How treatment services director 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 treatment services directors in Guernsey earn less than 280,400 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 177,200 GBP (the 25th percentile), and a quarter clear 371,100 GBP (the 75th percentile). The middle 50% of treatment services directors sit somewhere inside that band, which is where the typical reader of this page probably lives.

The very lowest reported salaries sit around 118,900 GBP. The highest stretch to 409,800 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.

Treatment services director pay by experience in Guernsey

Years of experience is the single biggest lever on pay for a treatment services director 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 treatment services director salary changes as you move through the career ladder.

    134,700 GBP
  • 2-5 Years

Treatment services director gender pay gap in Guernsey

The gender pay gap is a stubborn feature of almost every labour market, and Guernsey is no exception. Male treatment services directors in Guernsey earn an average of 281,100 GBP a year, while female treatment services directors earn around 236,700 GBP. That works out to a 19% 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.
