Take-home at England, Wales and Northern Ireland rates. Not published means ONS did not publish that figure because the estimate is not reliable enough. ONS rates the median for mechanical engineers as precise: its sampling error (coefficient of variation) is 4.7%. ONS estimates about 52,000 full-time employee jobs in this occupation. ONS says job counts like this are indicative only.
Where mechanical engineers rank
The median for mechanical engineers ranks 49th of 362 occupations on this site, in the top quarter, and 28th of 91 in professional occupations. It is £12,071 (30.9%) higher than the UK median of £39,039 for all full-time employee jobs. ONS change on the previous year: the median for mechanical engineers rose 9.3%, more than the 4.3% rise in the UK median for all full-time jobs. 74 of 358 occupations had a change this large in either direction. ONS figures for one occupation come from a sample, so they can move a lot from one year to the next.
Jobs with the nearest medians: Quantity surveyors (£52,537), Electronics engineers (£52,518), Civil engineers (£51,366), Veterinarians (£51,058), Optometrists (£51,030) and Barristers and judges (£50,915).
How spread out pay is
The middle half of full-time mechanical engineers earn between £39,125 and £62,237, a gap of £23,112, or 45.2% of the median. That is £1,635 narrower than the £24,747 gap for all UK jobs, and the 45th widest of the 223 jobs where ONS published both figures, one of the wider middle ranges.
The mean for mechanical engineers (total pay divided by the number of employees) is £55,148, which is £4,038 (7.9%) higher than the median. When the mean is above the median, a smaller number of higher salaries are pulling the average up. For all UK full-time jobs the mean is 24.3% above the median, so the gap for mechanical engineers is smaller.
