IT Support / Systems Admin Salary in London
London is the UK's highest-paying region for most occupations, reflecting its concentration of headquarters, financial services and professional firms. The capital's salary premium typically ranges from 20-40% above the national median, though higher living costs — particularly housing — significantly offset this advantage.
London weighting and the higher cost of living should be factored into salary comparisons. Average rents are roughly double the national average.
