The rules we check, and what each one rests on

In short

• Sixteen topics, from right to work to retention. Each one lists its sources below.
• Two rule sets: the Appendix D evidence pack rules, version 1.7.0, and the Certificate of Sponsorship checker rules, version 0.4.0. Both were ratified on 6 October 2026.
• The GOV.UK pages are checked every day. When one moves, a person reviews it.
• Every finding cites its paragraph, so you can read the source yourself.

The two rule sets

Ratified means the written rules and the wording that goes with them were read and signed off by a named person, and the exact files are pinned. Any later change to those files puts the product back to a draft banner until the new version is signed off.

Checked every day

A scheduled job asks GOV.UK about every page in the tables below once a day and records whether the page changed after the date we pinned. A page that has moved is put in front of a person, who reads the change and decides what the rules need. Nothing is rewritten automatically.

The sixteen topics

1. Right to work
2. Identity documents and names
3. Immigration status and permission
4. Entry, start date and the 28-day rule
5. Recruitment and genuine vacancy
6. Salary evidence (Appendix D §3)
7. Salary threshold and going rate
8. Salary per pay period: hourly rate, frequency, rolling windows
9. Skill level, SOC code and the role
10. Candidate qualifications and cohort cross-checks
11. English language
12. TB and health
13. CoS validity, allocation and the register
14. Reporting duties and absence
15. Record keeping: the worker file (Appendix D §5)
16. Retention, licence records and data protection

How SponsorFlow uses this

Each finding in a Certificate of Sponsorship check or an Appendix D pack shows the quote it read from your documents and the paragraph of the guidance or the Immigration Rules it was measured against. The solicitor accepts or overrides each finding, gives a reason and signs. A signed pack states when its rules were ratified. SponsorFlow never holds an SMS login, and it does not give immigration advice.

Questions people ask

SponsorFlow provides compliance software and record-keeping tools. It is not a law firm or an immigration adviser and does not give legal or immigration advice, which are regulated activities (Immigration and Asylum Act 1999, section 84). This page describes what the published Home Office guidance and the Immigration Rules say, with the paragraph for each point, so you can read the source yourself. Guidance versions and figures are those in force on the date shown; the Home Office changes them, so check the current version before you rely on any of it.
