The Service
Urgent generator breakdown and callout assistance
A generator that fails during an outage never picks its moment, so we do not keep office hours for breakdowns. Call or WhatsApp 082 057 4605 any time, day or night, and a technician arrives within 1 hour across our Gauteng service area.
We start with a diagnosis at the generator. The fault might be in the engine, the alternator, the fuel system, the control panel or the electrical connections, so we test before we decide, and we tell you in plain language what failed.
Emergency work covers diesel standby sets at homes, businesses and industrial sites, as well as petrol and gas generators. We service and repair the brands listed on our brands page.
Before a repair begins you get a written quote. If more work is found, we explain it and quote it first. The diagnosis is included at no extra charge when you go ahead with the repair, and our workmanship is guaranteed for 1 year.
The callout is R400 to R700 in business hours and R700 to R1,400 after hours. The callout fee is only payable if you do not accept the quotation. If you accept the quotation, the callout fee is waived. A breakdown at a shop, a factory or a home gets the same response.

How It Works
How an emergency visit is booked
- 01
Send your location and generator details
Call, WhatsApp or use the form. Give the suburb in Gauteng, the make, model and kVA if you know them, the fuel type, and what the generator is doing or which alarm it shows. A photo of the data plate on WhatsApp helps.
- 02
We review the enquiry
The details are checked to decide whether the problem needs a site visit, what kind of visit it is, and whether parts may be needed.
- 03
A technician comes to you
Open 24 hours a day, 7 days a week, including weekends and public holidays. For breakdowns and emergencies we arrive within 1 hour. Servicing and maintenance visits are booked for a time that suits you.
- 04
Charges are explained first
The callout fee is R400 – R700 in business hours and R700 – R1,400 after hours. The callout fee is only payable if the customer does not accept the quotation. If the quotation is accepted, the callout fee is waived. The written quote is free, and the diagnosis is included at no extra charge when you go ahead with the repair.
- 05
Diagnosis, then a quote
The generator is inspected and the fault is tested on site. A written quote is given before work starts and is valid for 14 days. If more work is found once the job is under way, it is explained and not done without your approval.
- 06
Work follows the accepted quote
Repairs or servicing go ahead on the scope you accept. Payment is due on completion unless a credit account or another arrangement is agreed in writing. EFT bank transfer and cash are accepted.
Common Fault Types
What we are usually called out for
01
Generator fails to start
Flat starter battery, faulty solenoid, flooded engine, low oil shutdown, control board fault — we diagnose and repair the root cause on-site.
02
Generator starts but trips off
Overload conditions, coolant temperature faults, low oil pressure, AVR failure, or governor problems causing shutdown under load.
03
No output voltage
AVR failure, excitation winding faults, or control panel issues resulting in a running generator that produces no usable power.
04
Fuel system failure
Blocked fuel filters, contaminated diesel, failed lift pump, or air in the fuel system preventing the engine from sustaining operation.
05
Control panel fault codes
AMF and ATS controller faults including sensor alarms, communication errors, and configuration issues preventing automatic operation.
06
Overheating & coolant faults
Blocked radiators, coolant leaks, failed thermostats, and low coolant levels causing high-temperature shutdowns under load.
What to Expect
Honest Diagnosis. No Surprises.
When our technician arrives, the first step is a diagnostic assessment. We do not quote before we understand the fault, so the price you approve is based on what is actually wrong, not a guess.
Once you approve the quote, we start the repair and keep you informed. Before we leave, we run the generator and check its output so you know it is ready for the next outage. To stop the next one, see standby and emergency generator maintenance.
If a part has to be ordered, we tell you before ordering it and explain what happens in the meantime.

Common Questions
Emergency generator repair questions
Can I book an urgent generator callout?
Yes, any time. Call or WhatsApp 082 057 4605 with the suburb and what the generator is doing. We are open 24/7 and arrive within 1 hour.
What should I say when the generator is down?
Whether it cranks, whether it fires, whether any voltage appears, and any alarm on the controller. A photo of the plate helps. Unknown answers can be left blank.
Should I keep resetting a shutdown alarm?
No, if the alarm is low oil pressure or high temperature. Those can be real protection events. Repeated resets can damage the engine. Stop and book a diagnosis.
Do urgent visits cover diesel and petrol sets?
Yes. Say which fuel it is. A diesel that cranks and will not fire is a different job from a petrol set with stale fuel.
Can you attend businesses and homes?
Yes. Commercial standby sets and smaller home generators are both attended across Gauteng. Tell us about access, such as estate security or a locked plant room, so the technician can get straight to the set.
What if the engine runs and the building is still dark?
That is often a breaker, AVR or transfer fault rather than another start attempt. Leave the set stopped if you are unsure, and describe that pattern when you call.
Still unsure what the fault is? Call or WhatsApp 082 057 4605 for onsite diagnosis.
