There are two main benefits; price and convenience.
- Companies offering dual fuel packages will sometimes offer you an additional discount if you buy both gas and electricity from them. This can vary from being a fixed reduction in the overall bill to a special rate for one or other of the fuels you take.
- The benefit of convenience associated with dual fuel is that you only need to deal with one company should there be a bill query, complaint or when moving home. Certain suppliers will also offer the convenience of a single bill.
