Machinery Breakdown Insurance for Electronics Equipment (UK Guide)
Introduction
If your business relies on electronics equipment—servers, CNC controls, test rigs, production lines, medical or lab devices, comms racks, EPOS, or specialist power supplies—one unexpected failure can stop work instantly. Standard property insurance often focuses on “insured perils” like fire, flood, or theft. But many real-world breakdowns come from internal failure: a component burns out, a control board fails, a motor seizes, or a power surge damages sensitive circuitry.
That’s where Machinery Breakdown Insurance (also called Engineering Breakdown or Equipment Breakdown) comes in. It’s designed to cover sudden and unforeseen mechanical or electrical breakdown of insured equipment—often including the cost to repair or replace, and sometimes the knock-on costs of downtime.
This guide explains how machinery breakdown cover works for electronics equipment in the UK, what to look for in a policy, and how to keep claims smooth.
What is Machinery Breakdown Insurance?
Machinery Breakdown Insurance is an engineering-style policy (or section within a commercial combined policy) that covers physical damage to equipment caused by breakdown, rather than external events.
For electronics-heavy businesses, it’s especially relevant because failures are often:
- Electrical (short circuits, arcing, component burnout)
- Control-system related (PLC/drive failure, sensor failure, control board issues)
- Power quality related (surge, spike, brownout, harmonics)
- Cooling related (overheating from fan failure, blocked filters, HVAC faults)
Depending on wording, it may also extend to:
- Business interruption following breakdown
- Deterioration of stock (e.g., temperature-controlled goods)
- Increased cost of working (temporary hire equipment, overtime, expedited shipping)
What counts as “electronics equipment”?
Policies vary, but electronics equipment commonly includes:
- Servers, storage arrays, network switches, routers
- UPS systems, PDUs, battery cabinets
- Control panels, PLCs, variable speed drives, HMIs
- Production and test equipment (pick-and-place machines, reflow ovens, inspection rigs)
- Medical and lab equipment (imaging, analysers, sterilisation controls)
- Building systems with electronics (BMS controls, access control, CCTV head-end)
- EPOS systems and back-office hardware
The key is that the equipment is owned, leased, or for which you are responsible, and is declared or otherwise included under the policy schedule.
Why standard property insurance may not be enough
Many businesses assume their buildings and contents policy will respond if a critical device fails. Often it won’t.
A typical property policy is built around named or defined perils (fire, lightning, explosion, storm, flood, escape of water, theft, impact). If a circuit board fails due to internal defect, wear, or electrical arcing, the insurer may treat it as:
- Mechanical/electrical breakdown (excluded)
- Gradual deterioration (excluded)
- Faulty workmanship/defective part (often excluded, at least for the defective component)
Machinery breakdown cover is designed to fill that gap.
What Machinery Breakdown Insurance typically covers
Always check the wording, but common cover includes:
1) Sudden and unforeseen breakdown
This is the core. The failure must be unexpected and not simply “it stopped working over time.” Examples:
- A drive fails and damages associated components
- A control board burns out due to electrical arcing
- A transformer fault causes internal damage
- A compressor motor seizes, damaging control electronics
2) Repair or replacement costs
Cover usually includes:
- Parts and labour
- Specialist engineer call-out
- Rewinding motors (where applicable)
- Re-calibration and testing after repair
3) Expediting expenses (optional/limited)
Some policies help with:
- Express freight
- Overtime labour
- Emergency sourcing
4) Business interruption following breakdown (optional)
If included, this can cover:
- Loss of gross profit due to downtime
- Increased cost of working to keep trading
For electronics equipment, business interruption is often where the biggest financial impact sits.
5) Data and media (careful)
Some policies offer limited cover for:
- Data restoration
- Software reinstallation
- Media replacement
But many do not treat data as “property,” and cyber events are often excluded. If data risk is meaningful, consider cyber insurance alongside engineering cover.
Common exclusions and limitations to watch
Machinery breakdown policies can be excellent—but only if you understand the boundaries.
Wear and tear / gradual deterioration
If a component fails due to age, corrosion, or long-term overheating, insurers may argue it’s not “sudden and unforeseen.” Good maintenance records help show the failure was unexpected.
Defective part vs resulting damage
A common approach is:
- The defective component itself may be excluded
- But resulting damage to other parts may be covered
Example: a capacitor fails (excluded), but it causes board damage and damages a connected drive (covered). Wording matters.
Poor maintenance and known defects
If inspections were overdue, filters blocked, cooling fans ignored, or alarms bypassed, insurers may reduce or decline claims.
Consumables and routine servicing
Fuses, belts, filters, and routine service items are usually excluded unless damaged as part of an insured event.
Power surge and utility supply issues
Some wordings cover power surge; others restrict it or apply conditions (e.g., surge protection, UPS maintenance). If you’re in a site with unstable supply, flag it.
Cyber, malware, and remote attacks
Machinery breakdown is not cyber insurance. Damage caused by malicious code, hacking, or ransomware is usually excluded.
Manufacturer warranty and service contracts
Insurers may expect you to use warranty first. Engineering cover is not a replacement for a service contract, but it can protect you when warranty is expired or the loss goes beyond warranty scope.
Who needs Machinery Breakdown cover for electronics?
It’s worth considering if:
- A single piece of equipment can stop production or service delivery
- Replacement lead times are long (specialist boards, imported parts)
- You have contractual penalties for downtime
- You run temperature-controlled environments (server rooms, labs)
- You rely on UPS, HVAC, or power conditioning to protect equipment
Typical sectors include:
- Electronics manufacturing and assembly
- Medical device manufacturing
- Data-driven businesses (SaaS, MSPs, agencies with on-prem infrastructure)
- Laboratories and testing facilities
- Warehousing with automated systems
- Retail with EPOS dependence
How to set the right sum insured
Machinery breakdown is often arranged on a replacement value basis. Underinsuring can cause claim reductions.
A practical approach:
- List critical equipment (make/model/serial if possible)
- Use like-for-like replacement cost, including installation
- Include ancillary costs: commissioning, calibration, software setup
- Consider “betterment” issues: older kit may only be replaceable with newer versions
If you have many items, insurers may accept a declared total with a schedule of key assets.
Choosing extensions that matter for electronics equipment
If you want cover that actually protects cashflow, consider these add-ons:
Business interruption (engineering BI)
Ask for:
- An indemnity period that matches realistic lead times (often 3–12 months)
- Increased cost of working
- Coverage for loss of gross profit, not just turnover
Temporary hire equipment
If you can rent a replacement unit (generators, chillers, test equipment), this can reduce downtime.
Deterioration of stock
If breakdown could affect temperature, humidity, or controlled processes, stock spoilage cover can be crucial.
Public utilities extension
If failure of incoming power causes damage, confirm whether it’s included.
Risk management: how to reduce breakdowns (and claim friction)
Insurers like well-run sites—and it often improves pricing and claim outcomes.
Key controls:
- Preventative maintenance: documented schedules, service reports, and remedial actions
- Power quality protection: surge protection, UPS maintenance, periodic battery testing
- Environmental control: temperature/humidity monitoring, clean filters, airflow management
- Spare parts strategy: critical spares (fans, PSUs, drives, boards) where lead times are long
- Alarm management: don’t silence recurring alerts without fixing root causes
- Change control: record modifications to systems and firmware updates
What insurers will ask (proposal and underwriting)
Be ready to provide:
- Equipment list and values
- Age of equipment and maintenance regime
- Site electrical protection (UPS, surge protection)
- Claims history and known issues
- Business interruption exposure (how long you can be down)
If you’re in electronics manufacturing or medical device production, insurers may also ask about:
- Cleanroom or controlled environment details
- Calibration and validation requirements
- Critical suppliers and lead times
Claims: what to do when equipment fails
A good claim is part speed, part evidence.
Steps that help:
- Make safe: isolate power, prevent further damage.
- Notify early: report the incident promptly.
- Document: photos, error logs, alarm history, and engineer notes.
- Keep failed parts: don’t dispose of boards/components until the insurer agrees.
- Track costs: parts, labour, freight, overtime, temporary hire.
- Downtime record: when production stopped, what was affected, and when you resumed.
If you have business interruption cover, keep a simple timeline and evidence of lost output or extra costs.
Practical examples (realistic scenarios)
- Server room UPS failure causes a hard shutdown and damages storage controllers. Machinery breakdown may cover repair/replacement; BI may cover lost revenue while systems are restored.
- PLC drive failure stops a production line. Cover may pay for the drive and associated damage; increased cost of working may fund overtime to catch up.
- HVAC control fault leads to overheating and damages sensitive test equipment. Engineering cover may respond where property insurance does not.
FAQs
Is machinery breakdown the same as warranty?
No. Warranty covers manufacturer defects under set terms. Machinery breakdown is insurance for sudden breakdown events, often after warranty ends or when the loss is wider than warranty scope.
Does it cover accidental damage?
Sometimes, depending on wording. Many engineering policies focus on breakdown rather than general accidental damage. Ask your broker to confirm.
Does it cover laptops and mobile devices?
Usually not under machinery breakdown. Those are typically covered under portable equipment or business contents sections.
Does it cover software and data?
Often limited. Data restoration may be capped or excluded. Cyber events are typically excluded.
Can I add business interruption?
Yes—often as an extension. For electronics-dependent businesses, it’s usually the most important add-on.
