Rental and Service Fees

What is the cylinder rental fee?

This fee is for the rental of gas cylinders. The price of the cylinder swap only pays for the gas itself. The cylinders themselves have a substantial dollar value (between $150-$200,000+ depending on the size of tank or cylinder we have provided). This fee covers periodic retesting, repair, maintenance, and new cylinder acquisition. This concept is similar to the standing charges levied by some Telephone, Electricity and natural gas companies.

We maintain ownership and responsibility and as such, are responsible for maintenance and compliance regulations. Damaged cylinders are normally replaced at no charge to customers.

Where does this maintenance and testing occur?

For swap and insitu cylinders smaller than 250kg, this occurs at our depot. Cylinders are purged before any formal testing. For larger tanks, purging and testing occurs on site. Note we cannot perform testing on swap cylinders that are not owned or managed by Black Cat Gas.


When was I informed about this fee?

If you are a brand new customer, it will be on your very first invoice. If you have taken over an account from someone else, it will be on the anniversary of their rental. If you set up an account online, you will have had to see the red warning when buying a cylinder noting that a subscription is required for purchase.


What happens if I have moved out?
After 21 days have passed from the due date, the cylinders automatically go out for collection, as we have assumed that the residents have moved from the premises.


Do all cylinders have a rental?

Yes, unless they are customer owned. Customer owned cylinders have different stamping on them and will have testing certificates.


Are cylinders able to be bought?

Some types cylinders and tanks are able to be purchased, but we are unable to deliver customer owned swap cylinders. Refill only (insitu) cylinders (90kg, 210kg) can be delivered upon request. Tanks are available to be delivered, installed, tested as a site allows. We currently offer a small 18kg (about double the size of a BBQ cylinder) cylinders for sale but must be picked up from in store.


Where is my subscription id for the rental fee?

On the invoice under source document, or you can find all your subscriptions under your customer portal.


Why do I have multiple subscriptions?

A customer can have multiple subscriptions under the following circumstances:

·         Multiple delivery sites

·         Multiple contract types

·         Added cylinders at different times of the year

Why don’t you include the cost of the cylinder with the gas?

Because everyone uses gas at a different rate.  This would require different pricing for every customer.

The cylinders are expensive. There are substantial requirements regarding ongoing inspections of cylinders before filling. The 45kg cylinder rental price has not changed in over twenty years, despite increases in cylinder costs since then.


Do you have direct debit or saved credit cards for cylinders and rentals?

This feature is currently being tested by some customers and is scheduled to become available in May 2021.

Do you accept American Express?

Its on the todo list.

Do you support Bpay?

This feature is currently being tested.


Cylinders and Tanks

Are gauges available for all cylinder types?

Gauges are available for 90kg and above only. Note that 90kg gauges are only show 0-40%, and 210kg gauges show only 0-80%. This is due to the width of the cylinder.

Gauges are not available for 45kg swap cylinders.

Is remote monitoring available?

Remote monitors are available for some types of cylinders (90kg, 210kg) and most tanks. It requires a R3D gauge type. Remote monitoring comes with additional fees and requires a decent 3G/4G signal.

Are you able to fill customer owned cylinders?

Yes, but for 45KG and under this must be brought to our depot and booked in advance. Larger cylinders may request a tanker refill as required. Cylinders must pass all quality control and legal requirements. Refill sites must pass all regulatory requirements and a safety inspection.


What is the difference between “insitu” cylinders, “swap” cylinders and tanks?

Insitu or refill cylinders are set in place and filled by tanker. These cylinders are typically more expensive than swap cylinders but allow for more gas to be stored.

Swap cylinders are literally swapped during each delivery and are the standard for domestic use.

Tanks are permanent in place installations for bulk filling.

See the size table below for more information.


What cylinder and tank sizes are available?

Note values are rounded. Cylinder dimensions and tare may vary between manufacturers.


Tank sizes vary from 0.5T to almost any size and are available per customer request. Install, transport, purging are also available.



Where can I find your delivery schedule?




What is the cutoff time for online deliveries?

Midnight unless otherwise specified.



What does it mean to be an “Independent LPG” supplier?

Since early 2020 we do not buy LPG or LPG cylinders through any major gas company; instead we are able to buy direct. This is unusual in our industry.


Are you able to provide other gases?

Not as an independent, we are a BOC agent and we can supply medical, industrial and hospitality gas through them.


Online Ordering and Portal

Do I need separate login details for blackcatgas.com  or tarrrantsgas.com?

No. Your login details and portal will work the same for either site.


Can Commercial customers order via the portal? Can I order sizes other than 45kg online?

Currently this is unavailable. Maybe in the future.
