Pricing Factors
What Determines the Final Cost of Your Generator Repair?
Generator size & kVA rating
Larger generators require more materials, more oil, larger filters and longer labour time. A 10kVA residential unit costs significantly less to service than a 500kVA industrial standby system.
Brand & model
Premium brands such as Cummins, Caterpillar and Perkins use quality OEM parts that carry a cost premium. Generic Chinese-built generators often have cheaper parts but sourcing them can be slow.
Parts availability
Common parts are stocked on our vehicles and available immediately. Rare or imported components may need to be ordered — we communicate lead times clearly before work begins.
Repair complexity
Most repairs are completed on-site on the first visit. Some major faults — alternator rewinds, full engine rebuilds — require workshop time and specialist equipment.
OEM vs quality aftermarket
We offer both OEM and quality aftermarket parts depending on your preference and budget. We recommend OEM for critical components and quality aftermarket for serviceable items.
Emergency vs planned work
Emergency after-hours callouts carry a higher callout fee than scheduled service appointments. A maintenance contract reduces your emergency risk and often includes discounted callout rates.
Pricing FAQ
Common Cost Questions
Straight answers on pricing, quoting and what to expect when you call us.
How much does a basic generator service cost in South Africa in 2026?
A basic generator service including oil change, filter replacement and inspection costs between R900 and R1,800 depending on generator size and oil specification required. Larger diesel generators cost more than small petrol units due to oil volume and filter pricing.
What does it cost to repair a generator that will not start?
Diagnosing and repairing starting failures typically costs R600–R3,500. This covers battery testing and replacement, starter motor inspection, fuel system checks, glow plug or spark plug replacement, and control panel fault diagnosis.
How much does AVR replacement cost in Gauteng?
AVR (Automatic Voltage Regulator) replacement costs R2,200–R9,000 depending on the generator brand and AVR type. OEM parts cost more than quality aftermarket alternatives. We source the correct match for your unit and test voltage stability under load before sign-off.
Is it worth repairing an old generator or should I replace it?
As a rule of thumb, if the repair cost exceeds 50–60% of the replacement value of an equivalent unit, replacement is usually the better long-term investment. For generators under 10 years old in otherwise good condition, repair is almost always the better option.
Are there hidden callout fees?
No. We provide a clear written assessment of the fault and repair cost before any work begins. Standard callout fees apply for the visit, and the diagnostic assessment is included in the repair cost — you are not charged twice.
