SME Procurement Hub

London’s largest organisations want to help smaller and diverse-owned businesses to work with us.

Formed to help tackle London’s inequality and green recovery following the COVID-19 pandemic, the London Anchor Institutions’ Network (LAIN) is a partnership between the public sector, education, cultural, faith-based and private industry organisations.

Members of the network, including NHS London, Greater London Authority, Metropolitan Police Service, Transport for London and the University of London, have an ambition to purchase more goods and services from London’s smaller and diverse-owned businesses, either directly or through our vast supply chains.

We know that public procurement processes can be confusing or difficult to engage with – especially if this is new to your business. We’ve pulled together some essential tips and resources to help you to feel more confident in doing business with organisations like us.

Finding contract opportunities

You can find more information about our contract opportunities and how to do business with the London Anchors by visiting the websites below:

All public authority contracts are published on the government’s public tender portals, including:

Please note that you will need to register as a supplier in order to tender. New contracts are continually added, so do check back regularly. Tip: Use the ‘Advanced Search’ option to identify contracts particularly suitable for SMEs or VSCEs.

Reserved contracts

As part of our commitment to supporting London’s smaller and diverse-owned businesses, we are looking to reserve contracts under the relevant UK public sector threshold (typically, £213,477 inclusive of VAT for service contracts) specifically for London-based and or/micro, small and medium-sized businesses and/or those from the Voluntary, Community and Social Enterprise sector.*

This means that some lower-value contracts can be reserved for suppliers like yours in a specific geographic region (in this case London) following a competitive bidding process. From catering and cleaning, through to social media or picture-framing, you might be surprised at the range of reserved contracts on offer.

You can find these contracts as described above.

Tip: search for “Reserved Contract” within the opportunity title or description.


Micro business: <10 employees and turnover <£1.76m per year
Small business: <50 employees and turnover <£8.8m per year
Small and Medium Enterprise: <250 employees and turnover <£45m

VCSE: (voluntary, community and social enterprise) describes any organisation that works with social purpose and that generates revenue through trading and reinvests any surplus back into the business or the community it serves.

Support & Events

The London Anchor Institutions’ Network is hosting a market engagement event on Thursday 29 June 2023 for small businesses interested in doing business with us. The event will showcase a variety of live reserved contract opportunities as well as provide topical workshops and time for networking.
