A geyser replacement is one of the most common and most expensive household plumbing jobs in South Africa. Here is a detailed breakdown of what it costs in 2024–2025 — and what you are paying for.

What is included in the installed price?
A full geyser replacement typically includes:
- Draining and disconnecting the old unit
- Supply and installation of the new geyser
- New pressure control valve (PCV) and T&P relief valve (if not already compliant)
- New drip tray (required by SANS 10252 for ceiling-mounted geysers)
- Insulating the first metre of pipe (required)
- Testing and commissioning
- Plumbing compliance certificate (mandatory under SANS 10252)
Items that may be quoted separately: geyser blanket insulation, thermostat upgrade, replacement of aged supply piping, or structural support for a heavier solar unit.
Why is a plumbing compliance certificate required?
Since 2009, any new or replacement geyser installation in South Africa must be signed off by a registered plumber and a plumbing compliance certificate issued. This is a legal requirement under SANS 10252. Without it, your home insurance may not cover a geyser-related water damage claim. Only use a PIRB-registered plumber for geyser installations — ask to see their registration. TruePro verifies PIRB/IOPSA registration and shows a badge on the plumber's quotes and profile once confirmed.
Which type of geyser should you choose?
- Standard electric: lowest upfront cost, highest running cost. Makes sense if budget is tight or the installation is in a difficult location.
- Solar: higher upfront cost but low running cost in a sunny climate. Payback period is typically 4–7 years. Requires roof space and suitable orientation.
- Gas: instant hot water, no tank storage losses, works during loadshedding. Requires a gas connection and certification — PIRB gas registration required for the installer.
- Heat pump: uses ambient heat from the air to heat water — 3–4× more efficient than a standard element. Significant energy saving with moderate upfront cost. Recommended for households in mild-to-warm climates.
Tips for getting a fair price
- Get quotes that specify the geyser brand and model — not just "150 L electric geyser." Kwikot, Kwikhot, and Ariston are common brands in South Africa; quality varies.
- Confirm the plumbing compliance certificate is included. If it is not, walk away — the work is not legally compliant without it.
- Check whether your home insurance will pay out for the old geyser damage (most home insurance policies cover geyser failure). The insurance payout may cover the replacement cost.
- Ask about labour guarantees. Most reputable plumbers offer 12 months on the installation workmanship; the geyser unit itself carries the manufacturer's warranty.
- Avoid paying the full amount upfront. TruePro's payment protection holds your payment securely until you've confirmed the installation is complete and the compliance certificate has been issued.
