If you're a plumber thinking about running ads, you've probably asked yourself whether Facebook or Google is the better bet. They both promise to bring you more customers, but they work in completely different ways — and picking the wrong one can waste your money fast.
Here's the straightforward answer, based on how each platform actually works for plumbing businesses.
The Fundamental Difference: Intent vs Interruption
This is the most important thing to understand, and it explains almost everything about which platform works better for plumbers.
Google Ads show your business to people who are actively searching for a plumber. They've typed "plumber near me" or "emergency plumber Manchester" into Google. They have a problem right now and they want it fixed. That's intent — they're already looking for you.
Facebook Ads show your business to people who are scrolling through their feed looking at photos of their mate's holiday, cat videos, and news articles. They might own a home, they might live in your area, but they're not thinking about plumbing right now. That's interruption — you're hoping to catch their attention while they're doing something else.
For plumbers, this difference is enormous. Most plumbing work is reactive — something has gone wrong and needs fixing. The homeowner doesn't browse Facebook for a plumber. They grab their phone, search Google, and call the first result they trust.
When Google Ads Win (Most of the Time)
Google Ads are the better option for the majority of plumbing work. Here's why.
Emergency Work
This is where Google Ads are unbeatable. Someone's boiler has broken down in January. Their kitchen is flooding at 10pm. They're searching "emergency plumber" on their phone and they're going to call whoever appears first. There's no Facebook ad in the world that would reach this person at this moment.
Emergency plumbing keywords cost more per click, but the conversion rate is extremely high. The person calling isn't price-shopping — they need help now. One emergency callout can easily cover a week of ad spend. This is the bread and butter of advertising a plumbing business effectively.
Urgent Repairs
Not everything is a midnight emergency, but a lot of plumbing work is still urgent. A dripping tap, a slow drain, a toilet that won't flush properly. These homeowners search Google within a day or two of noticing the problem. Google Ads put you in front of them at exactly the right moment.
Local Search Dominance
Google Ads appear at the very top of search results — above the map, above the organic listings. Combined with a solid Google Maps presence, you can dominate the entire first page for plumbing searches in your area. That visibility is worth far more than a Facebook post that gets a few likes.
When Facebook Ads Actually Work for Plumbers
Facebook isn't useless for plumbers — but it works for a specific type of job. The key is planned work, where homeowners are in the early stages of thinking about a project, not reacting to an emergency.
Bathroom Renovations and Refits
A homeowner thinking about redoing their bathroom doesn't search Google on day one. They browse Pinterest for ideas, scroll Instagram for inspiration, and see what's in their Facebook feed. A well-targeted Facebook ad showing beautiful before-and-after photos of a bathroom you've renovated can catch their attention and plant your name in their mind.
Boiler Upgrades and Central Heating
Nobody replaces a working boiler on impulse, but plenty of homeowners know their boiler is old and unreliable. A Facebook ad in autumn, reminding people that winter is coming and offering a free quote on a new boiler, can generate genuine leads for planned replacement work.
New Build and Extension Work
Homeowners planning an extension or loft conversion need plumbing work as part of the project. They're typically in planning mode for weeks or months before they hire anyone. Facebook ads targeting homeowners who've recently engaged with renovation content can reach these people early in their decision-making process.
The Cost Comparison
Both platforms charge you based on competition, but the mechanics are different.
Google Ads charge per click. Plumbing keywords in the UK typically cost between two and eight pounds per click, depending on your area and the specific search term. Emergency keywords cost more. But because the person clicking has high intent, the conversion rate is good — a reasonable expectation is one enquiry for every five to ten clicks.
Facebook Ads charge per impression (how many people see your ad) or per click. Clicks are cheaper — often under one pound — but the conversion rate is much lower because the person wasn't looking for a plumber when they saw your ad. You might need 50 or 100 clicks to get one genuine enquiry.
When you work out the cost per actual job, Google Ads almost always win for standard plumbing work. Facebook can compete on cost for higher-value planned projects like bathroom refits, but only if your targeting is sharp and your ad creative is genuinely compelling.
For a broader picture of how social media compares to Google Ads for trades, the pattern holds across most trade businesses — not just plumbing.
What About Organic Social Media?
Before spending money on Facebook Ads, consider whether organic posting would work just as well. Sharing photos of completed work, posting in local community groups, and asking happy customers to recommend you in local Facebook groups costs nothing and builds your reputation over time.
Many plumbers get consistent referrals from local Facebook groups without spending a penny on ads. Someone posts "Can anyone recommend a plumber in [your area]?" and three previous customers tag you. That recommendation carries more weight than any ad.
The Honest Recommendation for Most Plumbers
If you can only choose one platform, choose Google. It reaches people who need a plumber right now, and that's the majority of plumbing work. The intent is there, the conversion rate is higher, and the cost per actual job is lower.
If you've already got Google covered — either through Google Ads for plumbers or strong organic rankings — then Facebook Ads can be a worthwhile addition for planned work like bathroom refits, boiler upgrades, and heating installations.
If budget is tight, put everything into Google. A well-optimised Google Maps listing, a fast mobile-friendly website, and a small Google Ads budget will outperform any amount of Facebook spending for a typical plumbing business.
