If an applicant does not comply with the agreement, the local planning authority may not be able to follow the agreed procedure. However, in many cases, there will be good reasons to try to remedy what happened and renegotiate the planning performance agreement, as the reason for a problem may not be the fault of one party and may come from unexpected problems. It is important that the agreement is flexible enough to deal with possible changes in circumstances. A ECA between the applicant and the local planning authority does not guarantee a building permit, but it certainly improves communication between developers and the council and significantly increases the chances of a positive conclusion. We highly recommend their use. Planning service agreements must be entered into in the sense of a “Memorandum of Understanding”.
