Researchers play a crucial role within the science and biotech industry, contributing valuable insights that inform decision-making and strategic planning. They are often part of multidisciplinary teams, collaborating with scientists, analysts, and project managers to gather and interpret data that drives innovation and growth. Their work supports various sectors, from healthcare to environmental science, ensuring that organisations remain competitive and informed about the latest developments in their fields.
The primary responsibility of a researcher involves conducting thorough online research to collect relevant information on specific topics. This may include accessing academic journals, databases, and other resources to extract data that can influence business strategies. Researchers may also engage with libraries and attend conferences to enhance their knowledge and gather insights that are not readily available online, thus enriching the overall research process.
Researchers typically operate in an office environment, utilising computers and various software tools to analyse data and present findings. They may work independently on specific projects or collaborate in small teams, depending on the nature of the research. The role often requires strong analytical skills, attention to detail, and proficiency in using tools like Microsoft Office and Excel, which are essential for data management and reporting.
As a mid-level analytical role in Science and Biotech, 'Researcher (General/Unknown Type)' has moderate automation risk (score: 55) as some tasks can be automated while others require human judgment. Job displacement risk is low (13) due to the essential human elements of this position. AI augmentation potential is high (100), meaning AI tools can significantly enhance productivity and decision-making.
Scores are on a 0-100 scale. Automation and displacement scores reflect risk; augmentation reflects opportunity to work effectively with AI tools.

Understanding where the role of a researcher (general/unknown type) sits in the UK pay spectrum is the first step to managing tax effectively.
Your effective tax rate is the percentage of your gross income that goes to Income Tax and National Insurance. It's typically lower than the 20% basic rate because the first £12,570 is tax-free.
People in this role typically work under these employment arrangements:
Estimated based on industry patterns: many researchers are employed by universities, research institutes, or biotech firms (PAYE). A significant minority work as freelance consultants or short-term contract researchers (self-employed). A grey area exists for grant-funded researchers on fellowships that may not be clearly employment, as per HMRC BIM65151.
If you're employed as a researcher (general/unknown type), your employer handles tax and National Insurance through PAYE. Here's what's actually happening behind the scenes.
Under PAYE, your employer deducts Income Tax and Employee National Insurance from your gross pay before you receive it. Here's a breakdown for the average researcher (general/unknown type) earning £26,544/year:
| Deduction | Calculation | Amount (annual) | Amount (monthly) |
|---|---|---|---|
| Gross Pay | — | £26,544 | £2,212 |
| Personal Allowance | First £12,570 tax-free | −£12,570 | −£1,048 |
| Income Tax (20%) | £13,974 × 20% | £2,795 | £233 |
| Employee NI (8%) | £13,974 × 8% | £1,118 | £93 |
| Tax & NI Total | £3,913 | £326 | |
| Net Take-Home | £22,631 | £1,886 |
