‘The great floods of colour and the bright tonality continue Turner's own fantastic ceremonies of light, but in Creffield's paintings [of Petworth] there is always the sense of the house and its land as organic, breathing forms’

— Peter Ackroyd CBE, biographer, novelist and critic, 1993

Abandoned for twenty years the buildings on [Orford] Ness seem as if they belong to a different world [...] Such a remarkable landscape requires a remarkable artist to understand and interpret it: Dennis Creffield is such an artist’

— Jeremy Musson, architectural historian, 1995
