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.
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.

Blackwell Heating & Plumbing 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 19 years on the register also points to an established business rather than a brand-new one.
