25. Succession to a business, etc
(1) This Regulation applies where there has been a change of employer from whom an employee receives relevant emoluments in respect of his or her employment in any trade, business, concern or undertaking, or in connection with any property, or from whom an employee receives any annuity or pension.
(2) Where this Regulation applies, the change shall not be treated as a cessation of employment for the purposes of these Regulations, but, in relation to any matter arising after the change, the employer after the change shall be liable to do anything that the employer before the change would have been liable to do under these Regulations if the change had not taken place.
(3) The employer after the change shall not be liable for the payment of any USC that was deductible from relevant emoluments paid to the employee before the change took place.
