Completing a SoECAT

Guidance for the completion of the SoECAT by the applicant is present in the online tool to assist at each page and stage of the application process.

There is also an Online SoECAT Guidance Module which includes video tutorials and linked resources (an NIHR Learn account is required to access and enrol onto the module) and some helpful user role infographics:

In order to create a SoECAT, you will need to create an account in the NIHR Central Portfolio Management System (CPMS) and follow the "Apply for a service for a new study" pathway. If any assistance is required in creating the account, please refer to our user guide. Once your account has been created and is active, you can proceed.

Where can I get more advice or support?

AcoRD Specialists at NIHR Local Clinical Research Networks (LCRNs) are available to support researchers, their teams and Sponsors in completing and authorising the completed SoECAT. Further information about AcoRD attribution support can be found on our What is AcoRD? page. To get in touch with an AcoRD specialist, contact the Lead LCRN for the study (usually the LCRN where the lead investigator/lead site is based).

The purpose of SoECAT

The Schedule of Events Cost Attribution Tool (SoECAT) is a tool for use with non-commercial research studies in the four UK nations. Its primary purpose is to ensure that site-level costs (*1) are appropriately attributed according to AcoRD (*2) principles at the time of application for research funding and hence to ensure that site-level Research Costs are met via that funding. It also has several other roles and functions:

  • SoECAT functions as a cost attribution template but is not intended as a study costing tool;
  • If completed at the research funding application stage, it should also form part of the IRAS application document set where the research is to take place in or through the NHS or Health and Social Care (HSC);
  • If submitted in IRAS, as above, it should form part of the UK Local Information Pack, that the sponsor or their authorised delegate shares with participating NHS/HSC organisations to support the arranging of local capacity and capability (England, Northern Ireland and/or Wales) or the issuing of NHS Management Permission (Scotland);
  • It provides the Excess Treatment Cost (ETC) per participant value, which in some UK nations informs ETC processes as per the nation-specific ETC processes section.

In forming part of the submission package for research funding the SoECAT introduces greater consistency and streamlining across the funding, planning and site set-up stages of a project.


(*1) By ‘site-level’ we refer to activities associated with the delivery of the research at site, i.e. excluding activities relating to study design and/or management, which we refer to as ‘sponsor-level’ and are outside of the scope of SoECAT
(*2) Attributing the costs of health and social care Research and Development guidance provides a framework for the NHS and its partners to identify, recover and attribute the costs of health and social care R&D (AcoRD), in a transparent, and consistent way. It makes clear the distinction between the 3 costs: research costs, NHS support costs and treatment costs and describes how these costs should be met.

SoECAT at research funding application stage

SoECAT is a cost attribution template designed to support correct cost attribution at application for research cost funding, to ensure that full site-level research costs are recovered. There are activities in addition to the site level activities that in many cases would also need to be included in the application for research cost funding (e.g. centrally incurred costs associated with management, monitoring etc.). SoECAT will not normally reflect all activities that are included within an application for research cost funding.

As SoECAT is based on a schedule of events and hence a participant pathway, it does not reflect the usual annual expenditure format of research cost funding applications. It also assumes that every participant will complete their allotted pathway.

The values generated by SoECAT use the baseline costing methodology from the NIHR CRN interactive Costing Tool (iCT) i.e. values before any commercialisation is added. These are average values that have been generated from data submitted by NHS providers and are reviewed on an ongoing basis. As with the iCT, it is not expected that a single template value will reflect the exact costs at each NHS commissioned provider/site.

It would be unusual for the summary figures generated by SoECAT to closely reflect those in the research cost funding application or in the final grant or award. For these and other reasons, SoECAT should not be used as a costing tool; other methods should be used to calculate the costs to be included in applications for research cost funding.

The SoECAT generates values using a consistent methodology that enables funders to make cost comparisons between similar studies. The SoECAT generates three values (as defined by AcoRD):

  • The Excess Treatment Cost (ETC) value, which is an indication of the potential overall ETC value of the study. The nation-specific ETC processes section sets how each of the four UK nations use this information.
  • The NHS support cost value, which is an indication of the potential overall NHS support costs (or their equivalent in a social care setting) that the study might need. This value is used to help funders determine the overall value for money of the study and may be used to help inform timing and provision of resources to undertake these support activities. The values generated do not represent the cost value of the NHS support that will be provided to the study in any UK nation.
  • The site-level research cost value, which is unlikely to be the total research cost of the study. This value provides an indication of site-level research costs, which are one element of the total research costs required to deliver the study. Funder application forms are designed to include all the research costs of the study and activities included in the SoECAT should help inform completion of the funder’s application form (but do not have to be the same, if applicants deem their costs to be different).

SoECATs must be authorised by an AcoRD Specialist prior to submission for Research Cost funding. The SoECAT thereby helps to ensure that Research Cost funding decisions do not need to be revisited because of activity omissions or incorrect attribution. To get in touch with an AcoRD Specialist, contact the lead NIHR LCRN for the study (usually the LCRN where the lead investigator/lead site is based). Please allow a minimum of 10 working days for authorisation of a SoECAT by an AcoRD Specialist. For studies led by Scotland, Wales or Northern Ireland please see the Nation Specific ETC Processes section.

When is a SoECAT required?

A SoECAT is required by NIHR and NIHR Non-commercial Partner research funders where the call relates to studies that may involve participants under an NHS or Health and Social Care duty of care. Applicants should follow the instructions of each funder, for that funding call:

  • If your study is funded by an NIHR infrastructure award where the NHS Support Costs are covered but the ETCs are not, you may need to complete a SoECAT to access the ETC process for England.

A single SoECAT should be completed for the Research Cost funding application for any non-commercial study intended for the NIHR CRN Portfolio, even where the funder is not NIHR or an NIHR Non-commercial Partner (i.e. where an application for CRN support and inclusion on the NIHR CRN Portfolio will be made). If you feel that your study should have multiple SoECATs (maybe due to multiple standards of routine care) then please contact your local AcoRD Specialist in the first instance to check that this is appropriate.

A SoECAT should be completed for the research cost funding application for any non-commercial study eligible for NHS support cost (or their equivalent in a social care setting) or ETC support in Northern Ireland, Scotland or Wales, even where the funder is not NIHR or an NIHR non-commercial partner and even where there are no sites in England.

Where a research cost funding application has an outline and second stage, the SoECAT should be submitted at the second final stage.

If in any doubt as to the requirement for a SoECAT at research cost funding application stage please consult the guidance provided by the research funder, contact the funder to discuss and/or contact your local AcoRD specialist. In many cases, the guidance for the application will be explicit, e.g. for NIHR and NIHR non-commercial partner funders. In other cases, the funder itself may not require the SoECAT but your local AcoRD specialist will be able to advise as to whether one should be submitted anyway, e.g. where NHS support costs (or their equivalent in a social care setting) or ETCs have been identified.

Some funding calls may attract both applications for studies that require SoECAT completion and applications for studies where SoECAT completion is unnecessary. In these circumstances, the SoECAT should be completed and submitted where the initial questions in the tool determine this is a requirement. Some NHS funders may determine that applications for a specific call will not require a SoECAT because none of them will require ETC or NHS support cost funding (e.g. funding calls for research not involving human participants). These funders will make this clear in the call guidance.

SoECATs should also be completed for applications for research awards that fund a programme of activity such as NIHR programme grants for applied research. Completion should be based on information available at the time of the application. Due to the nature of programme grant awards, study-specific SoECATs may be required once research studies being undertaken as part of the programme grant award have been defined – i.e. at the point of IRAS application.

Studies that are amended as a result of research funding panel decisions will need their SoECAT updated accordingly, including AcoRD specialist sign off.

All SoECATs, whether submitted for research cost funding or in IRAS, need to first be authorised by a designated AcoRD specialist from the lead nation. For cross-border studies, a SoECAT will only need to be authorised once and will be accepted where relevant in each UK nation involved in the study.

SoECAT is not used for commercial contract research studies. There is an iCT for commercial studies.

SoECAT at IRAS application stage

If a SoECAT has been submitted for the Research Cost funding application, it should also form part of the IRAS Form application.

Applicants who have not submitted a SoECAT in application for their Research Funding may continue to submit an IRAS Schedule of Events in their IRAS submission. Applicants for studies intended for inclusion in one of the UK research network portfolios are however encouraged to discuss this in advance with their local AcoRD Specialist. The AcoRD Specialist will be able to advise whether completion of a SoECAT will be required to access funding for ETCs.

One SoECAT HRA export file (downloaded ‘in system’ from the dashboard) should be submitted per outline organisation information document.

The activities in each SoECAT HRA export file should indicate the activities to be undertaken by the organisation with which that organisation information document and SoECAT HRA export file are to be shared (e.g. activities related to recruitment and treatment should be deleted from the SoECAT HRA export file intended for the organisations only undertaking follow-up). Activities not relevant to certain sites should be deleted from a SoECAT HRA export file without re-authorisation of that SoECAT by an AcoRD specialist. Activities should not be added, nor should attribution be modified, subsequent to authorisation by an AcoRD specialist. If such modification is required, the SoECAT should be re-authorised prior to IRAS submission.

SoECAT as part of the UK local information pack

Where a SoECAT HRA export file has been submitted as part of the IRAS application this will also form part of the UK local information pack to be shared with participating NHS/HSC organisations.

The UK local information pack should include the SoECAT HRA export file relevant to the organisation with which it is shared (e.g. organisations only undertaking follow up should be provided with the SoECAT HRA export file that includes only follow up activities).


If an IRAS application consisted of only one outline organisation information document and SoECAT HRA export file (as would be the case where all participating NHS organisations were expected to be undertaking the same activity) but the sponsor now intends to open organisations undertaking a subset of the overall site-level activities, (e.g. sites are being added that will undertake only follow-up activities) an appropriately modified SoECAT HRA export file should be provided to the national coordinating function of the lead UK nation as per guidance on non-substantial amendments. Similarly, if the original submission reflected more than one site type but additional site types are being added, additional SoECAT HRA export files should be submitted in accordance with the amendment process to reflect the new site type/s. Unless activities are added, or attributions modified, additional AcoRD specialist authorisation is not required.

Up to two amendments can be made to a study without submitting a revised SoECAT HRA export file , as long as the changes have no impact on ETCs, but upon a third amendment, excluding amendments to add sites/PICs, a revised and re-authorised SoECAT HRA export file should be submitted to ensure that the SoECAT HRA export file maintains alignment with the study. If the sponsor intends to amend the study in such a way that the ETC activities described in the SoECAT HRA export file submitted in IRAS are changed, a revised and re-authorised SoECAT/s should be submitted with the amendment.

Nation Specific ETC Processes

Although use of the SoECAT in application for Research Cost funding, as well as inclusion in both the IRAS application and the UK Local Information Pack, are common to all four UK nations, there are a number of nation specific differences relevant to SoECAT and these are set out below:


For non-commercial studies on the NIHR CRN Portfolio, the ETC figure generated by the SoECAT is used for the NHS E/I and NIHR CRN processes for recognising and recompensing ETCs.

  • For studies where Integrated Care Boards are the primary responsible commissioners for funding ETCs, the ETC figure used to recompense providers is the one generated by the SoECAT.
  • For studies where specialised commissioning is the primary responsible commissioner, an additional financial assurance process is required for funded applications to determine the net ETC funding that providers will require, to ensure there is no duplication of payments for activity likely to already be chargeable under existing NHS contracts. Specialised commissioning will provide additional support to the applicant where needed to complete the assurance process.
  • For studies involving services commissioned by other NHS E/I commissioners and for public health studies commissioned by local authorities, where there is an equivalent excess intervention cost the ETC value will also be used to inform the final agreed value. For guidance on managing ETCs for research into public health interventions commissioned by non-NHS organisations in England, read the following document: Researcher guidance for public health ETCs. 

Northern Ireland

The ETC value may be used in mechanisms for recompensing ETCs in Northern Ireland. Visit the HSC R&D Division - Northern Ireland website for more information about the process for studies taking place in Northern Ireland.


The ETC value may be used in mechanisms for recompensing ETCs in Scotland. Visit the NHS Research Scotland website for details on the Scottish process.


The ETC value can be used in Wales, exactly as generated or amended using the Welsh ETC costing template if more appropriate. Visit the Health and Care Research Wales website for more details on the Welsh process.

Functionality updates

In response to feedback from users, a number of changes have been made in the online SoECAT:

  1. The linked CPMS ID has been added to each page of the SoECAT to allow users to easily identify the study they are working on and navigate to the study record.
  2. The ability for a study representative to name each SoECAT has been introduced to allow users to easily identify their SoECAT and distinguish between multiple SoECATs associated with a study in those instances where multiple SoECATs are required due to vastly differing routine care pathways.
  3. The contact details for all study representatives associated with a study have been added to the AcoRD specialist authorisation page to allow easy communication throughout the review. 
  4. The ability for a study representative to copy an existing SoECAT for a study, including:
    a. Creating a portfolio SoECAT from an existing portfolio SoECAT
    b. Creating a portfolio SoECAT from an existing non-portfolio SoECAT
    c. Creating a non-portfolio SoECAT from an existing portfolio SoECAT
    d. Creating a non-portfolio SoECAT from an existing non-portfolio SoECAT
  5. The initial question flow has been modified to improve and shorten the user journey to determine which type of SoECAT is required for study representatives.
  6. Warning messages have been updated to better guide users.
  7. Scroll bars, frozen headers, increased field sizes and maximum character counts have been introduced to improve usability for all roles.
  8. The ability for users to hide the guidance text at the top of each page within the SoECAT to allow more activities to be displayed on the screen.
  9. The ability for users to choose 'Unknown' when selecting from the department list for an activity.
  10. The ability for users to add a description for per-participant sets has been included so the set is easier to identify.
  11. The width of SoECAT pages has been increased (decreased grey space) for improved viewing.
  12. Hyperlinks have been added to a number of automatically generated emails to enable users to go directly to the relevant SoECAT from the email.
  13. The ability for study representatives to revert their own SoECATs in order to make changes and resubmit for authorisation.
  14. The cost attributions for each visit on a per-participant set are now highlighted when they match the standard of care for an activity to allow easy comparison during review. This helps AcoRD specialists focus attention on the areas of the research that are different to standard of care, therefore hopefully reducing the time required to review the SoECAT. 

Functionality improvements to the SoECAT continue to be released and a mechanism for prioritisation of future user feedback is now in place to encourage the sharing of user improvement suggestions. Please submit your comments and suggestions for the future development of the SoECAT via our online feedback form.
