How this score is made up
Missing evidence lowers the score because we can't check it. It doesn't mean it doesn't exist. Claiming a profile never changes the score. Evidence context, not a guarantee of workmanship.
Each card sums up one thing we can check from public sources. Open it for the full detail and the named source. This is evidence context, not a guarantee.

“Sash Window Wizards did a great job: the quality of the double glazed acoustic glass windows installed was very high, and my living room is now a lot warmer and sound proof as a result.” · Checkatrade, 17 Apr 2023
“Andy was exemplary in his neat and tidy workmanship” · Checkatrade, 17 Apr 2023
Sash Window Wizard is linked to a Companies House entry. This shows the business registration, not evidence of workmanship or service quality.
Why this helps you judge trust: this trader is linked to a registered company with named people who are legally accountable for it, on an official register anyone can check, a layer of accountability an unregistered trader doesn't offer. Around 7 years on the register also points to an established business rather than a brand-new one.
These reviews are published independently on the named public source below, not testimonials this business chose to show. We bring them together and link each one back to where it appeared, so you can open the source and read it yourself.
