Civil penalty for illegal working — your 28-day response window.
If the Home Office serves your business with a civil penalty notice for employing someone without permission to work in the UK, you have 28 days to respond. The current maximum penalty is up to £60,000 per illegal worker. The Home Office decides whether to issue a penalty, reduce it, or withdraw it based on whether you can show a valid statutory excuse — i.e. that you carried out the prescribed right-to-work checks correctly before the worker started. If a penalty is issued, your options are to pay, to object within 28 days, or — if the objection fails — to appeal to the County Court. The first 48 hours after a notice arrives are the most important: this is when the response strategy is set.
Who this applies to: UK employers who have received a civil penalty notice, a referral notice, or an Information Request from the Home Office regarding a worker's right to work — and need to know what to do next, in what order, and on what timeline.

What the Home Office can issue you with.
The civil penalty regime for illegal working was significantly uplifted in early 2024. The current maximum penalty is set per illegal worker, not per business — so a single compliance visit that identifies multiple unchecked workers can produce a six-figure total within days. The penalty is in addition to any sponsor-licence enforcement action (downgrade, suspension, revocation) that may follow.
The 28-day clock starts the day the notice lands.
Always verify the current civil penalty timelines and figures against the notice itself and the Home Office Code of Practice on preventing illegal working. The numbers above reflect the published position at the time of last review.
The thing that decides whether a penalty stands.
The statutory excuse is the legal defence built into the illegal-working regime. If you can demonstrate that you carried out a prescribed right-to-work check on the worker before they started, in the correct format, and retained the evidence — and the document presented at the time appeared genuine and matched the worker — then the Home Office cannot impose a civil penalty even if the worker is later found to be in the UK unlawfully.
The order of operations when a notice arrives.
The single most useful thing you can do in the first 48 hours is preserve every record relevant to the named worker — and stop any communications that could undermine the response. Below is the structured first response we walk new clients through.
What we help with — and what we will refer out.
Civil penalty response is exactly the kind of regulated work where scope matters. Harveys Legal is regulated by the IAA at Level 1, which covers employer-side compliance advice, RTW process review, and objection preparation. Court representation is a higher-level matter.
