Regulation 5 Repayment of application fees
If the person who has applied for an examination for the purposes of an original application or a further application fulfils the requirement for repayment to an applicant set out in sub-paragraph (a) or (b) of paragraph (2) the application shall, unless another time therefor is arranged, be treated as one in respect of which no fee is payable and any sum previously paid in respect of that application shall be repaid to that person.
The requirement for repayment to an applicant is that he—
has before the time appointed for the examination given the Secretary of State three clear days notice (whether in writing or otherwise) at the place appointed for that examination that he does not propose to submit the vehicle for examination at that time; or
satisfies the Secretary of State that the vehicle cannot or, as the case may be, could not be submitted for examination at the time appointed because of exceptional circumstances occurring not more than five days before that time and of which the applicant gives notice to the Secretary of State (whether in writing or otherwise) within three days of the occurrence of those circumstances.
