A production stoppage lasting just one day, a server that will not reboot after a short circuit, or a construction site damaged by severe weather – incidents like these can bring business processes to a standstill. As dependence on complex technology and digital infrastructure grows, technical causes of downtime are becoming more likely – and they can hit mid‑sized companies harder than large corporates. Standard buildings and contents policies cover many of these technical risks only inadequately.
This is why more and more small and medium‑sized enterprises (SMEs) are looking at how to cover technical risks. Engineering insurance specifically covers damage to machinery, IT systems and photovoltaic installations, as well as losses during construction and installation phases.
- Standard buildings and contents policies usually do not cover operator error, short circuits or software faults.
- Engineering insurance closes these gaps for machinery, electronic equipment, photovoltaic systems and construction projects
- As technical complexity grows, the insurance needs of small and medium‑sized enterprises change.

Why engineering insurance matters for SMEs
While large corporates can cushion downtime through built-in redundancies, the same disruption often hits small and medium‑sized enterprises such as a craft business, a farm or a mid‑sized manufacturer directly – and without financial buffers.
Modern businesses are more dependent on technology than ever
Networked machinery, digital control systems, EPOS terminals, photovoltaic systems and charging infrastructure for vehicle fleets – technical dependence is growing in virtually every modern business. And with that increasing dependence comes greater vulnerability to technical failures.
Multiple causes of loss – not just fire and burglary
The causes of damage are varied: operator error, short circuits, power surges, vandalism or simply unforeseeable technical faults can put even well‑maintained equipment out of action.
Why traditional insurance cover is not enough
Standard buildings or contents policies often do not respond to such events. They typically insure perils such as fire, escape of water or burglary, among others – but not the operating error that damages a CNC machine, nor the software fault that deletes control data.
This is precisely where engineering insurance comes in. It is designed to address the risks that traditional policies do not generally cover.
Which types of engineering insurance help cushion downtime in SMEs
Engineering insurance is tailored to the specific risks associated with machinery, electronic equipment, renewable energy installations and construction and installation projects. Here is an overview of the main classes of cover for small and medium‑sized enterprises:
Machinery insurance protects fixed production plant against unforeseen damage – regardless of whether the cause is operator error or a technical fault. Business interruption cover, also known as loss of profits cover, can optionally be added to insure loss of revenue while repairs are carried out.
This policy provides protection specifically for mobile work equipment – for example in the construction, agricultural and forestry sectors. These high‑performance machines are often exposed to heavy wear and tear on site. Technical faults can also lead to losses. Contractors’ plant and machinery insurance covers both accidental damage and technical defects.
Electronic equipment insurance covers damage to IT systems, servers, EPOS terminals and other electronic installations. In view of ongoing digitalisation, this type of cover is relevant for almost every business – from medical practices with electronic patient records to trade businesses using digital job management systems. Data can also be included in the cover.
This cover is becoming increasingly important as solar installations become more widespread. Damage caused by storm, hail, snow load or technical faults can quickly become expensive – a risk many businesses underestimate. Business interruption cover, also called loss of revenue cover for PV systems, is often part of the cover concept. As an optional extension, reduced output of the photovoltaic system due to defective components or lower solar irradiation can also be insured.
Contract works insurance protects construction projects against damage during the build phase – for example as a result of severe weather or vandalism. It is particularly relevant for businesses that are constructing, altering or extending buildings: the existing structure can also be brought within the scope of cover.
Technical plant and structures are becoming ever more complex – and their installation correspondingly demanding. Despite the greatest care, damage due to design, material or installation faults cannot always be avoided. Such losses can be very costly for clients, manufacturers or installation firms. Erection all risks insurance provides cover for precisely these risks during the installation phase.
Comparison: sectors and typical technical loss scenarios
| Type of insurance | Protects against | Particularly relevant for | Optional: business interruption cover? |
|---|---|---|---|
| Machinery insurance | Operator error, technical faults affecting fixed machinery | Production, trades, manufacturing | Yes – covers loss of profits while repairs are carried out or until replacement |
| Contractors’ plant & machinery | Operator error/accidental damage to mobile work equipment (excavators, loaders etc.), technical faults | Construction, agriculture and forestry, transport and logistics, builders’ merchants | On request |
| Electronic equipment insurance | Damage to IT systems, servers, EPOS, electronic controls | All sectors with digital infrastructure (medical practices, offices, trade businesses) | Yes – covers loss of profits while repairs are carried out or until replacement |
| Photovoltaic insurance | Storm, hail, snow load, technical faults affecting solar installations | Businesses with rooftop or ground‑mounted solar systemsYes – covers loss of revenue while repairs are carried out or until replacement | Yes – covers loss of revenue while repairs are carried out or until replacement |
| Contract works insurance | Damage during the construction phase (severe weather, vandalism, theft) | Businesses with new build, alteration or extension projects | On request |
| Erection all risks insurance | Design, material and installation faults affecting technical plant | Installation and assembly firms, specialist trade businesses | On request |
Why are SMEs particularly exposed?
Small and medium‑sized enterprises face a structural dilemma: their dependence on individual machines or systems is often greater than that of large companies, yet their financial reserves tend to be smaller. SMEs are defined as enterprises with fewer than 250 employees and either an annual turnover of up to €50 million or a balance sheet total of up to €43 million (EU Commission definition).
A loss that a large corporate might simply record as an exceptional expense can bring a mid‑sized business to a standstill for weeks – or, in the worst case, lead to insolvency.
More complex infrastructure, more complex risk profile
Technical infrastructure is becoming increasingly complex. A business that operates a photovoltaic system with storage and charging points for electric vehicles, uses networked machinery and at the same time holds sensitive data has a risk profile that is no longer adequately covered by a standard property policy.
How engineering insurance policies differ in detail
- Causes of loss: Which events are covered? (operator error, material defects, unforeseen technical faults?)
- Negligence provisions: How is gross negligence treated? Will the insurer also pay if the business owner is negligent, or only if employees are at fault?
- Underinsurance: How are sums insured that are set too low dealt with? Are losses also reimbursed proportionately in the case of underinsurance?
- Emerging risks: Are emerging exposures, such as charging infrastructure for electric vehicles, IoT devices or networked control systems, included in the cover?
- Additional costs: Are clearance, decontamination and disposal costs insured at an adequate level? Depending on the type of loss, they can represent a considerable additional cost item and significantly increase the actual repair costs.
Engineering insurance as part of a wider risk management strategy
Engineering insurance is not a niche product; it plays an important role, especially in businesses with a high dependence on technology.
The market has evolved: many policies now also cover new risks such as photovoltaics, charging infrastructure and digital control data.
In many businesses, the question is whether their existing insurance cover is still keeping pace with their technical infrastructure – and whether all new risks are covered.
FAQ
Frequently asked questions
Engineering insurance is tailored to the specific risks associated with machinery, electronic equipment, renewable energy installations and construction and installation projects.
For manufacturing businesses, trades, agriculture, construction and installation firms, businesses with photovoltaic systems, and any company with significant IT and digital infrastructure (e.g. medical practices, offices, service providers).
Standard property policies mostly cover fire, escape of water or burglary. Typical technical losses – for example caused by operator error, short circuits, material faults or software problems – are generally not included and require dedicated engineering cover.
It complements engineering insurance and covers financial losses if a business is partially or completely at a standstill because of an insured loss – for example during repairs or until a machine is replaced.
Machinery insurance protects fixed production plant. Contractors’ plant and machinery insurance protects mobile work equipment, for example in construction, agriculture and forestry.
