Entry summary declarations (ENS): UK and EU safety and security rules

Every consignment crossing into Great Britain or the EU now needs an advance safety and security filing. Here is who makes it, in which system, and what happens when it is missing.

This guide is also available in Polish.

What an entry summary declaration is

An entry summary declaration (ENS) is a safety and security filing made before goods arrive. It is not the import declaration that pays duty and VAT. It exists so customs can risk-assess a consignment in advance: who sent it, who receives it, what it is and how and where it is arriving. Both Great Britain and the EU require one, but they run separate systems, so a lorry going Dover to Calais and back may need two different ENS filings. If you want a plain-English explanation of the ENS declaration with a GB focus, that page is a useful companion to this one. For a quick definition, see the ENS entry in our glossary.

Goods entering Great Britain

Which system

According to HMRC, entry summary declarations for goods arriving in Great Britain are submitted through the Safety and Security GB service (S&S GB). Goods arriving in Northern Ireland follow a different route and are declared through the EU's Import Control System 2 (ICS2).

Who files

The legal responsibility sits with the carrier, meaning the operator of the active means of transport. HMRC guidance for hauliers says that for accompanied roll-on roll-off (RoRo) freight the haulier is the carrier and must make sure the ENS is submitted. For unaccompanied trailers, the ferry operator takes on that role. The carrier can file directly or use a customs agent, but using an agent does not move the responsibility.

EU goods are no longer exempt

For a period after Brexit, goods imported into Great Britain from the EU benefited from a temporary waiver from safety and security declarations. HMRC confirms that waiver ended on 31 January 2025. From that date EU-origin loads crossing into Great Britain need an ENS in the same way as goods from the rest of the world. Some waivers remain; HMRC mentions, for example, qualifying Northern Ireland goods moving into Great Britain.

Timing

HMRC says declarations can be submitted up to 200 days in advance and must be lodged within the legal time limits for the mode of transport. The deadlines differ between RoRo, the Channel Tunnel, air, deep sea and short sea. Check the current HMRC time limits for your route before relying on a figure quoted secondhand, including in this guide's companion pages.

What you will need

HMRC lists supporting documents such as the bill of lading or air waybill and the commercial invoice. The data itself covers:

• consignor and consignee details
• a description of the goods and their origin
• where and when the goods will arrive in Great Britain
• transport details for the crossing

The full data set is published by HMRC in downloadable spreadsheets, which your software provider or agent should work from.

After filing

Once accepted, HMRC issues a movement reference number and risk-assesses the consignment. For deep-sea containerised cargo, HMRC can issue a "do not load" message. For RoRo, the ENS reference can optionally be added to the goods movement reference (GMR) in the Goods Vehicle Movement Service; HMRC describes this as an optional extra step, not a replacement for the ENS.

Goods entering the EU: ICS2

On the EU side, the European Commission runs Import Control System 2 (ICS2). The Commission states that all economic operators bringing goods into, or transiting through, the EU must declare safety and security data to ICS2 through an ENS.

That matters for hauliers leaving Great Britain. Under ICS2 the filing can be a single ENS or split across multiple filings, depending on how responsibilities are agreed between the parties in the supply chain. HMRC's haulier guidance also notes that each EU member state applies its own procedures; for example, for France the ENS must be submitted before crossing the EU border, while in the Netherlands the data is provided when booking the crossing.

If you are moving goods under transit, the combined route through NCTS may be the practical option. Our guide to T1 transit from the UK to the EU explains how transit declarations work.

What happens without a valid ENS

The ENS is part of the risk assessment that happens before or at arrival, so gaps show up as delays at the border. The Commission warns that EU customs authorities may reject incomplete ENS filings or issue risk-mitigating referrals, which can slow processing when the goods arrive. On the GB side, HMRC can stop containerised deep-sea cargo from being loaded. For a lorry, a missing or rejected ENS typically means the vehicle cannot complete its crossing smoothly until the filing is sorted.

Practical checklist for UK–EU hauliers

• Agree in writing who files each ENS: the haulier, the ferry operator for unaccompanied trailers, or an agent acting for the carrier.
• Remember that one round trip can mean a GB ENS on the way in and an EU ENS on the way out.
• Collect invoice and consignee data before the load leaves, not at the port.
• Check the current legal time limits for your crossing.
• Keep the ENS separate in your mind from the import declaration; the ENS does not clear the goods.
