Zoologist Salary UK: What the Latest ONS Data Shows

If you are considering a career as a zoologist or are already working in the field, understanding typical pay levels is essential for negotiating your salary or planning your finances. The most authoritative source for UK earnings is the Office for National Statistics (ONS) Annual Survey of Hours and Earnings (ASHE). However, the ONS does not publish a separate figure for 'zoologist' – instead, zoologists are grouped under the broader category of conservation professionals (Standard Occupational Classification code 2454). This group includes ecologists, wildlife biologists, and other environmental scientists.

Median Pay for Conservation Professionals (2025 Provisional)

According to the latest ASHE data (April 2025 provisional), the median gross annual pay for full-time conservation professionals in the UK was £37,949. The median hourly rate (excluding overtime) was £19.77. To put this in context, the UK median full-time annual earnings across all occupations were £39,039, so zoologist salaries are very close to the national average.

At the lower end, the 20th percentile annual pay was £29,439, while at the upper end, the 80th percentile reached £42,599. This range reflects differences in experience, employer type, and location. For example, conservation professionals working in London earned a median hourly rate of £26.00, while those in the South East earned £17.52 per hour.

How Zoologist Salary Compares to the National Living Wage

The National Living Wage (NLW) for employees aged 21 and over was £12.21 per hour from April 2025. Even at the 20th percentile (£15.91 per hour for conservation professionals), zoologist pay is well above the NLW. However, entry-level roles or internships may pay less, and some positions in charities or research institutes may offer lower starting salaries.

Converting Hourly Rate to Annual Salary

When you see an hourly rate for a zoologist role, you can estimate the annual equivalent using the formula:

Annual salary ≈ hourly rate × contracted hours per week × 52 weeks

For a standard full-time contract of 37.5 hours per week, the median hourly rate of £19.77 gives:

£19.77 × 37.5 × 52 = £38,551 (close to the ASHE median of £37,949).

If you work part-time, simply adjust the hours. For example, 20 hours per week at the same rate gives approximately £20,561 per year. Use our hourly calculator to try different scenarios.

Factors That Affect Zoologist Pay

Several factors can push your salary above or below the median:

• Employer type: Government agencies (e.g., Natural England, DEFRA) and large conservation charities often have structured pay scales. Universities may pay according to academic grades. Private sector environmental consultancies may offer higher rates but with less job security.
• Experience and qualifications: A PhD or chartered status (e.g., Chartered Environmentalist) can lead to higher pay. Senior roles such as principal zoologist or head of conservation can exceed £50,000.
• Location: London and the South East command higher pay to offset living costs. The ONS data shows London median hourly pay for conservation professionals at £26.00, compared to £18.30 in Scotland.
• Overtime and unsocial hours: Fieldwork may involve irregular hours, but ASHE figures exclude overtime. Check your contract for overtime rates or time off in lieu.

Caveats and Important Notes

• ASHE data is based on a 1% sample of PAYE records and is provisional for 2025. Revised figures may differ slightly.
• The figures shown are for full-time employees who have been in the same job for at least a year. They include pay affected by absence (e.g., sick leave).
• Hourly-to-annual conversions assume a steady contracted week with no unpaid overtime, bonuses, or salary sacrifice. Actual take-home pay depends on your specific rota, holiday pay method, and any London weighting.
• Always check your employment contract and official GOV.UK guidance for the most up-to-date National Minimum Wage and tax information.

Summary

While there is no single 'zoologist salary' published by the ONS, the conservation professionals category provides a reliable benchmark. With a median annual pay of £37,949 and hourly rate of £19.77, zoologists earn close to the UK average. Use the conversion rule of thumb (hourly × 37.5 × 52) to compare offers, and remember that location, employer, and experience can significantly affect your earnings.
