Comparison site's do not always show gas only prices, some show them but they are hidden and when it comes to advertising they just don't like to serve up gas only tariffs they always try to push duel fuel, Why! its simple they get paid for both fuels and do the same work.


Why is this important?  The answer to that is that it is often cheaper to buy gas and electricty from separate companies.


Its a good idea to compare fuel prices but your search should also include the suppliers sites to make sure you are getting the best prices.
