Look at the plumbing and heating businesses that dominate local search in any UK town, and you will find a consistent pattern: they have significantly more reviews than their competitors. Not just slightly more - often ten or twenty times more. This is not an accident. These businesses have built systems that consistently generate reviews, and those reviews compound over time into a dominant local reputation.
In our audit data, the businesses with the strongest online reputations - those with 100 or more Google reviews and an average rating above 4.7 - all had one thing in common: they asked for reviews systematically, not occasionally. The businesses with fewer reviews were not delivering worse service; they were just not asking.
The Psychology of Review Requests
Most customers who have had a positive experience with a trades business would be happy to leave a review if asked. The problem is that the thought of leaving a review simply does not occur to most people unless they are prompted. A customer who had a great boiler service will go about their day, and by the time they think about leaving a review - if they ever do - the moment has passed.
The solution is to ask at the right moment, in the right way, with as little friction as possible. The right moment is within 24 hours of completing the job, while the experience is fresh and the customer is still in the warm glow of a problem solved. The right way is a direct, personal request - not a generic email blast. And the minimum friction approach is a direct link to your Google review page, so the customer does not have to search for your business.
Building the System
An effective review generation system has three components:
Component 1: The in-person ask. Train your engineers to mention reviews at the end of every job. A simple, natural script works well: "If you're happy with the work today, it would really help us if you could leave us a quick Google review - I'll send you a link." This personal ask, from the engineer who just did the work, is the most powerful trigger for a review.
Component 2: The automated follow-up. Within 24 hours of job completion, send an automated SMS or email to the customer with a direct link to your Google review page. The message should be brief, personal, and specific: "Hi [Name], thanks for choosing [Business Name] for your boiler service today. If you're happy with the work, we'd really appreciate a quick Google review - it takes less than a minute: [direct link]."
Component 3: The direct link. The single biggest barrier to leaving a review is finding the right place to leave it. A direct link to your Google review page removes this barrier entirely. To get your direct review link, go to your Google Business Profile, click "Get more reviews," and copy the link provided. Shorten it with Bitly or a similar service for use in SMS messages.
Automating the Process
The most effective review generation systems are automated. When a job is marked as complete in your scheduling or CRM system, an automated message is triggered and sent to the customer. This ensures that every customer receives a review request, regardless of how busy the office is or whether the engineer remembered to mention it.
InstallerOS includes automated review generation as part of its customer communication system. When a job is completed, the system automatically sends a personalised review request to the customer, with a direct link to the Google review page. The timing, message content, and follow-up sequence are all configurable.
What Not to Do
A few important cautions. Never offer incentives for reviews - discounts, free services, or any other reward in exchange for a review violates Google's policies and can result in your listing being penalised or removed. Never ask for reviews in bulk from existing customers - a sudden spike in reviews looks suspicious to Google and may be flagged as inauthentic. And never ask unhappy customers for reviews - if you sense that a customer is not fully satisfied, resolve the issue first.
