What's cheaper? Gas or electricity?

As winter tightens its grip across South Africa, many households are weighing up the cost of staying warm and asking whether gas or electricity offers the cheaper heating solution.

The answer is not as straightforward as many consumers might think, with electricity not always emerging as the most affordable option.

Using current gas refill prices and residential electricity tariffs, a model of a typical three-bedroom South African home suggests gas can often cost less than electricity when used as the primary source of winter heating.

The comparison follows earlier analysis showing that a 9kg gas bottle costs roughly the same across much of South Africa, with refills averaging around R365 despite regional pricing differences.
