Bring Customs Filing In-House

In a nutshell

Bringing customs filing in-house means your own team prepares and submits GB Customs Declaration Service (CDS) declarations directly to HMRC, instead of sending every consignment to an intermediary and paying a fee on each entry. Customs Declarations UK gives you guided CDS workflows, saved information and AI document processing (IDP) to build each entry from your invoices and packing lists, all on one account.

The gains are practical. You save time, because nobody has to brief an outside party, wait for a draft or chase a status. You save cost, because you pay a clear per-declaration price, or a subscription with volume discounts, instead of a margin on every entry. You have full control, because you see each declaration, its history and HMRC’s response the moment it happens.

We run onboarding and training and stay on hand once you are live, and you can start with your routine entries and widen from there at your own pace. CDS, safety and security, transit and GMR declarations all live on the same account.

Is it a good fit?

Is it a good fit?

In-house filing with CDUK suits any business that ships regularly and wants to own its declarations. If the foundations are already in place you can start straight away, and if they are not, our team helps you build them.

Start smaller, then scale

  • Documents arrive late: IDP and saved data speed up the catch-up
  • Procedures vary: guided wizards walk each entry through
  • Review time is tight: real-time validation catches errors early
  • Nobody owns customs yet: our training and audit trail help
  • Begin with one lane and add more as you grow
Your route to first filing

Four steps to filing for yourself.

Moving in-house is a short, guided process. Our team works through each step with you, so by the day you file for real you have already seen the whole journey in the platform. Accounts are activated instantly and there is no minimum volume, so you can start small.

  1. Step 1: Choose a manageable starting point

    Pick a trade lane or product range to begin with. List the declarations, ports and formalities involved, and bring the safety and security filings and transport references onto the same account so nothing sits outside your view. Your team learns on entries it already understands, and the saved data carries into the next lane.

  2. Step 2: Get the setup right

    We help you confirm your registrations, authorisations and duty and import VAT arrangements, then set up your trader profiles and saved parties. For inventory-linked ports we connect you through CSPs, and GVMS (RoRo) movements and export declarations need no badge. Registration and set-up are done once, then every filing builds on them.

  3. Step 3: Prepare and review

    Build each entry with guided CDS workflows, saved information and IDP, which turns your documents into a reviewable draft. You decide the classification, value, origin and procedure, and the platform guides and checks them. Templates and declaration cloning cut the keying on repeat shipments. Real-time validation catches mistakes before submission.

  4. Step 4: Submit and follow through

    Submit directly to HMRC and see customs responses as they arrive, with notifications and a full history on every declaration. Corrections happen on your timetable. Nobody has to ring round to find out what happened to an entry, and everything is stored against the declaration.

Start where it counts

Three ways to start.

Every route ends with your team filing in CDUK, and you choose the pace. Begin with your routine entries, bring your harder lanes across with our help, or move one lane at a time.

Routine entries in-house

  • GB CDS
  • IDP

Repeat shipments with reliable product data are the quickest place to begin. Your team prepares and submits them with guided workflows and saved information, and sees every customs response as it arrives. You see each response the moment it arrives, so corrections are made the same day, and the audit trail shows who did what on each entry.

  • Saved commodity and party data removes repeat keying
  • Start from invoices and packing lists with IDP
  • File imports and exports with GB CDS
Frequently Asked Questions

Questions before you switch.

Can we start with just some of our entries?

Yes. Begin with the routine lanes you know best, then bring the rest across as your team gains confidence. There is no minimum volume, so you pay only for what you file. Our team plans the rollout with you, and starting small costs nothing extra.

What do onboarding and training cover?

Our UK team trains your people on the platform: wizards, saved data, IDP, review and submission. Sessions are shaped around your own shipments and your own team. You make the classification, value, origin and procedure decisions, and the platform guides and checks them. Every declaration has a full audit trail, and support stays available after go-live.

Can we move everything on day one?

You can, though a defined first scope is often the easiest start, so data quality and staff readiness are easy to check. Accounts are activated instantly, and we agree the rollout around your operation. Your team keeps filing while it learns, with our support alongside.

Will we need a port badge?

No port badge is needed for GVMS movements or export declarations, and we connect inventory-linked ports and airports through the CSPs CNS, MCP/Destin8 and CCS-UK. Read our guide to submitting GB import declarations without a port badge to see how it works.

What does it cost to file in-house with CDUK?

You pay as you go with no monthly fee and no minimum volume, up to £25 per CDS declaration, or choose a subscription with volume discounts. Prices are published up front, so you can work out your own cost per entry before you register. IDP carries no per-document fee, and Goods Vehicle Movement Service (GVMS) GMR creation is free when the declaration is filed with us. See our pricing page.

How do we get started?

Read the getting started guide, then book a demo with your own shipment so we can walk through setup, review and submission. Your account is activated instantly once you register, and our team is on hand if you want a walkthrough before your first entry.
