Understanding the London Median Salary and How Working Hours Affect Your Pay

When researching the London median salary, it is important to recognise that the most recent official data from the Office for National Statistics (ONS) Annual Survey of Hours and Earnings (ASHE) covers the UK as a whole. In April 2025, the median gross annual earnings for full-time employees stood at £39,039, with median weekly earnings of £766.60 and median hourly earnings (excluding overtime) of £19.67 per hour [ONS ASHE]. These figures provide a national benchmark, but they do not isolate London. The capital typically commands higher pay due to the higher cost of living, often reflected in London weighting or Higher Cost Area Supplements (HCAS). For example, NHS pay scales for 2026/27 include HCAS rates that add a premium to base hourly rates, such as a Band 1 starting rate of £12.92 compared to the National Living Wage of £12.21 [NHS Employers pay scales].

The Role of Hours Per Week Assumptions

Converting an hourly rate to an annual salary depends heavily on the number of contracted hours per week. The ONS defines full-time work as more than 30 paid hours per week (or 25 for teaching professions), while part-time is 30 hours or fewer. A common assumption for full-time roles, especially in the NHS and many public sector jobs, is 37.5 hours per week. Using this assumption, the conversion rule of thumb is:

Annual salary ≈ hourly rate × 37.5 hours × 52 weeks

For example, at the UK median hourly rate of £19.67, this gives approximately £38,400 per year, close to the ONS median annual figure. However, if you work 40 hours per week, the annual figure would be higher. Part-time workers should adjust the hours accordingly. Always check your contract for your exact contracted hours, as overtime, unpaid breaks, and salary sacrifice schemes can affect the actual annual amount.

Part-Time vs Full-Time: What the Data Shows

The ONS ASHE data reveals that part-time employees had median weekly earnings of £280.00 in April 2025, compared to £766.60 for full-time employees. This gap is partly explained by fewer hours, but also by differences in job roles and hourly rates. The share of part-time employee jobs increased to 28.0% in 2025, up from 27.2% in 2024, which can influence overall average pay growth [ONS ASHE]. When converting part-time hourly rates to an annual salary, use the same formula but with your actual weekly hours. For instance, a part-time worker earning the National Living Wage of £12.21 for 20 hours per week would earn approximately £12,698 per year (before tax and National Insurance).

London Weighting and NHS Pay Scales

While a precise London median salary figure is not available in the search results, the NHS pay scales for 2026/27 provide a clear example of how London weighting works. The Higher Cost Area Supplements (HCAS) add a percentage to basic pay, with a minimum payment of £5,794 and a maximum of £8,746 per year [NHS Employers pay scales]. For a Band 6 role starting at £20.44 per hour (excluding HCAS), the annual salary at 37.5 hours per week would be around £39,858, plus the HCAS supplement. This illustrates that London roles often include additional allowances that push total compensation above the UK median.

Remember that the figures provided are estimates; actual pay depends on your specific contract, overtime rules, and any London weighting or location allowances.

Key Takeaways

• The UK median full-time annual salary is £39,039 (ONS ASHE 2025), but London-specific figures are not published in the latest search results.
• Hourly-to-annual conversion relies on your contracted hours per week. A common full-time assumption is 37.5 hours per week, but part-time workers should use their actual hours.
• London weighting, as seen in NHS HCAS, can add thousands to base pay, making London salaries higher than the national median.
• Always verify your pay with your contract and official GOV.UK guidance, as assumptions about hours and overtime can vary.
