Working with GRI in the UK gives recruitment agencies the potential to supply temporary staff to more than 120 client organisations across the public and private sectors.


GRI in the UK is part of Geometric Results Inc., the world's largest neutral vendor MSP. Entrusted with the management of £1billion worth of recruitment spend across more than 120 client organisations every year in the UK, we are a partner of choice and route to market for more than 3,750 agency suppliers.

Why join GRI?

Level playing field 

Every agency we work with signs a contract of supply at standard pay and charge rates. This means all our agencies are placed on a level playing field and therefore can compete on performance and quality of staff rather than price. And, because we’re a neutral vendor/independent recruitment outsourcer, you won’t play second fiddle to our own agency – because we don’t have one. Put simply, if the client has an agency vacancy you’ll see it first.

Increase in volume 

Many organisations work with lots of agencies in low volumes. By being on a smaller preferred agency panel, our agencies enjoy access to higher volumes of jobs in return for standardised rates. And, once you’re on our panel supplying to one client and exceeding quality standards, there are often other opportunities to supply to our other clients in the UK or across the world, through GRI’s global contracts. 

Shortened and regular payment terms

By standardising payment terms our agencies benefit from shorter and regular payment terms.

Streamlined administration

Our e-tips®  system which connects many of our clients and agencies together removes the need for paper-based timesheets and invoices, reducing the administration burden associated with temporary agency labour.

Visibility and control

e -tips® also provides a wealth of management information which helps our agencies to understand exactly where they are placing candidates and where further opportunity lies.

Legal compliance

Legislation is constantly evolving but our in-house legal team helps to ensure our agencies are aware of the correct process to follow. e-tips® also provides compliance visibility, for example flagging when candidates have reached their qualifying period for Agency Workers Regulations (AWR) or supporting on GDPR compliance.

Benefit from the latest advice, guidance and information on the topics that impact temporary staffing - from legislation updates to best practice ways of working - from GRI's market intelligence team with exclusive access to our Agency Support Hub.


There are two routes to join the GRI supply panel.

1) If your agency has never supplied to GRI before, the first step is to complete our Agency Expression of Interest (AEOI) form

As and when panel places come up which match your geographical and job expertise (as entered into the AEOI) we get in touch either by email or phone to see whether we can form a partnership and to take you through the steps of onboarding your agency onto the GRI panel. Please note, when completing the AEOI only add those areas you could cover immediately, rather than adding new areas you intend to cover in the future, as we can only partner with agencies that can provide immediate quality cover. If you have any queries regarding your application, contact

2) If you have previously supplied to GRI  and wish to do so again, but your supply contract  has lapsed, you would complete our renewal form, which will then be considered as panel opportunities arise. If you have any queries regarding your application, contact


Whether you are a previous partner or a new prospective supplier, we would recommend you follow GRI on LinkedIn, as we may also occasionally post ad-hoc requirements for new agencies, if we cannot secure a partner from either waiting list.


We follow a rigorous assessment process. This includes Companies House checks, proof of insurance documents and taking you through our contract and KPI standards. Once you are on our panel, as part of our service commitment to our clients, panel agencies will need to prepare to be audited on a regular and ongoing basis to ensure that the required standards are being upheld and that the necessary regulatory checks are being carried out, including compliance with the Modern Slavery Act.
