Best Marketing Agency for Plumbers and Heating Engineers: A Buyer's Guide
The best marketing agency for a plumber or heating engineer understands urgent call-outs. It makes sure emergency calls are answered or returned fast, prepares your Google profile and ads for boiler season, shows your Gas Safe registration and real job photos, and keeps ads off when nobody can answer. Ask how they handle each.
Why do plumbers need a specialist approach?
Plumbing and heating enquiries are often urgent, and urgent customers ring the next number if you do not pick up. A leaking pipe or a dead boiler in January does not wait for a callback tomorrow. That makes speed of response and visibility in the Google map results more important than polished branding.
Demand is also seasonal. Heating breakdowns and boiler repairs pick up when the weather turns cold, while bathroom fits and planned installs are steadier. A good agency plans for this: more budget and more visible "boiler repair" content in autumn and winter, and a push on servicing and installs in the quieter months.
How should an agency handle emergency and after-hours calls?
It should test them first. Before any ad money is spent, the agency should ring your number at different times and send a test form, then tell you what a customer experiences. Typical fixes are simple: a voicemail greeting that says when you will call back, a text sent automatically after a missed call, a form that confirms receipt, and Google profile hours that match when you actually answer.
The ads must follow the same hours. If you do not offer 24-hour cover, ads should not run at 2am, and if you do, someone must answer. Our guide to missed calls shows how to work out what unanswered calls are costing you with your own numbers.
What trust signals should a plumber's marketing show?
Your Gas Safe registration comes first if you do gas work. By law, all gas engineers must be on the Gas Safe Register, and customers are told to check an engineer's ID card and the register before work starts. Make it easy: put your registration number on your website, Google profile and quotes, and explain that customers can check it.
After that, the strongest trust signals are real ones:
- Photos of your actual work, van and team, not stock images.
- Recent Google reviews that mention the job and the area.
- A clear price approach, such as a call-out fee or "fixed quote before we start", if that is how you work.
- The areas you cover and roughly how quickly you can attend.
An agency that suggests fake badges, stock photos of smiling engineers or invented review counts is putting your reputation at risk.
What should an agency do with your Google profile and reviews?
It should keep your profile accurate and active, because Google ranks local results on relevance, distance and prominence and says you cannot pay for a better local ranking. That means the right primary category (plumber, or heating contractor if that is your main work), every service listed, true hours, and new photos regularly.
For reviews, the agency should help you ask every customer, straight after the job, with a short link. Google's rules ban offering incentives for reviews or only asking customers you expect to be happy. A simple text the same evening works well: "Thanks for having us round today. If you were happy with the work, a quick Google review helps other people find us: [link]."
Can an agency run boiler service reminders for you?
Yes, and it is one of the cheapest sources of repeat work, but it must follow the rules. The ICO's soft opt-in lets you email or text existing customers about similar services if you got their details during a sale, and you gave them a clear chance to opt out when you collected them and in every message. Texts count as electronic mail under these rules. New contacts and bought lists are a different matter, and an agency offering to text a purchased list is a red flag. This is a general guide, not legal advice.
A good reminder is short and useful: "Hi, it's been about a year since we serviced your boiler. Reply YES and we'll call to book, or STOP to opt out."
How do you compare agencies for a plumbing business?
Ask each agency the same questions and score the answers.
| Question | Good answer | Weak answer |
|---|---|---|
| What would you check first? | Calls, missed calls, forms, Google profile hours | "Your branding" |
| How do you plan for winter? | Budget and content shift towards repairs and breakdowns | Same plan all year |
| When will the ads run? | Only when someone can answer or call back fast | "24/7 for maximum reach" |
| How do you track results? | Calls and forms tracked, cost per booked job reported | Clicks and impressions only |
| What results can you promise? | Realistic timescales, no guarantees | "Page one guaranteed" |
| Who owns the accounts? | You do, we get manager access | "We keep the account" |
Google's own guidance says no one can guarantee a number one ranking. If you want the wider checklist that applies to all trades, see our guide to choosing a marketing company for tradespeople, and for ads specifically, Google Ads for tradespeople.
Where Oski Marketing fits
Oski Marketing works with plumbers and heating engineers in London and the South East. We start with the 9pm problem: what happens when someone with a leak rings or messages you after hours. Then we fix the profile, the website and the response set-up, and run Google Ads and content timed to the heating season. Google Ads management is from £600/month plus ad spend paid directly to Google, on a rolling contract, and you keep ownership of the account.
We are not the right fit if you want a fixed number of leads promised, if you need a national call-centre operation across many branches, or if you want to text people who have never been your customers.
What to do this week
- Ring your own number after 6pm and check the voicemail greeting says when you will call back.
- Add your Gas Safe registration number to your website footer and Google profile description.
- Set your Google profile hours to match when you really answer, including bank holidays.
- Upload five photos of recent jobs to your profile.
- Send your review link to every customer from the last fortnight.
Frequently asked questions
How do plumbers get more customers?
Most plumbing work comes from people searching on Google or asking for a recommendation when something has gone wrong. Make sure you show up in the map results, answer or call back fast, and look trustworthy with real photos, reviews and your Gas Safe details. Then ask every happy customer for a review and keep their details for service reminders, within the rules.
Are Google Ads worth it for a plumber?
They can be, especially for urgent jobs like leaks and boiler breakdowns, as long as the ads only run where and when you can actually attend and every call is tracked. Ads that run at 2am when nobody answers simply pay for missed calls. Start small, track calls, and judge on cost per booked job.
Can a plumber text customers to remind them about boiler servicing?
Usually yes, for existing customers, under the ICO's soft opt-in, if you collected their details during a job, the reminder is about similar services, and you gave them a clear chance to opt out when you took their details and in every message. New contacts need consent first.
What should a plumber's website show?
Your phone number at the top on mobile, the areas you cover, the jobs you do and roughly how quickly you can attend, your Gas Safe registration if you do gas work, real job photos and recent reviews. Keep the contact form short and test it yourself.
