Public evidence profile
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.
Blue Line Build Ltd 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.

Very helpful and provided advice throughout the process of refurbishing two of our bathrooms. We are very happy with the results and our experience.
I bought a kitchen from Wren and found Konrad on Checkatrade. I invited three builders to quote, and he gave me by far the most confidence - he was knowledgeable, honest, and transparent with pricing. He installed the kitchen to a very high standard, working long hours without ever cutting corners. Everything was finished precisely and professionally. His pricing was fair compared to others, and he wasn’t pushy about upselling anything. We’re so pleased with the result and would highly recommend him to anyone needing a reliable, skilled builder.
Konrad did an amazing job replacing my kitchen and repairing damage from a leak. The work included a small interior remodel, new floors and the kitchen installation. He paid attention to detail, asked me all the right questions and when he came across a problem he’d always suggest a solution. I could not be happier with my new kitchen and would use him again anytime.
