| Primary focus | Filling the vacancy as fast as possible to close the deal. | Finding the right long-term hire for your technical requirements and company values. |
| Method | Forwards a high number of unscreened or poorly matched CVs from a database. | Consults on the role, interviews candidates in depth and delivers a shortlist of qualified, screened candidates. |

| Market insight | A generalist view across many industries. | Specialist expertise in the UK’s engineering and manufacturing sectors. |
| End result | A placement that may or may not last. The relationship ends when the invoice is paid. | A valuable new employee, with support beyond the placement to make sure they settle in. |

We also partner with select international manufacturing clients supporting their UK-based operations.
UK manufacturers have hired cautiously in 2026: Make UK’s employment balance fell from +15% to +3% in the third quarter. Engineering is still one of the more resilient parts of the jobs market.
UK manufacturing generates around £220 billion of output and supports some 2.6 million jobs, according to Make UK. Across the wider economy, about 6.3 million people work in engineering and technology roles, around a fifth of the UK workforce (EngineeringUK).
Food and drink is the largest manufacturing subsector by value added, followed by pharmaceuticals. In 2024 automotive contributed £21.4 billion of gross value added and employed 132,000 people, while aerospace added £13.6 billion and supported 100,000 direct jobs (Department for Business and Trade). Make UK expects demand from renewables, data centres and defence to shape the sector through 2026 and 2027.

Absolutely. From single-site producers to multinational OEMs, we tailor our recruitment approach to your size and structure. Current clients range from 6 employees to several thousand.
Our head office is in Cardiff, and our team supports employers nationwide across England, Scotland and Wales.
The top skills currently include predictive maintenance, industrial IoT integration and collaborative robotics (cobots). Employers are no longer just looking for mechanical proficiency. They need multi-skilled engineers who understand how software and hardware interact on modern production lines.
Active candidates are browsing job boards; passive candidates are high performers already in a role. Most of the top 10% of engineering talent is passive. We use our 20-year network to headhunt engineers who are not looking at traditional adverts.
Salaries vary significantly between hubs such as South Wales, the Midlands and the North of England. We benchmark from current placements and market intelligence, so your offer is competitive enough to stop rivals counter-offering.
