Yes, a gutter cleaner in New Zealand can legally subcontract work to another person. Gutter cleaning is not a licensed or restricted trade in the same way that electrical or plumbing work is, so there is no specific law preventing subcontracting. However, there are important legal, contractual, and health and safety obligations that apply — and as a homeowner, it pays to understand what this means for you.
What Subcontracting Actually Means
Subcontracting is when a tradesperson or business you hire (the contractor) brings in a third party (the subcontractor) to carry out some or all of the work on your behalf. In the gutter cleaning industry, this is relatively common — particularly for larger companies that take on more bookings than their own staff can handle, or for sole traders who need a hand on bigger properties.
The key point is that the original contractor remains responsible to you, the homeowner, for the quality and completion of the work. The subcontractor works for the contractor, not directly for you — unless you have a separate agreement in place.
Is It Legal?
Gutter cleaning is not a restricted trade under New Zealand law. Unlike electrical work (regulated by the Electrical Workers Registration Board) or plumbing and drainlaying (regulated by the Plumbers, Gasfitters and Drainlayers Board), there is no licensing requirement for gutter cleaners. This means subcontracting is perfectly legal, provided:
- The original contract between you and the contractor does not specifically prohibit subcontracting.
- The subcontractor complies with all relevant health and safety obligations.
- The work is carried out to the agreed standard.
If your contract with the gutter cleaning company says the work will be done by their own staff and they send someone else without telling you, that could be a breach of contract — so it's worth checking the fine print.
Health and Safety Obligations
This is where things get serious. Working at height — which gutter cleaning almost always involves — carries real risk. Under the Health and Safety at Work Act 2015, both the primary contractor and the subcontractor have duties as persons conducting a business or undertaking (PCBUs). They must manage risks, particularly the risk of falls.
WorkSafe NZ sets out clear expectations for working at height, including the use of ladders, scaffolding, or other fall-prevention equipment. If a subcontractor is injured on your property, liability can be complex — which is why it's important that whoever turns up has their own:
- Public liability insurance
- Employer's liability or contractor's insurance (if they have workers)
- A clear understanding of safe working practices at height
As a homeowner, you also have a duty not to create or ignore hazards on your property that could put workers at risk.
What to Check Before Work Starts
Whether the job is done by the original contractor or a subcontractor, here's what you should confirm:
- Who will actually be doing the work? Ask upfront if the company uses subcontractors.
- Are they insured? Request proof of public liability insurance.
- Are they experienced? Subcontractors should have the same skills and equipment as the main contractor.
- Is there a written quote or contract? A written agreement protects both parties and sets out what's expected.
- Will the work meet any relevant standards? For example, if gutters are being repaired or replaced (not just cleaned), this may interact with the NZ Building Code requirements around roof drainage — particularly Clause E1 (Surface Water). Check with your local council if you're unsure whether a building consent is needed for any repair work.
Your Rights as a Homeowner
Under the Consumer Guarantees Act 1993 and the Fair Trading Act 1986, services must be carried out with reasonable care and skill, regardless of whether a subcontractor is used. If the work is substandard, your claim is against the contractor you hired — not the subcontractor directly.
If you have concerns about a business's trading practices, Consumer NZ is a useful resource for understanding your rights.
When to Call a Professional
While gutter cleaning itself doesn't require a licence, there are situations where you should make sure a properly qualified tradesperson is involved:
- Roof repairs or gutter replacement — this may require a Licensed Building Practitioner (LBP) depending on the scope of work.
- Any electrical work near gutters (e.g. heat tape, lighting) — must be done by a registered electrician under the EWRB.
- Downpipe connections to stormwater drains — may involve restricted drainlaying work regulated by the PGDB.
For straightforward gutter cleaning, hiring a reputable local professional is the safest and most practical option. You can find qualified gutter cleaners in your area on tradedirectory.co.nz.
