Disclosure

Advertising

No advertising is served on this site at present. Space is reserved for it in the layout so that switching it on later cannot shift the page around, but nothing is being served into that space and no advertising cookies are set.

Affiliate arrangements

None. There is no affiliate relationship in place, no link on this site is a paid link, and nothing here earns a commission. The table below is generated from the site's own configuration, so it cannot describe a state the site is not in.

Why this page is generated

Because the alternative fails in a specific and expensive way. Hand-written disclosures drift: a site announces that its links are commissioned on pages where none are, or describes an affiliate arrangement it never signed up for, because the sentence was copied in during a redesign and nobody revisited it. Declaring a commercial interest you do not have is the wrong direction to be wrong in — it costs the reader's trust to buy nothing. Every sentence above is derived from a status field, and the build fails if any page contradicts it.

The check is deliberately blunt: if no programme is marked live, the suite scans every rendered page for the language of a commercial relationship and fails on a match. That is strict enough to catch this very paragraph, which is why it is worded the way it is.

What is not for sale

The figures. No advertiser or affiliate has any influence on the arithmetic, the sources or which thresholds are highlighted, and no page will ever be shaped to suit a commercial partner.

Why this page exists at all

A site about money that is free to read is being paid for by someone, and a reader is entitled to know who. The usual practice is a line of small print hedging that the site might be paid for some links, which is simultaneously vague and permanent — it covers every possible arrangement and describes none of them. This page instead states the arrangements that exist right now, and the funding note that appears on individual pages is generated from the same table, so the two cannot drift apart.

The current position

There is no advertising running, no affiliate relationship in place, no sponsored content, and no paid placement anywhere on this site. Nothing on any page earns anything if you click it. The links out go to GOV.UK, to HMRC and to the Scottish Government, because those are the sources for the figures.

That is not a statement of principle about never carrying advertising. It is a statement of fact about today, and the point of generating the per-page notice from the same table is that the day it stops being true, every page that is affected says so without anyone remembering to update it.

What would change, and what would not

If advertising is introduced, it will be marked as advertising, it will not be woven into the prose, and it will never sit where it could be mistaken for a calculated figure. If an affiliate relationship is ever entered into — a pension provider, a mortgage broker, an accountant — the page carrying the link will say what the relationship is, in the body of the page, next to the link.

What will not change is the arithmetic. The figures come from a tax engine that reads published statutory parameters, and there is no commercial input to it. There is no arrangement under which a number could be presented differently, and the shape of the code makes that checkable rather than merely promised: the parameters are in one data file, the engine is pure arithmetic over that file, and the method is written out at /method/.

What the site costs to run

Very little, which is the reason it can be honest about funding. It is a static site: pages are generated once and served as files, there is no application server, no database and no per-user compute. The running cost is a domain name and a content delivery network, and the calculators cost nothing because they run in your browser rather than on a machine that has to be paid for by the hour.

Editorial independence

No third party has reviewed, approved or influenced anything on this site. There is no client, no sponsor and no publisher. Where the site takes a view — that the marginal rate matters more than the take-home figure, that employer National Insurance belongs in any honest account of what a job costs — that view is argued from the arithmetic, and the arithmetic is shown so it can be disagreed with.

Corrections are not commercial

If a figure is wrong it is corrected and the correction is published at /changes/, whoever reports it and whatever it costs. There is no arrangement under which a correction would be delayed or omitted.

The one thing that would change the numbers, and why it cannot

The scenario a reader should worry about on a money site is not an advert. It is a figure quietly chosen to make a product look good — a pension relief number rounded generously, a comparison framed to favour whoever is paying. The structural answer here is that the figures are not chosen at all. They come from a pure function over a data file of statutory parameters, and there is no code path by which a commercial consideration could reach them.

That is checkable rather than promised. The parameters are in one file with a source URL and a date on every row. The engine is arithmetic over that file. The band boundaries are discovered and then asserted against the published statutory thresholds, so a parameter altered to flatter anything would fail the build rather than ship. Anyone who wants to verify a figure can read the working on the page it appears on.

How to check this page is current

The funding note that appears at the foot of individual pages is generated from the same table this page describes, so the two cannot disagree. Any change to the funding position is logged with a date at /changes/, in the same log as corrections to figures.

Reader-supported, in the literal sense of costing almost nothing

It is worth being explicit that this site is not a business waiting to be monetised. It costs a domain name and a CDN to run, the calculators cost nothing because they execute in your browser, and there is no team. That is the material fact behind the funding position: a site with no costs has no pressure to compromise, and a site that told you it was principled without telling you it was cheap would be leaving out the part that makes the claim credible.

If that ever changes, what you should expect to see

An honest disclosure is one you can audit rather than one that sounds sincere, so it is worth stating the specific things that would appear if the funding position changed. Advertising would be labelled as advertising and separated from the calculated figures, never placed where it could be mistaken for one. An affiliate link would carry the nature of the relationship in the body of the page beside the link, not in a footer. This page would list the arrangement by name, and the per-page funding note would change automatically because it is generated from the same table. And the change would be dated in the log at /changes/, alongside corrections to figures rather than in a separate place where it would be easier to miss.
