He won the Olivier for the last of these. The RNT production of Othello played an engagement in Brooklyn, New York in 1998. Ben Brantley, in The New York Times, wrote that Pyant's lighting for this production was "exquisite". Pyant's lighting design for the 2010 West End production of Waiting for Godot was called "lyrical". He has also designed lighting for productions of the Donmar Warehouse in London since its opening. For the Royal Shakespeare Company, he has lit productions of Richard III, The Tempest, The Painter of Dishonour and Julius Caesar.

Pyant commented on working on the two productions: "You know going into the project that these are two very different productions to light." For the Chichester Festival Theatre, he designed the lighting for productions in 2005, 2007 and 2008, including The Scarlet Letter and King Lear.
