The Default Market Offer is set by the independent regulator and acts as a reference price, providing a ‘like for like comparison’ for energy consumers to easily compare market offers.
When browsing market offers you will see them compared against the Default Market Offer as a percent (i.e this offer is 10% lower than the Default Market Offer). This can provide peace of mind for energy consumers, as they have a benchmark when comparing different energy offers. For more on the Default Market Offer head here.
