Load Shedding, Power Surges and Insurance: What Homeowners Need to Know

Load shedding has changed the way South African households think about electricity. Many homes now use surge protection, inverters, batteries, generators or solar systems to reduce disruption when the power goes off.

But from an insurance perspective, it is important to understand that load shedding itself and damage caused by a power surge are not necessarily the same thing. That distinction can make a major difference when you need to claim.

Load shedding itself may not be the insured event

Load shedding is a planned interruption of electricity supply. By itself, the fact that the power was switched off does not necessarily mean there has been an insured loss.

The insurance question usually becomes more relevant when something happens as a result of the interruption or the restoration of power. Examples can include a power surge damaging appliances, electrical equipment failing when supply returns, freezer contents spoiling, an inverter or battery system being damaged, or a fire resulting from an electrical fault.

Whether the policy responds will depend on the wording, cause of loss and applicable exclusions or conditions.

Power surges are a different risk

A power surge is a sudden increase in electrical voltage. This can happen when electricity is restored, during grid instability, lightning events or other electrical disturbances.

Sensitive equipment can be particularly vulnerable, including televisions, computers, routers, refrigerators, freezers, alarm systems, gate motors, pool equipment, home automation systems, inverters and battery systems.

Some policies provide cover for electrical surge damage, while others may impose limits, excesses or specific requirements.

Surge protection can matter

Insurers may expect reasonable steps to be taken to protect electrical equipment. Depending on the policy and type of risk, surge protection may be recommended or required.

This can include plug-in surge protection, distribution-board surge protection, lightning protection, proper earthing and a correctly installed electrical system.

A surge protector is not a guarantee that equipment will never be damaged, but it can reduce the risk and may be important from an underwriting perspective.

Keep your electrical installation compliant

Electrical compliance becomes especially important when a home has been modified. This may include solar installations, inverters, battery backups, generator connections, additional distribution boards and EV chargers.

These systems should be installed correctly by suitably qualified professionals. Keep supporting documentation such as Certificates of Compliance, installer invoices, equipment specifications, warranty documents and photographs of the installation.

Solar and battery systems should be disclosed

A solar system is a major household investment. Panels, inverters and batteries can represent a significant portion of the value of the property.

If you install a solar or backup-power system, tell your broker or insurer. The installation may affect the building sum insured, electrical risk, fire exposure, theft exposure, replacement value and underwriting requirements.

Do not assume that adding a R200,000 solar system automatically increases the amount of cover on your policy.

Building cover or contents cover?

Where solar equipment is insured can depend on how it is installed and how the policy is structured. Permanently installed equipment may be treated as part of the building, while portable backup-power equipment may be treated differently.

This distinction can also apply to inverters, batteries, portable power stations, generators and charging equipment. Ask your broker which section of the policy covers each item.

What about appliances damaged by a surge?

If several appliances fail after a power event, insurers may ask for evidence of the cause. That could include a technician's report, repair quotation, damage assessment, proof of purchase, serial numbers and photographs.

Do not immediately dispose of damaged equipment unless instructed to do so. The insurer may need the item inspected before authorising replacement.

Food spoilage is not always automatically covered

A prolonged outage can cause food in a fridge or freezer to spoil. Some policies include limited cover for this type of loss, while others may not. There may also be a specific sub-limit.

If freezer contents are important to you, check whether your policy includes deterioration of refrigerated goods or similar cover.

Generator use introduces another risk

Generators can be extremely useful during power outages, but they should be installed and operated safely. From an insurance perspective, a permanently connected generator can change the electrical setup of the property.

Improper connections can create serious electrical and fire risks. If a generator has been permanently integrated into the home, make sure the installation is compliant and notify your insurer where required.

Inverters and batteries can affect fire exposure

Lithium battery systems have become common in homes. They are generally safe when properly installed and used according to manufacturer specifications.

Insurers may still want information about battery type, storage location, installer, ventilation, system size, fire protection and electrical compliance. The more substantial the installation, the more important proper disclosure becomes.

Replacement values can change quickly

Backup-power equipment can be expensive. If you have invested in solar, batteries or an inverter system, your building or contents value may need to be reviewed.

If the replacement value of the property has increased significantly but the sum insured has not, a future claim may be affected depending on the policy wording.

Not every electrical failure is a surge claim

Electrical equipment also fails because of wear and tear, age, mechanical breakdown, manufacturing defects and poor maintenance. Insurance is generally not designed to replace equipment simply because it reached the end of its useful life.

The cause of damage matters, which is why insurers may require a technician to determine whether the failure resulted from a covered electrical event.

Ask your broker these questions

Does my policy cover power-surge damage?

Is there a special excess or limit?

Are surge protectors required?

Is my solar system included in my building sum insured?

Where are my inverter and batteries covered?

Does my policy cover spoiled freezer contents?

Do I need to notify my insurer about backup-power equipment?

What documents should I keep for an electrical claim?

Load shedding may be part of everyday life, but the insurance risks around it can be complex. Understanding the difference between an outage, a surge, equipment failure and insured damage can help prevent surprises at claim stage.
