One system for every regime that applies to you

What Dulycore is

Dulycore is a compliance operating system for UK small and medium-sized companies, built and operated by Xpectrum Ltd. It answers one question: every compliance obligation your UK company owes — where are we with it, and what's next? The free compliance calendar maps deadlines from Companies House, HMRC, the ICO and every regime that applies, calculated from your company's own public record and reminded before they bite. Paid modules add tracking, checks and prepared filings for the regimes that need more — sponsor licence compliance first. Three commitments hold everywhere: data is held in the UK, every action is logged with a reversal recipe, and a human confirms every filing.

The starting point is free and stays free: paste your Companies House number into the deadline checker and your calendar builds itself from public data. Paid modules exist for the regimes where tracking alone is not enough — sponsor licence compliance is the first. Published pricing lives on the pricing page, in full, VAT stated.

How the guides are written

Every obligation guide on this site is written against the underlying legislation and official guidance, not against other summaries. Each page names its sources, carries a "last verified" line, and says plainly when a position is not yet resolved against a primary source — a gap stated is more useful than a number invented. Where the law gives a figure, the figure is quoted; where it does not, no figure appears.

Who is behind it

Dulycore is founded by Mo Farhat and built in the UK by Xpectrum Ltd, the company behind the Quematics and ComBeat brands.

Dulycore is built deliberately small and deliberately careful: one substrate, twelve modules, and a standing rule that no filing reaches a regulator without a named person's sign-off.
