Should Your Welder Be Insured? What NZ Homeowners Need to Know

Why insurance matters when hiring a welder

A welder is often working with heat, sparks, gas, grinders, heavy steel, and sometimes work at height or near finished surfaces. Even on a small residential job, there’s scope for things to go wrong — from scorch marks and fire damage to injury, property damage, or an unfinished job after a tool or vehicle accident.

For New Zealand homeowners, a welder’s insurance is not just a nice-to-have. It can be a practical sign that the tradesperson runs a proper business and is prepared to stand behind their work.

Insurance won’t guarantee a perfect result, but it can help protect you if:

• your driveway, fence, windows, or landscaping are damaged
• a spark or grinding disc causes a fire or melt damage
• someone is injured on your property
• the tradesperson’s gear is stolen or broken and the job is delayed
• the welder has to return to site to fix a workmanship issue

The main types of insurance a welder should consider

Not every welding business will hold the same policies, but these are the most relevant cover types to ask about.

Public liability insurance: the key one to ask about

If you only check one policy, make it public liability.

This is the cover most often relevant to homeowners because it can respond when the welder accidentally causes damage to someone else’s property or injury to a third party. Examples include:

• sparks damaging cladding, roofing, decking, or painted surfaces
• heat distortion or burn-through affecting nearby materials
• a gas bottle or machine toppling and damaging a vehicle or window
• an unsecured work area causing a visitor to trip

Public liability is not the same as workmanship quality or a guarantee against defects. It’s there for accidental damage and third-party claims, not for poor business decisions or deliberate shortcuts.

Contract works insurance: useful on bigger jobs

If the welder is fabricating and installing a new gate, balustrade, structural steel element, or custom outdoor feature, contract works insurance can be useful. It may cover accidental damage to the work in progress, materials on site, or parts of the job before handover.

This matters on sites where materials are expensive or the job is staged over several visits. Ask whether the policy applies to:

• materials stored on your property
• items in transit to your home
• partially completed work awaiting installation
• subcontracted work, if any

Tool and equipment cover: less relevant to you, but still important

Tool insurance doesn’t directly protect you as the homeowner in the same way public liability does, but it can affect the job outcome. Welding gear, grinders, extension leads, leads, helmets, gas gear, and portable machinery are expensive and sometimes targeted by thieves.

If a tradesperson loses their kit and can’t finish the job on time, you could be left waiting. A business that is properly insured is often better able to recover from setbacks and keep the job moving.

What insurance does not replace

Insurance is only one part of checking a welder. It does not replace:

• suitable experience with the type of job you need
• proper safety practices and site protection
• clear written quotes and scope of work
• checking references or photos of past jobs
• permits, council consent, or other approvals where needed

In New Zealand, some welding work is part of a wider project that may trigger other rules. For example:

• building work may need a building consent from your local council
• structural work should be done to the right standard and may need sign-off or producer statements depending on the project
• electrical work must be carried out by an appropriately licensed electrician, not a welder, unless the work is outside electrical scope
• plumbing, gasfitting, and drainlaying are restricted work and require the right registration and licensing under the PGDB system

If your welding job touches any of those areas, make sure the right licensed tradespeople are engaged as well.

How insurance protects the homeowner in practice

Good cover can make a stressful situation more manageable. Here’s how it may help in real life.

Example: accidental damage to your property

A welder is installing a steel gate and a grinder sparks a nearby painted timber fence, causing scorch marks and requiring repainting. Public liability insurance may help cover the repair cost, subject to the policy terms and excess.

Example: fire or heat damage

Hot work near a deck or cladding can create fire risk. If an accidental fire damages your outdoor area, insurance may provide a pathway to compensation without a long dispute over who pays.

Example: injury to a visitor or neighbour

If someone is injured because of the work area — for instance, from a falling piece of metal or equipment left in a walkway — liability cover can be important.

Example: unfinished work after equipment theft

If the welder’s gear is stolen from a work vehicle, tool cover may help them replace it and get back to your job more quickly.

Remember: you still need your own home and contents insurance. A tradesperson’s policy usually does not replace your household cover, and your insurer may still need to know if a claim arises.

How to confirm a welder is insured

Don’t assume a business is covered just because it sounds professional. Ask for evidence before work starts — especially for outdoor jobs, structural installations, or anything involving heat near finished surfaces.

Ask for these details in writing

Request:

• the type of insurance held
• the insurer’s name
• the policy number
• the amount of cover per claim and in total
• the expiry date
• whether the cover includes hot work, subcontractors, and work at residential properties

A simple email reply or a current certificate of insurance is usually enough to start with. For larger or higher-risk jobs, ask for the certificate to be current and specific to the business trading name you’re dealing with.

Check the certificate carefully

Make sure:

• the business name matches the quote or invoice name
• the policy is active for the dates of your job
• the cover limit is appropriate for the value of the potential damage
• exclusions do not rule out the type of work you’re hiring for

A low cover limit can be a red flag on larger jobs. For example, if a welder is working near expensive cladding, glazing, or landscaping, a very small public liability policy may not be enough.

Ask who is actually doing the work

If the business uses subcontractors, confirm whether they are covered under the policy or need their own insurance. This is especially important where the job involves multiple trades or staged work.

Other credentials to check alongside insurance

Insurance is only one part of hiring safely. For a welder, also check:

• experience with residential work, not just workshops or industrial fabrication
• photos of similar jobs, such as gates, handrails, fencing, or structural steel
• references from recent clients
• whether they provide written quotes with clear inclusions and exclusions
• whether they can explain how they will protect your property from sparks, heat, and debris
• whether they know when council consent or other approvals may be required

If the job involves stairs, balustrades, retaining features, structural posts, or anything that affects the building structure, ask how they’ll coordinate with a builder or engineer if needed.

Questions to ask before you hire

Use these practical questions when getting multiple quotes:

• Do you hold current public liability insurance?
• What is your cover limit?
• Does your policy cover hot work at residential properties?
• Are your tools and equipment insured?
• Do you use subcontractors, and are they insured too?
• Can you provide a current certificate of insurance?
• Have you done similar jobs in NZ homes before?
• Will the quote clearly state what you will protect and what site preparation is required?

A confident, well-organised tradesperson should be comfortable answering these questions. If someone seems evasive or says insurance is “not necessary”, treat that as a warning sign.

What if the welder says they’re not insured?

You can technically choose to hire an uninsured tradesperson, but you are taking on more risk.

If anything goes wrong, your options may be limited and disputes can become costly and time-consuming. For a small repair, some homeowners are tempted to save money by hiring on price alone. But if there’s a fire, damage to finished surfaces, or an injury, the savings can disappear quickly.

As a rule of thumb:

• get at least two or three written quotes
• compare not just price, but insurance, experience, and scope
• avoid cash-only arrangements with no paperwork
• don’t let work start until you’ve checked the basics

A practical homeowner checklist

Before the welder starts:

• confirm the exact scope of work in writing
• ask for a current certificate of insurance
• verify public liability cover and the policy expiry date
• check whether subcontractors are included
• confirm any council consent or other approvals needed
• make sure your own insurer is aware if the job is major or structural
• clear the work area and agree on protection for paths, walls, plants, and vehicles

The bottom line

Yes — in most cases, your welder should be insured, and public liability cover is the most important policy to ask about. For homeowners, insurance helps reduce the financial fallout if sparks, heat, tools, or equipment damage your property or injure someone.

The best approach is simple: get several written quotes, check that the welder has appropriate insurance for the type of work, and make sure any consent, licensing, or safety requirements are sorted before the job begins. A few minutes of checking can save a lot of stress later.
