ECS Check 2026: When HR Must Use the Employer Checking Service

This is exactly the situation the Employer Checking Service exists for, and getting the timing wrong can cost you up to £45,000 per worker.

What is an ECS check?

An ECS check is a request to the Home Office to confirm whether a named person has the right to work in the UK when they cannot prove it through the usual methods. ECS stands for Employer Checking Service, run by UK Visas and Immigration.

It sits alongside the three standard right to work checks, not above them:

• Online share code check: for anyone with digital status or an eVisa
• Manual document check: List A or List B documents
• Digital identity check: via a certified provider, for British and Irish passport holders

The ECS is a fourth route. You only reach for it when none of the three standard checks are possible. Since Biometric Residence Permits stopped being valid on 31 December 2024, most workers now prove status with a share code, so genuine ECS cases are rarer than many HR teams assume.

When you must use the Employer Checking Service

You need an ECS check in a small set of defined situations. In some of these, using ECS is mandatory, not a choice.

Use the Employer Checking Service when your employee or candidate:

• Has an in-time application, appeal, or administrative review pending, and cannot show current status
• Holds a Certificate of Application under the EU Settlement Scheme that tells you to verify with the Home Office
• Holds an Application Registration Card, typically asylum seekers permitted to work in restricted roles
• Arrived in the UK before 1988 and has limited documentary evidence of status
• Genuinely cannot complete an online check because of a Home Office system or technical fault

In practice, the pending application scenario is the one HR teams meet most. Someone applied to extend their visa before it expired, their old status has lapsed on the system, but section 3C of the Immigration Act 1971 keeps their permission alive while the case is decided.

Quick reference: use ECS or not

When not to use ECS

Here is where employers get into trouble. ECS is not a catch-all for any awkward case. Every request is logged by the Home Office, and using it outside the defined scenarios can draw scrutiny you do not want.

Do not use ECS when:

• The person can generate a share code. Use the online check instead.
• You simply find manual documents inconvenient. That is not a valid reason to escalate.
• The visa has expired and no in-time application was made. A late application does not restore the right to work, and a notice issued in error will not protect you.
• You are checking a British or Irish citizen. They cannot get a share code, so check their passport.

Honestly, most teams complete the standard checks correctly and never need ECS at all. Treat it as a defined escalation step, not a default setting.

The ECS process, timing, and the 28-day grace period

Timing is where compliance is won or lost. You do not need a share code from the individual for an ECS request. You submit their details directly to the Home Office online.

Key timings to plan around:

• Wait 14 days after the person submits their application or appeal before requesting ECS. The Home Office needs time to register it.
• Expect a response within 5 working days.
• A Positive Verification Notice gives you a statutory excuse for 6 months.
• Existing employees keep a statutory excuse for 28 days after their visa expires, giving you a window to obtain a notice. This grace period does not apply to new hires.

The reality is that these windows overlap awkwardly. If you wait the full 14 days and the response takes 5 working days, you are already close to the edge of the 28-day grace period. Start early, and do not treat the grace period as spare time.

What Positive and Negative Verification Notices mean for you

PVN versus NVN: outcome and your next step

A PVN is time-limited, so put the expiry date into your tracking system the day it arrives. If the visa is granted within those six months, switch to a standard online share code check. If it is not, you need a fresh ECS check for the next six months.

Where ECS fits in your wider compliance duties

An ECS check is one piece of a larger duty. If you hold a UK sponsor licence, right to work failures feed directly into licence risk, and the Home Office can suspend or revoke over exactly this kind of gap. Reporting and check obligations also run through your Sponsor Management System duties, so a missed follow-up rarely stays contained.

You must keep evidence of every check, including ECS requests and verification notices, for the length of employment and two years after it ends. If you are unsure where your gaps are, a sponsor licence compliance assessment is a fast way to surface them before an audit does.

Get the sequence right before the offer goes out

Before your next offer letter reaches someone with a pending application, ask one question. Can they prove their right to work today, or do you need a Positive Verification Notice first? Getting that sequence right is the difference between a compliant hire and a £45,000 exposure per worker.
