Site Maintenance Engineers Considering Field Service Roles
For many Site Maintenance Engineers, the idea of moving into a Field Service Engineer role is appealing. Field service can offer more variety, exposure to different industries and equipment, and in many cases stronger earning potential through overtime, travel pay or bonuses.
However, it is a different lifestyle and a different type of pressure. This guide explains what a Field Service Engineer role typically involves, the pros and cons compared to site maintenance, and the key questions to ask before making the move.
WHAT IS A FIELD SERVICE ENGINEER?
A Field Service Engineer is responsible for installing, commissioning, maintaining and fault-finding machinery or equipment at customer sites. Depending on the business, this could involve:
• Reactive breakdown support
• Planned service and preventative maintenance
• Installation and commissioning
• Upgrades, modifications and retrofits
• Customer training and handover
• Documentation and service reporting
Field Service Engineer jobs are common across UK manufacturing and machinery environments, including special purpose machinery, packaging, automation, inspection systems, conveyors, robotics, filling, labelling, processing and other industrial equipment.
WHY SITE MAINTENANCE ENGINEERS CONSIDER FIELD SERVICE ROLES
Many Maintenance Engineers reach a point where they want one (or more) of the following:
• Less repetition and more variety than a single site offers
• Better progression routes into commissioning, controls, projects or leadership
• Improved earning potential (often linked to travel and overtime)
• A day-based role after years of shifts (depending on the employer)
• More autonomy and ownership of work
Field service isn’t “better” than site maintenance, it’s just different. The key is choosing a role that fits your priorities and lifestyle.
THE PROS OF MOVING INTO A FIELD SERVICE ENGINEER ROLE
1. Variety of Machinery, Sites and Problems
On-site maintenance can become repetitive. Field service typically exposes you to different customers, processes and equipment, which can accelerate your learning and broaden your CV.
2. Strong Technical Development
Many field service roles build capability in areas such as:
• Commissioning and acceptance testing
• Controls and automation exposure (PLCs, sensors, safety circuits)
• Reading and working from electrical schematics
• Root-cause fault diagnosis (rather than quick fixes)
• Mechanical and electrical integration
This can open doors into Controls Engineer, Commissioning Engineer, Project Engineer or Technical Support roles.
3. More Autonomy
Field Service Engineers are often trusted to manage their own workload, plan visits, and make decisions on-site. If you enjoy ownership and responsibility, this can be a big positive.
4. Earning Potential
Not every role pays more basic salary than site maintenance, but many field service packages include:
• Overtime
• Travel time payments
• Call out / standby
• Expenses and overnight allowances
• Company vehicle (often private use)
Total earnings can be higher, but it depends heavily on how the employer structures pay.
5. Day-Based Work (Often)
Many Field Service Engineer roles are Monday–Friday days. This is a key driver for engineers coming off shifts, although travel and occasional weekend work can still apply.
THE CONS AND TRADE-OFFS TO CONSIDER
1. Travel and Time Away From Home
This is the biggest reality check.
Some Field Service Engineer jobs are genuinely local, but many involve:
• Regular long-distance travel
• Early starts and late finishes
• Overnight stays
• Unpredictable schedules when breakdowns happen
If work/life balance is the main reason for moving, make sure the role genuinely supports that.
2. Working Alone and Under Pressure
On-site maintenance usually has a team around you. In field service, you may be the person expected to fix it, represent the company, and keep the customer calm, often alone.
3. Customer-Facing Expectations
Field service is not just engineering. It also involves:
• Communicating clearly with operators, supervisors and managers
• Managing expectations when parts aren’t available
• Writing reports and explaining faults
• Keeping professionalism when customers are stressed
If you prefer to stay off the “front line”, this may feel uncomfortable at first.
4. Less Control Over Your Day
On-site maintenance can be hectic, but it’s one site. In field service, your plans can change quickly:
• A job runs over
• A customer escalates a breakdown
• A part is missing
• Another call-out lands late afternoon
5. Skills Gaps Can Show Up Quickly
A good maintenance engineer can still struggle in field service if they haven’t had exposure to:
• Reading schematics confidently
• Structured fault-finding under pressure
• Controls/automation basics
• Commissioning mindset (testing, validation, sign-off)
The good news: the right employer will train and support this.
KEY QUESTIONS TO ASK BEFORE YOU ACCEPT A FIELD SERVICE ENGINEER JOB
What is the travel area, and what does “UK-wide” actually mean?
Ask for clear detail:
• Typical regions covered
• Number of overnight stays per month
• Average start/finish times
• How call-outs are managed
Is it service, breakdown, installation/commissioning, or all of the above?
Field service job titles can be vague. Clarify the split, for example:
• 70% breakdowns / 30% planned service
• 50% installation & commissioning / 50% service
• Mostly PPM with minimal reactive work
What training is provided?
Good employers will offer:
• Product training
• Shadowing with experienced engineers
• Controls or software training (where relevant)
• Safety training and site inductions
How does pay work in reality?
Don’t just ask “what’s the salary?” Ask:
• Is travel time paid? From where?
• Overtime rates and typical hours
• Overnight allowance / expenses
• Bonus structure (if any)
• Company vehicle terms (private use, fuel card, tax implications)
What support do you have when you’re stuck?
Field service shouldn’t be “sink or swim”. Ask:
• Is there a technical support desk?
• Can you phone a senior engineer?
• Are spare parts held in the van?
• What happens if you can’t fix it first visit?
WHO USUALLY SUCCEEDS WHEN MOVING FROM SITE MAINTENANCE TO FIELD SERVICE?
In our experience, the Site Maintenance Engineers who transition best into Field Service Engineer roles are typically those who:
• Enjoy fault diagnosis and problem-solving
• Are comfortable speaking with customers and managers
• Can work independently without needing constant direction
• Are calm under pressure
• Want variety and technical growth
• Have solid electrical skills (or are committed to improving them)
IS FIELD SERVICE RIGHT FOR YOU?
A move into a Field Service Engineer role can be a great step if you want variety, autonomy, technical development and stronger earning potential. But it’s worth being honest about lifestyle factors like travel, time away and customer-facing pressure.
If you’re a Site Maintenance Engineer considering the move, the best approach is to look at roles carefully, compare packages properly, and choose an employer that offers the right balance of support, training and realistic travel expectations.
