I have a question about getting a retention permission/ regularisation certificate for an existing creche ( I'm an architect). The creche occupies a former dwelling but has been operating as a creche since the mid 90's. The clients are only renting the development and if at all possible they don't want to have to pay for a retention application to the Council. As the building has been used as a creche for over 5 years I'm pretty certain that no enforcement action can be taken against them if they don't get retention (I stand to be corrected). I have, however, advised them for the need to get a regularisation certficate and possibly a Disability Access Certificate (depending on any changes advised by the Fire Officer). Essentially I want to know does anyone know if there will be an issue with the regularisation application if there isn't any planning reference number to go with it? Does anyone know of any other issues that may come to the surface if retention is not sought by my client? I have been talking to a planner who is due to meet the Fire Officer in the next few days and he is to get back to me on it but was just interested to hear other people's opinions. Thanks in advance.
