Growing a plumbing business isn't about working more hours or taking on every job that comes your way. It's about making the phone ring more often with the right kind of work — so you can be choosy about what you take on and charge what your time is worth.
Here are seven things that successful plumbing businesses do differently.
1. Get Visible on Google Maps
When a homeowner has a leaking pipe or needs a new boiler, the first thing most of them do is search "plumber near me" on their phone. The businesses that show up on Google Maps get the calls. The ones that don't exist as far as those customers are concerned.
Your Google Business Profile is free, and it's the single most important piece of your online presence. Make sure it's claimed, fully filled out, and has your correct phone number, address, service area, and business hours. Add photos of your van, your work, and your team.
Google uses your profile to decide whether to show you in the map results. A complete, active profile with recent reviews beats a bare-bones listing every time. If you haven't touched yours in months, that's the first thing to fix.
2. Collect Google Reviews From Every Job
Reviews are the difference between a customer calling you and calling the plumber listed above you. When someone sees two plumbers on Google Maps — one with 12 reviews and one with 85 reviews — they call the one with 85. It's that simple.
The key to getting more Google reviews is asking consistently. After every job, send a quick text with a direct link to your Google review page. Something like: "Thanks for today — if you've got a minute, a Google review helps us loads." Most happy customers will do it if you make it easy.
Aim for a steady flow rather than a big batch. Two or three new reviews every week signals to Google that you're active and reliable, which helps your ranking. A hundred reviews from last year with nothing since doesn't have the same effect.
3. Have a Professional Website
Your website is where people go to decide whether to call you. If you don't have one, or yours looks like it was built ten years ago, you're losing customers before they even pick up the phone.
A good plumbing website doesn't need to be complicated. It needs to clearly show what you do, where you work, how to contact you, and why people should trust you. Photos of real work, your Google review rating, and a phone number that's easy to tap on a mobile phone.
If you're wondering whether a website is really necessary, see our guide on whether tradespeople need a website. The short answer: yes, if you want to grow beyond word of mouth.
4. Run Google Ads for Emergency Work
Plumbing is one of the best trades for Google Ads because so much of the work is urgent. When someone's boiler has broken down on a cold night, they're not comparison shopping — they're calling the first plumber they find.
Google Ads put you at the top of search results for searches like "emergency plumber" or "boiler repair near me." You pay per click, so you only spend money when someone actually visits your website. With the right setup, every pound you spend on ads can come back several times over.
The key is targeting the right searches and the right area. You don't want to pay for clicks from people 30 miles away or people searching for DIY plumbing advice. Proper setup makes the difference between ads that pay for themselves and ads that drain your bank account.
5. Build a Brand People Remember
Most plumbing businesses look the same — a white van, a phone number, and a generic name. The ones that grow fastest are the ones that stand out.
Branding doesn't mean spending thousands on a fancy logo. It means being consistent and professional in everything a customer sees: your van, your uniform, your invoices, your website, your Google profile. When everything looks like it belongs to the same business, you look established and trustworthy.
Think about the plumber who turns up in a clean, branded van with a proper uniform versus the one who arrives in a plain white transit with no signage. The first one can charge more because they look like a business, not a bloke with a spanner. Customers pay more for the feeling of professionalism.
A strong brand also makes word of mouth more effective. When someone recommends you, the person they're talking to will look you up online. If what they find looks professional and established, they'll call. If it looks amateur, they might keep looking.
6. Upsell and Cross-Sell Existing Customers
The cheapest way to grow any business is to sell more to the customers you already have. In plumbing, that means looking for additional work on every job.
If you're fixing a leaking tap, check the age of the boiler. If you're installing a new bathroom, mention the option to replace old pipework while the walls are open. Not every customer will say yes, but enough will to make a meaningful difference to your revenue.
This isn't about pressuring people. It's about being helpful and proactive. "While I'm here, I noticed your boiler is getting on a bit — I can give you a quote for a replacement if you'd like" is good customer service, not a hard sell. Customers appreciate a plumber who spots problems before they become emergencies.
Keep a simple database of your customers and what you've done for them. A quick text once a year — "Hi, just a reminder your boiler service is due" — brings in easy, repeat work that costs you nothing to win.
7. Build a Referral System
Word of mouth is how most plumbing businesses get started, and it remains powerful. But relying on it alone isn't enough to grow consistently. The difference between hoping for referrals and having a referral system is the difference between luck and strategy.
A referral system means actively encouraging customers to recommend you. That could be as simple as saying at the end of every job: "If any of your neighbours or family need a plumber, I'd really appreciate you passing on my number." Some plumbers leave a few business cards. Others offer a small discount on the next job for every referral.
The point is to make it easy and give people a reason to remember you. Happy customers want to recommend good tradespeople — they just forget unless you remind them.
Combine this with a strong online presence and referrals become even more powerful. When someone hears your name from a friend, the first thing they do is Google you. If they find a professional website and 80+ positive reviews, you've won the job before you've answered the phone.
Putting It All Together
None of these seven strategies works in isolation. The real growth comes when they reinforce each other:
- Google Maps brings new people to your profile
- Reviews convince them to click through to your website
- Your website converts them into a phone call
- Great work leads to upsells and referrals
- Referrals check your online presence before calling
- The cycle repeats and compounds
The plumbing businesses that grow year after year are the ones that build this engine and keep it running. Each piece makes the others work better.
