Dear …
RE: __(Type of Contract)__
Regrettably, it has come to our attention that __(Name of Company)__ is not qualified to undertake the recently awarded __(type of project)__ project. The required __(type of licensing)__ licensing is not in place, which is a direct breach of contract. Therefore, __(Name of organization)__ has been left with no alternative but to immediately rescind the contract from __(Name of Company)__. Effective __(date)__, the project site is hereby closed to __(Name of company)__, including employees and sub trades thereof.
It was clearly stated throughout the tendering process, that companies bidding on this __(type of contract)__ project must be adequately licensed. This blatantly deceitful attempt to secure a contract without the appropriate licensing is a reprehensible act. And as a result, __(Name of company)__ will be barred from bidding on any future projects with __(Name of organization)__.
Yours truly,
