Construction minister Michael Fallon wrote to major public construction companies last November warning he would name and shame leading companies not signed up to the voluntary payment code.
The move saw a spate of sign-ups including Carillion and Laing O’Rourke prior to the list being made public.
Yesterday Costain’s name was added to the list of firm committed to paying their suppliers within clearly defined terms.
Major contracting names still to join include Galliford Try, BAM, Vinci, Wates and ISG.
Berkeley Group is the only stock market quoted volume house builder to sign up to the PPC.
