Critical Spares Strategy & Component Supply That Protects Your Production
From PLC modules to safety components and industrial network devices. We identify, classify, and supply essential spares that eliminate catastrophic downtime and keep your temperature-critical operations running.
Trusted by UK manufacturers in food, building management systems, refrigeration & process engineering
Proactive Strategy
Risk-Based Assessment
We audit your control systems to identify single points of failure and classify components by criticality, lead time, and obsolescence risk.
Obsolescence Protection
Future-Proof Your Systems
Strategic spares planning for aging equipment and end of life components, protecting against forced upgrades during critical failures.
Technical Excellence
Trusted guidance on PLC and panel spares
We provide technically informed advice on critical PLC and control panel spares to ensure system compatibility, resilience, and minimised downtime.
Whether you need basic spares strategy for a single production line or comprehensive component management across multiple sites, our team has the expertise and supply channels to deliver exactly what your operation requires.
Discuss Your RequirementsCritical Spares Management for Industrial Control Systems
For over four decades, JBB has been protecting UK manufacturers and temperature-critical facilities from preventable downtime through strategic component management. From basic control panels to complex control systems, we bring systematic risk assessment and practical spares planning to every operation.
Risk-Based Analysis
Comprehensive audit of your control panels identifying single points of failure, component lead times, and obsolescence risks with prioritized spares recommendations.
Rapid Availability
Supply of genuine PLC modules, I/O cards, HMIs, safety relays, network devices, and power supplies ensuring critical components are available when failures occur.
Documentation Protection
Complete backup of PLC programs, HMI configurations, and electrical schematics with secure storage and documented replacement procedures for your maintenance teams.
Obsolescence Management
Forward-looking assessment of aging equipment and end-of-life components, protecting against scenarios where failures force unplanned system replacements or extended outages.
Common Critical Spares Challenges We Solve
Without a structured spares strategy, component failures create operational headaches that impact your business
Long OEM Lead Times
PLC modules, CPUs, and specialist components often have 6-10 week delivery times, turning minor component failures into extended production shutdowns.
Obsolete Components
Aging control systems using end-of-life PLC series face impossible replacement scenarios when critical modules fail without readily available alternatives.
Unidentified Failure Risks
Lack of systematic assessment means facilities don't know which component failures will cause complete production loss versus minor disruption.
Missing Program Backups
Inadequate or outdated PLC program archives causing extended recovery times during component replacement and making simple fixes unnecessarily complex.
Uncontrolled Costs
Stocking every possible spare is financially unrealistic, but failing to stock critical components costs far more in emergency downtime and rush shipping.
What's Included in Our Critical Spares Service
From initial assessment to ongoing supply management, we handle every aspect of your critical spares strategy
Critical Spares Audit
We analyse your control panels, document all components, and assess failure risks to identify which parts pose the greatest threat to your operation.
Risk Classification
Each component is evaluated for failure impact, lead time exposure, and obsolescence status to create a prioritised spares matrix with cost-benefit analysis.
Component Supply
We source and supply genuine PLC modules, I/O cards, HMIs, safety components, and network devices from authorised distributors with full traceability.
Program Backup & Documentation
You receive complete PLC program backups, HMI configurations, electrical schematics, and documented replacement procedures for rapid restoration.

Trusted by operations and engineering leaders across the UK
"I have worked with the team at JBB Electrical on a wide range of projects and reactive works for over 15 years. They consistently complete jobs to an excellent standard and are always a pleasure to deal with. Their technical knowledge is a huge benefit to both myself and my customers, and nothing is ever too much trouble for the team. They regularly go above and beyond, and I would not hesitate to recommend JBB Electrical"
Ian Ross
Service Manager, EJM
"The team at JBB Electrical have been integral to the implementation of the proof-of-concept large scale energy‑sharing district heating & cooling network at SmartParc’s food production campus in Derby. JBB’s wealth of knowledge and experience in industrial controls and automation helped integrate the multiple systems and platforms required for seamless control and monitoring of the energy centre plant and park network. JBB have also secured and successfully delivered the electrical subcontract works associated with the industrial cooling installations for all tenants on the park thus far. All under competitive tender and ambitious installation programmes. All projects have been completed on time, within budget and to the highest quality standards. I can highly recommend JBB as partner of choice for complex industrial electrical and automation projects."
