Sorry, but just giving us the PCN numbers isn't much good to us. Please add the date of each PCN, and the date received. None of the statutory grounds for cancellation of your PCNs matches your circumstances, except
possibly 13 (3)(c) or (e) below: -
Extract from The Road User Charging (Enforcement and Adjudication) (London) Regulations 2001Representations against penalty charge notice
13.—(1) Where it appears to the recipient that one or other of the grounds mentioned in paragraph (3) are satisfied, he may make representations to that effect to the charging authority who served the penalty charge notice on him.
(2) The charging authority may disregard any such representations which are received by them after the end of the period of 28 days beginning with the date on which the penalty charge notice was served.
(3) The grounds are—
(a)that the recipient—
(i)never was the registered keeper in relation to the vehicle in question;
(ii)had ceased to be the person liable before the date on which the vehicle was used or kept on a road in a charging area; or
(iii)became the person liable after that date;
(b)that the charge payable for the use or keeping of the vehicle on a road on the occasion in question was paid at the time and in the manner required by the charging scheme;
(c)that in the circumstances of the case no penalty charge is payable;
(d)that the vehicle had been used or kept, or permitted to be used or kept, on a road by a person who was in control of the vehicle without the consent of the registered keeper;
(e)that the penalty charge exceeded the amount applicable in the circumstances of the case;
(f)that the recipient is a vehicle-hire firm and—
(i)the vehicle in question was at the material time hired from that firm under a hiring agreement; and
(ii)the person hiring it had signed a statement of liability acknowledging his liability in respect of any penalty charge notice imposed in relation to the vehicle during the currency of the hiring agreement.
Please wait for others to comment, but the main point is that you had an auto-pay account for payment of the charge, but due to the circumstances described, (describe the problem with you and your business partner), the account failed to be topped-up without your knowledge. The first you knew about the problem was when PCN <number> arrived, followed soon after by another <nn> ULEZ PCNs. Say that the total amount payable represents a disproportionate penalty for something you only realised had occurred when the first PCN arrived. You therefore request that they accept payment for the first PCN and cancel the remainder. ALso state that going forward from this point you cotinue to pay the ULEZ as and when required and have now topped-up your ULEZ account, (is this true ?)
