The code was delayed due to a supposed MRO loophole last month, and was originally due to come into force on May 26.
But ‘drafting errors’ forced Government to delay, much to the frustration of tenants and campaigners.
Pubs code adjudicator Paul Newby told the PMA he had concerns about tenants’ knowledge of the code.
He said: “The code is coming in to introduce rights and protections and it’s important that tenants know about it.
“The pub companies are well organised, and so they should be they have the resources and time, but I have a big concern that there are a significant number of tenants whose awareness of what the code means for them is not great.
“Tenants need to know what might help them, and the things the code will and won’t do.”
Licensees have already missed out on their right to the market rent only option, and the British Pub Confederation estimated 220 tenants would miss out for every month the code is delayed.
