Who do I contact to find out when my bottles will be delivered?

Our customer care team unfortunately are unable to give you information about a specific delivery day. We are working on improving this process. Over Winter, please allow additional time for delivery.
Why did this bottle not last as long as my last delivered bottle? During temperature drops, when you’re utilizing several LPG appliances simultaneously or your primary bottle has lower pressure for your requirements, your regulator might switch over to the reserve bottle temporarily. This ensures a consistent flow of LPG, but it also means that your reserve bottle will be partially depleted before the regulator indicates red on the main bottle.

Do I need to be home for my delivery?

You will not need to be home for delivery. Any dogs that live on the property will need to be kept inside or behind a suitable fence separate to the area the bottles are kept. Please ensure we have access through any locked gates prior to delivery.

Who should I contact if I am moving house?

Please let us know as soon as possible if you are moving house. Our customer care team can organise moving your LPG to a new address or closing your account if you no longer require supply. Please email and allow up to 4 days for a response.

How to tell if a 45kg bottle is empty or how much gas is left in my LPG Cylinder?

The LPG will be cold inside the cylinder, so you can gently pour some hot (but not boiling) water down the side of the cylinder, then slowly run your hand down the side of cylinder where you have poured the hot water. When you start to feel the cold against your hand, this is where your gas level is currently.

How long does a 45kg last?

A 45kg gas cylinder could last more than a year if the LPG is only used for cooking. If LPG is used for cooking and hot water for a family of four, a 45kg cylinder could last approximately between 4-6 weeks (these are estimates as the length of showers, hot/cold water ratio and outside temperatures can all have an impact on your personal gas consumption).

Why is the LPG provider refusing to delivery 45kg bottles to my property?

All LPG providers must comply with mandatory health and safety obligations to protect their employees and customers. This means they may refuse to deliver gas bottles if your property has a long or steep driveway, stair access or any other obstacle that might pose a problem when delivering LPG. Some providers will only deliver if it can be done safely by one person. More information is available on our website under Bottle Delivery Information.
