ENS & Safety and Security Declaration Services
Entry summary declarations filed before the goods reach the frontier, on the mode deadline rather than the invoice deadline. We file for carriers, hauliers and forwarders who would rather not run this themselves.
What an ENS Is, and What It Is Not
An entry summary declaration is a pre-arrival risk filing. It is not a customs entry, it does not calculate anything you owe, and filing one does not clear your goods.
What It Contains
Consignor and consignee, the route and the means of transport, the number and type of packages, a description of the goods and a commodity code, plus the references that tie the filing to the shipment. It describes the consignment, not its value, and it is submitted before arrival rather than at the border.
What It Is For
Customs authorities use the data to run risk rules before the goods are anywhere near them. The point is to decide early which consignments merit attention, so that the ones that do not can keep moving. The assessment happens while the vehicle, vessel or aircraft is still in transit.
What It Is Not
It is not an import declaration, so duty and VAT still need an entry of their own. It is also not an exit filing. Goods leaving Great Britain need an exit summary declaration where one is required, which is a separate obligation with separate timings, and we handle both.
The Great Britain Side, Since 31 January 2025
The GB requirement on EU imports took four years and three postponements to arrive. It is here now, and a lot of the operational detail is still not widely known.
The Waiver Ended, the Filings Started
Goods imported into Great Britain from the European Union have needed a safety and security declaration since 31 January 2025, when the waiver that had run since January 2021 finally ended. The requirement was originally set for July 2022, moved to October 2024, then moved again. Anyone still working from the older dates is working from a rule that no longer exists.
The Reduced Dataset
HMRC introduced a reduced dataset for entry summary declarations into GB, and it applies to imports from the European Union and the rest of the world alike. It cuts the number of fields that have to be populated, which matters when a carrier is filing hundreds of movements a week. HMRC's own research found that plenty of traders did not know it was available.
The Carrier Carries the Obligation
This is the part that gets misread. The legal duty to make sure an entry summary declaration is lodged sits with the carrier, meaning the operator bringing the goods into the territory. It can be delegated to an agent or a third party by agreement, and we do that work every day, but delegating the filing does not move the accountability.
- Agree in writing who is filing before the traffic starts, not after a load is held.
- The carrier still needs to know the filing was accepted and to hold the reference.
- Where we file, we send the reference back to the carrier and to whoever booked the load.
Filing Ahead of the Crossing
Declarations go to the S&S GB service, and the window that matters is the one the movement actually allows. Deep sea traffic can be filed days out. A trailer booked on the next sailing out of Calais cannot, which is why the deadlines below are the numbers that govern day to day work.
Deadlines Follow the Mode, Not the Booking
The clock on an entry summary declaration is set by how the goods travel. These are the standard limits, which run along the same lines on both sides of the Channel.
Deep Sea Containers
Filed at least 24 hours before the container is loaded at the port of departure, so the assessment happens before the box is on the ship.
Short Sea and Bulk
Two hours before arrival on short sea routes, and four hours before arrival for bulk and break bulk cargo on longer voyages.
Air
Short haul flights by the actual time of departure, long haul at least four hours before arrival, with pre-loading data filed earlier again.
Rail and Road
Rail two hours before arrival, or one hour on journeys under two hours. Road, one hour before the vehicle arrives at the frontier.
Why the Short Straits Are Different
A Dover to Calais sailing is around ninety minutes and a Eurotunnel shuttle is thirty five. On accompanied roll on roll off traffic the pre-arrival window is shorter than the time it takes to chase a missing consignee address, so in practice the filing has to be right before the vehicle checks in. Specific timings apply to roll on roll off and Channel Tunnel movements, and we work to those on every load we file rather than to a generic one hour rule.
When an ENS Is Missing or Late
The consequences differ by direction and by mode, but none of them are administrative footnotes.
Inbound to Great Britain
The movement is non-compliant on arrival and the carrier is the party HMRC looks at. Depending on the goods and the route that can mean the vehicle is stopped, the load is held while the position is corrected, or a penalty follows later against the operator rather than the customer who booked the freight.
Outbound Into the EU
No accepted filing means no valid reference to present, and the response can come before the goods move at all rather than at the frontier. That side runs through ICS2, which has its own release history, its own dataset and its own way of telling a carrier not to load.
Late Rather Than Missing
A filing that lands after the deadline is not a near miss. The risk assessment it exists to feed has already been skipped, so a late declaration frequently gets the consignment looked at rather than waved through. Amending an accepted filing before arrival is a very different matter and is usually straightforward.
Built For Volume, Not For One Off Filings
Safety and security work is high frequency and low tolerance. A carrier running forty trailers a day needs filings that go in without a conversation about each one, and a reference back fast enough to be useful to a driver already on the way to the port.
So we take the booking data in the form you already produce it, file against the mode deadline, and tell you the moment something is short. Where we also raise the import declaration or the transit movement, the safety and security filing is built from the same set of documents, so the references match each other.
- Tell us who the carrier is. The obligation sits with them, so the filing has to be made on the right basis.
- Send the movement data. Route, packages, goods description, consignor and consignee.
- We file to the deadline. Reduced dataset where it applies, full dataset where it does not.
- Reference straight back. To you, and to the driver or the traffic desk if that is quicker.
- Amendments handled. Details change constantly on roll on roll off traffic, so we amend rather than refile.
Who We File For
Most of this work comes from operators and forwarders who need the filings done properly at volume without adding a night shift to do it.

ENS and Safety and Security FAQs
Is an ENS the same thing as a customs declaration?
No. They answer different questions. The entry summary declaration tells customs what is coming and lets them assess the risk before it arrives. The customs entry deals with classification, value, origin, duty and VAT. A shipment usually needs both, and one being accepted tells you nothing about the other.
Who is legally responsible for filing it, me or my carrier?
The carrier bringing the goods in. Responsibility can be delegated to a broker or another party by agreement, and that is normal practice, but the accountability stays with the carrier. If you are a shipper being told your haulier has it covered, get that in writing and make sure someone is actually holding the reference.
What is the reduced dataset and can I use it?
It is a shorter version of the entry summary declaration that HMRC introduced for imports into Great Britain, and it covers goods from the European Union and elsewhere. Fewer fields means faster filing and fewer places to get something wrong. Send us a sample of your movement data and we will tell you whether it fits.
How late can I send you the data for a Dover crossing?
Later than most people expect, but not at the barrier. Road movements work to a one hour pre-arrival window, and roll on roll off and tunnel traffic have their own specific timings. The practical rule is that we want the data before the vehicle books in, because that is the last point at which a missing field can be fixed without holding the load.
Do I need one for goods leaving Great Britain?
An entry summary declaration is an entry filing by definition, so no. What outbound goods may need is an exit summary declaration, and separately a valid entry filing on the other side before they can arrive in the European Union. We look at both directions of a route so nothing is assumed to be somebody else's job.
Can you file if you are not handling the rest of the customs work?
Yes. Plenty of carriers and forwarders use us only for safety and security filings while keeping their customs declarations elsewhere or in house. We work under your instructions and in your name where that is what the arrangement calls for.
