Other important information

Cautions and convictions that must be declared

When accepting contracts of employment with the College, individuals whose appointments are subject to a Disclosure and Barring Service (DBS) check are required to confirm that they have been open and transparent about their past and have fully declared any convictions, cautions, reprimands or final warnings that are not "protected" as defined by the Rehabilitation of Offenders Act 1974 (Exceptions) Order 1975 (as amended in 2013) by SI 2013 1198. The following must be declared:

  • Cautions relating to an offence from a list agreed by Parliament – see below
  • Cautions given less than 6 years ago (where individual over 18 at the time of caution)
  • Cautions given less than 2 years ago (where individual under 18 at the time of caution)
  • Convictions relating to an offence from a prescribed list - see below
  • Where the individual has more than one conviction all convictions will be included on the certificate (no conviction will be filtered)
  • Convictions that resulted in a custodial sentence (regardless of whether served)
  • Convictions given less than 11 years ago (where individual over 18 at the time of conviction)
  • Convictions given less than 5.5 years ago (where individual under 18 at the time of conviction)

The above mentioned list includes a range of offences which are serious and which relate to sexual offending, violent offending and/or safeguarding. It would never be appropriate to filter offences on this list. A list of offences which will never be filtered is available on the DBS website.

This is not the complete list as the legislation also extends to cover similar offences committed under the law of Scotland and Northern Ireland or under laws relevant to the armed services.

Policy statement on the secure storage, use, retention and disposal of disclosures and disclosure information

The following guidelines specify the correct handling and safekeeping of Disclosure information, and are in line with the College's Policy Statement on the Recruitment and Employment of Ex Offenders.

General Principles

As an organisation using the DBS Disclosure and Barring Service (DBS) to help assess the suitability of applicants for positions of trust, Imperial College London, complies fully with the DBSDBS Code of Practice regarding the correct handling, storage, retention and disposal of Disclosures and Disclosure information. The College also complies fully with its obligations under the Data Protection Act 1998.

Storage and access

Disclosure information will be kept securely, in a lockable, non-portable, storage container by the HR Division, separately from the individual's personnel file in line with DBS requirements. In accordance with section 124 of the Police Act 1997, Disclosure information is only passed to those who are authorised to receive in the course of their duties. Access is strictly controlled and limited to those who are entitled to see it as part of their duties, for instance to College employees directly involved in the recruitment process and designated HR Managers. Passing on Disclosure information to anyone who is not entitled to receive it could be considered a criminal offence


Disclosure information will only used for the specific purpose for which it was requested and for which the applicant's full consent has been given.


Once a recruitment (or other relevant) decision has been made, the Disclosure information will not be retained for longer than is necessary. In general this will be for a maximum of 6 months from the date of issue of a Disclosure, to allow for the consideration and resolution of any disputes or complaints.

If, in very exceptional circumstances, it is considered necessary to keep Disclosure information for longer than 6 months, the DBS will be consulted about this.


Once the retention period has elapsed, the College (HR Division) will destroy the Disclosure information by secure means, for example by shredding. The College will not keep any photocopy or other image of the Disclosure. However, the HR Division will keep a record of the date of issue of a Disclosure, the name of the subject, the level of check, the position for which the Disclosure was requested, the unique reference number of the Disclosure and the details of the recruitment decision taken.

Lost Criminal Records Checks

If a Disclosure information document is lost, the College will immediately inform the DBS.

Imperial College London is committed to a policy of equal opportunities in employment whereby individuals are selected, trained, promoted and treated on the basis of their relevant merits, skills and competency.

It undertakes not to discriminate unfairly against any subject of the Disclosure on the basis of conviction or other information revealed. A copy of the DBS Code of Practice can be made available on request.

  • Where details of convictions are required, they will be obtained in conjunction with the successful applicant / member of staff via the DBS.
  • Where criminal records checks are required for applicant/staff they will be undertaken by the HR Division only. All information received as part of this process will be treated as highly confidential and in line with the College's Policy regarding the Security, Storage and Retention and Disposal of Disclosures and Disclosure Information, as required by the DBS.
  • For those positions where a disclosure is required, all job adverts and person specifications will contain a statement that a Disclosure will be requested in the event of an individual being offered the position.
  • A criminal record will not be an automatic bar to employment at the College. The relevance of the offence to the duties of the post will be considered before a final decision on suitability is made. The College ensures that an open and measured discussion takes place on the subject of any offences or other matter that might be relevant to the position.
  • Failure to reveal information on criminal convictions, at the initial application stage, that is directly relevant to a position may lead to the withdrawal of an offer of employment.
  • Staff are required to notify the Head of Department/Division of any current criminal conviction. Staff are not required to notify spent convictions. Information on convictions occurring during employment will not be used for disciplinary purposes unless it impacts upon the role and responsibilities of the post which the member of staff holds.
