Procuring your contracts from this DPS is easy.

We will manage the process and be the initial point of contact if you need any help or advice. The DPS is open until February 2029.

The DPS provides you with a compliant route to appoint contractors all experienced in delivering projects for the housing sector. It’s been split into 4 Lots covering the delivery of individual measures and whole house retrofit works. It’s been designed to sit alongside our Decarbonisation Partnerships Framework. 

Some aspects of a DPS are similar to a framework – but an important difference is that suppliers can join or leave at any time. This makes it easier to include local SME contractors, or new suppliers to bid for your tenders.

How to use the DPS

All call offs from the DPS have to be mini tenders. We will manage this process and be the initial point of contact if you need help or advice.

Step 1

We’ll talk to you about your upcoming project and ask you to complete a pre-project form. This helps us to tailor our services to your specific project and get you procurement ready.

Step 2

Any contractors which you already know can register to join the DPS at this stage. Once approved they can then be included in your tender.

Step 3

Once you’re happy to proceed we will issue an Invitation To Tender (ITT). This will go to all of the suppliers on the relevant Lot of the DPS. Suppliers can choose to opt-in or opt-out.

Step 4

Interested suppliers will then return the completed ITT by the deadline. We will compile the tender responses and send these to you for evaluation.

Step 5

You will evaluate the submissions and we can help you with your tender report. You can then write the award letters, or we can do this for you. The award letters will then be sent out to the tenderers.

Step 6

We can help you draft your contract if required. 

Who can access this DPS?

Any publicly funded body can use the DPS – access is not limited to SEC Members alone. Full details can be found here.

Is there a cost to access? 

There is no access fee to use our DPS. A levy % dependant on whether you are a guest or member is collected directly from the contractor once a call off contract is awarded. The levy operates on a cascade system – with the % charge decreasing in line with contract spend.
If you’d like to discuss this with us in more detail please let us know – we’re happy to help.

Can I ask my preferred suppliers to join the DPS?

Yes – if you have any small and/or local firms you like to use for certain repairs or maintenance works and are looking for a complaint route to award, you can point them to our DPS. This will make mini tenders including your preferred suppliers easier. We’ve produced some advice for suppliers looking to join the DPS here.
