Cutting Engineering Time-to-Hire from 47 Days to Under 21
UK engineering roles take an average of 47 days to fill. The employers winning the best talent are doing it in three weeks - here is the operating model behind that.
EngineeringUK and the Institution of Engineering and Technology both report that engineering vacancies in the UK take 40–50 days to fill on average, against a national cross-sector benchmark of 27 days. Every additional week of vacancy in a production-critical role typically costs a mid-sized manufacturer £8,000–£15,000 in lost output, overtime and contractor cover.
The 21-day target is not aspirational - it is operational. The employers we see hitting it consistently share five characteristics: a pre-approved scorecard, a named decision-maker, two reserved interview slots per week, in-principle salary authority delegated to the hiring manager, and a 48-hour decision SLA after final stage.
The single largest cause of slippage is interview scheduling. Holding two fixed slots in the hiring manager's calendar - for example Tuesday morning and Thursday afternoon - removes the back-and-forth that typically adds 7–10 days. Candidates self-book; recruiters do not chase availability.
The second largest cause is post-offer drift. Offers that are extended verbally but not followed up in writing within 24 hours have a measurable drop in acceptance rate. The best practice is to send a one-page offer summary the same day, with the full contract following inside 72 hours.
Finally, structured debriefs after each interview - 15 minutes, scorecard-driven, decision recorded - prevent the 'let's keep looking' loop that adds weeks to otherwise viable processes. Discipline here is worth more than any sourcing tool.
