Brighton and Hove is one.

Not quite - there's a "Standard Fare" of £2.20, a "Short Hop Fare" of
£1.50, a "CentreFare" (for travel in the centre of Brighton and Hove) of
£2.00, plus more expensive fares for journeys that travel outside
Brighton and Hove, and also for night buses.

So a 'flat-ish fare' system rather than a strict flat fare.
