Become a MOD Supplier

Overview

The Ministry of Defence (MOD) spends approximately £29 billion a year with UK companies. Around 12,000 SMEs already work in the defence supply chain, and the government's Defence Industrial Strategy 2025 targets increasing SME spending by 50% to £7.5 billion a year by May 2028.

The MOD does not maintain preferred supplier lists. Any business that meets the quality, security, and compliance standards can bid for contracts.

Where to find MOD contracts

Register on all three portals — they list different types of opportunity:

• Defence Sourcing Portal (DSP) — the MOD's main e-sourcing platform. All advertised requirements over £10,000 are listed here. Registration is free. Set up notification alerts for your category codes
• Contracts Finder — government contracts over £12,000 (including VAT). Covers MOD and all other public sector buyers
• Find a Tender — high-value contracts above £139,688 (including VAT). Required for above-threshold procurements under the Procurement Act 2023

Also check the MOD Acquisition Pipeline for forward-looking procurement activity and framework agreements, so you can plan ahead.

Requirements you must meet

Cyber security

Cyber Essentials Plus is mandatory for most contracts involving IT systems or sensitive data. Certification costs £400 to £700 through an IASME-certified body and takes 6 to 8 weeks.

Quality standards

• AS9100 for aerospace quality management
• AQAP-2110 or AQAP-2210 for NATO quality assurance
• ISO 9001 as a minimum for non-aerospace contracts. Certification costs £3,000 to £10,000 depending on company size

Supply chain accreditation

Many prime contractors require JOSCAR (Joint Supply Chain Accreditation Register) membership before they will consider you as a subcontractor.

Security clearances

For classified contracts, your staff need clearance from UK Security Vetting (UKSV):

• SC (Security Check) for SECRET access — 6 to 18 weeks
• DV (Developed Vetting) for TOP SECRET access — 6 to 12 months

Your company must sponsor clearance applications. Plan well ahead as clearance processing times can be lengthy.

Export controls

If your contract involves controlled goods or technology, complete an F680 compliance declaration from GOV.UK.

Procurement Act 2023

The Procurement Act 2023 replaced the previous EU-derived procurement regime from 24 February 2025, including the Defence and Security Public Contracts Regulations 2011. Key changes for defence suppliers:

• Single unified framework — one set of rules covering all public procurement including defence
• Central digital platform — mandatory transparency notices at each stage of procurement for above-threshold contracts
• Wider scope — the definition of defence and security contracts now covers goods, services, or works relevant to operational capability, effectiveness, or safety of the armed forces
• Contract modification rules — Section 70 applies from 1 April 2026, governing how contracts can be changed after award
