ENS Declaration UK: What It Is and How to File (2026)

What is an ENS declaration in the UK? (ENS meaning and full form)

ENS stands for entry summary declaration. GOV.UK uses the terms entry summary declaration and safety and security declaration for the same thing. It is a short electronic declaration describing a consignment: who is sending it, who is receiving it, what it is, where it loaded, the route and when it will arrive. You lodge it with HMRC before the goods reach Great Britain.

Its purpose is risk assessment. HMRC says that UK customs risk-assess declarations to identify imports to control on arrival and, for deep-sea containerised cargo, shipments that should not be loaded at all. Great Britain requires these declarations as a signatory to the World Customs Organization SAFE Framework of Standards.

An ENS does not replace the import customs declaration. The ENS answers "what is arriving and is it safe to let it in"; the customs declaration, made in the Customs Declaration Service (CDS), deals with duty, VAT and the customs procedure. A consignment normally needs both. If you only need to understand the import side, see our guide to the MRN, the reference number returned when a declaration is accepted.

ENS declaration vs the EU's ENS

Great Britain and the EU run separate regimes. According to HMRC's RoRo guidance, the EU has had full ENS and EXS declaration requirements in place since 1 January 2021. A lorry crossing the Channel in either direction can therefore need an ENS on the side it is entering, filed in that side's system.

Do goods from the EU need an ENS to enter the UK?

Yes. For a long period there was a waiver for goods imported from the EU, and for territories that had no requirement before 1 January 2021. The waiver was extended in October 2024 and ended on 31 January 2025. HMRC's customs technical handbook now states that entry summary declarations for imports from the EU have applied since 31 January 2025 and that the requirement covers imports from both EU and non-EU countries.

Some movements are still exempt. The handbook lists, among others, qualifying Northern Ireland goods moving to Great Britain, electrical energy, pipeline entry, letters and printed material, travellers' personal luggage, postal consignments under Universal Postal Union rules, and goods declared orally or by conduct without a transport contract, which includes empty trailers, containers and packaging. The list is not exhaustive, and the exemptions are defined by type of goods or movement rather than by consignment value. Always check the handbook for your specific case.

Who files the ENS declaration? Carrier, haulier or customs agent

HMRC is explicit: the legal requirement to submit entry summary declarations within the time limits lies with the carrier. Who counts as the carrier depends on the movement:

A third party, for example a customs agent, can file on the carrier's behalf, but only with the carrier's knowledge and contractual agreement. The carrier remains liable for the filing, while the declarant is generally responsible for the accuracy of the data. Agree who files before the vehicle loads: HMRC warns that if both the carrier and a third party file for the same shipment, customs may use both declarations or accept only one of them. Our step-by-step guide for EU hauliers shows how this works for companies based outside the UK.

What you need to register for S&S GB

Declarations for goods entering Great Britain are made in the Safety and Security Great Britain (S&S GB) service. To register you need the business date of establishment, an email address, the business or trading name and address, a business UTR if you are registered for tax in the UK, and an EORI number starting with GB. If you do not have one you can apply during registration; see our guide to getting and using an EORI number.

S&S GB has no user interface. You submit an XML message using compatible software, or you employ a Community System Provider. This is why many EU carriers instruct a customs agent rather than buying and maintaining the software themselves. Easy Clearance is a customs agency registered for CDS with a UK EORI number, and we file ENS on behalf of carriers who instruct us. See the ENS and safety and security service for how that works.

ENS for the UK is not ICS2: two systems, two EORI numbers

Entry summary declarations for Great Britain are filed in the UK's S&S GB service. ICS2 (Import Control System 2) is the European Commission's system for goods brought into the EU customs territory, and GOV.UK also directs filers to it for goods entering Northern Ireland. A trailer that runs both ways therefore needs two separate security declarations in two different systems: S&S GB for the UK leg (using a GB EORI) and ICS2 for the return leg into the EU (using an EU EORI). Filing one does not satisfy the other, and a reference number from one system is not valid in the other.

ENS filing deadlines by mode of transport

HMRC sets minimum timing requirements in its customs technical handbook. You can submit up to 200 days in advance, and the declaration must be accepted before the goods arrive.

If a containerised booking is made less than 24 hours before loading, the carrier must use a later vessel to meet the 24-hour requirement.

Changes, delays and cancellations

• You can amend an ENS until the goods reach the border, and an amendment can be made after the time limit provided the original was filed on time. An amendment must contain all data from the original, with the changed items overwritten.
• You cannot change the details of the person lodging the declaration or their representative, and the customs office of first entry can only change to another office in the same destination, for example from one Great Britain office to another.
• For RoRo and road, a delay of more than two hours does not require an amendment if the vehicle keeps the declared route and carrier, leaves after the original sailing or scheduled departure, and departs the declared port no more than 12 hours after that time.
• You cannot cancel an ENS, only amend it. If the goods do not ship, no action is needed.

What information does an ENS contain?

The exact fields are set out in HMRC's spreadsheet "Entry summary declaration data elements for the S&S GB service", which marks each element as mandatory, conditional or optional. HMRC has updated it several times in 2025 and 2026 (including in 2026 to avoid rejected submissions), so always check the current version rather than relying on an old checklist. In outline, you need:

• Parties: the consignor and consignee, with EORI numbers where held, and the carrier.
• Goods: a description of the goods that actually identifies them (not "general cargo"), plus the quantities and weights the data elements call for.
• Transport and route: the means of transport, the routing country by country, and the expected date and time of arrival.
• Place of entry: the S&S GB location code for the port of entry. It has eight characters, "GB" followed by six digits. HMRC lists, for example, Dover as GB000040, Folkestone Eurotunnel Freight as GB000060, Felixstowe as GB000051 and Hull as GB000072.

Use the HMRC location code, not a UN/LOCODE-style abbreviation, when you complete the entry point. For a trailer, HMRC updated the data elements in February 2025 with new information about trailer registration, so confirm how it must be shown. Documents that usually support the data are the commercial invoice, the packing list, the CMR for road freight, the bill of lading for sea freight or the air waybill for air freight.

After you file: MRN, S&S GB and GMR

Once HMRC accepts the declaration, S&S GB returns a movement reference number (MRN). Pass it to whoever needs it at the border, normally the driver and the carrier.

The ENS and the GMR are different documents. The ENS is the safety and security declaration for the goods. The GMR is created in the Goods Vehicle Movement Service for a vehicle movement and groups the declaration references for the goods carried (see our guide to getting a GMR). HMRC's GMR guidance says that on EU to Great Britain movements including ENS MRNs in the GMR is optional, while for Great Britain to Northern Ireland movements the ENS MRNs are required, and including them means arrival and presentation notifications are submitted for you. The import MRN is added if the goods were declared into CDS. Our comparison ENS vs GMR: when each is required goes into this in more detail.

ENS references and import declarations are issued by different services, so the MRN from S&S GB is not the MRN of the import declaration made in CDS.

Penalties for a missing, late or inaccurate ENS

Penalties are set by the Customs Safety and Security (Penalty) Regulations 2019 (SI 2019/121). In the current Schedule:

These are maximums, not fixed charges. HMRC on review, or the tribunal on appeal, can set a penalty at any amount up to the maximum, including nil. No penalty applies where there is a reasonable excuse, but the regulations say that relying on another person to perform a task is not a reasonable excuse. That matters for hauliers who leave filing to a third party.

HMRC also says enforcement is evidence-based and proportionate and may involve border delays for checks. The practical cost of a missing or rejected ENS is therefore often the delay itself. If your ENS is rejected, our guide ENS rejected: what to do lists the usual causes and fixes.

ENS filing step by step

1. Agree who files. Confirm with the carrier, in writing, whether the carrier or an agent submits, so that only one declaration is made.
2. Check registration. The filer needs S&S GB access and a GB EORI number, or must instruct a provider that has them.
3. Collect the data. Parties, goods description, transport details, route and expected arrival, taken from the invoice, packing list and transport document.
4. Choose the entry point code. Use the S&S GB location code for the port or terminal of entry.
5. Submit before the deadline. Send the XML message through compatible software or a Community System Provider, ahead of the minimum timing for your mode of transport.
6. Record the MRN. Give it to the driver or carrier and, if you use GVMS, decide whether to add it to the GMR.
7. Amend if anything changes. Correct the declaration before the goods reach the border; you cannot cancel it.

Common reasons an ENS goes wrong

• Two filers for one load. The carrier and an agent both file, which can lead to either or both being used.
• Vague goods description. A generic description does not identify the goods for risk analysis.
• Wrong entry point. The location code must match the actual port of entry. Dover is GB000040, not a three-letter abbreviation.
• Outdated data elements. HMRC changes the data elements spreadsheet from time to time, so an old template may be rejected.
• Missing GB EORI. A non-UK carrier cannot register for S&S GB without one.
• Filing close to the deadline. A rejection then leaves no room to correct before arrival.

Exports to the EU: exit summary declaration

The ENS applies to goods coming into Great Britain. Goods leaving Great Britain need an exit summary declaration (EXS), and the EU may require an ENS on arrival. For RoRo, the haulier submits any EXS for accompanied freight and the ferry operator for unaccompanied freight. Our article on GVMS, GMR, ENS and EXS for exports to France explains the full sequence. For ordinary export procedure, see our export clearance service.

FAQ: ENS declaration UK

What is an ENS declaration?

An ENS declaration is an entry summary declaration, also known as a safety and security declaration. It is an electronic declaration of the goods, parties and route of a movement, lodged with HMRC before the goods arrive in Great Britain so that they can be risk-assessed. It is not a duty or VAT declaration.

What does ENS stand for?

ENS stands for entry summary declaration. GOV.UK also calls it a safety and security declaration. Exports from Great Britain have the matching exit summary declaration (EXS).

Who has to file the ENS declaration for the UK?

The carrier carries the legal duty: the haulage company for accompanied RoRo and for road through the Channel Tunnel, the ferry operator for unaccompanied RoRo, the shipping company for sea freight and the airline for air freight. A third party such as a customs agent can file on the carrier's behalf, but only with the carrier's knowledge and consent, and the carrier remains liable.

Do goods from the EU need an ENS to enter Great Britain?

Yes. HMRC's temporary waiver for goods imported from the EU ended on 31 January 2025, so entry summary declarations now apply to EU imports as well as to goods from the rest of the world, unless a specific exemption applies.

What is the deadline for an ENS declaration?

It depends on the mode of transport. HMRC's customs technical handbook sets two hours before arrival for accompanied and unaccompanied RoRo and for short sea journeys, one hour before arrival at the Eurotunnel terminal for road freight via the Channel Tunnel, and 24 hours before loading for containerised sea cargo. You can submit up to 200 days in advance.

How much does it cost to file an ENS declaration with Easy Clearance?

Our fees for ENS filing are published on the pricing page, so you can see them before you instruct us. Fees depend on the service and the number of declarations.

What happens if an ENS is missing, late or wrong?

HMRC can apply penalties under the Customs Safety and Security (Penalty) Regulations 2019, with a maximum of £1,000 for the carrier or the declarant for each relevant rule breached, and the movement can be delayed for checks. A penalty can be reduced or cancelled where there is a reasonable excuse, but relying on another person to do the task is not a reasonable excuse.

Is the ENS the same as a GMR?

No. The ENS is a safety and security declaration about the goods and is filed in S&S GB. The GMR (Goods Movement Reference) is created in the Goods Vehicle Movement Service for the vehicle movement. For EU to Great Britain movements, adding ENS references to a GMR is optional.
