Information written in planning approval informatives is not deemed a requirement, simply good practice. If written in a planning condition however, it would need to be complied with & if not you can report to the planning inforcement officer.
Not sure on your right of access, but can't see how this can be removed without your agreement?
Builders / developers will always try & push to get what they want - don't be afraid to challenge them & ask for evidence of what they are telling you.
Best of luck.
