For plumbing Google Ads, A$40–A$120 per lead is a useful starting range for planning. The jobs you want, the suburbs you cover and the way your team handles enquiries all affect the result.
This guide shows how to use that range, what different budgets could support and which details to review before increasing spend. It also draws on plumbing campaign work for Aussie Plumbing, Alliance Plumbing and Aussie Leak Detect.
What does a plumbing lead cost on Google Ads in Australia?
For plumbing, use A$40–A$120 per Google Ads lead as a planning range. Blocked drains, hot water, leaks and emergency call-outs have different demand and job values. Your service area, competition and enquiry handling affect where the campaign sits within that range. Figures are ad spend per lead on Google Ads, before GST and our management fee. A lead is a phone call or an enquiry form.
Use the range to prepare a budget, then replace it with the cost of qualified enquiries from your own campaign. A hot water installation, an emergency repair and a specialist leak investigation have different values and booking processes.
| Planning question | What to use |
|---|---|
| What should we allow per lead? | A$40–A$120 in ad spend as a starting range. |
| What counts as a lead? | A recorded phone call or submitted enquiry form. Keep phone-button taps separate. |
| What should we judge next? | Whether the enquiry is for a service you provide, in an area you cover, and whether it becomes booked work. |
| Are fees included? | GST and management fees sit outside this ad-spend calculation. |

What changes a plumbing campaign’s cost per lead?
A clear campaign brief starts with the work the business wants to book. Those choices matter as much as the budget.
| Decision | What to check |
|---|---|
| Services | Separate blocked drains, hot water, general repairs and specialist work where the search intent and landing page differ. |
| Service area | Choose suburbs the crew can reach reliably. Account for travel time, existing jobs and where vehicles start the day. |
| Availability | Match emergency messaging to the hours you can answer and attend. Use quote requests for planned work. |
| Landing pages | Answer the actual service question, show relevant work and make calling or requesting a quote straightforward on a phone. |
| Measurement | Count calls and forms consistently, separate duplicate enquiries and record which jobs are booked. |
Emergency demand can be competitive, and planned work may involve several quotes. Neither is automatically cheaper. Compare the services using enquiry quality, booking rate and job value together.
Our Google Ads service for plumbers covers how we organise these decisions. If the website needs work first, see our plumbing website projects.
What does a monthly budget of A$5,000 to A$20,000 buy a plumber?
The table divides each budget by the two ends of the A$40–A$120 planning range. It shows the arithmetic for enquiries, not a promised volume of jobs.
| Monthly ad spend | Illustrative monthly leads |
|---|---|
| A$5,000 | About 42–125 |
| A$10,000 | About 83–250 |
| A$20,000 | About 167–500 |
Check that your service area has enough relevant demand and that the team can handle the enquiries. A larger budget does not guarantee the same cost per lead: the available searches, competition and service mix can change as the campaign grows.
To estimate jobs, apply your own enquiry-to-booking rate. Then compare the likely job value with labour, materials, travel, ad spend and management costs. We generally recommend A$5,000 a month in ad spend for most businesses, with the final plan based on the work and market you can support. Our trade marketing budget guide explains the calculation.
A missed call is the most expensive thing in a plumbing account, because Google has already charged for it.
Are plumbing leads mostly phone calls or forms?
Mostly calls. In SoudCoh's research sample of plumbers, 75% of enquiries were phone calls and 25% were website forms, and 74% of ad clicks came from mobile phones. A plumbing campaign is, in practice, a phone-call business run through a mobile screen.
That changes where the money is won or lost:
- Call tracking has to be right before anything else. Google Ads can count calls from the ad itself and calls to a tracked number on your website, and it only counts a call once it passes a minimum length you set. If calls are not being recorded, cost per lead looks far worse than it is and the bidding optimises toward the wrong thing.
- The phone number and call button must be impossible to miss on a phone. See what that means in our guide to a trade website that converts calls and forms.
- Forms still matter for planned work. Quotes for hot water systems, renovations and commercial maintenance often come through forms, sometimes after hours. A short form with the suburb and the job type gives the office what it needs to call back.
What moved lead costs and conversion for real plumbing businesses?
Three plumbing businesses from SoudCoh's case studies, each compared with itself over time.
| Business | Measured improvement | Compared over | Clicks that became an enquiry | Enquiries by phone |
|---|---|---|---|---|
| Aussie Plumbing | 1.8× ad spend, with enquiries up 2.1×, so each enquiry cost less | Latest full month compared with the first full month | 11.9% | 76% |
| Alliance Plumbing | 1.8× ad spend, with enquiries up 2.1×, so each enquiry cost less | Best full month compared with the first full month | 21.6% | 81% |
| Aussie Leak Detect | 16.4% → 23.5% click-to-enquiry rate | Latest full month compared with the first full month | 21.1% | 84% |
Read the improvement column in two ways. Where ad spend and enquiries rise together, the account grew without giving back its efficiency: each extra dollar still bought enquiries close to the earlier rate. A lower cost per enquiry means the same ad spend generated more enquiries. A higher click-to-enquiry rate shows more clicks becoming enquiries; review click costs and booked-job outcomes alongside it. When spend rises faster than enquiries, cost per lead drifts up, and the test is whether the extra jobs are worth it.
The work behind those numbers followed one playbook, applied to what each account needed: campaigns built by job and by suburb, ads matched to the job searched, regular exclusion of searches that would never book, and calls measured separately from forms. Aussie Plumbing took 76% of its enquiries by phone and Aussie Leak Detect 84%, which is why call handling sits alongside the ads in every review. None of these results is a forecast for another business.
How do you bring a plumber's cost per lead down?
We review enquiry costs alongside lead quality and booked work, so the campaign reflects the jobs your business wants. Start by reviewing the details that affect whether the campaign brings suitable enquiries:
- Confirm every call and form is counted once. Duplicated or missing leads distort cost per lead more than any bid change.
- Split campaigns by job and by suburb. One ad for “plumber” cannot speak to a blocked drain in one suburb and a hot water failure in another.
- Send each ad to a matching page. A blocked-drain search should land on a blocked-drain page, not the home page.
- Review search terms weekly. Exclude DIY, job-seeker, supplier and out-of-area searches as they appear.
- Answer the phone, or pause the ads. Match the ad schedule to real call cover.
- Judge it over months, not weeks. In SoudCoh's research sample, a new campaign's second month typically brought 1.9 times as many enquiries as its first. Volume builds first, and efficiency comes from the work above. Our guide to how long Google Ads takes to get leads has the full ramp.
If you would rather have this run for you, our page on Google Ads for plumbers shows how we set up plumbing campaigns, and our lead generation for tradies covers the website, tracking and follow-up around the ads. When the website is the weak link, we build websites for plumbers with service and suburb pages for the campaigns to land on.
Plan against the typical cost per lead for your trade, then measure your own lead-to-job rate to turn it into jobs.
What happens after the lead? The won-job data
Cost per lead is half the picture. SoudCoh's analysis of won-job records follows each plumbing enquiry from Google Ads to the job the business marked as won, valued at the agreed price. Four findings matter most when you read a lead cost:
- About 1 in 5 enquiries became a won job for the typical plumbing business, counting wrong numbers and enquiries that were never updated.
- Won jobs were worth about 2.5× the ad spend across the businesses. That is job value, not profit.
- Searches naming a suburb were won 1.5× as often as other searches, which is how a suburb campaign can earn a dearer click.
- The biggest tenth of jobs carried about 50% of won revenue, so the cheapest lead and the most valuable lead are rarely the same one.
Judge a plumbing campaign on what its leads turn into, not only on what they cost. The full analysis is in what turns a plumbing search into a won job.
Common questions about plumbing lead costs
How much does a plumbing lead cost on Google Ads in Australia?
For plumbing, use A$40–A$120 per Google Ads lead as a planning range. Blocked drains, hot water, leaks and emergency call-outs have different demand and job values. Your service area, competition and enquiry handling affect where the campaign sits within that range. The range covers ad spend before GST and management fees. Review it alongside the proportion of enquiries that become booked jobs.
How many leads will A$5,000 a month get a plumber?
A$5,000 divided by the A$40–A$120 range gives about 42–125 leads. This illustrates the budget calculation rather than forecasting demand. Services, suburbs, competition, landing pages and call handling can change the actual result.
Why are most plumbing leads phone calls?
In SoudCoh’s research sample, 75% of recorded plumbing enquiries were calls. A conversation can help a customer explain a problem, confirm availability and arrange the next step. Make calling straightforward and provide a useful form for people who prefer to send details.
Is cost per lead the same as cost per job?
No. Cost per lead counts every recorded call and form, including price shoppers and jobs outside your area. To find cost per booked job, divide ad spend by the jobs won from those leads. Your own lead-to-job rate decides that figure, so track it alongside cost per lead.
Is there one average cost per lead for all trades?
There is no single cost per lead across industries. A removalist lead and a commercial cleaning lead are different jobs with different values, so the figures are given industry by industry. Use the range for your industry, then compare it with your own enquiry quality, booking rate and job value.
Do agency fees count in these cost-per-lead figures?
No. Figures are ad spend per lead on Google Ads, before GST and our management fee. A lead is a phone call or an enquiry form. Management fees are a separate cost. SoudCoh's fees are not published because every engagement is scoped around the services, areas and volume of work a business wants.
Questions and answers
Should a plumber run ads outside business hours?
Only when someone can answer. Urgent plumbing searches happen at night and on weekends, but an unanswered call still costs the click. Match the ad schedule to real call cover and extend it as cover improves.
What should I bring to a plumbing cost-per-lead review?
Bring the services you want more of, the suburbs you cover, recent enquiry numbers and how many became jobs. These details help turn a broad planning range into a practical budget and review process for your business.
