The survey also demonstrated that the benefits of professional registration are not limited to engineers at the higher levels of the career ladder, with professionally registered respondents at every level of seniority enjoying better pay than their unregistered colleagues.
These differences were most pronounced at Director level, where registered respondents earn on average £11,000 more, while the pay gap at the junior/graduate engineer level was just £2,000.
Commenting on the findings, Alasdair Coates, CEO of The Engineering Council (the body that regulates registration of UK engineers), said: “The Engineering Council notes the higher average salaries commanded across all sectors by professionally registered engineers in this survey. Professional registration is an internationally recognised assessment of your competence that demonstrates your commitment to employers and clients; these responses indicate the impact registration can have on earning potential. Registrants consistently tell us that achieving professional registration has increased their credibility, helped them gain promotion or win more business. These responses suggest that professional registration can also boost earnings, again demonstrating that it is an investment in your future.”
