The Problem With Word of Mouth Alone
Every plumber knows the feast-or-famine cycle. Some weeks your phone does not stop ringing. Other weeks it is silent. Word of mouth is the foundation of most plumbing businesses, and it works — until it does not. You cannot control when people recommend you. You cannot scale recommendations. And you are invisible to everyone outside your existing network.
The plumbers who grow consistently — the ones who always have work booked two to three weeks ahead — are doing something different. They are not spending thousands on Facebook ads or Google PPC. They are using free tools and simple strategies that make them visible to customers who are already searching for a plumber.
Here are five things you can do this week, without spending any money, to start getting more calls.
1. Set Up and Optimise Your Google Business Profile
This is the single most impactful thing a plumber can do for free. When someone searches "plumber near me" or "emergency plumber [your town]," Google shows a map with three businesses. Those three businesses get the majority of clicks and calls. Your Google Business Profile is how you appear there.
If you do not have one, go to business.google.com and claim your listing. It takes 20 minutes. If you already have one, optimise it:
- Complete every field: Business name, address, phone number, website, hours, service area. Google ranks complete profiles higher than incomplete ones
- Choose the right category: "Plumber" as primary, then add secondary categories like "Water Heater Installation Service" or "Drain Cleaning Service"
- Add photos: Photos of your van, your work (before/after), your team. Profiles with photos get 42% more requests for directions and 35% more clicks to websites
- Post weekly updates: Completed jobs, seasonal tips ("How to prevent frozen pipes this winter"), special offers. Google rewards active profiles
2. Get Google Reviews — And Respond to Every One
Reviews are the most powerful trust signal for local service businesses. A plumber with 40 reviews and a 4.8-star rating will get more calls than a plumber with 3 reviews, regardless of how good either of them actually is. Perception drives decisions.
How to get more reviews:
- Ask at the right moment: Right after you have fixed a problem and the customer is relieved and grateful. "Really glad we got that sorted — if you have a moment, a Google review would mean a lot to a small business like ours"
- Make it easy: Create a direct link to your Google review page and text it to customers after the job. The fewer clicks, the more reviews you get
- Respond to every review: Thank positive reviewers by name. Address negative reviews professionally and offer to resolve the issue. Google and potential customers both notice when a business engages with reviews
Aim for 15+ reviews as your first milestone. After that, keep building — there is no upper limit, and recency matters.
3. Build a Simple Website (It Does Not Need to Be Fancy)
A plumbing website does not need to win design awards. It needs to do three things: tell people what you do, where you work, and how to contact you. That is it.
What to include:
- Your name, phone number (clickable on mobile), and service area
- A list of services: boiler installation, emergency repairs, bathroom fitting, drain unblocking, etc.
- A few photos of your work
- Your Google reviews or testimonials
- Your accreditations: Gas Safe registration number, any certifications
A basic professional website can be set up for £500–£1,000. The return on investment is immediate — one additional boiler installation from a website enquiry (worth £2,000–£4,000) pays for the website several times over.
4. Use Social Media the Right Way
Most plumbers either ignore social media or use it wrong. You do not need to become an influencer or post every day. You need to post the right content occasionally.
What works for plumbers on social media:
- Before/after photos: A blocked drain cleared, a new bathroom installed, a boiler replacement. These are visually satisfying and demonstrate competence
- Short tips: "How to find your stopcock before you need it" or "3 signs your boiler needs servicing." Helpful content gets shared
- Behind-the-scenes: Your van setup, tools of the trade, a day in the life. People like seeing the human side of trade businesses
- Completed job posts: "Just finished a full bathroom refit in [town]. Thanks to the homeowner for trusting us with the project." Tag the location
Post two to three times per week on Facebook and Instagram. Use local hashtags (#plumber[yourtown], #localbusiness). Join local Facebook community groups and answer plumbing questions — do not sell, just be helpful. The work follows.
5. Ask for Referrals Systematically
Word of mouth is powerful, but most plumbers leave it to chance. Make it systematic:
- After every job: "If you know anyone who needs a plumber, I would really appreciate you passing on my number"
- Leave business cards: Leave two cards with every customer — one for them, one to pass on
- Partner with related trades: Electricians, builders, tilers, and kitchen fitters all encounter customers who need plumbing work. Build referral relationships where you send work to each other
- Offer a referral incentive: "Refer a friend and get £20 off your next callout." Small incentives drive big results
What Not to Do
- Do not pay for leads from aggregator sites unless you have exhausted free channels first. Sites that sell the same lead to five plumbers create a race to the bottom
- Do not ignore online reviews. A 3-star rating with no responses looks worse than a 4-star rating with thoughtful replies to every review
- Do not undercut on price to win work. Compete on trust, reliability, and professionalism — not on being the cheapest
The Compound Effect
None of these strategies produces overnight results. But they compound. A Google Business Profile attracts reviews. Reviews attract clicks. Clicks drive calls. Calls become customers. Customers leave more reviews and refer their friends. A simple website captures the people who search for you by name after a recommendation.
Six months from now, the plumber who implements these five strategies will have a steady pipeline of inbound enquiries. The plumber who does nothing will still be waiting for the phone to ring.
