What is Marketplace?

Marketplace brings together the UK’s largest community of construction industry suppliers and buyers to help them win more business. For suppliers, it offers them the chance to uncover both publicly available opportunities as well as unique opportunities from Constructionline buyers. And for buyers, it lets them target suppliers, using criteria not available on any other platform, to approach and gauge interest to build supply chains that meet the specific needs of their customers, projects and organisation.

What is the cost to gain access to Marketplace?

Marketplace is included with your standard Constructionline membership, saving you money over external services that aggregate public opportunities. However, if you decide Marketplace is something you don’t require our customer service team may be able to apply a discount to your account based on your turnover.

Can any department in my organisation use Marketplace?

There are no limits to the amount of users you can bring onto your account. Marketplace has been designed to allow your compliance, procurement and business development teams to work seamlessly together to help your business grow. 

Where does your data come from?

We take data feeds directly from the source to make sure they are as accurate and up-to-date as possible. For ‘Planning’ which includes over 400 UK planning authorities. For ‘Public’ we gather from OJEU/TED, Contract Finder and Find a Tender.

How up to date is the information about suppliers?

The information on Constructionline is continually being updated on the anniversary of its expiry date. Unlike self-certification services the database is maintained by our experienced registrations team and we write out to our suppliers as and when their information is due to expire. If a supplier fails to provide us with up to date information, after a series of reminders, they will be put onto consult status and this will be visible to you as you search the database.

How would you get my existing supplier list registered on Constructionline?

Once we have identified those suppliers that are not registered we will contact each organisation, explain you are now using Constructionline and suggest they should consider registering. Enclosed with the letters will be an application pack explaining to the supplier how Constructionline works, the benefits of being registered and the application form. With your agreement we would be happy to carry out follow up campaigns to help more suppliers register.

How much does it cost to register with Constructionline?

To discuss Buyer membership, please contact our Buyer services team who will be happy to you.

How many Buyers already use Constructionline?

There are currently over 10,000 buyers from 3,800 organisations across the UK using Constructionline, these include central government departments, local authorities, NHS trusts, housing associations, universities, colleges and main contractors.
