I have always heard that generally the opposite is true, dual fuel
cheaper from one single supplier.

I think it depends on usage. Dual fuel discount is usually £20-30. If
you're a low user, that makes sense. If you use a reasonable amount, the
difference in unit costs outweighs that. Given typical bills can be ~£1Kpa
it doesn't take a huge difference in unit cost to outweigh that £30.

It also requires that you have mains gas available!

I think you could usually do better with a dual fuel deal chosen to
maximise savings on the most heavily used fuel provided that you heat
your home in winter. If not then all bets are off.

An odd one is our VH gets its electricity from British Gas - in some
strange quirk of fate they came out the cheapest for electricity only!
