Critical Maintenance Engineer

Permanent

Field based role covering Oxfordshire & Berkshire

Up to £30k base salary + overtime & bonus

Want to work in a role where your expertise genuinely keeps people safe?

At SMS Environmental, we don’t just maintain water systems — we protect the health of people in hospitals, schools, and workplaces across the UK.

As a Critical Maintenance Engineer, you’ll play a vital role in ensuring water systems remain safe, compliant, and operating at the highest standards.

We’re a people-first business where your knowledge is valued, your development is supported, and your work makes a real impact every single day.

What’s in it for me?

We believe your skills deserve proper recognition — not just in pay, but in how you’re supported day-to-day:

37.5 hours per week (Monday–Friday) with overtime available at double rate
Company vehicle and fuel card for business use
Company iPad and mobile phone
Full uniform, tools, and PPE provided
Private Medical Care or alternative Cash Plan after 2 years’ service
Enhanced Sick, Maternity and Paternity Leave
City & Guilds Affiliated Training Programme to support your professional growth
Employee Discount Scheme – save up to £240 per month on food and groceries
Clear progression pathways within a growing business
Supportive team culture where your work is recognised

What will I be doing?

You’ll be part of our Operations team, working across a variety of client sites to deliver essential water hygiene and maintenance services. No two days are the same, but you can expect to:

Carry out planned preventative maintenance (PPM) on water systems
Conduct water sampling, flushing, and treatment activities
Ensure compliance with ACOP L8, HSG274, and water hygiene regulations
Accurately record all site work using company systems and software
Identify and report system issues or non-compliances to Account Managers
Build strong relationships with clients and represent SMS professionally on-site
Support and mentor junior engineers where required

You’ll have the autonomy to manage your workload, with the support of an experienced team behind you.

What do I need to be successful?

We’re looking for someone who knows their stuff and takes pride in doing things properly. You’ll need:

Proven experience in water hygiene, water treatment, or Legionella control
Strong understanding of water hygiene regulations and best practices
Ability to work independently and manage your time effectively
Confident communication and client-facing skills
Awareness of Health & Safety practices (COSHH, risk assessments, etc.)
Full UK driving licence

If you’ve worked across sectors like healthcare, education, or commercial environments — even better.

Who is SMS Environmental?

We’re a nationwide leader in water hygiene, safety, and environmental compliance — known for doing things the right way.

Our engineers are at the heart of everything we do, and we make sure they’re equipped, supported, and recognised for their work every step of the way.

At SMS, you’re not just another engineer — you’re a trusted expert making a real difference.

If you’re ready to take the next step in your water hygiene career and join a team that values quality, safety, and your long-term growth — we’d love to hear from you.

Apply today and be part of something that truly matters.
