Covid-19 Supplier Update

Following the Government’s ease on lockdown restrictions, we’re moving into a recovery phase. This means that our trades and other teams are currently working towards resuming services where possible, ensuring the safety of our employees and residents at all times.  We’ll be contacting our suppliers over the next few weeks to discuss our recovery plans.

We’ll be continually assessing the situation and we’ll issue further updates as and when we can.

Please be assured that we’ve taken steps to make sure that all invoice payments will continue as normal, but in order to ensure that we’re receiving your invoices, we request that you email them in a PDF format (rather than post) to:  Please ensure you quote your PO number.

Working with suppliers

Last year we invested nearly £59m in repairing and maintaining homes and £175m on new properties. So it’s important we can access the best suppliers and achieve good value for money when we need to outsource.

  • Our dynamic purchasing system (DPS) for response and repairs is now up and running and is available through our Delta e-sourcing portal, potential suppliers can find more details here.
  • We’ve also set up an IT resource augmentation DPS through Delta, enabling us to access and on-board contract resources more quickly as we embark on an ambitious program of IT change. More detail is available here.
  • Additionally, if you’d like to be considered as a Sovereign supplierplease register on the Delta portal as this will notify you of any upcoming opportunities.
