About this site

We are Digital Signet, a small portfolio of single-purpose calculator and reference sites built by Oliver Wakefield-Smith. We are based in the UK. We are not solicitors. We are not regulated to give legal advice. What we are is meticulous about citing primary sources and keeping our rate tables current to the day a Statutory Instrument is laid.

The official GOV.UK calculator gives you the figure but does not explain the formula. ACAS explains the rules but does not run the calculation. Legal-information sites bury the answer below ads and contact-form CTAs. None of them carry the edge-case modellers (after-tax, enhanced top-up, historic year, full leaving package) in one place. We built this site to fill those gaps.

The weekly cap changes once a year, on 6 April. Within 72 hours of HM Treasury laying the uprating SI, we verify the figure against legislation.gov.uk, update the rate table in src/data/rates.ts, regenerate the worked examples on every page, and push a deploy. The verified date stamp on each page reflects the most recent rate check.

For all other rules (age bands, 20-year cap, £30k tax-free threshold, PENP formula) we re-check at least quarterly and on every Budget or Finance Act day.

None. There are no ads on this site, no affiliate links to legal-services providers, no lead-gen forms, and no email capture. The site exists as a portfolio trust-building project. If you want to support it, share the URL with someone going through redundancy. That is the only return we ask for.

Email oliver@digitalsignet.com with the URL of the page, the figure you think is wrong, and the source you want us to cite. We respond within 48 hours and publish corrections within a week. The verified-date stamp updates with every correction.

This site provides general information based on UK statute. It is not legal advice on your circumstances. For binding advice, contact ACAS on 0300 123 1100 or a regulated solicitor. We accept no liability for decisions taken in reliance on the calculator output. The £ figure is a guide; your employer's actual payment is determined by your contract, the relevant tax year, and any settlement agreement you sign.
