Electricity and gas referral deals

Switching to a new energy plan, or know someone who is? Some energy providers offer referral deals that can help you both save money.

How do I choose the best energy sign-up offer?

Here's a quick look at the different types of offers you'll come across and what they actually mean.

1. Bill credit. This is the simplest one. You get a set amount, like $200, taken off your bill, either your first one or after you stick with the energy provider for a certain number of months. As long as you meet the conditions, you'll see the amount knocked off your bill.
2. Guaranteed discount. Instead of a one-off bonus, you get an ongoing discount on your usage and/or supply charges for a set benefit period, often 12 months.
3. Conditional discount. This only applies if you meet certain conditions, usually paying your bill on time or setting up direct debit.
4. Rewards points. Some providers offer Everyday Rewards or Qantas Points instead of a bill credit. That can be worthwhile if you're already collecting points, but it's not always easy to compare with cash as the value depends on how you redeem them.
5. Dual-fuel or bundling bonus. Some providers will throw in an extra credit if you sign up for both electricity and gas, or bundle another service, like internet. However, it's still worth comparing plans separately. You might find it's cheaper to go with different providers rather than bundle everything together.

What should I look out for before signing up?

A sign-up offer is always exciting, but you also need to check other things.

• A $200 credit isn't much of a win if you're paying usage and supply charges every month. Over a year, a plan with better rates can easily save you more than a one-off bonus, unless you're someone who regularly switches providers to chase the next deal.
• It's also worth checking when you'll actually get the credit. Some providers apply it to your first bill, while others make you wait a few months. If you move house or switch plans before then, you could miss out altogether.
• Keep an eye on any conditional discounts too. "Pay on time" sounds straightforward, but missing just one payment could mean losing the discount. Make sure you know exactly what's required.
• Don't skip the fine print either. Most sign-up bonuses are only for new customers, plus the offer can vary depending on which state you live in. The credit advertised elsewhere might not be available where you are.

Frequently asked questions

• How do I claim an energy sign-up deal?

  In most cases, you don't need to do anything beyond signing up for the offer.

  Once you're on the plan, the credit or discount is usually applied automatically to your bill, or bonus points are added to your rewards account.

  If it's a conditional discount, such as one for paying on time, you'll need to make sure you meet the requirements each month to keep getting the benefit.

• How long does it take to switch energy providers and will my power go off?

  Your power won't go off when you switch energy providers. The change happens behind the scenes, so your electricity or gas keeps running as normal.

  The switch usually takes a few business days to process, although the exact timing can vary.

  You'll receive a final bill from your old provider, then your new provider will take over billing.

• Can existing customers get these sign-up bonuses?

  Usually not. Most offers are for new customers only.

  If you're already with a provider, it's worth calling to ask what they can do to keep you, or comparing what you'd get by switching to a new provider entirely.

• Can I get a sign-up deal if I'm renting?

  Yes, you can. As long as the electricity or gas account is in your name and you're responsible for the bill, you can switch and claim a sign-up offer like any other customer.

• What happens to my deal if I move house?

  Moving usually means opening a new account at your new address, which can reset or cancel a bonus you haven't received yet.

  If you're mid-way through an offer and planning a move, check whether the credit carries over or whether it's worth timing your switch so the bonus lands first.
