Learn about CORE


What is CORE?

CORE (Continuous Recording of Lettings and Sales in social housing in England) is a national information source funded by the Ministry of Housing, Communities and local Government that records information on the characteristics of both private registered providers and local authority new social housing tenants and the homes they rent and buy. Policy makers and practitioners regard the system as an essential tool for monitoring housing costs, assessing affordability and developing policy.

What information is available?

CORE provides information about new lets, sales and tenants. For example, household characteristics, economic status, ethnicity, primary reason for housing, source of referral and previous tenure of occupant. In addition, since information regarding housing costs is also recorded, broad assessments of housing affordability are also possible through CORE. (Please be advised that this information is confidential.)

Who collects the information?

The Ministry of Housing, Communities and Local Government took over the management of CORE from 2012. Data up to 2014/15 was collected via the TNS CORE website. MHCLG has taken responsibility for the collection of 2015/16 data onwards.

How do I participate in CORE?

See Participating in CORE for full details.

Is there training or documentation I can use?

Various training documents on how to use the CORE website and data requirements are available on the 'Guides and Manuals' page of this website (select the 'Learn about CORE' link at the top of the screen in the black-coloured banner - there is no need to log in to access this section). This will outline what information must be submitted for the CORE logs and how to do so.

How is CORE used?

Who uses CORE?

Information from CORE is used by a range of organisations to inform funding, regulatory and other policy decisions relating to the activity of private registered providers' and local authorities' activity and contributes to the wider policy debate. CORE data feeds directly into policy decision making of central government departments as well as being used by the Office of National Statistics in their price indices.

How should our organisation consider and address what user accounts we will need?

Your organisation will firstly need to inform us of your Data Protection Officer (DPO) by sending their name, e-mail address and direct dial phone number to the CORE Helpdesk. The Helpdesk will provide them with their log in details. DPOs will then need to download the General Data Protection Agreement, and then log in using the specific DPO user account details they will be given. (DPOs can download the Agreement without having to log in, but will then need to log in to select 'Administration' and then 'Data Protection Details' in the 'Institution' section.) The DPO should then click the box next to 'Confirm MHCLG agreement signed:' to denote the organisation has read and is now signing the Agreement on behalf of the organisation. The rest of the DPO's details on this page will then auto-populate. The DPO should then click on the 'Save' link.

Once your organisation has done this, the users you will then create new conventional accounts for can then begin supplying data for the organisation. (NB: If your organisation has agreements to provide data, or be provided with data, from other organisations, these other organisations will each need to complete the above DPO process as well, and you and/or the affected organisation(s) will not be able to proceed unless or until you and/or they do so.) So please check this with them or the CORE Helpdesk, who will be glad to help you here.

Your organisation can now consider which conventional user accounts to assign and create amongst your colleagues to supply data. There are two types of user account: Coordinator and Data Provider.

A Coordinator account holder should generally use their account to monitor and report on the logs that have been input by Data Provider account holders, create supported housing management groups and schemes and create new user accounts, although the CORE Helpdesk will be pleased to help with any of these. A Coordinator account holder is also generally considered to be a senior manager, supervisor and/or a team leader, the latter particularly where the organisation involved has many account holders. A Coordinator cannot access another Coordinator account holder's log forms.

A Data Provider account holder, as the user type's name suggests, should solely uses this account to input logs. The same-named person can be both a separate Coordinator and Data Provider account holder and there are no limits to the number of different Coordinator and Data Provider accounts that one organisation can have.

Please keep the CORE Helpdesk informed of any institution detail changes and any inactive user accounts, or if you are in any doubts about these.

How do I log into the CORE website and begin entering data?

Logging in is only required for registered users who want to submit CORE data. Please follow the instructions as detailed in Participating in CORE for full details. Once your organisation has been included on the CORE system, one of your Coordinators can then create a user account for you and can contact the CORE Helpdesk. if they need any help in doing so. Your Coordinator will then supply you with your login and password details.

I look to have finished inputting my logs. How can I check I have done so properly?

Data providers can check they have completed inputting and submitting CORE logs properly by selecting 'Administration' and then 'Your Logs'. They will then see, by selecting the appropriate reporting year and log type, the logs they have submitted. Logs should only appear in the 'Status' field as 'Valid' (which denotes they have been accepted in the system) or 'Dropped' (which denotes they have been deleted and removed). Logs that appear as 'Saved' (largely if input by 'Log Creation, i.e. individually) or 'Invalid' (largely if input by bulk uplaoding files) will still need attention. These logs show what errors have occurred at the appropriate point on the online form which is highlighted in red for the user, together with a summary of the errors involved at the bottom of the form, and can be accessed by selecting the 'Edit' link to the right of each log on the 'Your Logs' page. If all reasonable steps have been taken and the form is accurate but still showing errors, please contact the CORE Helpdesk with the Tenant Code(s) of the log(s) involved which may then have to be manually validated.

Analyse CORE data


How can tenants use this information?

The CORE datasets contain a variety of data to allow a wide range of analysis in a spectrum of topics, from weekly rents to the gender of household representatives or the reason for vacancy. MHCLG publishes data at national and local authority level (see Social housing lettings statistics) and deposits record level data in the UK Data Archive to allow further analysis. There is also interactive reporting available at Analyse CORE data.

What predefined analyses can I have access to?

Users can view data via predefined reports showing annual trends for all data for common variables at local authority level. Data Providers can also view their own data through predefined organisation reports.

How do I use interactive reporting?

There is an interactive reporting tool to see data at local authority level. Data has been protected to avoid identification and disclosure of sensitive information. Users can select which variable(s) to view at local authority level and view data for one or more local authorities. If data is not available for a particular local authority, this is because its data is considered disclosive, usually due to small totals.

The number of logs assigned to me/my team in certain download reports in the 'Your Data' section of the 'Analyse CORE Data' page is down on what I was expecting. What's causing this?

If you are a Coordinator, please check which Data Provider account holders should be linked to your account by selecting 'Administration' and then 'Manage My Institution's Users' and clicking and dragging the users' e-mail addresses from the inactive (left-hand) column to the right-hand (active) column (or vice versa if they are not required.

For all Coordinators and Data Providers, please bear in mind when running these reports that CORE issues them based on the date they were input, not the Tenancy Start date. The date range format for these reports should always therefore be 'From: 01/04/201X; TO: today's date', for example, (depending, of course, on what year the report is requested for) to automatically generate the maximum number of logs sought.



How can I feedback my views on this site and/or contact the CORE Helpdesk or MHCLG CORE Team more generally?

We welcome any feedback and ask that you please supply this via the CORE Helpdesk in the first instance. For any particular returns only that require a response to them directly, the MHCLG CORE Team can be contacted here
