Terms Of Trade For Electrical Contractors

Yes, if you run an electrical contracting business in New Zealand, you should have clear written terms of trade before you start work. Good terms help you get paid on time, manage call-out fees and variations, and set realistic limits around warranties, parts and liability.

The more nuanced part is that electrical work can look very different from job to job. A 30-minute diagnostic call-out, a switchboard upgrade, an urgent after-hours fault and a commercial fit-out all carry different payment and risk issues.

Your terms of trade and business terms need to reflect how your business actually works. For electrical contractors, that usually means dealing properly with call-outs, diagnostics, materials, compliance certificates, delays, variations, payment terms and late payment risk.

What Should Electrical Contractor Terms And Conditions Cover?

Your electrical contractor terms and conditions, including any terms of sale, should cover the full journey from quoting to final payment. That means they shouldn't just say what the job is and what it costs. They should also explain what happens when the job changes, parts cost more, access is delayed or the customer doesn't pay.

For an electrical contractor, strong terms usually cover:

• Scope of work: what services you're agreeing to provide, and what is excluded.
• Quotes and estimates: whether pricing is fixed, hourly, provisional or subject to inspection.
• Call-out fees: minimum charges, travel time, after-hours rates and cancellation fees.
• Diagnostics: whether fault-finding is charged even if the customer decides not to proceed with repairs.
• Materials and parts: when parts must be paid for, who owns them before payment, and what happens if prices rise.
• Variations: how changes to the work are approved and charged.
• Compliance documents: when you'll issue certificates or records required for electrical safety.
• Payment terms: deposits, progress payments, due dates, late payment interest and suspension rights.
• Customer responsibilities: site access, accurate information, safe working conditions and other trades being ready.
• Liability limits: reasonable limits on indirect losses, existing faults and issues outside your control.

Templates can be a useful starting point, but they often miss the practical details that matter for tradies. Your terms will work much better if they're tailored to your quoting process, job size, customer type and payment model.

Do I Need Different Terms For Residential And Commercial Electrical Jobs?

Yes, it's often worth having different terms, or at least different clauses, for residential and commercial jobs. The main reason is that consumer protection laws apply differently depending on who your customer is and why they're buying your services.

For residential customers, the Consumer Guarantees Act 1993 will often apply. This means your electrical services need to be carried out with reasonable care and skill, be fit for the agreed purpose, and be completed within a reasonable time if no timeframe is agreed. You generally can't contract out of those guarantees when you're dealing with a consumer.

The Fair Trading Act 1986 also matters. Your quotes, advertising and conversations with customers must not be misleading. If you say a job will be completed by Friday, that a product is a particular brand, or that a price is all-inclusive, you need to be comfortable standing behind that statement.

For business customers, you may have more flexibility. In some business-to-business contracts, you may be able to contract out of parts of the Consumer Guarantees Act and some Fair Trading Act provisions, if the law allows it and it's fair and reasonable to do so. This needs to be drafted carefully.

Residential Jobs

For residential work, your terms should be plain and easy to follow. Many payment issues come from customers not understanding that a call-out fee applies, or that fault-finding is chargeable even if the repair itself doesn't go ahead.

Your residential terms should make clear whether prices include GST, when deposits are payable, how hourly rates are calculated, what after-hours or emergency rates apply, when a customer can cancel or reschedule, how variations are approved and what warranties apply to workmanship and supplied products.

Commercial Jobs

For commercial work, your terms of trade may need more structure. Larger jobs often involve progress claims, staged works, main contractor requirements, project delays and coordination with other trades.

Your commercial terms should deal with purchase orders and authority to approve work, progress payments, retentions, site inductions, access requirements, delays caused by builders or suppliers, variation processes and limitations on consequential loss, business interruption and loss of profits.

How Should I Set Payment Terms For Electrical Work?

Your payment terms should tell customers exactly when and how they need to pay you. For electrical contractors, this is one of the most important parts of your terms because labour, fuel and materials costs often land before you receive final payment.

Common tradie payment terms in New Zealand include:

• Payment on completion: often suitable for smaller residential jobs and call-outs.
• Deposit upfront: useful where you need to order parts, book labour or reserve a job date.
• Progress payments: common for larger residential projects and commercial work.
• Payment within a set period: for example, payment due 7 days after invoice or 20th of the month following invoice, depending on your business model.
• Card or online payment terms: if you accept card payments, you should say whether surcharges apply and when payment is treated as received.

If your work falls within the Construction Contracts Act 2002, you may also be able to use formal payment claims. That Act applies to many construction work arrangements in New Zealand, including work involving electrical systems in buildings. Payment claims have specific requirements, so it's worth getting the format right if you intend to use them.

A practical payment clause might say that invoices are due within 7 days, that deposits must be paid before materials are ordered, and that you can pause further work if an overdue invoice remains unpaid after notice. Without clear payment terms, you may struggle to recover unpaid invoices or justify pausing work when a customer falls behind.

Can I Charge Call-Out Fees And Diagnostic Fees?

Yes, you can charge call-out and diagnostic fees, as long as you're clear about them before the customer books the job. This is especially important for electrical work because finding the fault can be the most valuable part of the service.

Your terms should explain what the call-out fee covers. For example, it might include travel to the site, the first 30 minutes of labour, basic testing and advice on next steps. Or it might only cover attendance, with all labour charged separately.

Diagnostic fees should also be clear. If you attend a property, test circuits and identify that the issue is a damaged appliance rather than wiring, you've still provided a service. Your terms should say that diagnostic or fault-finding time is chargeable whether or not the customer approves repair work.

Say WireWorks Electrical attends a rental property after hours because power is out in part of the house. The electrician spends 45 minutes testing the switchboard and circuits, then finds the issue is a faulty appliance supplied by the occupant. If WireWorks' terms clearly say after-hours call-outs and diagnostics are payable even when no repair is carried out, it's much easier to invoice confidently.

Your call-out terms can also deal with minimum charges for short jobs, travel time for out-of-area work, parking or site access costs, cancellation fees, no-access fees and different rates for evenings, weekends and public holidays.

For residential customers, make sure these charges aren't hidden in fine print. The clearer you're before the booking is confirmed, the less likely the customer will push back later.

How Do Variations Work In An Electrical Services Contract?

Variations should be approved before you do the extra work wherever possible. Electrical jobs can change quickly, so your terms need a simple process for agreeing changes without slowing the job down.

A variation is any change to the agreed scope, price, timing or materials. For example, the customer asks for additional power points, you discover unsafe or non-compliant wiring, the switchboard requires additional parts not visible during the quote, the builder changes the layout after rough-in, a specified fitting is unavailable or access issues mean the job takes longer than expected.

Your terms should say how variations can be approved. For smaller jobs, approval by text message or email may be practical. For larger jobs, you might require a signed variation form or updated quote.

The key is to avoid doing extra unpaid work because you were trying to keep the job moving. If the terms say that variations are charged at your standard hourly rates plus materials, and that written approval can be given by email or text, you have a much clearer basis for invoicing.

What If The Extra Work Is Needed For Safety?

If extra work is needed because of an immediate electrical safety issue, your terms should allow you to take reasonable steps to make the site safe. You should still tell the customer as soon as practical and explain the likely cost before continuing with non-urgent extra work.

Electrical safety obligations can sit alongside your contract terms. Depending on the work, the Electricity (Safety) Regulations 2010 and related WorkSafe guidance may be relevant. Your terms shouldn't promise to cut corners or leave unsafe work in place just because the original quote was narrower.

Can I Include A Materials Price Rise Clause?

Yes, a materials price rise clause can be included, and it's often very useful for electrical contractors. Parts, cable, switchboards and fittings can change in price between quoting and installation, especially where jobs are booked weeks or months ahead.

A good materials price rise clause explains when you can adjust the price and how you'll tell the customer. It should be fair and specific, not a blank cheque to increase prices whenever you like.

For example, your terms might say that quoted prices for materials are based on supplier prices available at the date of the quote, and that you can pass on supplier price increases if materials aren't purchased within a certain time or if the customer delays acceptance of the quote.

Your clause could also deal with substitutions. If a specified product is unavailable, your terms can allow you to recommend a comparable alternative, subject to customer approval where the difference affects price, appearance or performance.

For residential customers, price rise clauses need to be especially clear and fair. If a customer sees a fixed price quote, they may assume that price is locked in. If it's not, the quote and terms should say so upfront.

For commercial work, you may want a more detailed clause covering supplier price increases, foreign exchange changes for imported products, freight delays, special order costs, product discontinuation, storage costs if the customer delays installation and expiry dates for quotes.

What Should My Terms Say About Compliance Certificates And Safety Documents?

Your terms should say which compliance documents you'll provide and when you'll provide them. For electrical work, paperwork can be just as important as the physical installation, especially for customers who need records for insurance, property management or project completion.

Depending on the work, you may need to provide documents such as a Certificate of Compliance, an Electrical Safety Certificate or a Record of Inspection. The exact requirement depends on the type of prescribed electrical work and the applicable electrical safety rules.

Your terms should make it clear that any legally required electrical safety documents will be issued and provided within the statutory timeframes, regardless of whether an invoice has been paid. For example, the Electricity (Safety) Regulations 2010 set rules around when certain certificates and safety documents must be issued or provided, and failing to comply can have offence consequences. Your payment policy shouldn't try to delay or override those obligations.

That said, your terms can still distinguish between required documents and optional admin services. For example, you might include required certificates in the quoted price, while charging a reasonable admin fee for extra copies, replacement documents or optional reporting that isn't legally required.

It can help to say:

• which documents are included in the quoted price;
• whether extra copies or replacement documents attract an admin fee;
• what information the customer must provide for the documents;
• whether third-party inspection costs are included or excluded;
• when documents will be issued; and
• what happens if the customer changes the work after certification.

Your terms should also explain that certificates relate to the work you've performed, not to unrelated pre-existing defects. This helps avoid a customer assuming you've certified an entire property when you only completed a specific piece of work.

How Can I Limit Liability Without Being Unfair?

You can usually limit some liability in your terms, but you can't use your terms to avoid responsibilities the law doesn't let you avoid. The safest approach is to be clear, fair and specific about what you're and aren't taking responsibility for.

For electrical contractors, liability clauses often deal with pre-existing faults or non-compliant wiring you didn't install, hidden conditions, customer-supplied products, delays caused by other trades, site access problems, late customer decisions, loss of data, business interruption or lost profits for commercial customers and manufacturer warranties for products and parts.

For consumer customers, the Consumer Guarantees Act still applies. You shouldn't say things like all warranties are excluded or no responsibility is accepted for workmanship. Clauses like that can create Fair Trading Act risk if they mislead customers about their legal rights.

For business customers, you may be able to set a liability cap, such as limiting liability to the amount paid for the relevant services or the cost of re-performing the work. Whether that's appropriate depends on the job, the customer and the risk profile.

Your terms should also work alongside your insurance. If your public liability or professional cover has exclusions, excesses or notification requirements, your contract shouldn't promise more than your business can realistically carry.

What Other Clauses Should Electrical Contractors Include?

Your terms should include a few practical clauses that make day-to-day jobs easier to manage. These clauses aren't always front of mind when you're busy on the tools, but they can save a lot of stress later.

Quote validity: say how long a quote remains open, so materials, labour and availability don't stay locked in indefinitely.

Access and site readiness: require the customer to provide safe access, parking where needed, clear work areas and accurate information about the site. If other trades need to finish first, your timing should depend on the site being ready.

Ownership of materials: you can include a retention of title clause stating that materials remain yours until paid for, to the extent the law allows. This can be useful where you've supplied expensive parts before final payment.

Subcontractors: if you use subcontractors, your terms should allow this while making clear that work must still meet the required standard.

Privacy and health and safety: if you collect customer names, addresses, site photos or payment details, the Privacy Act 2020 may apply. Your terms can also allow you to refuse or pause work if a site is unsafe.
