Editorial Policy

How UKCalc maintains accuracy, independence and transparency across all content.

Last updated: 26 May 2026. Questions about this policy? Contact us.

Our Editorial Principles

UKCalc publishes financial calculators and guides to help UK residents understand their tax, salary and personal finances. Our editorial work is governed by the following principles:

Accuracy first

All figures are based on official published rates from HMRC, GOV.UK and other authoritative sources. We never publish estimates without verifying the underlying data.

Independence

Our editorial content is not influenced by advertisers. No calculator result or guide recommendation is paid for or sponsored. Advertising is clearly separate from content.

Transparency

We clearly state the assumptions our calculators make, explain what they cannot account for, and direct users to official sources for definitive answers.

Plain English

Financial information in the UK is often unnecessarily complex. Our standard is to explain every concept as clearly as possible without over-simplifying the underlying facts.

Who Produces UKCalc Content?

All calculators and guides on UKCalc are produced and reviewed by the UKCalc Editorial Team — a small team with working knowledge of the UK personal finance system, HMRC guidance, and Financial Conduct Authority regulation.

We are not chartered accountants, regulated financial advisers, or solicitors. Our content provides general financial information and accurate estimates — not personal financial advice. All content includes a clear disclaimer directing users to appropriate professionals for personal guidance.

Source Hierarchy

We use a clear hierarchy of sources when producing calculator rates and guide content:

Tier 1 — Primary (always used)

Official HMRC publications, GOV.UK guidance pages, Office for National Statistics (ONS) datasets, Bank of England publications. These are the definitive sources for all tax rates, thresholds and national statistics.

Tier 2 — Supporting (used for context)

Financial Conduct Authority (FCA) regulatory guidance, UK Finance industry statistics, ICAEW technical guidance, Resolution Foundation and Institute for Fiscal Studies (IFS) analysis. Used to provide context and verify our understanding of complex rules.

Tier 3 — Reference only (not used for rates)

Established financial publications (e.g., Which?, MoneySavingExpert) may be consulted as a cross-check but are never the primary source for any rate or calculation. We always trace figures to primary sources.

Update Process

Our calculators and guides are updated according to the following schedule:

  1. Annual update (April): At the start of each UK tax year (6 April), all calculators and guides are reviewed against the latest HMRC publications and updated to reflect new rates, thresholds and rules.
  2. Mid-year updates: When HMRC announces rate changes outside the normal Budget cycle (e.g., emergency measures), we update affected calculators within 2–5 working days of the official announcement.
  3. Budget updates: Following the UK Budget (typically in October/November), we update all relevant pages to reflect announced rates for the upcoming tax year, clearly marked as "from 6 April [year]."

Correction Policy

We take accuracy seriously. If you believe one of our calculators or guides contains an error:

  1. Use our contact form to report the issue, including the specific input values, the result you received, and the result you expected.
  2. We investigate all reported errors within 24 hours of receipt.
  3. If the error is confirmed, we correct the calculator or guide and update the "last updated" date.
  4. Significant corrections are noted in our Disclaimer and may be referenced in our site changelog.

Advertising & Commercial Relationships

UKCalc is funded by display advertising. Advertisements are served by third-party networks and are clearly distinguished from editorial content at all times. No advertiser influences our calculator results, guide recommendations, or editorial decisions.

We do not currently operate affiliate links, sponsored content, or paid placement. If this changes, all commercial relationships will be clearly disclosed.
