Demand is climbing fast, and it's not slowing down. Skills England lists engineering among the occupations with the greatest additional employment demand between 2025 and 2030 GOV.UK - Assessment of priority skills to 2030 (Skills England). Its 2026 report goes further, naming digital, engineering and construction as the occupations that appear most commonly among priority roles, many already under high recruitment demand and expected to keep growing strongly GOV.UK - Skills England annual skills report 2026.
The scale is significant. Skills England projects demand for key occupations to grow by nearly 25% over the next decade, with 1.8 million new priority jobs expected by 2035 GOV.UK - Landmark report sets out action to address key skills gaps (Skills England). For the water sector, where years of underfunding held back recruitment, renewed investment lands right as this competition for engineers intensifies.
The pressure is already visible. The Institution of Engineering and Technology found that 76% of engineering employers struggle to recruit for key roles, with technical and specialist sustainability skills topping the list Institution of Engineering and Technology (IET). Those sustainability skills sit at the heart of modern water infrastructure work, from cleaner treatment processes to reducing leaks and carbon.
Two dynamics shape the hiring picture. First, retention is fragile. Rise Technical's 2025/26 Insights Report found that 79% of UK technical professionals plan to change employers in 2026, drawn from a survey of over 500 employers and 1000 people looking for work Engineering and Technology Jobs (IET) / Rise Technical. So even as investment funds new positions, existing teams are in motion, which means employers compete for the same experienced people.
Second, the pipeline into engineering is thin at the bottom. Entry-level hiring in engineering has fallen to -19%, while senior hiring sits at -10%, a nine-percentage-point gap GOV.UK - A snapshot of entry-level hiring in the UK. That gap matters for the water sector: if fewer junior engineers enter now, the senior specialists needed to run treatment works and networks in a decade won't exist in the numbers required.
There's also a home-grown angle worth planning around. For the engineering profession, the vast majority of new hires come from the resident labour force, which points to low reliance on international recruitment GOV.UK - Professionals in IT and engineering. In practice, that means water sector employers largely draw from the UK talent pool, so growing and keeping domestic skills is central to filling these roles.
Start by widening who you consider. With 76% of employers struggling to recruit key roles Institution of Engineering and Technology (IET), rigid must-have lists shrink an already small pool. Focus on the core technical competence a water engineering role genuinely needs, then treat adjacent experience, from other utilities or process engineering, as transferable.
Next, protect your entry-level intake. The gap between falling junior hiring and senior hiring GOV.UK - A snapshot of entry-level hiring in the UK is a warning: employers who train apprentices and graduates now build the senior bench they'll need as investment programmes mature. Pair every new project with a clear development route so early-career hires can see a future in the sector.
Then move quickly and communicate clearly. When 79% of technical professionals are open to moving Engineering and Technology Jobs (IET) / Rise Technical, a slow, vague process loses strong people to faster employers. Set out the role, the mission and the progression up front, keep interview stages tight, and give feedback within days rather than weeks.
When demand is high and the right engineers are hard to find, speed and reach make the difference. Reed.ai searches a database of 15 million candidates to surface people who match the technical and sustainability skills water roles now depend on, and it manages recruitment end to end so your team can stay focused on delivery. Our recruitment agent manages recruitment end to end for 8% on a successful hire, with no monthly fee and no upfront cost.
