Standing charges – Fixes incurred annually no matter the water usage.
Any business can switch their water supplier when in their renewal period.
SPID stands for Service Supply Identification Number which is a 13-digit unique identifier that is included on your bill. This SPID is used as a reference address for your water services.

Your Water SPID will look like this “0000000000W0” and your sewage SPID will look like “0000000000S0A”. These can be found on your water bills.

We have created a simple four step guide to securing your new your water deal to make the process as simple as possible:
Step 1: Check your water consumption
Firstly, we need to know how much water you are using, and we can do this by figuring out your average water usage. You can find out your water usage by simply looking at your latest water bill and finding how much you are currently being charged for your water usage.
It is important to take note of the following figures from your business water bill:
- Your annual water consumption
- How much you’re currently paying on your water bill
- Details of the charges on your water bill
- Your Service Supply Identification Numbers (SPIDs)
- A recent water meter reading
Step 2: Understand your current water contract
Once you have all the information listed above, you need to understand the type of tariff you are currently on as there are many different tariffs out there. This information can also be found on your business water bill.
You should be able to find all the information you require about your business water contract on your water bills. On your water bill, you will also be able to find how much you are charges per cubic metre of water and the payments regarding your water and wastewater services.
If you have different suppliers for both clean water and wastewater we can help arrange a single contract for both.
Step 3: Your Quote
Once we have all your details on usage, we can then compare business water rates available currently within the water retail market. Your current tariff will be used as a benchmark against which you can compare other water prices on offer.
Step 4: Complete the deal
Once we have compared your new businesses water deal, we can go ahead and agree to the contract.
Your new supplier will only need to discuss:
- Your eligibility
- Give you full information about the tariff and the terms and conditions
- Answer any questions you may have
Once this process is complete, you will need to sign an LOA or letter of authority and we can secure your new water deal.
