In a nutshell

A Safety & Security Declaration, formally the Entry Summary Declaration (ENS), is the pre-arrival notification that gives HMRC advance cargo information before goods reach Great Britain. It is lodged electronically to the Safety & Security GB (S&S GB) system, separately from the customs declaration, and since 31 January 2025 it applies in full to GB movements.

Customs Declarations UK turns that obligation into a repeatable workflow. File ENS declarations directly to HMRC across air, sea, road and rail, with guided wizards, real-time validation, AI document extraction and the option to generate an ENS from an existing declaration.

Frequently Asked Questions

ENS questions, answered.

What is an ENS / Safety & Security declaration?

An Entry Summary Declaration (ENS) is a pre-arrival Safety & Security notification that gives HMRC advance information about goods entering Great Britain. It is lodged electronically to the Safety & Security GB (S&S GB) system and is separate from the customs declaration. It carries no duties or taxes and is used to risk-assess cargo before arrival.

Who needs to file, and since when?

Responsibility sits with the carrier, though it can be fulfilled by another party in the supply chain. Mandatory Safety & Security declarations for goods moving to and from Great Britain took full effect on 31 January 2025, ending the earlier waivers that applied to EU trade.

Which transport modes are supported?

Air, sea, road and rail are all supported. The guided wizard adapts to each mode’s specific data fields and pre-arrival deadlines, so the right information is captured.

What data does an ENS require?

Since 31 January 2025 HMRC has reduced the GB ENS dataset to 20 mandatory fields (always required) and 8 conditional fields (required only in specific circumstances). The platform prompts for what your movement needs, with inline guidance for routing, carrier and commodity data.

Can I generate an ENS from another declaration?

Yes. You can generate an ENS directly from an existing import declaration in one click, so you don’t re-key data that already exists.

How much does it cost?

ENS filing is pay-as-you-go with no monthly fee, so you pay only for what you file. If you file regularly or at volume, we offer custom subscription plans with volume discounts. Get in touch and we’ll tailor pricing to your operation.
