Saddened, do you have the facts to back this up? It isn't at all clear. Planning Permission is required in this instance once the property experiences a change of use that affects its domestic classification. The key here is when it began operating under the classification of 'Childcare on Domestic Premises'. This is triggered under OFSTED's regulations once a carer employs 3 extra staff on any one 'shift'. I don't think there is anything in the public domain that confirms this occurred before planning permission was given.
