KJM tops Which? Google and Checkatrade with near‑perfect scores
With over 750 public reviews and counting, discover why homeowners across Hampshire consistently rate KJM Group as their top choice for home improvements.
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 750+ 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 a snapshot of recent feedback from across Hampshire and Berkshire:
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 43 years of business and over 25,000 installations, absolute perfection every single time 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 genuine “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 randomly interview our past customers.
2. Checkatrade (9.87/10)
With over 370 reviews, our score here heavily 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 public feedback. With over 320 reviews, this high score proves consistency over decades, not just a lucky streak of happy customers.
Frequently Asked Questions
These scores are aggregates from independent platforms. We have absolutely no control over them. Customers leave feedback directly on Google, Which?, or Checkatrade. We cannot delete or edit these reviews, ensuring total transparency.
Our 4.9 rating exists because we actively 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.
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 exceptionally high “Tidiness” and “Reliability” scores you see on Checkatrade.
