How we source ISO 27001 cost figures

Cost ranges on this site are based on public reference material across the relevant landscape. The publishers below are representative of the kind of source that informs our positioning, not an exhaustive extraction map per figure. A specific figure on a specific page is not necessarily anchored to a single named publisher.

Sources

  • UKAS-accredited certification body public materials. BSI, LRQA, NQA, Bureau Veritas, SGS, Alcumus ISOQAR, British Assessment Bureau, Citation ISO Certification and Tempo Audits.
  • GRC vendor public pricing. Publicly-published pricing pages and public G2 / TrustRadius contract-value reports for Vanta, Drata, Sprinto, Scytale, Secureframe, Comp AI.
  • Published practitioner survey data. UK ISO 27001 implementation survey data and write-ups published by ISMS.online, Hightable and ISO27001 community sources.
  • UK consultant public day-rate guidance. Publicly-published day-rate ranges from UK ISO 27001 specialist firms (Evalian, YourISO, Iseoblue, Kafico) and IT Jobs Watch UK ISO 27001 contractor day-rate panels.

What we deliberately do not publish

  • Specific certification-body fee tariffs. BSI, LRQA and others redact specific fee tariffs in writing. We publish the tier band, not the named-body specific quote.
  • Named-firm consultant rate cards. Day rates are presented as bands. Named-firm rate cards are confidential.
  • Side-by-side GRC feature grids. We publish positioning notes for major vendors but do not produce feature grids. Feature parity changes quarterly.

Update cadence

Site values update only when the underlying reality changes. Triggers:

  • ISO 27001 standard revision (2022 was the most recent major revision)
  • UKAS or related accreditation framework changes that affect assessment-day calculation
  • Major GRC platform pricing model change
  • Aggregate movement in UK consultant day rates greater than 10 percent over a 12-month sample

Cosmetic date bumps are not made.
