Gas boiler and geyser repair: prices and what to check in South Africa

Updated 4 November 2026

Gas boiler and geyser repair in South Africa usually costs between R 850 and R 3,500, depending on the part and on whether a compliance certificate is needed. The quickest way to see current prices for your city is to describe the fault in a request on BlaBlaPrice.

These figures come from geyser repair listings, and gas units have different parts, so ask for a quote for your own fault rather than relying on the table alone.

Rules and what to check before you book

Gas work should be done by an installer registered with SAQCC Gas, and you should ask for a certificate of compliance (CoC) once the repair is finished. Some gas businesses sell repair and CoC work together, so ask whether the inspection is included in the repair price. Permit fees are set by each municipality and can depend on the value of the work, so check with your city before a larger job.

Winter demand and the best time to book

Winter runs from June to August, and hot water and heating are used most then, so faults show up quickly and appointments fill faster. Summer runs from December to February. For a planned service, book in late summer or early autumn, from February to April, so the unit is checked before the cold arrives.

How the work is priced and delivered here

Repairs are priced by the part, as the table shows, and a geyser's size is given in litres. Gas units are also rated in litres per minute, for example 16 litres per minute for one common model, so give the size and make from the label. Visits are available in Johannesburg, Cape Town, Durban, Pretoria and Gqeberha. Name your city and suburb so the seller can plan the route and the date.

What to put in your request

Name the device type, the make and model, and the fault, for example no hot water or a pilot light that will not stay lit. Add the boiler type, how old the appliance is, your area, and when you can be home. Say whether you need a repair warranty and a compliance certificate, and give your budget. If you smell gas, turn off the supply and leave the building before you book anything.
