Founder and data methodology lead

Peter Langdon

Peter founded TreatCompare and is responsible for the site's data methodology: source selection, price normalisation, audit trails, editorial scope and the corrections process.

Role on TreatCompare

Peter operates TreatCompare's data layer: scraper governance, pricing-data normalisation, source handling, outlier checks and publication rules. His authority on the site is data and methodology, not diagnosis, treatment suitability or clinical advice. Clinical review is shown separately only where a page has a named clinician and review date.

What this page is not

Peter does not review TreatCompare pages for clinical accuracy. Clinical review is handled separately by named medical reviewers where a page has been reviewed; see the medical reviewer directory. Healthcare suitability should always be discussed with an appropriate clinician; pricing should be verified against the provider before paying. For data corrections, use the public corrections route.
