KJM Group Wins Which? Trusted Trader of the Month (Aug 2026)
Putting customers first with absolute cost transparency, zero-pressure sales, and dedicated aftercare results in a worthy second-time win.
We are absolutely thrilled to announce that KJM Windows and Conservatories has been awarded the prestigious title of Which? Trusted Trader of the Month for August 2026 Which.co.uk. Having previously secured this honour in February 2024, this second win serves as a testament to our team’s unwavering commitment to quality, community, and consumer trust. You can read the full official interview and judges’ comments on the Which? website.
Our “No-Pressure” Promise
The judges highlighted our clear, upfront pricing model. We completely reject the gimmicky buy-one-get-one-free offers and time-limited discounts that plague the industry.
Community Investment
We actively give back. Sponsoring the 2026 Andover Soapbox Derby allowed us to keep the event free for over 3,500 spectators while raising £6,000 for a local charity.
Over 40 Years of Doing Things the Right Way
Founded in 1982, KJM has steadily grown into a dedicated team of around 40 builders, installers, and office staff. Despite our growth across Hampshire, London, Surrey, Berkshire, Dorset, and Wiltshire, our founding philosophy remains completely unchanged.
As I mentioned to the Which? judging panel during our interview: “The ‘why’ has always remained the same: to provide high-quality home improvements without the high-pressure, hard-sell tactics our industry is unfortunately known for. We wanted to build a business rooted in genuine customer service, where honesty and transparency come first.”
A Team You Can Trust in Your Home
One of the core reasons we have maintained near-perfect ratings across Which?, Google, and Checkatrade is our incredible staff loyalty. We deliberately employ our own, highly-trained fitting teams rather than relying heavily on sub-contractors. Many of our team members have been with us for decades, guaranteeing the highest standard of workmanship on every single job.
Over 80% of our current installations come directly from returning customers or word-of-mouth recommendations. For us, this is the ultimate source of pride and proof that doing things the right way pays off.
Rejecting the “Hard Sell”
The Which? judges specifically commended our no-pressure promise, noting it as “a clear point of difference which is reflected consistently across the customer journey.”
We firmly believe that upgrading your home is a major financial decision that requires careful thought, not rushed coercion. Our sales team is completely salaried, not commission-based. This means they are working solely to find the right architectural solution for your home, rather than just chasing a signature for their paycheck.
We don’t do fake interest-free credit or sudden price drops if you “sign today”. Instead, we provide a full, transparent, written quotation for you to review entirely at your leisure.
Why the Which? Badge Matters to Us
We have proudly been a Which? Trusted Trader for over 17 years. The glazing and home improvement industry has historically suffered from a tarnished reputation, and we know that inviting a company into your home requires a tremendous amount of trust.
Because Which? conducts such a rigorous audit—meticulously checking our financial health, assessing our administrative procedures, and independently interviewing past customers—homeowners know that our endorsement is actively earned, never simply bought. It gives our customers the total confidence they need.
