This page explains how PoundLogic produces its content — how we research, write, review, update and correct the calculators and guides on this site.

Our principles

  1. Accuracy first. Every figure, rate and threshold on this site is sourced from an authoritative primary source — usually gov.uk, HMRC, the FCA, the Bank of England or the ONS. Secondary sources are only used when no primary source exists.
  2. Show the working. Every calculator links to a methodology page that explains the formula, the assumptions and the data sources. If you can't reproduce our numbers, we haven't been transparent enough.
  3. Plain English. We don't use jargon to sound clever. If a term is technical, we define it the first time it appears on a page.
  4. No undisclosed promotion. Every affiliate link on this site is labelled. Affiliate relationships never affect calculator results or the order in which we mention products.
  5. Update when the rules change. UK personal finance rules change most often at the Budget, the Spring Statement, and the start of the tax year on 6 April. We review every rate-dependent calculator within two weeks of each of these events.

How we research

For any page involving a tax rate, threshold, allowance or regulatory figure, we use this hierarchy of sources:

  1. Primary government source — gov.uk, HMRC manuals, FCA handbook, Bank of England base rate, ONS published data.
  2. Official guidance — MoneyHelper (the government-backed service), Pension Wise, gov.uk income tax pages.
  3. Authoritative secondary sources — the Institute for Fiscal Studies (IFS), the Office for Budget Responsibility (OBR), the Resolution Foundation.

We do not use other personal finance blogs as sources for factual claims.

How we write

Every guide and calculator description is drafted by James Taylor. Where AI tools assist with drafting, the human author reviews, edits and fact-checks every claim and number before publication. We do not publish AI-generated content without human review.

How we review

Before publication, every page is checked for:

  • Factual accuracy against primary sources
  • Up-to-date rates and thresholds for the current tax year
  • Correct UK spelling and grammar
  • Working internal and external links
  • Affiliate disclosure where relevant

How we update

  • Tax year start (6 April) — every tax-related calculator and guide is reviewed and updated.
  • After each Budget and Spring Statement — any page affected by announced changes is updated within two weeks.
  • Quarterly — every calculator is reviewed for accuracy, broken links, and continued relevance.
  • Ad hoc — when a reader reports an error, we investigate within five working days.

How we handle corrections

We get things wrong sometimes. When we do, we fix it openly.

If you find an error on PoundLogic, please email [email protected] with the page URL, the specific claim or number you think is wrong, and the source you think we should be using.

We respond within five working days. If we agree, we:

  1. Correct the page.
  2. Add a note at the bottom of the page explaining what was changed and when.
  3. Log the correction on our corrections page.

Where the correction is material — i.e. it could have affected a reader's financial decision — we add a prominent note at the top of the page for 30 days.

Independence

PoundLogic is independently owned and operated. We do not accept paid placements, sponsored calculator results, or "review for review" deals. We do accept affiliate commissions from financial product providers, and these are always disclosed — see our affiliate disclosure.
