Frequently asked questions

Do I need to register to bid for government contracts?

You do not need to register anywhere to find and respond to most government tenders — they are published publicly. However, to express interest in opportunities, set up alerts, and submit bids, you typically need accounts on the relevant procurement portals. The Supplier Registration Service (SRS) is strongly recommended as it stores your information for reuse across multiple bids.

Is there a single government supplier register in the UK?

The Supplier Registration Service (SRS) at supplierregistration.cabinetoffice.gov.uk is the closest to a single register, introduced alongside the Procurement Act 2023. However, Scotland uses its own PCS-Tender system, and many individual buyers have their own supplier portals. You may need to register on multiple systems.

How long does government supplier registration take?

Registering on the main portals typically takes 1-2 hours in total. The Supplier Registration Service takes 30-60 minutes with your documents ready. Each portal takes 10-15 minutes. Have your Companies House number, insurance certificates, and key accreditations to hand before starting.

Do I need to be VAT registered to supply government?

No. VAT registration is not a prerequisite for government contracting. However, most above-threshold contracts go to businesses of sufficient scale that VAT registration (above £90,000 turnover) would typically apply. Some buyers specify minimum turnover requirements that effectively require VAT registration.

Can sole traders and freelancers bid for government contracts?

Yes. Sole traders and freelancers can bid for government contracts, particularly through frameworks like Digital Outcomes and Specialists. However, financial standing requirements (typically minimum turnover 2x the contract value) can be challenging for smaller operators. Frameworks with lower turnover requirements and below-threshold contracts are more accessible.

What documents do I need to register as a government supplier?

Commonly required documents include: Companies House registration number, last 2 years' accounts, public liability insurance certificate (minimum £2-5m), professional indemnity insurance certificate, employer's liability certificate (if you have employees), and any relevant accreditation certificates (ISO 9001, Cyber Essentials etc).

How do I register on Public Contracts Scotland?

Go to publiccontractsscotland.gov.uk and click Register. Create a supplier account with your company details and contact information. Once registered, you can search for opportunities, submit expressions of interest, and access tender documents. Registration is free.
