When a gutter cleaner turns up at your home, it's reasonable to want to know they're working safely and within the law. In New Zealand, working at height is one of the leading causes of serious workplace injuries, so there are clear rules tradespeople must follow — and as a homeowner, you have every right to ask questions before work begins.
Why Height Safety Matters for Gutter Cleaning
Gutter cleaning almost always involves working at height — whether that's a single-storey home with eaves around 3 metres off the ground, or a two-storey house where a fall could be fatal. WorkSafe NZ sets out the legal obligations for anyone doing work at height in New Zealand under the Health and Safety at Work Act 2015 (HSWA). These rules apply to self-employed tradespeople and businesses alike.
As a person conducting a business or undertaking (PCBU), a gutter cleaning company must manage the risks of working at height. As a homeowner engaging them, you are also considered a PCBU in some circumstances — meaning you share a duty to ensure the work environment is reasonably safe.
What the Law Requires
Under the HSWA and associated regulations, anyone working at height must:
- Identify and assess the risk of a fall before starting work
- Eliminate the risk where practicable (e.g. using long-reach tools from the ground)
- If elimination isn't possible, minimise the risk using controls like ladders, scaffolding, or fall-arrest systems
- Ensure equipment is fit for purpose, regularly inspected, and used correctly
There is no specific height threshold that automatically triggers scaffolding requirements for residential gutter cleaning — it depends on a risk assessment. However, WorkSafe NZ guidance makes clear that falls from even 2–3 metres can cause serious injury or death, so controls must always be in place.
What to Look for When a Gutter Cleaner Arrives
Here are practical things you can observe or ask about:
Ladders
- Is the ladder in good condition — no cracked rungs, bent rails, or missing feet?
- Is it the right type and length for the job? An A-frame ladder is generally used for lower work; an extension ladder for higher eaves.
- Is it set at the correct angle (roughly 1 metre out for every 4 metres up)?
- Is someone footing the ladder (holding it steady at the base), or is it secured another way?
- Are they maintaining three points of contact when climbing?
Scaffolding or Elevated Work Platforms
- For taller or more complex homes, a reputable operator may use a mobile scaffold tower or hire an elevated work platform (EWP/cherry picker).
- Scaffolding should look stable, properly braced, and have guardrails.
Personal Protective Equipment (PPE)
- Non-slip footwear is a basic requirement.
- For higher-risk work, a fall-arrest harness anchored to a suitable point may be appropriate.
Ground-Level Tools
- Many modern gutter cleaners use vacuum systems, water-fed poles, or blower attachments that allow them to clean gutters from the ground entirely — the safest option of all.
Questions to Ask Before Hiring
Don't be shy about asking a gutter cleaner the following before they start:
| Question | Why It Matters |
|---|---|
| Do you have public liability insurance? | Covers damage to your property |
| Do you have a health and safety plan for working at height? | Shows they've thought about risk |
| Are you self-employed or do you have employees? | Affects their PCBU obligations |
| What equipment will you use? | Lets you assess their approach |
| Can I see your ladder or equipment? | A confident professional won't mind |
Red Flags to Watch Out For
- Arriving with a wobbly, damaged, or too-short ladder
- Working alone at height with no ladder footing or securing method
- Refusing to answer questions about their safety approach
- No evidence of public liability insurance
- Rushing the job without any apparent risk assessment
If you see unsafe practices, you are within your rights to ask them to stop work. You could also report serious concerns to WorkSafe NZ.
Is Gutter Cleaning Licensed or Restricted Work?
Gutter cleaning itself is not restricted or licensed work under New Zealand law — unlike electrical or plumbing work, which must be carried out by licensed professionals registered with the Electrical Workers Registration Board or the Plumbers Gasfitters & Drainlayers Board. However, the health and safety obligations around working at height are legally binding on anyone doing the work commercially.
If your gutters are connected to a downpipe issue that involves drainage work, that may cross into restricted drainlaying territory — check with the PGDB if you're unsure.
When to Call a Professional
Always hire a professional gutter cleaner for:
- Two-storey or higher homes where ladder work carries significant fall risk
- Steep or complex rooflines that make access difficult
- Older homes where gutters or fascias may be fragile
- Any situation where you're not confident the person doing the work has the right equipment and knowledge
