Frequently asked questions
Why might my real bill differ from this estimate?
Many utility providers use tiered/slab pricing (different rates for different usage bands) rather than one flat rate, plus separate taxes or surcharges not included here.
How is the fixed meter charge worked out?
It's applied automatically based on the gas company you select — you don't need to enter it yourself, just pick SNGPL or SSGC and it's included in the total.
Why does the rate change depending on how much gas I use?
This is slab/tiered billing — the first block of units is charged at one rate, the next block at a higher rate, and so on, similar to income tax brackets.
Does this include GST?
Yes, the breakdown shows GST calculated on the gas charges separately, alongside the fixed meter charge, so you can see exactly how the total is built up.
