Potential suppliers

SSE is one of the UK's biggest companies with a supply chain value of over £2bn.

With safety, sustainability and responsibility at the heart of all we do, we're keen to establish strong relationships with our suppliers because we know how critical they are to our business.

We want to build and develop our supplier network and welcome any new engagement from suppliers who share our core values. Our simple step approach to working together incorporates the key engagement steps with our Suppliers - Registration, Tender Management & Contract Engagement.

The first step in building a relationship with us, irrespective of which part of SSE you wish to work for, is  to register using our Supplier Registration System which is hosted by Achilles Information Limited. For requirements that are subject to EU Procurement regulations, suppliers will be selected from Achilles UVDB in the United Kingdom or Achilles Supplyline in Republic of Ireland as this ensures your able to work with and support our teams safely and responsibly.

Our path to working together


Whilst our primary supplier selection process will utilise Achilles, for requirements that are subject to the EU procurement rules, Tender events will be published via OJEC/OJEU and suppliers will be able to participate directly and the procurement team leading the event will be able to advise and support you in joining the event via Emptoris.

For the second and third key steps  we have introduced the Emptoris system to manage & facilitate our core sourcing process. Emptoris is an online, cloud based solution which enables our procurement teams to create tender events, invite suppliers to participate and manage contract negotiation and award. We will be introducing Emptoris across SSE through the beginning of 2017 and we have provided further information on how to use and access the system in the dedicated section of this page.

Energy and Utility Skills Accord

SSE encourages its suppliers to become signatories of the Energy and Utility Skills Accord. The Skills Accord is designed to promote and lock-in sustained investment in the technical and operational skills the sector needs most via procurement practices. Signatories gain recognition for their strategic commitment to investing in employee skills development. See http://euskills.co.uk/skills-accord for more details.

More information on our procurement standards

Carbon emissions

SSE aim to prevent environmental damage and at all times comply with legislative and regulatory requirements. Furthermore, SSE will actively seek to develop positive environmental impacts as a responsible energy operator, develop and supplier.

We expect our suppliers and encourage their supply chain to measure, manage and reduce their carbon footprint. Furthermore, we expect our suppliers to report greenhouse gas emissions performance using internationally recognised greenhouse gas reporting frameworks (such as GHG Protocol and the UK Government’s environmental reporting guidelines) and standards in mainstream company reports and get data externally verified to standards (such as ISO14064 and ISAE2000) by credible accredited third parties.

Emptoris - Sourcing

Emptoris is being adopted across SSE for all tender events run by our Procurement teams. Our Procurement teams will be using the Online system provided by IBM to create and manage our Tender events from initial invitations through to finalising and awarding the contracts.

We would recommend visiting the Knowledge Centre links below to find more information on the system and its use.

Via these links you can access and watch video tutorials which guide you in using the system and participating in Tender events. Invitations to Tender events will be sent directly to all suppliers from the Emptoris system and will start the tender process with you and there are some key points to remember;

  • Accept or decline invitations to RFx(s) (Requests for quotations, proposals or information)
  • Respond to RFx questionnaires
  • Bid on individual items in an RFx
  • Make bespoke bids to suit your business approach (bundling, price breaks and discounting)
  • Have visibility (once invited to register) of all tenders, and contracts that you have or are participating in

More information on Emptoris is available in our short guide available here.

External Expenses (Non-SSE Resource) procedure

Subject to expense allowances within the contractual services, our External Expenses (Non-SSE Resource) procedure details the expenses which are reimbursable to Non-SSE resource when delivering a service on behalf of SSE or any SSE group company (SSE). The expenses set out in the procedure may only be claimed where there has been written agreement by SSE prior to the commencement of the contractual service. 

You can see the full External Expenses (Non-SSE Resource) procedure here.


SSE is committed to maximising the benefits and opportunities for local businesses and communities across the areas in which we operate and wish to promote local procurement where possible.

The Open4Business web portal allows us to provide visibility, regional and project specific business opportunities across the North of Scotland.

The portal creates a platform for us and our key contractors to post contract opportunities and increases visibility of our procurement process. Local suppliers can view and register for opportunities as a supplier and respond to notices free of charge.
