Google Ads for Plumbers

How much should a plumber spend on Google Ads?

Set your budget by working back from the most you can afford to pay for a booked job, not from a round number. As a rule of thumb, budget for at least 50 clicks a month on each job type you test. At current Australian click costs, that’s about $1,000 a month for hot water replacement and $2,500 or more for emergency searches.

Click costs vary a lot between plumbing searches. These are Google’s Keyword Planner estimates for Australia, pulled in October 2026:

Search term	Monthly AU searches	Est. cost per click	Top-of-page bid range
plumber near me	49,500	$38	$9–$45
emergency plumber	3,600	$49	$5–$46
emergency plumber near me	2,900	$55	$10–$51
blocked drain plumber	1,600	$61	$9–$49
gas plumber	1,300	$45	$10–$43
hot water repairs	480	$44	$8–$34
24 hour plumber	390	$31	$4–$40
hot water system replacement	2,900	$21	$4–$25
drain relining	140	$26	$7–$48

The pattern is clear. Urgent searches cost the most per click, because every plumbing advertiser wants them. Hot water replacement costs less than half as much per click, and the job is usually worth more. That’s why a plumbing budget should be split by job type, not spread across one “plumber” campaign.

Search volume also caps what you can spend usefully. In a single regional city, there may only be a handful of “blocked drain plumber” searches a day. Doubling the budget won’t double the calls if the searches aren’t there.

What does a plumbing lead actually cost?

A plumbing lead costs your average cost per click divided by the share of clicks that call or enquire. Divide that again by the share of leads you book, and you get your cost per job, which is the number that matters. A $55 click with a 10% enquiry rate is a $550 lead before you’ve quoted anything.

Here’s the maths for three hypothetical campaigns. Click costs are Google’s Australian estimates; the enquiry and booking rates are illustrative assumptions to show the method, not benchmarks:

	Emergency drains	Hot water replacement	General “plumber near me”
Cost per click	$55	$21	$38
Enquiry rate (calls and forms)	15%	10%	12%
Cost per lead	$367	$210	$317
Share of leads booked	60%	50%	50%
Cost per booked job	$611	$420	$633
Indicative job value	$150–$400 clear; $350–$900 with CCTV	$800–$3,000 storage; $3,450–$6,900 heat pump	Mixed

On those numbers, a basic drain clear loses money on the first visit. The emergency drain campaign only works if a good share of those calls lead to CCTV inspections, relining quotes or repeat customers. Hot water replacement, by contrast, can pay on the first job.

Take a hypothetical plumber in Newcastle spending $3,000 a month on hot water searches. At $21 a click that’s about 140 clicks, 14 enquiries and 7 booked replacements, at about $430 each. If each replacement earns $600 or more in margin, the campaign pays for itself and leaves profit, before counting the repeat work those customers bring.

Run your own numbers before you spend. If you don’t know your booking rate or average job value, track them for a month first. Guessing is how plumbers end up paying $60 a click for $200 jobs.

How should a plumbing Google Ads campaign be set up?

Set up separate campaigns for emergency and planned work, with an ad group for each job type and a landing page that matches it. Then add an ad schedule, location settings that target people actually in your area, call assets, and negative keywords that block job seekers and DIY searches.

The settings that matter most for plumbers:

• Emergency and planned campaigns. Emergency searches need a high budget share in the hours you answer. Hot water, gas and relining campaigns can run steadily and send people to detailed pages.
• Location targeting. Use the “presence” option, which targets people in or regularly in your area, rather than people merely interested in it. Otherwise someone in another state reading about your suburb can trigger your ad.
• Call assets. Show your number on the ad so mobile searchers can call without visiting the site. Most emergency plumbing leads are phone calls.
• Conversion tracking. Count calls from ads, calls from the landing page and form submissions. Use a minimum call length so wrong numbers and hang-ups don’t count as leads.
• Landing pages. A hot water ad should land on a hot water page, not your home page. See website design for plumbers for what those pages need.

Negative keywords stop you paying for searches that will never book a job. Start with these and add more from your search terms report each week:

Block searches containing	Why
jobs, salary, apprentice, apprenticeship, TAFE, course	Job seekers and students, not customers
how to, DIY, video, YouTube	People trying to fix it themselves
Bunnings, parts, spare, element, thermostat	Parts shoppers, unless you sell parts
free, cheap, cheapest	Price shoppers, if your margins can’t take them
Suburbs and regions you don’t service	Calls you’ll have to turn away

How do you run after-hours plumbing ads without wasting money?

Run after-hours ads only for the hours someone reliably answers, and bid up in the evening and weekend windows that book jobs. A missed call at 10pm costs you the $50 click and sends the customer to the next plumber. The ad schedule should match your roster, not the other way round.

A sensible approach is a separate emergency campaign with its own schedule and budget. During business hours it competes with every plumber in town. After hours, fewer plumbers are bidding, but the customers are the most urgent. Watch the report for a month, then shift budget towards the hours that produce booked jobs.

Two practical points. First, if your after-hours rates are higher, say so on the landing page, so the customer isn’t surprised and you don’t get a bad review. Second, if calls divert to a mobile at night, test the number from an ad yourself. A broken diversion can burn a week of budget before anyone notices.

Seasonality affects budgets too. In Google’s Australian data, “hot water system” searches sit between 12,100 and 14,800 a month over summer and climb to about 18,100 from April through the cooler months. Raise hot water budgets before winter, not after.

Do licence and advertising rules apply to plumbers’ Google Ads?

Yes. Several states require a plumber’s licence number in advertising, and Australian Consumer Law applies to every ad. Regulators haven’t published Google Ads-specific rules that we’ve found, so the safe approach is your licence number on every landing page and in your Business Profile, and in ad text where it fits.

The main rules plumbers advertise under:

• WA. Regulation 25 of the Plumbers Licensing and Plumbing Standards Regulations 2000 requires a licensed plumbing contractor or permit holder to show the licence or permit number in any advertisement for the business, with a fine of up to $2,000.
• NSW. NSW Fair Trading requires the licensee’s name and licence number in all advertising, including internet advertising.
• QLD. Section 54 of the QBCC Act requires licensees’ advertisements to state the licensed name, that they’re licensed under the QBCC Act, and the licence number. QBCC lists websites and online directories as advertising.

Watch price claims in ad text too. NSW Fair Trading’s guidance for trade advertisements says you can’t state a price that’s only part of the cost unless the single price is also clearly stated. If you advertise a “$99 call-out”, make it clear on the landing page what that covers and what costs extra.

One channel note: when we checked Google’s Local Services Ads help centre in October 2026, Australia wasn’t on its list of supported countries for those pay-per-lead listings. For now, Search ads are the main paid option on Google for Australian plumbers.

What does Google Ads management cost for plumbers?

Typical Australian market ranges for Google Ads management are $500–$1,500 per month, with ad spend paid separately to Google. Some agencies charge 10–20% of ad spend instead. These are market ranges, not our quote. Ask what’s included, because the setup and weekly search-term work are where results come from.

Cost	Typical Australian market range
Management fee	$500–$1,500 per month
Percentage model (alternative)	10–20% of ad spend
Ad spend, hot water test	From about $1,000 per month
Ad spend, emergency test	From about $2,500 per month

Good management for plumbers includes campaign setup, call tracking, weekly search-term reviews, negative keywords, schedule and bid changes, and a monthly report in plain English showing cost per lead and cost per booked job. Watch for long lock-in contracts and reports that only show clicks.

Ads stop the day you stop paying, so most plumbers run them alongside SEO and let organic rankings take over the cheaper calls over time. Our Google Ads service covers how we manage accounts, and Google Ads for tradies covers other trades. Work is month-to-month, with no lock-in.
