To calculate the cost using a UK gas price we would want to have assumed an efficiency in HHV. This is because UK gas prices are given on an HHV basis. Either convention can be used as long as all of our fuel consumptions, efficiencies and energy prices are given on the same basis. Consistency is crucial.

If your audience is global, perhaps consider adding a toggle to switch the efficiency calculation to HHV. Think of it like the °C/°F toggle on some sites and apps.
