Are you registered and certified?
Yes. We're registered with SAQCC Gas (Registration No. 3545) and comply fully with SANS 10087-1 standards. You can verify our registration on the official SAQCC website. We always recommend customers verify any gas installer's credentials before booking work.
Why should I choose gas over electricity?
Gas offers several advantages: it works during load shedding, heats instantly with precise temperature control, and is often more cost-effective to run. Professional chefs prefer gas for its immediate response. For water heating, gas geysers provide hot water on demand without storing large volumes of heated water.
Is gas safe to use in my home?
When installed correctly by a registered professional, gas is very safe. Modern gas appliances have built-in safety features like flame failure devices that automatically shut off gas if the flame goes out. The key is proper installation, adequate ventilation, and regular maintenance – all of which we provide.

Gas Installations
What gas appliances can you install?
We install all LP gas appliances including gas hobs, stoves, ovens, geysers (water heaters), braais, fireplaces, patio heaters, pool heaters, and space heaters. Whether it's a single hob or a full property with multiple gas points, we handle it.
What's included in a gas installation?
Our installations include all necessary materials (piping, fittings, regulators, shut-off valves), labour, pressure testing, and a Certificate of Compliance (COC). We'll discuss your specific requirements and provide a detailed quote before starting any work.
What's the difference between internal and external installation?
An external installation places the gas cylinder outside your home with piping running through the wall to your appliance – this is often preferred for safety and aesthetics. An internal installation keeps the cylinder inside (typically in a cupboard) and is used when external placement isn't possible. Both require proper ventilation.
Can I install gas in an apartment or townhouse?
Yes, gas can be installed in apartments, townhouses, and sectional title properties. Internal installations are common in these settings. You may need body corporate approval – we can advise on the process and provide documentation to support your application.
How long does a gas installation take?
A standard single-appliance installation typically takes 2-4 hours. More complex installations with multiple appliances or longer pipe runs may take longer. We'll provide a time estimate when we quote.
Do I need to buy my own gas appliance?
You can purchase your appliance from any retailer, and we'll install it. Alternatively, we stock a range of quality gas geysers, hobs, and accessories if you'd prefer to purchase through us.
Do you install natural gas (piped gas) appliances?
No, we specialise in LP gas installations only. Natural gas (piped municipal gas) requires different equipment and certifications. If you have a natural gas supply, you'll need to find a practitioner who specifically works with NG systems.
Gas Geysers & Water Heaters
How does a gas geyser work?
A gas geyser (also called an instant or tankless water heater) heats water on demand as it flows through the unit. When you open a hot tap, cold water enters the geyser, triggers the burner, and hot water flows out within seconds. There's no storage tank, so you're not paying to keep water hot 24/7.
What size gas geyser do I need?
Size depends on your usage. A 5-8L unit suits a single point like a kitchen sink or shower. A 12-16L unit can supply 1-2 bathrooms simultaneously. A 20L+ unit is ideal for larger homes with multiple bathrooms. We'll assess your needs and recommend the right size.
Will a gas geyser work with low water pressure?
Standard gas geysers need reasonable water pressure to operate. However, we stock low-pressure (Eco-Flow) models specifically designed for areas with poor municipal pressure or gravity-fed systems. These work reliably even with minimal water pressure.
What's the difference between battery and 220V gas geysers?
Battery-operated units use D-cell batteries for ignition – they're completely off-grid and work during power outages. 220V units plug into mains power for the ignition, display, and fan (on forced-draught models). 220V units are more feature-rich but require electricity to operate.
Can a gas geyser be installed indoors?
Yes, but it depends on the geyser type. Type B (indoor with flue) and Type C (room-sealed/fan-forced) units are designed for indoor installation. Proper ventilation and flue installation are essential. Type D units are outdoor-only and must be installed under a cover.
How long does a gas cylinder last for a geyser?
It varies by household usage. A 9kg cylinder typically lasts 2-4 weeks for a family of four using a gas geyser for showers. A 19kg or 48kg cylinder lasts proportionally longer. External installations can accommodate larger cylinders for fewer refill trips.
Do you repair gas geysers?
Yes, we diagnose and repair all major gas geyser brands. Common issues include ignition problems, flow sensor faults, temperature fluctuations, and gas valve issues. We carry common spare parts and can often repair on the first visit.
Safety & Compliance
What is a Certificate of Compliance (COC)?
A COC is a legal document issued by a registered gas practitioner confirming that a gas installation meets South African safety standards (SANS 10087-1). It's required by law for all gas installations and is essential for insurance claims and property sales. Every installation we complete includes a COC.
Do I need a COC for my gas installation?
Yes. South African law requires a valid COC for all gas installations. Without one, your insurance may not cover gas-related incidents, and you'll need one when selling your property. If you have an existing installation without a COC, we can inspect and certify it.
How do I verify if a gas installer is registered?
All legitimate gas installers must be registered with SAQCC Gas. You can verify any installer's registration on the SAQCC website. Our registration number is 3545 – we encourage you to verify before booking.
What safety features do gas appliances have?
Modern gas appliances include multiple safety features: flame failure devices (cuts gas if flame goes out), oxygen depletion sensors (shuts off if oxygen levels drop), overheat protection, and pressure relief valves. Combined with professional installation, these make gas very safe.
Do I need a gas cage for my cylinders?
Gas cages are recommended for outdoor cylinder storage to prevent theft and accidental damage. For installations exceeding 100kg of gas (about 2x 48kg cylinders), fire department approval and proper cage installation may be required. We supply and install compliant gas cages.
How often should gas installations be inspected?
Gas installations should be inspected at intervals not exceeding 5 years per SANS regulations. Pigtails older than 5 years must be replaced. We also recommend checking your system if you notice any changes in appliance performance or suspect a leak.
Repairs & Gas Leaks
What should I do if I smell gas?
Stay calm and act quickly: Close the cylinder valve (turn clockwise). Don't operate electrical switches, appliances or phones near the area. Open doors and windows to ventilate. Keep people clear and move upwind. If there's a fire or strong gas smell you can't control, call the fire service from a safe location. Once safe, contact a registered gas installer for an inspection before using the system again.
How do I know if I have a gas leak?
Signs of a gas leak include: a rotten egg smell (mercaptan is added to LP gas for detection), hissing sounds near gas lines or cylinders, your gas cylinder emptying faster than usual, yellow or orange flames instead of blue, or unexplained physical symptoms like headaches indoors.
Why is my gas cylinder running out so fast?
If your gas usage has suddenly increased without explanation, you likely have a leak somewhere in the system. Common culprits include worn hoses, loose connections, faulty regulators, or leaks at appliance connections. We can perform leak detection to find and fix the problem.
Can I fix a gas leak myself?
No. Gas leak repairs must be done by a registered gas practitioner. DIY repairs are dangerous, illegal, and will void your insurance. Professional repairs include proper pressure testing and a COC to confirm the system is safe.
What gas geyser problems can you repair?
We repair most gas geyser issues including: ignition failures, pilot light problems, temperature fluctuations, water not heating, unit shutting off unexpectedly, strange noises, flow sensor issues, and gas valve problems. We service all major brands.
Do you offer emergency repair services?
Yes, we provide emergency callout services for gas leaks and urgent repairs. Gas leaks are prioritised as safety concerns. Contact us and we'll arrange the fastest possible response.
Products & Equipment
Do you sell gas appliances?
Yes, we stock a range of gas geysers, hobs, and accessories from trusted brands like Dewhot, Atlas, and Chad-O-Chef. You can browse our products online or contact us for recommendations based on your specific needs.
Can I buy gas refills from you?
Yes, we offer LP gas refills with delivery in 9kg, 14kg, 19kg, and 48kg cylinder sizes. We operate a cylinder swap system – we deliver a full cylinder and collect your empty one.
What's included when I buy a gas geyser from you?
When you purchase a gas geyser from us, we can include professional installation with all necessary materials and a COC. This ensures your unit is set up correctly and safely from day one.
Do you sell spare parts and accessories?
Yes, we stock common gas installation components including regulators, hoses, pigtails, fittings, and replacement parts for gas geysers. If we don't have something in stock, we can usually source it.
What's the difference between Dewhot geyser types?
Eco-Flow (Low Pressure) models work with low water pressure and gravity-fed systems. Diaphragm Activated models are reliable, low-maintenance units for standard pressure. Constant Temperature models maintain precise water temperature and suit multiple outlets. Fan Forced models are high-efficiency units with powered ventilation.
Pricing & Payments
How much does a gas installation cost?
Pricing depends on the type of installation, pipe run length, and specific requirements. Basic internal hob installations start from around R2,000, while external installations with longer pipe runs start from around R2,950. We provide detailed quotes upfront with no hidden costs.
Do you charge for quotes?
No, we don't charge for quotes. For more complex installations, we prefer to do a site visit so we can assess the job properly and explain everything to you in person.
What payment methods do you accept?
We accept EFT, cash, and card payments. Payment terms are discussed when booking and confirmed in your quote.
Are there any hidden costs?
No. We provide transparent, itemised quotes. The price we quote is the price you pay. If anything changes during the installation (for example, if we discover additional work is needed), we'll discuss it with you before proceeding.
How much does a COC cost on its own?
If you have an existing gas installation that needs certification, COC inspections start from R950. This includes a full safety inspection, pressure testing, and the certificate if everything passes. If repairs are needed, we'll quote separately.

Technical LP Gas FAQ
SANS 10087-1:2024 compliant answers for LP gas cylinders, distances, ventilation and regulations in South Africa.
Certificates, Legal & Selling Property
Do I need a gas Certificate of Conformity (CoC) for an LP gas installation?
Yes. All fixed LP gas installations in South Africa require a Gas CoC issued by a registered SAQCC Gas practitioner after inspection and testing.
Is a gas CoC required when I sell my house or commercial property?
Yes. On sale/transfer you need a valid gas CoC for the installation. South Africa uses the SAQCC digital CoC format.
Can I install a gas stove or gas geyser myself and get a CoC later?
No. Only a registered gas practitioner may install, commission and issue a CoC for fixed gas installations.
How long is a gas CoC valid?
It remains valid while the installation and property owner is unchanged, safe and compliant. If the system is altered, falls out of compliance or the installation is now 5 years old, a new CoC is required.
LP Gas Cylinders Outdoors - Distances & Enclosures
What are the minimum safety distances for outdoor LP gas cylinders?
1-2-3 rule: at least 1m to openings below valve height (doors, low windows, airbricks); 2m to drains/manholes/forced-draught inlets; 3m to openings directly above (or fit a compliant non-combustible canopy to reduce). Additional rules do apply.
How far from a boundary wall must LP gas cylinders be?
Up to two cylinders: at least 1m (or tight to a compliant firewall). More than two cylinders: at least 3m (or along/around a firewall by at least 3m).
Can LP gas cylinders be placed against any wall?
Gas cylinders installed on a boundary wall must have a 30-minute fire-resistance rating. Cylinders may be installed on a single-brick wall only if it is a divider wall and not a boundary wall.
What about thatched roofs or an electric fence above the wall?
Thatched eaves: keep cylinders at least 5m away (or at least 3m with a compliant firewall). Electric fence above the wall: fit a non-combustible canopy so the safe path to the fence is at least 1.5m.
Do outdoor LP gas cylinders have to be in a cage (enclosure)?
Yes in most public-access locations. Exception: H3/H4 homes with an exclusive private yard and no public access. Enclosures need top & low-level ventilation and clear access to close valves.
What ventilation is required for a typical two-cylinder cage?
Provide high-level free area plus low-level openings: at least 60cm² per side and 60cm² per cylinder on the front, as low as possible.
Can I install LP gas cylinders under a balcony or inside a recess?
Only if the recess/structure complies (clearances, ventilation and canopy rules). Avoid enclosing cylinders unless built per the enclosure clauses.
Indoors, Flats & Cupboards
How much LP gas is allowed inside a flat or house in South Africa?
Flats/clusters over 2 storeys (H3): 9kg per unit. Clusters/townhouses/semis up to 2 storeys (H3): 19kg per unit. Dwelling houses (H4): 19kg per house. Balconies and attached garages are included in these limits.
Can I keep an LP gas cylinder in a kitchen cupboard?
Yes - one 9kg cylinder per cupboard, no electrical points in that section, nothing else stored there, and permanent ventilation (e.g., at least 60cm² low and at least 60cm² high on door/side, or vented outside).
If not in a cupboard, where should an indoor LP gas cylinder go?
Place it as close as possible to a door that leads outside, with low-level permanent ventilation (e.g., airbricks near the floor or a 6mm or larger external door gap).
Can I manifold multiple cylinders or use a changeover valve indoors?
No. Manifolds and changeovers must be outdoors.
Are LP gas cylinders allowed in garages, basements or below ground?
No. Garages, basements/cellars and below-ground positions are prohibited. Never place cylinders above an appliance.
Appliance Clearances, Electrical & Ventilation
How close may an indoor LP gas cylinder be to a gas hob or other heat source?
Keep at least 300mm from a gas hob; at least 2m from other fuel heat sources (can reduce to 1m with a compliant non-combustible heat shield).
How close may electrical switches and sockets be to burners and cylinders?
At the appliance: switches/sockets at least 200mm horizontally from the nearest burner (or at least 1.5m high). At cylinders outside: keep electrical equipment out of the prohibited ignition zone of 3m below cylinder valve and 1.5m above cylinder valve.
What ventilation do kitchens, flueless heaters and gas geysers need?
Kitchens may need permanent high/low ventilation depending on appliance input. Flueless space heaters and certain gas water heaters require permanent ventilation and are restricted from some rooms. We size vents during a site survey.
Regulators, Pipework & Materials
Which regulator pressure is used for typical domestic LP gas appliances?
Domestic appliances use low-pressure LP gas regulators matched to the appliance. We set and test during commissioning.
Can gas pipework run through walls or outside?
Yes, if correctly routed, protected/sleeved where required, supported and pressure-tested. We follow SANS construction and material rules.
Can LP gas flexible hoses be used permanently?
Use approved LPG hoses within length limits and replace when aged/damaged. We check dates and condition during service.
Maintenance, Testing & Safety
How often should my gas installation be inspected?
At intervals not exceeding 5 years. Manifolds are on a planned 5-year cycle; pigtails older than 5 years must be replaced.
What testing happens before a CoC is issued?
We inspect workmanship and components, pressure-test stages, verify operating pressures, commission the appliances and then issue the digital CoC.
Can LP gas cylinders be in direct sunlight or rain?
Yes. Cylinders are designed for outdoor conditions. Place them on a level, non-combustible base, protect from tampering/vehicle damage and fit a compliant canopy or cage if required.
I smell gas - what should I do?
If you suspect a gas leak: immediately close the cylinder or main shut-off valves. Extinguish open flames only if safe. Do not operate electrical switches or appliances, and avoid using phones near the area. Keep people clear and move upwind. Ventilate by opening doors and windows if safe. If there's a fire, a strong smell of gas, or the situation isn't under control, call the fire service from a safe location. Once safe, arrange an inspection by a registered gas installer before restoring use.
How can I check how much gas is left in my cylinder?
Weigh it: Full mass = tare weight (stamped "TW") + gas contents. Example: TW 10.5kg + 9.0kg = 19.5kg when full.
Warm water test: Pour warm (not boiling) water down the side, wait a few seconds, then run your hand down the metal. It feels warm above the liquid level and cool below, giving an approximate fill level.
Which cylinder size is best for a gas hob, braai or geyser?
Hobs often pair with 9kg (indoors cupboard) or 19kg (outdoors). Gas braais/geysers typically use 19kg or 48kg outdoors. We size to your demand and SANS limits.
Are composite LP gas cylinders allowed?
Yes if approved and correctly installed/secured; clearances and enclosure rules still apply.
Can LP gas cylinders go on an apartment balcony?
Yes within the H3 per-unit limits; the balcony counts as part of the unit. Clearances and ventilation still apply.
Do insurers require a gas CoC?
Most insurers expect a valid gas CoC for claims related to gas installations. Keep your digital CoC handy.
