The picture is tight, and it's shifting by seniority. Engineering and construction sit among the occupations with the greatest additional employment demand between 2025 and 2030, according to Skills England's assessment of priority skills to 2030. That tells you demand is structural, not a passing spike, so planning your next hire around live role data matters more than ever.
Hiring volumes aren't moving evenly across levels. Entry-level hiring in engineering has fallen to -19% while senior hiring sits at -10%, a nine-percentage-point gap, GOV.UK's 2026 snapshot of entry-level hiring reports. If you're sizing a role, that gap is a signal: the squeeze lands hardest on junior pipelines, so where you set the seniority of your hire changes how competitive the search becomes.
Specialist and technical skills are the pinch points. 76% of engineering employers struggle to recruit for key roles, with technical and specialist sustainability skills topping the list, according to the Institution of Engineering and Technology's 2025 skills statistics. When you size a hire, be precise about the specialism: a general title hides the exact capability that's genuinely scarce.
The people you want are also on the move. 79% of UK technical professionals plan to change employers in 2026, according to recruitment firm Rise Technical's 2025/26 Insights Report, which surveyed over 500 employers and 1,000 candidates. That's an opportunity as much as a risk: a large share of skilled engineers are open to the right move, so a well-sized, well-timed role can reach people who weren't on the market a year ago.
Where will those people come from? For engineering, the vast majority of new hires come from the resident labour force, indicating low reliance on international recruitment, GOV.UK's review of professionals in IT and engineering finds. So your sizing work is really about competing for UK-based talent, which raises the value of speed and a sharp specification.
Start with the data, then work backwards to the role. First, fix the seniority against live demand: with the entry-level and senior gap running at nine percentage points, GOV.UK's 2026 snapshot shows that a junior-heavy brief faces a tighter market than a senior one, so decide deliberately rather than by habit.
Second, name the specialism, not just the job title. With 76% of employers struggling on technical and specialist skills, the IET's 2025 data makes the case for listing the three or four capabilities that actually matter and dropping the rest. A tighter spec reaches a more relevant group of people faster.
Third, build for people who are already looking. Since 79% of UK technical professionals plan to move in 2026, Rise Technical's report suggests the window is open now, so a quick, respectful process beats a slow one. Confirm your scope, line up your interviewers and agree your decision-makers before you open the role.
