Aggregation

Unlock the power of collective buying with Crown Commercial Service

With budgets and resources tighter than ever, public procurement is no easy task. That is why we are committed to helping public sector organisations save significantly through the power of collective buying. Our complimentary aggregation service combines the similar needs of customers from across the public sector, increasing our national buying power to achieve savings that would not be possible through individual buying.

Our team of experts will take care of the aggregated buying process for you, so that you can focus on other business priorities, or more complex procurements. We will make sure we get you the best possible deal, helping you achieve social and economic value.

  • what you need (a description of the product or service)
  • volumes
  • timescales

Potential opportunities

Can’t see an aggregation that meets your needs? Reach out and let us know.

We can consider any opportunity for aggregation, provided there is enough interest. We are currently exploring:

  • fibre roll out for schools
  • software asset management (SAM) services
  • Adobe software
  • IT hardware leasing
  • IT hardware longer term contract
  • funds disbursement
  • radio and CCTV
  • HSCN

We can also look into sector specific competitions. Fill in our online form stating your area(s) of interest in the comments box and we will get in touch to discuss your needs.

Not suitable for

Aggregations work best with common goods or services that will attract more than one customer and supplier. They are not suitable for

  • complex needs
  • services or needs unique to a single buyer
  • buyers with a specific or short deadline (it can take some time to get enough customers together to achieve the best savings)

Time to supply

We advertise open aggregation opportunities about 8 weeks before the tender is published.

Once the tender is published, it takes about 6 to 8 weeks for the procurement process to be awarded. After this, with support from the aggregation team, your orders can be submitted to the winning supplier. These timelines may vary depending on the size and complexity of the procurement.

For more specific timelines, take a look at our current aggregation opportunities.

Microsoft licensing

About the event

To support the CCS negotiated DTA21 Memorandum of Understanding (MoU), we run a programme of aggregated competitions to help you secure a value for money Microsoft Licence Solutions Partner. (LSP).

What can you buy?

The programme of procurements covers all enrolment dates and covers all Microsoft licensed products.  

Who can join

Each procurement is available to all public and third sector organisations who buy their licenses through an LSP (reseller).

Please note that all participating customers will receive the maximum discounts available to them from Microsoft through this competition. This is normally the discounts within DTA21 negotiated by CCS, however some customers may receive greater discounts (for example, health customers may be eligible for the N365 discounts).

Mobile voice and data services

About the event

For many public sector organisations, the routine purchase of mobile voice and data services can lead to varying contract end dates. This makes it difficult to switch suppliers to gain better value, as savings may be reduced due to early termination charges.

To support you with this challenge, we run regular national further competitions for mobile voice and data services under lot 2 of our Mobile Voice and Data Services (RM6261) agreement. This will help you achieve savings which will not be reduced by early termination of existing contracts.

What you can buy

Mobile voice and data services.

Who can join?

Available to all public and third sector organisations.

To decide if this particular aggregation is right for you, consider the following:

  • this aggregation is not suitable if you have an urgent need
  • are you confident that your requirement will be fulfilled through this competition? 
  • are you able to accept the network coverage provided by the suppliers listed under lot 2 of the agreement?
  • are you in a position to migrate at least 80% of your nominated connections to the winning bidder within 12 months of award of the aggregated procurement?

Get in touch with the team if you want to learn more about the scope of this aggregation

Why get involved?

Benefits of join this aggregation include:

  • phased migration across a 12 month period: the requirement is for 80% of nominated connections to transition to the winning bidder within the first year of the contract award, giving flexibility when existing contracts are yet to terminate and helping to avoid early termination charges
  • co-terminus contract term: all connections will cease on a common end date helping to prevent inconsistent contract end dates to simplify future procurement
  • ‘build your own’ tariff approach: the aggregated procurement allows for a base connection with no line rental charge, negating zero-use costs

Timetable

See our events page for precise dates for the next couple of competitions.

Joining the CCS aggregation for mobile voice and data has provided a 51% saving against the previous contract which under the current economic climate is essential. The aggregation attracted 16 buyers which increased the buying power, encouraging the suppliers to pass on savings because of the volume of the collective connections and data volume requirements.
