KJM tops Which? Google and Checkatrade with near‑perfect scores
In an industry often plagued by pushy sales tactics and “here today, gone tomorrow” installers, trust is the most valuable currency we have.
At KJM Group, we don’t just claim to be reliable; we let the data speak for itself. With over 700+ public reviews and award-winning status, we are proud to announce we have maintained near-perfect scores across the “Big Three” independent review platforms.

Real Customer Voices
Scores are great, but stories are better. Here is what our customers have been saying this month:
Why “Near-Perfect” Matters More Than “Perfect”
You might notice we aren’t shouting about a “5.0” or “10/10” everywhere. Why? Because in 42 years of business and over 25,000 installations, perfection is impossible. Real construction involves weather delays, manufacturing hiccups, and human elements.
A 4.9/5 rating is actually more trustworthy than a flat 5.0. It shows we are real. It shows that on the very rare occasion something isn’t 100% right, we stay until it is resolved. That is the difference between a “sales company” and a “service company.”
The “Big Three” Breakdown
1. Which? Trusted Traders (4.9/5)
This is the gold standard. Unlike other schemes where you simply pay to join, Which? assesses us. Their assessors look at our financial health, our administrative procedures, and interview our past customers randomly.
2. Checkatrade (9.87/10)
With over 360 reviews, our score here reflects the “on-site” experience. The Reliability and Tidiness scores (9.92 and 9.90 respectively) are what homeowners truly care about. They confirm that our fitters turn up on time, do the job well, and clean up after themselves.
3. Google Reviews (4.9/5)
Google reviews are the most unfiltered source of feedback. With over 250 reviews, this high score proves consistency over decades, not just a lucky streak.
Frequently Asked Questions
How are these scores calculated?
These scores are aggregates from independent platforms. We have no control over them. Customers leave feedback directly on Google, Which?, or Checkatrade. We cannot delete or edit these reviews, ensuring total transparency.
What happens if I am not happy?
Our 4.9 rating exists because we solve problems. We have a dedicated after-sales service team. If an issue arises—whether it’s a stiff handle or a draught—we return to rectify it. Our 10-year warranty is backed by our 40+ year history of honouring our promises.
Do you use sub-contractors?
The vast majority of our installations are carried out by our own employed teams or long-standing partners who work exclusively to KJM standards. This allows us to maintain the high “Tidiness” and “Reliability” scores you see on Checkatrade.
