How we check DIY information
Every source has a jurisdiction, scope and review date. We compare model numbers with manufacturer information and published recalls before naming a product, rather than relying on a broad marketplace search.

What a product must prove
Before a product earns a place in a Top 4, we match the model and package, find the corresponding UK product page, check published OPSS alerts and make sure each option serves a genuinely different buyer. If those checks are incomplete, we explain how to choose without naming that product as one of the four.
Exact model, identifier and batch screening against current UK product safety alerts, reports and recalls.
An absent search result is not a safety clearance; exact model and identifier matching is still required.
