At SMS Environmental, we don’t just maintain water systems — we protect people’s health and keep environments safe from Legionella and other water hygiene risks. If you’re a skilled Water Hygiene Engineer who takes pride in doing things right the first time, we want you on our team.

You’ll be out on the road, visiting a variety of client sites — from hospitals and schools to commercial and industrial settings — making sure their water systems are compliant, clean, and safe.

  274, and other water hygiene regulations
• Recording and reporting site activities accurately using company systems
• Spotting and reporting system issues before they become bigger problems

• Understands water hygiene legislation and best practice
• Communicates clearly and confidently with clients and colleagues
• Works well independently and manages time effectively
• Holds a City & Guilds qualification (or equivalent) in Water Hygiene
• Has a full UK driving licence
• Ability to pass Disclosure and Barring Service clearance (Enhanced DBS check)

Bonus points if you’ve got a knack for problem‑solving and love a job that keeps you moving and learning.

We take care of our people — because you take care of our clients. Here’s what you can expect:

• 37.5 hours per week – 8am–4pm (Monday–Friday)
• Paid overtime available
• 22 days holiday per year plus bank holidays, with an extra day for your birthday after 2 years’ service
• Company iPad & Mobile Phone
• Brand new uniform, equipment, tool bag & PPE
• Modern, fully serviced company van with a business fuel card
• Trade cards for quick access to new supplies

• Enhanced sick, maternity & paternity leave
• 24/7 Employee Assistance Programme
• Employee discount scheme – save up to £240/month on food & groceries
• Core Values Champions Rewards – quarterly peer nominations with vouchers
• Annual development & review process – because we believe in your progression

We’re not your average water hygiene company. We’re a team of passionate professionals who value safety, integrity, and continuous improvement. Every member of our team plays a vital role in keeping people safe and facilities compliant — and we make sure you feel recognised and rewarded for the work you do.
