Most plumbers who ask what Google Ads costs want one number. The honest answer is that there are three: what you pay per click, what you pay per enquiry, and what you pay per job that actually gets booked. The first is set by the auction. The other two are set mostly by you: by which searches you pay for, how good your landing page is and how quickly you answer the phone.
This guide walks through all three with published 2026 UK figures, then turns them into a monthly budget you can sanity-check against your own invoices.
Quick answer: Published 2026 UK estimates put emergency plumber clicks at roughly £4 to £12 and boiler installation clicks at £8 to £20, with London and big cities often 30 to 60% higher. A first test budget of £400 to £800 a month is typical for an emergency plumbing campaign. What you get back depends far more on lead handling than on the click price.
What does a Google Ads click cost for a plumber?
Google does not publish a price list. Every click is priced in a live auction, so the cost moves with your area, the time of day, how many competitors are bidding and how relevant Google thinks your ad and page are. What we can do is look at published estimates and treat them as a starting range.
| Type of plumbing search | Typical UK CPC (2026 estimate) | Typical first invoice |
|---|---|---|
| Emergency plumber, burst pipe, leak | £4 to £12 | £150 to £300 |
| Boiler installation / replacement | £8 to £20 | £2,500 to £4,000 |
| Drain unblocking | £2 to £7 | £150 to £600 |

Two things push plumbing clicks up. The first is urgency: someone with water coming through the ceiling rings one of the first two or three numbers they see, so every plumber in town wants to be at the top. The second is location. Agency estimates put London clicks 15 to 30% above the UK average (Whito, 2026), and some trade benchmarks put big-city trade clicks 30 to 60% higher. A Leicester plumber and a Croydon plumber bidding on the same words are not paying the same price.
Why the click price is the least useful number
A £9 click that turns into a £280 leak repair is cheap. A £3 click from someone who wanted a plumbing apprenticeship is expensive. That is why we spend very little time trying to push the CPC down and a lot of time controlling which searches the budget is allowed to buy.
From cost per click to cost per lead
Cost per lead is simply your cost per click divided by the share of clicks that become a call or form. Trade2Base puts click-to-call rates for emergency plumbing at 8 to 15%. Here is what that range does to the cost of an enquiry:
| CPC | 8% of clicks enquire | 12% enquire | 15% enquire |
|---|---|---|---|
| £4 | £50 per lead | £33 | £27 |
| £8 | £100 | £67 | £53 |
| £12 | £150 | £100 | £80 |
Look down the right-hand column and across the rows. Moving from 8% to 15% conversion roughly halves your cost per lead, at the same click price. A clear page, a tap-to-call button that works and an ad that promises what you actually do will usually save more money than any bid change.
For a wider comparison, the 2026 WordStream and LocaliQ benchmarks, based on 13,474 US search campaigns, put the median cost per lead for home and home improvement at $90.92 with an 8.05% conversion rate. They are US figures, so treat them as a sense check rather than a UK target.
From cost per lead to cost per booked job
Not every lead is a job. Some are out of area, some want a price for work you do not do, and some ring three plumbers and book whoever turns up first. The number that tells you whether ads make money is cost per booked job: spend divided by jobs you actually booked from ads.
Illustrative example, not a benchmark.
If those six jobs average £220, the plumber spent £1,000 to invoice about £1,320. That is thin. If two of them were boiler swaps at £3,000 each, the same month looks very different. This is why we push plumbing clients to record the job value against each enquiry, even in a spreadsheet. Without it, you are judging the campaign on the wrong number.
A sensible target
Trade2Base suggests aiming for a cost per booked job of around 10 to 15% of job value. For a £250 emergency repair that is £25 to £38, which is hard to hit on emergency keywords in a competitive city. For a £3,000 boiler installation it is £300 to £450, which most well-run accounts can reach. In practice many plumbers accept a higher cost on emergency work because a good first visit turns into servicing and bigger jobs later.
How much should a plumber spend on Google Ads each month?
Work backwards from the jobs you can actually take on. If your diary has room for eight extra jobs a month and you book about half of real leads, you need roughly 16 real leads. At a cost per lead of £40 to £80 that is £640 to £1,280 of ad spend.
| Extra booked jobs wanted | Real leads needed (50% booking) | Ad spend at £40 CPL | Ad spend at £80 CPL |
|---|---|---|---|
| 4 | 8 | £320 | £640 |
| 8 | 16 | £640 | £1,280 |
| 12 | 24 | £960 | £1,920 |
Published guidance puts a minimum test budget for trades at £300 to £500 a month and a typical emergency plumber budget at £400 to £800 (Trade2Base, 2026). Below about £300, Google's bidding has too little data to learn from and a single expensive day can wipe out the week.
Remember that ad spend and management fees are separate. Ad spend goes to Google. If you use an agency, its fee covers the build, the weekly search-term reviews and the reporting.
Where plumbing budgets usually leak
Paying for searches you cannot serve
"Plumber jobs", "plumbing course", "how to fix a dripping tap", brand names of products you do not fit and towns 40 minutes away. Check the search terms report every week and add negative keywords. This is boring and it is where most of the savings are.
Mixing emergency and planned work
An emergency leak and a bathroom refit have different click prices, different conversion rates and different job values. In one campaign, the cheap planned searches hide how expensive the emergency ones are, or the other way round. Split them so each has its own budget and its own cost per booked job.
Missed calls
You pay for the click whether or not you answer. Research by Moneypenny found that a third of micro businesses did not answer incoming calls, and 69% of callers who reached voicemail hung up without leaving a message. For a sole trader under a sink, that is a real risk. Call tracking will show your missed-call rate; a call answering service or an instant text-back can cut it.
Counting every call as a conversion
If a 6-second wrong number counts as a conversion, Google's bidding learns to find more of them. Set a minimum call length for call conversions (many accounts use 60 seconds) and, once you have the volume, import booked jobs from your job management tool as offline conversions.
Should plumbers use Local Services Ads as well?
Plumbers are one of the categories Google lists for Local Services Ads. You pay per lead rather than per click, and published UK estimates put LSA leads at around £15 to £50 depending on trade and area, with 40 to 60% of those leads becoming booked jobs (Trade2Base, 2026). LSAs suit urgent, local, phone-led work and need verification first. Search Ads give you more control over which jobs and which postcodes you pay for. Many busy plumbers run both and compare cost per booked job across the two. We compare them in detail in Local Services Ads vs Google Search Ads.
A simple monthly check
- Export calls and forms for the month.
- Mark each one: real lead, booked, not suitable or missed.
- Work out cost per lead and cost per booked job by campaign.
- Add negatives from the search terms report.
- Move budget towards the campaign with the lowest cost per booked job and enough capacity behind it.
It takes about an hour and it changes how you see the spend. For the full method, read how to calculate your real cost per booked job, or see how we run Google Ads for plumbers and gas engineers.

How much should a plumber spend on Google Ads per month?
A first test budget of £400 to £800 a month is common for emergency plumbing. Work backwards from the extra jobs you can take on and your booking rate.
