This has no impact in April 2024 as the levels and triggers remain frozen. Employers also have the option to use the tax period as the Pay Reference Period (PRP).

                                                                            Further consultation will occur on the reducing of the Pension AE age and threshold for a future implementation point.

                                                                                    The UK government announced changes as part of the Autumn Statement 2023 announcements confirming the approval of the Low Pay Commission recommendation for the uplifting of minimum pay rates within the United Kingdom – when they do the new minimum rates apply for pay periods commencing on or after 1st April 2024. 

                                                                                      Table 19

                                                                                      National Minimum pay is not about the employee hourly pay rate, but about the hourly rate received after any relevant reductions, and deductions for the benefit of the employer. Important factors are the accurate recording of working time as defined by NMW law and the treatment of certain working expenses, such as ‘uniform’. Timing of work and payment is also critical. Some amounts of pay do not count towards NMW pay such as the premium element of overtime. Absence is not counted as working time. It is possible for employees with hourly pay rates above perceived minimums are actually paid below National Minimum Wage.

                                                                                      These increases may result in lower paid employees no longer being able to participate in salary sacrifice or salary exchange arrangements where there is not sufficient excess pay to exchange. 

                                                                                        Living Wage and London Living Wage (Living Wage Foundation)

                                                                                        The real Living Wage is the only UK wage rate that is voluntarily paid by 9,000 UK businesses who believe their staff deserve a wage which meets every-day needs - like the weekly shop, or a surprise trip to the dentist.

                                                                                        The Living Wage is historically announced annually in November by the Living Wage Foundation, A Citizens UK initiative. In 2023, the announcement was made on 24th October 2023.

                                                                                          table 20

This time the announcement has been made prior to the start of the Living Wage week (6-13th November 2023), however, the deadline for an accredited employer is to implement the rates by 6th May 2024.

                                                                                            It is still possible for an employer who pays the Living Wage to be in breach of the government National Minimum Wage laws as the basis of qualifying and payment are different. Living Wage is about the rate of pay paid, whereas the National Minimum Wage and National Living Wage are about the pay received across the amount of time worked.
