Most marketing advice for plumbers is written for American plumbing companies with a fleet of vans and a social media manager. Post three times a week, film a TikTok, buy a billboard. For a New Zealand plumber, most of the work comes from something much simpler: being the name someone finds, and gets hold of, at the moment the hot water dies or the drain backs up.
That makes plumbing marketing mostly a search problem. Which searches turn into paying jobs, which ones quietly burn your budget, and what has to be in place so the right searches find you.
This guide is built on our own data rather than a keyword tool’s guesses. We pooled the search terms that triggered ads across the plumbing and gas accounts we manage over 12 months (to 23/08/2026), kept the ones with real hiring intent, and priced them against Google’s Keyword Planner for New Zealand. Search volumes below are Keyword Planner’s 12-month NZ averages from that pull. Our bias, up front: we run Google Ads for trade businesses for a living. The data is the data either way.
Two kinds of plumbing work, two kinds of search
Plumbing demand splits in two, and your marketing has to handle both.
Urgent work. No hot water, a blocked toilet, a burst pipe, a leaking cylinder. The customer is stressed, searching on a phone and ringing the first plumber who looks competent and picks up. They don’t compare five websites. Speed and visibility win.
Planned work. A cylinder replacement, a new shower, a gas hob install, a commercial maintenance contract. The customer has time, gets a couple of quotes and reads reviews. Proof and follow-up win.
The same plumber needs both, but they’re found by different searches, convert in different ways and deserve different budgets.
The searches that bring in work
Ranked roughly by what produced real enquiries in our accounts:
| Search type | Examples | NZ searches a month | Why it works |
|---|---|---|---|
| Plumber + town | plumbers hamilton, plumber in tauranga | 2,900 for the Auckland family; 13,580 across 16 centres | The single strongest converter in our data. Someone ready to hire, in your area. |
| Near me | plumbers near me, plumber near me | 6,600 | Phone searches with the location built in. High intent, high competition. |
| Gas fitter + town | gas fitter christchurch, gas fitter near me | 1,820 across 16 centres | Converts far better than its volume suggests (see below). |
| Fault and symptom | no hot water, hot water cylinder leaking, blocked drain | 140 to 390 per family | The customer has the problem right now. The best buyers in the account. |
| Specific job | hot water cylinder replacement, shower installation, toilet replacement | 590, 260, 90 | Planned work, lower cost per click, worth its own ad group and page. |
| Emergency | emergency plumber + town, 24 hour plumber | 630 across 16 centres | Highest intent and highest cost per click. Budget it properly or leave it out. |
Three findings worth carrying into any plumbing account.
Gasfitting is the most underrated line on the list. “Gas fitter + town” produced 8.5 tracked enquiries from 53 clicks across four of our accounts, second only to the generic plumber terms, and it’s far less contested. Most plumbers who are also gasfitters don’t advertise it separately. If you hold a gasfitting licence, give it its own ad group and its own page.
Emergency terms are a budget decision, not a keyword decision. “Emergency plumber + town” showed our ads thousands of times and won very few clicks at the bids we were running. That’s competition, not a lack of demand. Either fund an emergency group properly, with your after-hours phone actually covered, or leave it out and put the money where you can win. Paying for after-hours clicks and letting them ring out is the worst of both. (If you don’t do call-outs, here’s how to handle after-hours calls instead.)
Size matters more than structure. On the core plumber terms, Auckland has roughly three times the searches of Christchurch and seven times a provincial centre. Outside the main three cities, the specialist long tail (leak detection, drainlaying, blocked drains) is close to zero. Building fifteen tight ad groups for a provincial town starves all of them. Two or three groups plus a wide negative list works better. One exception: septic tank cleaning has more relative volume in the provinces than in Auckland, so it’s worth a group for anyone servicing rural properties.
Plumbing is also seasonal. Hot water and drainage searches climb in winter, so a term averaging 40 searches a month can do 100 in July. Plan budget for it.
The searches that waste money
Every plumbing account we’ve taken over had money leaking into the same places. These are the negatives to add on day one.
- Job seekers: jobs, “plumber job”, apprenticeship, apprentice, salary, wages, course, training, vacancies. “Plumber job” and “plumbing apprenticeship” look like plumbing searches and will never book a call-out. Block “job” as a phrase rather than on its own, because “small plumbing job” is a customer.
- DIY and research: how to, diy, youtube, tutorial, video.
- Merchants and retail: mico, plumbing world, bunnings, mitre 10, placemakers, trade depot, plumbing plus. People searching for the merchant want the merchant.
- Appliance brands: rheem, rinnai, bosch, thermann, stiebel, zip, methven, caroma, grundfos, davey, onga and similar. These searchers are usually shopping for a product, not a plumber.
- Product and spec shopping: litre, litres, 180l and other sizes, mm, bsp, kpa, fittings, coupling, elbow, cartridge, spec, datasheet, dimensions, for sale, wholesale, second hand.
- Out-of-area places: every town and region outside your service area, especially if you run broad match or AI Max, which both stretch location intent.
- Renovation and new build, only if you prefer repair and maintenance work: renovation, remodel, fit out, extension, architect, new bathroom.
Don’t let a generic negative list block your best customers
This one catches out a lot of accounts, including ones run by agencies. Many “universal” negative keyword lists floating around were written for general lead generation, and they block words like not working, broken, problem, help and even certified.
For a plumber, those are buyer words. “Hot water cylinder not working” is a call-out. “Toilet broken” is a call-out. “Certified gas fitter near me” is someone who checks licences before they hire. Never negative the fault and symptom cluster: no hot water, not working, broken, leaking, blocked, overflowing, burst. And don’t block install, installation or replacement: a failed cylinder replacement is repair work.
If you’re using a shared negative list, read every line of it against your services before you attach it.
How to structure a plumbing campaign
The ad group split that has worked across our plumbing accounts, roughly in order of lead quality:
- Emergency and after hours, with its own budget and a 24/7 message (only if you actually answer).
- Blocked drains, with its own landing page.
- Hot water, repair and replacement together (they convert alike).
- Leaks and burst pipes, kept apart from emergency so the copy stays specific.
- Gasfitting, a different licence and a different searcher.
- Bathroom and kitchen fixtures, lower urgency and lower cost per click.
- General plumber + town, the broad catch-all.
- Commercial, if you do it: low volume, high value, different copy.
In a provincial town, collapse that to two or three groups. Run the town and near-me terms as phrase match, keep exact match for the proven converters, and only open up broad match once the negative list is tight and the campaign is bidding on real conversions.
Two details that trip people up. Google won’t approve ads with a phone number typed into the headline or description: put your number in a call asset instead. And Google’s own call-forwarding numbers aren’t available in New Zealand, so calls made straight from your ad show up as clicks, not tracked calls. A third-party call tracking service fixes that; we set it up for clients who want it. (More on what to ask an agency about call tracking. If the clicks are coming but the phone isn’t ringing, work through these eight checks.)
On cost: Keyword Planner’s top-of-page bids for “plumbers + town” run from about $5.70 to $17.30 a click, and other plumbing terms sit in a similar band. Our full table by trade is in what Google Ads costs in NZ.
What has to be in place before the ads
Ads amplify whatever they point at. Four things decide whether a click becomes a job.
Your Google Business Profile. For “plumber near me” searches, the map pack usually sits above or alongside the ads. A complete profile, the right service area, real photos and steady reviews decide whether you’re in it. How the map pack really works.
Proof of licence. Homeowners can check every plumber, gasfitter and drainlayer on the Plumbers, Gasfitters and Drainlayers Board register. Put your registration and licence classes on your website and profile so they don’t have to go looking, and say so if you’re a Master Plumbers member.
A page for each service. Someone searching “blocked drain” should land on a page about blocked drains, with your number at the top, a tap-to-call button, a short form and reviews from people who had the same problem. Sending every click to your home page wastes the intent you paid for.
Someone, or something, picks up. Urgent customers ring the next plumber if you don’t answer. If you’re on the tools all day, here’s who answers the phone when you can’t.
For planned work, add one more: follow-up. Cylinder replacements and bathroom jobs get quoted against two or three others, and the plumber who chases the quote politely wins more of them. Do you actually follow up your leads?
A 90-day plan for a plumber starting from scratch
Week one. Claim and complete your Google Business Profile. Add your PGDB registration to the website. Start asking every customer for a review.
Weeks two to four. Make sure each main service has its own page. Launch Google Ads with the plumber + town, near-me, gasfitting and hot water groups, phrase match, the full negative list above and conversion tracking on calls and forms.
Months two and three. Read the search terms report every week and add negatives. Move budget toward the groups producing real jobs. Decide whether you can actually cover an emergency group, and add it only if you can.
From there, the ads tell you which searches turn into work, and SEO and reviews make those same searches cheaper over time. (Google Ads or SEO first?)
Marketing for plumbers: FAQ
How do I advertise as a plumber?
Start where urgent customers look: Google. Complete your Google Business Profile, get a website with one page per service, then run Google Ads on plumber + town, near-me and your best service terms with a strong negative list from day one. Facebook and Instagram suit planned work like bathroom fixtures, but nobody with a burst pipe is scrolling.
What are effective marketing ideas for plumbers?
The ones that compound: reviews after every job, a separate ad group and page for gasfitting if you’re licensed, showing your PGDB registration, answering or capturing every call, and following up every quote for planned work. They’re less exciting than a viral video and they win far more jobs.
How much should a plumbing company spend on marketing?
You’ll see “8 to 15% of revenue” quoted online, usually without a source. Work backwards instead: decide how many extra jobs a month you want, how many enquiries it takes to win one, and what an enquiry is worth given your margin. That gives you an ad budget tied to results. For reference, our managed Google Ads are a monthly package that covers our management and your ad budget in one price, sized to your area and how much work you want, with a one-off $497 +GST setup.
Is $10 a day enough for Google Ads?
For a plumber in a provincial town with one tight ad group, it can get you started. In a main centre, where top-of-page bids for plumber + town reach $15 or more, $10 a day buys a handful of clicks at best and you’ll rarely show at the busy times. Start with your best-converting group and enough budget to show all day, rather than spreading $10 across everything.
Do Google Local Services Ads work for plumbers in NZ?
Not yet. Local Services Ads (the “Google Guaranteed” style listings you’ll read about in American guides) aren’t available in New Zealand. In NZ, the paid options are standard Google Ads, alongside the free map pack.
