Nelson Gasfitting Services
Certified Gasfitting Services & Energy Transition Experts
When dealing with gas appliances, safety, precision, and full compliance are non-negotiable. We are fully certified gasfitters dedicated to keeping your home safe, energy-efficient, and future-proof.
Whether you require a new expert maintenance on existing gas systems or are preparing for New Zealand’s transition toward electric heat pump technology, we deliver industry-leading solutions tailored to your property.
Why You Must Choose Certified Gasfitters for Your Home
Gasfitting is tightly regulated in New Zealand. Fraser is a certified gasfitter registered with the Plumbers, Gasfitters, and Drainlayers Board (PGDB), so all work meets the rules.
Guaranteed Safety & Compliance:Every job includes a Gas Certificate of Compliance (CoC) proving it meets NZ safety standards.
Comprehensive Appliance Servicing: We service gas cylinders, hobs and boilers to keep appliances safe and efficient.
Protecting Your Home & Family: Professional installation prevents gas leaks, carbon monoxide exposure, and fire risk.
DIY Gasfitting is Unlawful & Unsafe in New Zealand
In New Zealand, DIY gasfitting is illegal and highly dangerous. Attempting to install, repair, or modify gas appliances yourself poses extreme safety risks, including fatal explosion, fire, and toxic carbon monoxide poisoning. Furthermore, uncertified gas work will immediately void your home insurance policy and leave you legally liable for damages. Never compromise on safety—always hire a PGDB-certified gasfitter like Chapmanz.
Navigating New Zealand’s Transition Away From Gas
As New Zealand shifts towards reducing fossil gas use, Chapmanz is here to help you move to cleaner and cheaper energy options.
We can replace legacy gas systems (LPG/Natural Gas hot water cylinders) at your home or business with high-efficiency hydronic heat pumps, delivering significant benefits:
Up to 50% Lower Water Heating Costs: Heat pump technology extracts heat from the surrounding air, requiring only a fraction of the electricity used by traditional systems or gas units.
Future-Proofed Energy Independence: Avoid rising gas connection fees, bottle delivery logistics, and anticipated fossil fuel price escalations.
Reduced Household Carbon Footprint: Significantly decrease your home's direct emissions by pairing heat pump water heaters, especially when paired with Solar Panels.
FAQs
Can I do any DIY gasfitting in New Zealand?
1
No. Under New Zealand law (Plumbers, Gasfitters, and Drainlayers Act 2006), it is illegal for unqualified persons to conduct gasfitting work. All installation, alteration, and repair of gas systems must be carried out by a PGDB-certified gasfitter to prevent serious hazards and maintain home insurance coverage.
Why is New Zealand moving away from gas energy?
2
New Zealand is working toward national climate targets and net-zero emissions. As part of this transition, fossil gas is being phased down in residential sectors in favour of energy-efficient, renewable electricity options like heat pumps, which drastically reduce carbon output.
How does replacing a gas hot water cylinder with an electric heat pump work?
3
Chapmanz handles the complete end-to-end replacement. Our team safely disconnects and caps your existing gas supply, removes the old cylinder, and installs a high-efficiency electric heat pump water heater with minimal disruption to your home's hot water supply.
How do bank Green Home Loans work for gas replacements?
4
Most major NZ banks (including ANZ, Westpac, ASB, and BNZ as of September 2026) offer low-interest (0% to 1%) home loan top-ups for eco-friendly home improvements. You can apply through your mortgage provider using a formal quote from Chapmanz for upgrading your gas system to a heat pump.
Yes. Heat pump water heaters are up to 3 to 4 times more efficient than traditional electric cylinders and significantly cheaper to operate than LPG or natural gas systems, especially when factoring in recurring gas fixed line fees or bottle delivery costs.
When Chapmanz completes any gasfitting work on your home, Fraser (a certified gasfitter) issues an official Gas Certification Code of Compliance. This documentation guarantees the work meets NZ safety standards and is lodged for insurance and council records.
