The short answer
Ask shortly after the job is finished and the customer has confirmed everything works, send a direct Google review link in a short message, add a review QR code to invoices, follow up once at most, and automate the steps as job volume grows. Always ask for an honest review, never for five stars.
- Ask once the customer knows the fix worked.
- A direct review link and a short WhatsApp message beat asking customers to search.
- One polite reminder, no incentives and no requests for five stars.
01Ask immediately after the job is completed
For a plumbing company, a Google review is more than a nice comment. It gives potential customers a reason to trust you before they pick up the phone.
When someone has a leaking pipe, a broken boiler or an overflowing toilet, they rarely have time to research ten different contractors. They search Google, compare a handful of local businesses and make a decision.
Your reviews can influence that decision.
The challenge is getting customers to leave them. Most satisfied customers are happy to move on once the problem is fixed. Unless you make reviewing easy, they may never think about it again.
Here are seven ways to build review requests into your plumbing business without creating more administration.
Timing matters.
A customer who has just had their heating restored or a leak repaired is likely to remember the experience clearly. Three weeks later, your request may feel unexpected.
The best time to ask is usually shortly after the work has been completed and the customer has had an opportunity to confirm everything is working.
For an emergency repair, that could be later the same day. For a bathroom installation or major plumbing project, it may make more sense to wait until the final walkthrough.
The goal is to make the request a natural part of the customer journey.

Don't ask customers to search for your business and find the review button themselves.
Give them a direct link to the review form for your Google Business Profile.
You can obtain your review link through your Google Business Profile's review-request options. Once you have it, save it somewhere your office staff and engineers can access.
A direct link removes unnecessary steps and makes it easier for customers to respond.
03Use a short WhatsApp message
For customers who have agreed to receive relevant WhatsApp communications, a brief message can be a convenient way to request feedback.
Hi Sarah, thanks for choosing us to sort out the leak today. We hope everything is running smoothly. If you have a minute, we'd really appreciate an honest Google review about your experience. [Google review link] Thanks again, The team at [Business Name]
Notice that the message asks for an honest review, not specifically a five-star review.
That distinction matters. Google prohibits practices that selectively solicit positive reviews or discourage negative feedback.
04Give engineers a simple review-request process
Your engineers are often the only people customers meet.
Make review requests part of the job-completion checklist:
- Confirm the work is finished.
- Explain any aftercare instructions.
- Tell the customer they'll receive a review link.
- Record that the job is complete so the request can be sent.
Avoid asking engineers to pressure customers into leaving reviews while they're standing in the kitchen.
A friendly mention followed by a convenient message is generally a better customer experience.
05Put a Google review QR code on invoices
Printed invoices, service cards and maintenance documents are useful places for a review QR code.
A customer can scan the code and open your review link directly.
This is particularly helpful when customers prefer not to receive additional messages.
You can create a printable code using Ranknua's free Google Review QR Code Generator.
Test the code with a phone before adding it to printed materials.
06Follow up once, not endlessly
Customers are busy. A single polite reminder may help if someone missed the original request.
Hi Sarah, just following up on our recent plumbing visit. If you'd like to share your experience, here's our Google review link: [link]. Thanks for your time.
Avoid repeated reminders, guilt-inducing language or incentives in exchange for reviews.
The customer should always feel free to ignore the request.
07Automate the process as your business grows
If you're completing two jobs a week, manually sending review requests may be manageable.
If you're completing 15 jobs a day across several engineers, it's easy to forget.
A repeatable workflow can help:
- The job is marked complete.
- The customer's contact details are confirmed.
- A review request is sent through an appropriate, permitted channel.
- A follow-up is scheduled where appropriate.
- New reviews are tracked.
The workflow doesn't need to be complicated. It needs to be consistent.

08Common mistakes plumbing businesses should avoid
Only asking happy customers
Google's policies prohibit selectively requesting positive reviews. Give customers a fair opportunity to share their genuine experience.
Offering discounts for reviews
Don't offer money, discounts, free services or other incentives in exchange for Google reviews.
Asking for five stars
Ask for an honest review, not a particular rating.
Forgetting to respond
A thoughtful response shows prospective customers that your business pays attention to feedback.
Keep responses professional and avoid sharing private job details.
09Make review requests part of every completed job
The most effective review process is one your team can follow consistently.
Start with a direct Google review link, a simple message and a clear job-completion workflow. Once those basics are working, consider automating the repetitive steps.

Frequently asked questions
How many Google reviews should a plumbing company have?+
There is no universal target. A small plumbing company serving one town will face different competition from a large contractor covering an entire city. Compare your profile with relevant local competitors and focus on building a steady flow of genuine reviews.
Should plumbers ask for reviews after emergency callouts?+
Yes, provided the request is appropriate and the customer is not being pressured. Waiting until the immediate emergency has passed is usually sensible.
Can plumbing companies automate Google review requests?+
Yes. A business can use job-completion information to trigger requests, provided its messaging practices comply with applicable privacy, consent and platform requirements.
