The one thing to remember

Find a Tender is now the Central Digital Platform. It is NOT the same website as the Supplier Registration Service. If you registered on Find a Tender before 24 February 2025, you need to register again.

2. Before you start: have these ready

Have ready

  • A work email address for each person who will sign in. One person per account.
  • Your Companies House number and registered address.
  • A decision on who will be the first person to set up the organisation. They can add and approve other users.
  • A mobile phone or an authentication app for security codes.
  • Your latest accounts, ready to upload.
  • Your certificates and assurances (for example Cyber Essentials, ISO, insurance).
  • Details of your directors and other people with significant control.

Tip: block out about 60 to 90 minutes. Do it in one sitting with the documents open.

3. Register on Find a Tender and the Central Digital Platform

  1. Step 1. Create your GOV.UK One Login

    • Go to the Find a Tender service (opens in a new tab) and select "Sign in with One Login".
    • Choose "Create your GOV.UK One Login". If you already have one, sign in.
    • Enter your work email address. Agree to the terms of use and privacy policy.
    • Enter the 6-digit code sent to your email. It can take a few minutes and may go to spam.
    • Choose a password.
    • Choose how to get security codes: text message or an authentication app. A text code runs out after 15 minutes.
  2. Step 2. Set up your account on the platform

    • Agree to the privacy policy.
    • Enter your first and last name.
    • You arrive on the "My account" page.
  3. Step 3. Register your organisation

    • On "My account", select "Register an organisation".
    • Select "Supplier". Do not choose Buyer.
    • Does your organisation have a Companies House number? Select Yes and enter it. The name and address then fill in for you.
    • Check your answers. Change anything that is wrong. Select "Save".
    • Select "View" to open your organisation. From here you can add other users and administrators.
  4. Step 4. Complete your supplier information

    This is the main job. From your organisation page, select "View" then "Complete Supplier Information". There are six sections:

    SectionBasic informationWhat to have readyCompany details, as registered.
    SectionConnected personsWhat to have readyDirectors, people with significant control, and anyone who controls the company.
    SectionQualificationsWhat to have readyRelevant professional qualifications.
    SectionTrade assurancesWhat to have readyCertificates such as Cyber Essentials, ISO standards and similar.
    SectionExclusionsWhat to have readyAnswers to the questions about situations that can exclude a supplier. Answer honestly. Take advice if unsure.
    SectionFinancial informationWhat to have readyYour latest accounts, ready to upload.
  5. Step 5. Share your information

    • Check everything is accurate. Select "Share my information".
    • Select "Create a share code". Read and agree to the declaration.
    • Enter the declarant's name, job title, work email and the organisation's postal address.
    • Check your answers. Select "Confirm and get share code".
    • Save the share code and download the supplier information file. Keep both somewhere easy to find.
    • When you bid, you give the buyer either the share code or the file. Some portals ask for the code. Some ask for the file.
  6. Step 6. Set up alerts and add your team

    • On Find a Tender, save a search using CPV codes or keywords, plus your region.
    • Add colleagues to your organisation so more than one person has access.
    • Check that a second person can use your security method when you are away.
    • Update your information and create a new share code whenever something changes: new accounts, a new certificate, a director leaving.

Done means

You can sign in. You can open a live notice. You can see your PPON (your unique organisation identifier) and a share code. You have at least one saved search.

4. Contracts Finder

  • Go to Contracts Finder (opens in a new tab) and create a free account. Verify your email. Alerts do not start until you do.
  • Search by CPV code, keyword, region and value. Save the search with a clear name.
  • Turn on email alerts for each saved search.
  • Check the first week. Too many results: narrow it. None: widen it.
  • Tip: save separate searches for each service you offer.
  • Contracts Finder and Find a Tender show different notices. Watch both.

Scotland, Wales and Northern Ireland have their own portals: Public Contracts Scotland, Sell2Wales and eTendersNI. Register on them if you want opportunities there.

5. Buyer portals

  • Each buyer uses its own portal. Common ones include Atamis, In-Tend and Delta.
  • Registering is free. It lets you see and download the documents. It does not enter you into the tender.
  • Do this when you find a tender you want. Create an account, express interest, then download everything.
  • Practice: pick one live tender and download the full pack, even if you do not plan to bid. Learn where the documents are.

6. Supplier Registration Service (SRS)

This is a different service from Find a Tender. Some central government buyers ask for it. Do not start here. Only register if a buyer asks.

7. G-Cloud and Digital Outcomes: where things stand

Checked 13 October 2026. These dates can change.

FrameworkG-Cloud 15PositionApplications closed on 30 January 2026 at 15:00. The award was published on 24 July 2026. It is designed to reopen to new suppliers about 18 and 36 months in. No date has been published.What to do nowYou cannot apply now. Watch Find a Tender for the reopening notice. Prepare your service description and certificates.
FrameworkDigital Outcomes and Specialists 7PositionThe Government Commercial Agency says it is due to reopen in summer 2027. Exact timelines are expected late 2026. No application route yet.What to do nowRegister your interest through the survey on the GCA page. Email info@gca.gov.uk with questions.

Important for planning

If your plan said "list on G-Cloud" in the first 90 days, move it. Use the time to get your certificates, service descriptions and case studies ready, and bid through Find a Tender and as a subcontractor in the meantime.

8. The ICO data protection fee

  • Organisations that use personal information must pay a data protection fee, unless exempt.
  • The tier one fee is £52. You get a £5 discount if you pay by direct debit.
  • It takes about 15 minutes and must be done in one go.
  • Have your organisation name and address, staff numbers and turnover, and your card details ready.
  • Start on the ICO data protection fee page (opens in a new tab).

This is a payment and registration, not an exam or a certificate. Check the amount on the page before you pay, because fees change.
