I wouldn't put too much emphasis on a year in industry. Yes, it's experience and experience is paramount, but you don't have to do a year in industry to get experience: you can do summer placements, like what I did. Ultimately I haven't seen any evidence that suggests that employers vastly favour a year in industry compared to a summer placement, especially if you have multiple summer placements.
If you do a year in industry, and this adds a year to the length of the degree as most do, you have to consider that you're spending a year earning a placement wage (typically between £15,000-£20,000) when you could instead graduate a year sooner and be earning a graduate wage (see Unistats for average graduate salaries of engineering courses). The engineering market isn't so tight that a year out is required to secure a job.
