Yes - many energy providers offer dual energy plans where you can purchase both electricity and gas from the same provider. This can often simplify the billing process, and may also result in discounts or special offers for bundling services.
It's also possible to link your solar electricity plan and your gas service, so the feed-in tariff you receive for your solar generation offsets the cost of your gas usage. It is important to compare the costs and benefits of dual energy plans from various providers to ensure you are getting the best gas plan and electricity plan for your energy needs.
