WHAT IS A TECHNICAL INSURANCE ASSESSMENT?
Objective findings that help claims move faster
A technical insurance assessment is an independent inspection of damaged equipment. It records what is damaged, tests why it failed (for example lightning, a grid-return surge, liquid, impact or ordinary wear and tear) and shows whether each item can be repaired economically or needs replacing, supported by current replacement pricing.
After a storm, a power return or an accident, insurers and loss adjusters rarely settle on a vague one-line quote. They look for serial-verified proof, an explanation of how the equipment failed, a clear line between sudden damage and gradual deterioration, and accurate like-for-like replacement specifications.
Highveld summer thunderstorms and load-shedding power returns are well-known causes of equipment failure in South Africa. Because we also work every day on IT support, networks and solar and backup power, our assessors test equipment with real diagnostic instruments rather than guessing from a photo.
We provide technical findings only. The insurer assesses cover and decides the claim, and legal questions should go to your attorney or broker.

STEP BY STEP
How Our Assessment Process Works
-
STEP 01
Log the instruction
The policyholder, broker or adjuster sends the claim reference, incident date and item list, and books a site visit or bench drop-off.
-
STEP 02
Inspect and test
We verify make, model and serial numbers, photograph the external and internal condition, and test power rails, boards, storage and surge paths.
-
STEP 03
Determine the likely cause
We assess whether the evidence points to lightning, a grid surge, liquid, impact, electrical overload or ordinary wear and tear.
-
STEP 04
Repair or replace
We check parts availability and costs against current like-for-like replacement pricing to show whether each item is repairable.
-
STEP 05
Report issued
You receive a signed PDF with photographs, findings and itemised repair or replacement quotes to submit to the insurer.
BEFORE YOU BOOK
What to Prepare for Your Assessment

QUESTIONS
Insurance Assessments FAQ
What is a technical insurance assessment report?
It is a written report by a technician that records the make, model and serial number of damaged equipment, what has failed internally, the likely cause of the damage (such as a power surge, lightning, liquid or impact) and whether the item can be economically repaired or should be replaced, with current market pricing.
Will my insurer accept your report?
Insurers decide what they accept. Our reports are written to include the information claims handlers and loss adjusters normally ask for: serial numbers, photographs, fault findings, likely cause, repair or replace reasoning and replacement quotes. If your insurer has specific requirements or a preferred assessor, tell us at the start and check with your broker.
Can you tell the difference between lightning, a power surge and normal wear and tear?
We inspect power supplies, surge components, circuit tracks, network transformers and integrated circuits. Surge damage and age-related failure usually leave different signs, but not every case is clear. Where the evidence is uncertain, the report says so rather than guessing.
Do you assess solar inverters, lithium batteries and backup power?
Yes. We assess hybrid and off-grid inverters, MPPT charge controllers, lithium battery packs and BMS boards, and UPS units, and we check whether surge protection and earthing were present. See our solar and backup power services.
How quickly do we get the report?
Bench assessments are typically completed within 24 to 48 business hours. On-site inspections are typically reported within 24 to 72 hours of the visit, depending on the number of items and how quickly supplier pricing arrives. We confirm the timeline when you instruct us.
Who pays for the assessment?
The party who instructs us pays our fee. Some policies contribute to reasonable assessment costs and some do not, so check your policy wording or ask your broker before you instruct us. Insurers, brokers and adjusters can be billed per instruction.
What does Beyond Economical Repair (BER) mean?
An item is described as BER when it cannot be repaired reliably, when parts are unavailable, or when repair would cost too much compared with replacing it. The exact threshold is set by the insurer or the policy terms, so we show the repair and replacement costs and let the insurer apply its own rules.
Do you work across all of KwaZulu-Natal?
Yes. Our workshop and head office are in Margate on the KZN South Coast, with on-site coverage from Port Edward and Port Shepstone through Durban, Ballito, Pietermaritzburg and the Midlands to Richards Bay and Zululand. Remote areas may carry a travel charge, quoted upfront.
Do you provide assessments in Gauteng?
Yes. We cover Johannesburg, Sandton, Midrand, Centurion, Pretoria, the East and West Rand and the Vaal through scheduled on-site visits, couriered bench assessments and remote file reviews for brokers and adjusters.
What about the data on a damaged server or laptop?
We test storage separately from the mainboard. If the drives survived, we can recover your data to replacement hardware under strict confidentiality and POPIA-aware safeguards, with your permission.
Can you also supply and install the replacement equipment?
Yes, if you ask us to, and we will be open about that. Our fee for the assessment does not depend on who supplies the replacement. If your insurer prefers a strict separation between assessor and supplier, we can assess only.
Do you give legal advice or decide the claim?
No. We provide technical findings only. The insurer assesses cover and decides the claim, and legal questions should go to your attorney or broker.
