Will there be a 7 day Notice or a Regularisation Certificate in respect of the Disability Access Cer

There is no need for a 7 day notice in respect of a Disability Access Certifiate, as a Disability Access Certificate is not required prior to commencement - see above.

There is no need for a regularisation certificate as Disability Access Certificate only applies to works commencing from Jan 1 2010 and not retrospectively. A Disability Access Certificate must be acquired prior to opening, operating or occupying a building to which works required a Disability Access Certificate. A Disability Access Certificate can be applied for this purpose.
