangements to distinguish
Supplier-owned exchange cylinder: You pay for gas and may pay an agreement charge or deposit to use the supplier's bottle. On exchange, the empty bottle goes back to the same supplier or its network. The brand, size and exchange group matter.
Customer-owned refillable bottle: You own an approved bottle and use a service that can refill that type. Ask where refills are performed and whether inspection or retesting is due. A shop offering swaps may not refill your own cylinder.
Fixed household installation: Larger domestic cylinders or bulk tanks can involve delivery, service or equipment charges in addition to the gas. Ask who installs, connects and maintains the equipment.
Why the wording matters
In the UK, Calor explains that a first bottle comes with a Cylinder Refill Agreement, that its bottles remain Calor property, and that replacement without a new agreement depends on the exchange group. Its terms say that the agreement is not a rental agreement. Flogas has its own cylinder agreement. These examples show why the exact written terms are more useful than a generic “rental” price.
In Australia, Elgas describes an ongoing service charge associated with its home 45 kg cylinders. Suppliers can use different charging structures, so ask for the current schedule of charges for your address.
Ask these questions before ordering
- Who owns the cylinder, and what proof of agreement or receipt should you keep?
- What are the first order, refill or exchange, delivery and recurring charges?
- Can the bottle be returned, and under what conditions is any agreement charge refundable?
- Can you exchange your existing brand and size, or will a new arrangement be needed?
- Will the supplier deliver and connect it at your exact address, or is it collection only?
- Who checks the regulator and connection, and what happens if the bottle is damaged or out of test?
Find a supplier
Start with the gas bottle search. If you are in the UK, see the UK supplier directory; for Australia, see the Australian directory. HouseGas shows why a supplier appears in location results so you can distinguish a published service area from a nearby location.
