If you’re an electrician, electrical contractor, or a business that regularly engages electricians, you’ll know the job doesn’t start and end with the tools. It also starts with clear expectations.
An electrical service agreement is one of the simplest ways to set those expectations early, reduce misunderstandings, and protect your cashflow if something goes wrong.
This guide is updated for 2026 and reflects the way electrical work is commonly quoted, booked and delivered in New Zealand today (including remote approvals, variations by text/email, and ongoing maintenance arrangements).
Let’s walk through what an electrical service agreement is, how it works in practice, and what you should include so you’re protected from day one.
What Is An Electrical Service Agreement (And When Do You Need One)?
An electrical service agreement is a written contract between:
- the service provider (you, as the electrician/electrical company), and
- the customer (a homeowner, landlord, builder, business owner, property manager, or another contractor).
It sets out the “who, what, when, and how much” of the job, plus the rules for what happens if the job changes, is delayed, or ends up in a dispute.
Common Situations Where An Electrical Service Agreement Helps
Even if you’ve worked with someone before, a proper agreement is useful whenever:
- the job is high value (or could easily grow in scope)
- you’re dealing with a commercial customer or a head contractor
- the work involves multiple site visits (or coordination with other trades)
- you’re ordering parts and materials upfront
- there’s a tight timeframe, penalties, or critical deadlines
- you’re providing ongoing servicing or maintenance (rather than a one-off callout)
If you’re doing a quick, low-value residential fix, you might get away with a clear quote and good communication. But as soon as the job gets bigger or more complex, relying on verbal agreements can become a gamble.
Is A Quote The Same Thing As A Service Agreement?
Not really. A quote can be part of your agreement, but it usually doesn’t cover enough detail to protect you properly.
In New Zealand, a quote can still become legally binding in some circumstances (especially once it’s accepted and work starts), but that doesn’t automatically mean you have all the protections you’d want around variations, payment timing, delay responsibilities, or limitations of liability.
This is why many businesses use a full Service Agreement (or service terms) together with a statement of work or accepted quote.
How Does An Electrical Service Agreement Work In Practice?
Most electrical service agreements follow a simple lifecycle. If you understand that lifecycle, it becomes much easier to build a contract that actually matches how you do business day-to-day.
1) Scope Is Agreed (Before You Start Work)
The agreement should clearly define what you’re providing, for example:
- installation (lighting, switchboards, EV chargers, heat pumps, alarms, data/cabling)
- maintenance and servicing
- testing and tagging
- fault finding and repairs
- compliance work and documentation
It should also clarify what’s not included (this matters more than most people think). For example, you might exclude patching/painting, asbestos removal, builder’s work, or council consents being handled by you.
2) Price And Payment Terms Are Locked In (Or Clearly Variable)
You’ll normally price a job in one of these ways:
- Fixed price (often for a defined installation)
- Hourly / time and materials (common for fault finding or unknown issues)
- Milestone or progress payments (common for larger commercial work)
- Retainer / monthly fee (common for ongoing maintenance contracts)
Your agreement should match the pricing model. If it’s time and materials, your contract should say how hours are calculated, minimum callout charges, travel time rules, and how materials are charged (including supplier price changes).
3) Variations Are Managed (Because Something Always Changes)
Variations are one of the biggest causes of disputes in the trades.
A good electrical service agreement sets a simple rule like:
- the customer must approve variation costs before you do the additional work (ideally in writing), and
- you’re entitled to charge for extra work outside the agreed scope.
This is particularly important where the customer is on-site and says “while you’re here, can you also…”-that’s where jobs blow out and payments get delayed.
4) Completion, Sign-Off And Defects Are Dealt With Fairly
Most customers aren’t trying to be difficult-they just want to know what happens if something doesn’t work after you leave.
Your agreement should explain:
- what “completion” means (e.g. practical completion vs final completion)
- how sign-off happens (site sign-off, email confirmation, or a completion certificate)
- whether there’s a defects liability period (and what’s covered)
- what happens if the customer or another trade damages the work after completion
Getting this clear early reduces the risk of you being called back for issues outside your control.
What Should Be Included In An Electrical Service Agreement?
There’s no single “perfect” electrical service agreement, because the right contract depends on how you operate, who your customers are, and what types of jobs you take on.
That said, there are a few clauses we almost always recommend thinking through carefully.
Parties, Site Details And Who Can Give Instructions
This sounds basic, but it matters. You want clarity on:
- the legal name of the customer (especially if they’re a company or trust)
- the site address (and whether there are multiple sites)
- who is authorised to approve work and variations (important with property managers and construction sites)
If you accept instructions from “whoever is on site”, you may end up doing work the paying customer later says they didn’t authorise.
Scope Of Works (With Assumptions And Exclusions)
Your scope should be detailed enough to prevent confusion, but still practical.
Some examples of helpful scope wording include:
- brand/model assumptions for fittings and equipment
- whether disposal of old equipment is included
- access assumptions (e.g. clear ceiling space, no restricted access, normal business hours)
- what happens if existing wiring is non-compliant or unsafe
Timeframes, Delays And Access
Electrical jobs often rely on other people: builders, tenants, store managers, or suppliers.
Your agreement should say what happens if:
- the customer can’t provide access
- other trades aren’t ready
- materials are delayed
- the customer changes the schedule at short notice
It’s common to include rules around cancellation fees, standby time, or rescheduling charges (as long as they’re fair and clearly disclosed upfront).
Payment Terms, Late Payment And Debt Recovery
This is where contracts protect your cashflow.
Consider including:
- deposit requirements (especially where you’re ordering expensive materials)
- progress payments for staged work
- timeframes for payment (e.g. 7 days, 14 days)
- interest on late payments (if you intend to charge it)
- debt recovery costs (what you can claim if you have to chase payment)
If you’ve ever had to chase an unpaid invoice for weeks, you’ll know why it’s worth tightening this up early.
Health And Safety Obligations
In New Zealand, health and safety obligations aren’t optional. The Health and Safety at Work Act 2015 places duties on PCBUs (persons conducting a business or undertaking), which can include both you and your client depending on the situation.
Your agreement can help by clarifying responsibilities such as:
- site inductions and site rules
- hazard reporting
- who provides access equipment or safety systems (if needed)
- stop-work rights if conditions are unsafe
Contracts don’t replace health and safety compliance, but they do reduce confusion about who’s doing what on site.
Warranties, Consumer Rights And What You Can’t Contract Out Of
This is a big one, especially if you service residential customers.
Depending on who you’re contracting with and the purpose of the work, New Zealand consumer law may apply, including:
- Consumer Guarantees Act 1993 (CGA): services must be carried out with reasonable care and skill, fit for purpose, and completed within a reasonable time (among other guarantees).
- Fair Trading Act 1986: you must not mislead customers (including in advertising, quotes, or representations about compliance, timelines, or pricing).
If you provide services to a consumer, you generally can’t “contract out” of the CGA.
For business-to-business work, contracting out may be possible in some cases, but it needs to be done correctly and it won’t suit every arrangement. This is one of those areas where getting tailored legal advice is genuinely worth it, because a poorly drafted clause can create a false sense of security.
Liability, Indemnities And Insurance
Electrical work can carry real risk-property damage, business interruption, or safety incidents.
Your agreement should deal with:
- what you’re liable for (and what you’re not)
- indirect/consequential loss (e.g. lost profits due to downtime)
- caps on liability (where appropriate)
- the customer’s obligations (e.g. keeping the site safe, disclosing known issues)
- insurance requirements (public liability, professional indemnity if relevant)
It’s also common to define that you’re not responsible for pre-existing defects, hidden issues, or damage caused by third parties after completion-so long as it’s fair and clearly drafted.
Termination And Dispute Resolution
If a relationship breaks down mid-job, you want a clean process for ending it without things escalating.
Most electrical service agreements include:
- termination for breach (e.g. non-payment)
- termination for convenience (sometimes, with notice)
- what happens to deposits and ordered materials
- how disputes will be handled (negotiation first, then mediation, then court/tribunal if needed)
If you need a more formal “end point” document (for example, to settle a dispute with agreed payment terms), a Deed of Settlement can be a practical option.
What Legal Risks Does An Electrical Service Agreement Help You Avoid?
Contracts don’t eliminate risk completely, but they make risk manageable. Here are some of the most common issues we see in service-based trades, and how a written agreement helps.
Scope Creep And Unpaid Variations
Without clear scope and variation rules, you might do extra work “to be helpful” and then struggle to invoice for it later.
A good agreement makes it normal and expected that extra work is treated as a variation and billed accordingly.
Non-Payment Or Slow Payment
If payment terms are vague, customers will pay when it suits them.
A written agreement sets:
- when payment is due,
- what happens if payment is late, and
- your rights if you need to pause work due to non-payment.
Disputes About Quality Or “Defects”
Sometimes the issue is genuinely a defect. Sometimes it’s a misunderstanding about what was included (or a problem caused by someone else after the fact).
Clear completion and defects clauses reduce the “he said, she said” factor.
Misunderstandings About Compliance And Responsibilities
Electrical work has compliance expectations, and customers often assume you’ll take care of everything.
Your agreement can clarify things like:
- who is responsible for consents (if any)
- who provides access and shutdown windows
- what documentation will be provided at the end of the job
Damage To Property Or Third-Party Loss
When something goes wrong, customers often look for someone to blame quickly-especially where there’s business downtime or an insurance claim.
A properly drafted liability clause (paired with appropriate insurance) helps protect your business and set reasonable boundaries around what you’re responsible for.
Special Scenarios: Subcontracting, Ongoing Maintenance, And Handling Customer Data
Some electrical businesses run on straightforward one-off jobs. Others operate with subcontractors, recurring service arrangements, or technology systems that collect customer information.
These scenarios often need an extra layer of legal clarity.
If You Use Subcontractors
If you engage subcontractors (rather than employees), it’s important to have the right paperwork in place so everyone is clear on standards, payment, and responsibility for defects or rework.
A tailored contractor vs subcontractor approach also helps reduce the risk of misclassification and disputes about entitlements.
Where you’re using subcontractors regularly, consider using a dedicated Contractor Agreement so your service agreement with the customer lines up with your arrangements behind the scenes.
If You Provide Ongoing Maintenance Services
Ongoing maintenance is a great way to build recurring revenue, but it also creates ongoing obligations that should be properly defined.
Your agreement should cover things like:
- service frequency (monthly, quarterly, annually)
- response times (and what counts as an “emergency” callout)
- what’s included in the maintenance fee vs billed separately
- how price increases are handled
- minimum term and renewal rules
This is where a broader services contract structure (sometimes combined with a schedule of works) can be helpful, rather than relying on individual quotes each time.
Many electrical businesses now use job management systems, store customer contact details, and take photos of switchboards or site conditions for records.
If you collect personal information, you should think about your obligations under the Privacy Act 2020, including how you store information securely and what you tell customers about how their information will be used.
Depending on how you operate (especially if you take bookings online), having a clear Privacy Policy is a practical way to set expectations and show you take privacy seriously.
Key Takeaways
- An electrical service agreement is a written contract that sets clear rules for scope, pricing, timing, variations, and what happens if there’s a dispute.
- Even if you use quotes, a service agreement adds key protections around variations, late payment, liability boundaries, and completion/sign-off.
- Your agreement should be tailored to your pricing model (fixed price vs time and materials vs progress payments) so payment terms match how you actually bill.
- New Zealand consumer and fair trading laws can apply to electrical services, and you generally can’t contract out of consumer guarantees for residential customers.
- Clear clauses on access, delays, health and safety responsibilities, and defects handling reduce misunderstandings and help protect your reputation.
- If you use subcontractors, do ongoing maintenance, or collect customer data, you’ll often need extra contract terms to cover those risks properly.
