I think this one may have been discussed in the past.
Make 'Engineer' a protected title
Responsible department: Department for Business, Innovation and Skills
Engineering suffers from an image problem. People believe that engineers simply fix things, but we don't: we invent things. Unfortunately the false image is propagated by hundreds of companies out there who term repair-persons and equipment installers 'Engineers'. Engineering suffers from a lack of graduates, and at a time people are looking to manufacturing to fix the economy we need all the graduates we can get. Sadly they are put off by the false image of engineering. It is thus proposed that the title 'Engineer' is protected legally, like 'Doctor' or 'Architect'. It would be restricted to those who are professional engineers or product designers, or those who have retired from the industry.
