PROVIDER COMPARISON

A clearer view, side by side.

Choose up to three providers in the same service category. Compare what is published and what still needs to be established.

Compare equivalent services. Changing categories clears your selection. Unknown information is not treated as a negative score. No price ranking is shown without matching specifications and a current, eligible offer.
THE DETAILS, EXPLAINED

Build a more useful comparison.

Keep your shortlist focused on providers that offer the same type of service.

How many providers can I compare?

Choose up to three providers in the same service category. Use Compare on a card or add providers from the comparison page. Clear your selection to switch categories.

What information is compared?

The table shows published documentation, analytical methods, policies, commercial arrangements and unresolved checks. It does not calculate a quality score or certify a provider.

Are my selections saved?

Your shortlist is saved in this browser on this device. It is not sent to a PepSonar account or server. Use Clear to remove the selection.

How does PepSonar make money?

We may earn a commission from eligible purchases or referrals through disclosed affiliate links. A commercial relationship does not guarantee a favourable assessment. Suppliers without an affiliate arrangement use direct links.
