Management Consultant Salary: Understanding Hourly Rates and Annual Pay

When researching a management consultant salary in the UK, it’s easy to fall for common myths about how hourly pay translates into annual earnings and how overtime is handled. This article uses official data from the Office for National Statistics (ONS) Annual Survey of Hours and Earnings (ASHE) and GOV.UK National Living Wage rates to set the record straight.

Myth 1: Hourly Rate × 40 Hours × 52 Weeks = Your Annual Salary

Many job listings for management consultants quote an hourly rate, but assuming a 40-hour week every week of the year can be misleading. The ONS defines full-time work as more than 30 paid hours per week (or 25+ for teaching professions). For most professional roles, a standard contracted week is 37.5 hours. Using 37.5 hours is a more realistic baseline for converting an hourly rate to an annual salary.

For example, if a management consultant earns £35 per hour, the rough annual equivalent is:

£35 × 37.5 hours/week × 52 weeks = £68,250 per year

However, this assumes no unpaid overtime, no unpaid holidays, and that you work every week of the year. In reality, management consultants often work longer hours, especially during busy project phases. Some of that extra time may be unpaid, which means your effective hourly rate drops. Always check your contract for overtime policy.

Myth 2: Overtime Is Always Paid at a Higher Rate

In many industries, overtime is paid at 1.5× or 2× the normal hourly rate. But for management consultants, overtime is typically not paid separately. Most consultants are on a fixed annual salary that is meant to cover all hours worked, including occasional late nights. Some firms offer time off in lieu or performance bonuses, but these are not guaranteed.

ONS ASHE data shows that for professional occupations, overtime pay is a small fraction of total earnings. The median hourly pay excluding overtime for all UK employees in April 2025 was £17.96, while the median including overtime was similar. This suggests that overtime pay is not a major component for most salaried professionals.

If you are considering a contract role where you are paid by the hour, clarify whether overtime is paid and at what rate. The salary data page on our site provides more context on typical earnings across occupations.

Myth 3: London Weighting Doesn’t Matter Much

A management consultant salary in London can be 10–20% higher than the same role elsewhere in the UK, reflecting higher living costs. ONS ASHE Table 3 provides regional breakdowns by occupation. For example, median hourly pay for all employees in London is significantly above the UK median. When converting an hourly rate to annual salary, consider whether the rate includes London weighting or a regional allowance.

If you see a job advertised at £40 per hour outside London, the equivalent London rate might be £45–£48 per hour. Always factor in location when comparing offers.

What the Official Data Says

ONS ASHE is the most comprehensive source of UK earnings data. It is used to set the National Living Wage and inform pay review bodies. In April 2025, the National Living Wage for employees aged 21+ was £12.21 per hour. For a full-time worker on 37.5 hours per week, that equates to approximately £23,809 per year.

Management consultants typically earn well above this. The low-pay threshold (two-thirds of median hourly pay) was £11.97, and the high-pay threshold (1.5 times median) was £26.94. Many management consultant roles fall into the high-pay category, especially at senior levels.

To find the exact median hourly or annual pay for management consultants (SOC 2010 code 2423), you would need to consult ASHE Table 29, which provides four-digit occupational breakdowns. The search results did not include that specific table, but ONS publishes it annually.

How to Use Hourly-to-Salary Conversion Correctly

A simple rule of thumb: annual salary ≈ hourly rate × hours per week × 52. But remember:

• Use your contracted hours, not assumed hours.
• Subtract unpaid leave if you are not paid for holidays (most salaried roles include holiday pay).
• Add London weighting if applicable.
• Do not assume overtime pay unless stated.

Final Thoughts

Understanding the true value of a management consultant salary requires looking beyond the headline hourly rate. Myths about overtime, standard working weeks, and location adjustments can lead to underestimating or overestimating your take-home pay. Rely on official sources like ONS ASHE and GOV.UK for benchmarks, and always read your employment contract carefully.
