An END is an electronic message to Land Registry authorising the cancellation of the charge entries. It does not, of itself, cause the charge to be cancelled. It must be combined with a formal application to Land Registry to discharge the charge. When that application is received, Land Registry's staff cancel the entries relating to the charge being discharged.
An ED cancels the charge entries automatically and, in most cases, immediately. It does not require a separate formal paper application to discharge the charge. It also does not require manual intervention – it is a computer to computer, system driven process.
