The payslip is still standard UK maths: £35,919 a year after income tax and National Insurance, identical to the same salary in Manchester. The useful London lever at this level is the pension: every £100 sacrificed into a workplace scheme saves £20 of income tax and £8 of National Insurance, and those savings are the same nationwide, but in London they can be the difference between renting forever and building a deposit.
What a pay rise actually pays you

One thing London does not do is tax your payslip differently: income tax and National Insurance are UK-wide, and no borough adds a local levy on salaries. Council Tax and travel differ by postcode, but the £2,993.30 figure is the same in Barnet or Birmingham.
