Average Clinical Data Reviewer Salary in Guernsey for 2026

How much does a clinical data reviewer make in Guernsey?

A typical clinical data reviewer working in Guernsey brings home around 6,775 GBP a month before tax. Entry-level pay starts near 36,500 GBP, and the top of the ladder reaches roughly 130,400 GBP for the most experienced and specialised people in the role.

The wide gap between low end and top end reflects how much pay can vary inside the same job title. A junior clinical data reviewer working at a small local employer earns very different money from a senior at a multinational. Skills, employer, city and years in the seat all push the number around. For a cross-country comparison, see the clinical data reviewer salary in United Kingdom or Jersey, both of which pay in the same currency.

How clinical data reviewer pay ranges in Guernsey

A good way to think about salary in Guernsey is to look at the distribution rather than the headline average. Half of all clinical data reviewers in Guernsey earn less than 91,000 GBP a year, and the other half earn more. That middle number is the median, and it is usually more useful than the average for answering "is my pay normal here".

Looking at the quartiles fills in the picture. A quarter of earners take home less than 58,600 GBP (the 25th percentile), and a quarter clear 119,700 GBP (the 75th percentile). The middle 50% of clinical data reviewers sit somewhere inside that band, which is where the typical reader of this page probably lives.

The very lowest reported salaries sit around 36,500 GBP. The highest stretch to 130,400 GBP, though only a small fraction of earners ever reach that level. If you are deciding whether your own offer or current pay is reasonable, work out which of those four bands you would fall into and use that as your reference point.

Clinical data reviewer pay by experience in Guernsey

Years of experience is the single biggest lever on pay for a clinical data reviewer in Guernsey, ahead of education and almost any other single factor. The longer you have been in the role, the more your employer can trust you to handle complexity, mentor others and act independently, all of which command higher pay. The chart below shows how the typical clinical data reviewer salary changes as you move through the career ladder.

The single largest jump on the ladder is from 2 - 5 Years to 5 - 10 Years, where pay rises by about 48%. That is the point at which a clinical data reviewer typically goes from "competent in the role" to "the person other people in the team learn from", and the market pays well for that step.

Clinical data reviewer pay by education in Guernsey

Education sits alongside experience as one of the biggest factors driving clinical data reviewer pay in Guernsey. Higher qualifications consistently pull higher salaries, but the size of the gap tends to be smallest at junior levels and widens as people move up. Two people in the same role with the same years of experience but different degrees can end up earning very different money once they reach mid-career.

Clinical data reviewer gender pay gap in Guernsey

The gender pay gap is a stubborn feature of almost every labour market, and Guernsey is no exception. Male clinical data reviewers in Guernsey earn an average of 89,400 GBP a year, while female clinical data reviewers earn around 74,200 GBP. That works out to a 20% gap in favour of men, even when comparing people doing the same work.

A pay gap of this size has a real long-term cost. Over a typical thirty-year career it can add up to several years of pay, and it compounds through pensions, retirement contributions and bonus-linked stock. Some of the gap is explained by women being more likely to work part-time, take career breaks, or be steered toward lower-paying specialisations. Some of it is straightforward unequal pay for the same job, which is harder to defend.

Pay raises for a clinical data reviewer in Guernsey

Most countries hand out at least some kind of pay raise every year, typically when an employee's contract is reviewed or as a cost-of-living adjustment to keep wages roughly in step with inflation. The rhythm and size of those raises varies hugely between industries.

A typical worker doing this role in Guernsey sees a raise of about 6% every 28 months, which works out to roughly 3% on an annual basis. That figure is the typical underlying rate; in years where inflation runs high you can usually expect a bit more, and in flat-economy years a bit less.

Across all jobs in Guernsey, the national average raise is around 5% every 28 months.
