A guarantee or alternative form of security given in respect of any liability of the undertaker to pay compensation under the Order is to be treated as enforceable against the guarantor by any person to whom such compensation is payable and must be in such form as to be capable of enforcement by such a person.

The guarantee or alternative form of security is to be in place for a maximum of 20 years from the date on which the relevant power is exercised.
