f you mean “is the £15000 what person actually takes home after tax NI and pension?” — answer is no. Right now we’ve just calculated based on total budget have available. In UK when hire someone set aside has to cover: 1. Gross pay (what advertise) 2. Employer’s National Insurance (13.8% above NI threshold) 3. Employer pension contributions (at least 3% of qualifying earnings unless exempt) This means gross salary can advertise will be less than once those costs are taken into account.
