D2S recharging

Starting from April 2026 Defence Digital Foundry services, including Defence Developer Services (D2S), will begin recharging.

Recharging will affect all new and existing users who use the D2S Platform and/or D2S Tools at OFFICIAL. SECRET usage will not be charged until a future date, with advance notice given to users.

Users need to liaise with their Top Level Budget (TLB) finance teams to account for these costs.

Any future changes to charging models or license costs will be communicated in advance.

Principle

Recharging is a method which ensures teams who use the D2S service only pay for the infrastructure, resources and licenses that they use.

These charges are billed to the associated Unit Identity Number (UIN) and Local Project Code (LPC) for your project. This method of billing is effective, transparent and ensures your TLB are sent the correct amount.

Recharging helps teams budget and use resources economically, aligning with D2S’s more sustainable vision.

Models

D2S has two different pricing models which provide detail on how we charge for different products of the service, you will need to verify your identify to access the recharging models:

• Platform recharging model - provides detail on the recharging model for D2S Platform resources and benefits of the model.
• Tools recharging model - provides detail on the license recharging model for D2S Tools and benefits of the model.

Unique identifiers

We use unique identifiers used across Defence known as Unit Identity Numbers and Local Project Codes. They help systems track usage and manage licences. Without them, costs may be charged to the wrong Top Level Budget (TLB).

Your Top Level Budget will receive the bill for your usage directly, and liaise with you.

Unit Identity Number (UIN)

Your UIN starts with a letter, followed by 4 numbers, and ends with a letter. Each UIN has a name that describes the unit, sub-unit, or organisation.

Local Project Code (LPC)

Your LPC is a unique mix of letters and numbers. Each LPC has a name that describes the project. Some areas of Defence do not use LPCs. If this applies to you, you will be able to select ‘I do not have an LPC’.

If you do not know your TLB, UIN or LPC, ask your dedicated crown servant approver or your project finance team.
