ENS Declaration UK 2026 – What It Is and How to Submit It

What is the ENS Declaration UK?

ENS (Entry Summary Declaration) is an electronic safety and security declaration that must reach the UK customs authority (HMRC) before goods physically arrive in Great Britain. Its full name is sometimes Safety and Security Declaration (S&S Declaration) — in practice ENS and S&S Declaration refer to the same document.

The purpose of ENS is not to collect duty or VAT — it is a purely analytical and security-focused declaration. HMRC and UK Border Force use ENS data to:

• assess the risk of smuggling (drugs, weapons, prohibited goods),
• select consignments for physical or documentary inspection at the border,
• protect the supply chain from security threats (terrorism, sanctions),
• collect statistics on international trade.

An ENS Declaration UK does not replace the standard import declaration (C88/SAD, customs declaration). Both documents are independent — ENS is the "entry ticket to GB", and the import declaration is the "customs bill".

ENS vs EU ENS – what is the difference?

Before Brexit a single ICS (Import Control System) applied across the whole Union. After 1 January 2021 the United Kingdom built its own system — S&S GB (Safety & Security GB). On the EU side, ICS2 now applies. This means that the same lorry travelling from Dover to Calais submits two separate declarations: ENS to the EU (ICS2) and ENS to the UK (S&S GB).

Safety & Security Declaration after BTOM Phase 5

The history of ENS in the UK is turbulent. After Brexit the UK government repeatedly deferred the full implementation of the ENS obligation for goods from the EU. It was within the Border Target Operating Model (BTOM) that the final implementation path was determined.

Key dates:

• 1 January 2022 — ENS applies to goods from countries outside the EU,
• 31 October 2024 — launch of the new S&S GB system,
• 31 January 2025 — BTOM Phase 5: ENS fully enforceable also for EU imports into GB.

Until the end of January 2025, EU carriers were formally required to submit ENS, but HMRC applied a "soft landing" — penalties were nominal. Full enforcement has been in place since February 2025. For more on the inspection timetable, see the article on BTOM Phase 5 border controls UK 2026.

Who submits the ENS Declaration UK? Carrier vs importer

This is the question that causes the most confusion. Officially, under the UK Taxation (Cross-border Trade) Act 2018:

In practice, however, ENS may be submitted by:

1. The carrier — standard route, the carrier has its own software and GB EORI number.
2. A customs broker — acting under authorisation from the carrier (representation). This is the most common scenario for Polish transport companies that are not UK-resident.
3. The importer — if the carrier has no GB EORI and the importer agrees to take on the obligation (requires written consent from the carrier).
4. The EU exporter — in rare cases, where the parties agree in the contract (e.g. DDP Incoterms).

Requirement: GB EORI number

Regardless of who formally submits the ENS, that party must hold an EORI number registered in the UK (format: GB + 12 digits). A Polish transport company without a GB EORI cannot independently submit ENS — it must use a representative (customs broker) holding a GB EORI.

ENS submission deadline – depends on mode of transport

HMRC has set different time thresholds depending on the mode of transport. The deadline is counted from the moment of arrival at the first point of entry into GB territory (port, airport, tunnel).

What data does the ENS Declaration UK contain?

An ENS declaration in the S&S GB system requires approximately 25 data fields. The most important ones are:

Transaction party data

• Consignor (sender) — name, address, country, EORI number (if held).
• Consignee (recipient) — name, address, country, GB EORI number.
• Carrier — transport company name, EORI number.
• Notify party — party to be notified of goods arrival (e.g. customs broker, importer).

Transport data

• Mode of transport — tractor and trailer registration number (for truck), ship IMO, flight number, train number.
• Place of loading and place of unloading.
• Planned date and time of arrival at the first GB entry point.
• Port of departure and port of entry to the UK (UN/LOCODE code, e.g. GBDVR for Dover).
• Route — all transit countries.

Goods data

• HS code — minimum 6 digits (6-digit Harmonized System code) for each item.
• Goods description in English — specific, not generic ("general cargo" will be rejected).
• Gross mass in kilograms.
• Number and type of packages (e.g. 20 pallets, 300 cartons).
• Container numbers (for sea freight).
• UCR (Unique Consignment Reference) — if available.

Safety data

• Specific circumstance indicator — e.g. AEO, military, diplomatic.
• Transport payment code (e.g. cash, card, invoice — indicates financial risk level).

Missing or incorrect data causes the system to reject the declaration — it must be resubmitted. An incorrect HS code or an overly generic goods description are the most common causes of rejections.

The S&S GB system – how it works technically

S&S GB is the government IT system managed by HMRC, launched on 31 October 2024 to replace the old CHIEF S&S system. ENS declarations are submitted electronically in XML format via:

• direct API (Community System Provider — CSP),
• customs broker software (HMRC-certified Software House),
• dedicated port platforms (e.g. MCP Destin8 for Dover, CCS-UK for Felixstowe).

After accepting the declaration, the S&S GB system assigns a unique number — MRN (Movement Reference Number) in 18-character format. This number is then:

1. passed to the driver or carrier,
2. entered into the GMR (Goods Movement Reference),
3. presented at the port during document checks.

The ENS ↔ GMR relationship

Many carriers confuse ENS with GMR. These are two different documents:

• ENS (MRN) — safety declaration, relates to the goods.
• GMR — goods movement identifier, relates to the vehicle and "packages" all MRNs (import, ENS, T1 transit) into a single QR code that the driver shows at the border.

One vehicle = one GMR, but a GMR can contain multiple ENS MRNs (e.g. one lorry carrying 5 consignments for 5 recipients, each with its own MRN). Without a valid ENS you cannot create a complete GMR — and without a GMR the driver cannot board the ferry.

HMRC penalties for missing or delayed ENS

HMRC applies a graduated scale of penalties for ENS obligation violations. Legal basis: Customs (Safety and Security Procedures) (EU Exit) Regulations 2019 and BTOM Enforcement Guidelines 2025.

In addition to financial penalties, missing ENS results in vehicle detention by UK Border Force at the port terminal until the declaration is supplemented. The typical cost of a lorry and driver being held up is £80–£150 per hour, plus contractual penalties to the recipient. A single ENS error can cost a transport company several thousand pounds.

ENS procedure step by step – example of an import from Poland to the UK

Let's walk through the full path with a specific example: a Polish furniture manufacturer sends a pallet of oak dining tables to a business contact in Birmingham. Road transport, route Warsaw → Dover → Birmingham.

Step 1 — collecting data from the exporter

The customs broker or carrier collects from the Polish exporter:

• commercial invoice with goods value,
• packing list (number of pallets, cartons, weight),
• CMR (consignment note),
• exporter's EORI number,
• UK recipient contact details + their GB EORI.

Step 2 — goods classification (HS code)

For oak dining tables the HS code is 9403 60 (furniture of other wood). It must be assigned to each item. An error in the HS code = ENS rejection.

Step 3 — entering data into the S&S GB system

The customs broker logs into their software (e.g. Destin8, Descartes, ASM Sequoia) and fills in the ENS form. Data is transmitted in XML format to HMRC. This typically takes a few minutes for an experienced specialist.

Step 4 — receiving the MRN

The S&S GB system returns the MRN (e.g. 25GB04140000123456). This number goes to the carrier and driver.

Step 5 — creating the GMR

The carrier (or customs broker) creates a GMR in the GVMS (Goods Vehicle Movement Service) system. The GMR includes:

• MRN from ENS (safety & security),
• MRN from the import declaration (customs declaration),
• vehicle registration number.

The GMR generates a QR code — the driver shows it at the port.

Step 6 — arrival at the port and inspection

At Dover / Eurotunnel the system scans the GMR QR code. If ENS is green (green route) — the vehicle proceeds without inspection. If red (orange/red route) — Border Force directs it to an Inland Border Facility (e.g. Sevington, Ebbsfleet) for physical inspection.

Step 7 — document archiving

The exporter, customs broker and carrier must all keep ENS documentation for 6 years (in accordance with HMRC requirements). HMRC can request an audit at any time.

The entire process — from data collection to receiving the MRN — takes 15–30 minutes with a professional customs broker. See also the full UK customs clearance price guide with ENS service cost (from £25).

Common mistakes when submitting ENS

• Too generic goods description — "goods", "general cargo", "parts" will be rejected. The description must identify the specific product (e.g. "oak dining tables").
• Incorrect HS code — a 4-digit code is insufficient; a minimum of 6 digits is required.
• Missing GB EORI of the recipient — the most common problem with first shipments to a new client. Ask the recipient for their EORI before loading.
• Incorrect gross weight — discrepancies between the CMR and ENS trigger a physical inspection.
• Incorrect port code — Dover is GBDVR, not GBDOV. A mistake = rejection.
• Late submission — ENS submitted 30 minutes before a lorry's arrival is an automatic violation (minimum 1h for road).

FAQ – Frequently asked questions about ENS Declaration UK

Does the ENS Declaration UK also apply to exports from the UK to the EU?

No. ENS applies exclusively to bringing goods into GB territory. For outbound shipments from the UK to the EU you submit an EXS (Exit Summary Declaration) in the UK and an ENS on the EU side (in the ICS2 system).

Can I submit ENS myself, without a customs broker?

Technically yes — if you hold a GB EORI number and have access to the S&S GB system or certified software. In practice most Polish carriers use a customs broker, because the cost of software and training far outweighs the service fee (£25–£50 per ENS).

How much does submitting ENS through Easy Clearance cost?

The standard fee for an ENS Declaration UK at Easy Clearance is £25–£50 per declaration, depending on the number of goods items and urgency. For regular clients we offer a subscription with a lower rate. Find the full customs clearance price guide on our site.

What happens if a lorry arrives at the port without ENS?

UK Border Force will detain the vehicle at the port. The driver will not be allowed onto the ferry/tunnel. ENS will need to be submitted immediately (a customs broker needs approximately 30–60 minutes), a penalty of up to £2,500 paid, and downtime costs covered. Always submit ENS with a safe buffer of 2–3 hours.

Is ENS required for low-value shipments (below £135)?

Yes. The ENS obligation arises from security, not goods value. Even a consignment worth £50 must have ENS if it is carried by a commercial carrier. Exceptions apply only to postal shipments (B2C) up to £270 and passenger traffic.

Is the MRN from ENS the same as the MRN from the import declaration?

No. These are two different MRNs issued by two different systems: S&S GB (for ENS) and CDS (for the import declaration). Both are included in the shared GMR. The driver at the port shows a single QR code from the GMR, which contains both numbers.

How long is ENS valid after submission?

ENS is valid for the specific arrival — the date and time stated in the declaration. If transport is delayed by more than 24 hours or the port of entry changes, an amendment (correction) must be submitted in the S&S GB system. The amendment does not generate a new MRN, but must be approved before arrival.

What the current official guidance means in practice

S&S GB requirements and ENS procedures are regularly updated by HMRC. Always verify current requirements on gov.uk. The information in this article reflects the legal position as of April 2026.
