How Long Does Security Clearance Take?

When you, your organisation or an employee has work pertaining to government or public projects, it’s sometimes necessary to obtain a security clearance (sometimes referred to as a Security Check). It might be that you’re involved in the import or export of controlled goods, for instance; or you’re contracted to work on government projects in the UK, and your operations will involve crossing the border. In situations such as this, to avoid risk and bolster national security, the UK government might require a security clearance process.

There are four main government security levels, as stipulated by the Ministry of Justice:

  • Baseline Personnel Security Standard (BPSS) / Enhanced Baseline Standard (EBS)
  • Security Check (SC)
  • Counter Terrorist Check (CTC)
  • Developed Vetting (DV)

With efficiency and speed so vitally important, this leads many to ask the question: how long does SC clearance take?

What is the Security Clearance Process? How to Get Security Clearance in the UK

In order to get security clearance, you must follow a process known in the UK as national security vetting (UK government). This involves a series of background checks about the applicant, their situation and personal history, and is used to determine any risks in granting access to potentially-sensitive material.

The government provides a vetting explainer on their website which contains more information. The vetting charter also provides information about what the applicant can expect.

Depending on the type of clearance being applied for, national security vetting can typically take from six to 18 weeks.

The security clearance process can be split into five sections:

1. Applying for / renewing security clearances

Note: this is not applicable to applicants for an Accreditation Check.

You need to have a sponsor with UK citizenship. This is usually a human resources officer, a personnel officer or security controller. The sponsor will confirm the need for security clearance and the appropriate level.

With this completed, the applicant will be given a link to complete a security questionnaire.

2. Activating the NSVS portal and submitting questionnaire

Again, this section is not applicable to applicants undergoing an Accreditation Check.

The government provides information and guidance on the National Security Vetting Solution (NSVS) portal on its website.

If the government requires further information, they will contact the applicant directly while they perform the necessary cross-checks.

3. The vetting interview

Vetting officers will contact the applicant to arrange a vetting interview, which typically takes around three hours.

The interview will consist of some questions concerning the applicant, their life and their personal history. Vetting officers conduct an interview in order to build a complete picture of the applicant, and determine factors such as:

  • Loyalty, honesty, reliability and vulnerabilities
  • Extended family background, including influences and relationships
  • History of drug taking (if any)
  • Financial affairs
  • General political views
  • History of foreign travel
  • Hobbies and lifestyle.

4. Decision processing

With the security clearance process completed, there will follow a period of adjudication, and a decision will be reached as to whether the applicant presents a risk to national security.

If officers deem the applicant unsuitable to be granted access to sensitive assets, they will deny security clearance; this signals that the application has been unsuccessful. In the event of clearance being denied, the applicant will be informed of the reasons why this decision was taken.

5. Appeals process

There is an appeal process available for applicants who have had their clearance withdrawn or denied.

What are the different types of Security Clearance?

Within the four levels of clearance (BPSS, SC, CTC and DV), there are seven separate types of clearances. Below, we’ll walk through each of the clearances in turn.

Baseline Personnel Security Standard (BPSS)

The BPSS is recognised as the standard security clearance for the pre-employment screening of individuals with access to sensitive government assets. Though not a formalised security clearance per se, its application is the foundation for further vetting processes.

An number of private companies offer BPSS checks, in line with government requirements. On average, BPSS checks take approximately 6 days.

Accreditation Check (AC)

AC clearances are needed for people who have independent access to controlled areas in UK airports and are typically valid for 5 years, provided the sponsoring organisation is in ongoing compliance with provision of data. Where this requirement is not met, AC checks last for 12 months. Some elements will be performed by the employer, an airport operator or air carrier.

Counter Terrorist Check (CTC) / Level 1B

CTC checks are needed for individuals who work in close proximity to public and government figures, or whose career brings them into contact with assets which might be vulnerable to terrorist attacks. CTC security clearance takes a minimum of 6 weeks, and must be formally reviewed after 10 years (or 5 years for non-List X contractors).

Security Check (SC)

This is required for people who will have far-reaching access to SECRET, or occasional controlled access to TOP SECRET assets. SC clearance asserts that the individual would not pose a risk in handling sensitive information. The answer to the question, how long does SC clearance take can vary, but on average the process will typically last for 6 weeks.

Enhanced Security Check (eSC)

Similar in nature to SC, an eSC grants regular uncontrolled access to SECRET assets, and supervised access to TOP SECRET information where necessary. It is used for roles where security clearance in excess of SC is needed, but not up to the level of DV.

Developed Vetting (DV)

Developed Vetting is the highest level of security clearance, intended for individuals with regular uncontrolled access to TOP SECRET assets. It would also be required for those working in high-level Intelligence or Security services. DV must be formally reviewed at intervals not exceeding 7 years, and will take a minimum of 18 weeks to obtain.

Enhanced Developed Vetting (eDV)

The only remaining security clearance level is Enhanced Developed Vetting, limited and available to a very small number of individuals. It will only be considered where an exceptional amount of unrestricted access is required to TOP SECRET information, justifying the necessity of clearance in excess of DV level.

eDV may only be requested by an extremely limited number of Sponsors, and only by prior agreement with UKSV and the Cabinet Office.

SC Clearance Eligibility & Requirements

With the basic information regarding each SC clearance established, we’ll turn our attention to the eligibility criteria, extent of asset access, and relevant checks pertaining to each SC level.

Baseline Personnel Security Standard (BPSS)

Any individual with access to government assets will need BPSS. This would include civil servants, military personnel, temporary department staff, and any government contractor.

They will gain authorisation to access:

  • UK OFFICIAL assets and occasional access to UK SECRET assets
  • Possible entry into areas where SECRET and TOP SECRET information may be discussed
  • Individuals requiring access to Public Services Network (PSN).

BPSS checks will involve:

  • The applicant’s identity
  • Employment history of the past 3 years
  • National and immigration (right to work) status
  • Any unspent criminal record
  • An account of any period spent abroad exceeding 6 months within the past 3 years.

Accreditation Checks (AC)

AC clearances are needed for any persons fulfilling work responsibilities or a job role which:

  • Necessitate an Airport Identification Card or UK air carrier Crew Identification Card
  • Facilitate UK aviation security training
  • Perform validation procedures of air cargo security standards.

Accreditation Checks will involve the verification of:

  • The applicant’s identity
  • Employment and education history (including gaps) of at least the past 5 years
  • Any unspent criminal record
  • A cross-reference against UK government records or related agencies.

Counter Terrorist Check (CTC) / Level 1B

People whose work brings them into close proximity with public figures deemed to be at risk from terrorism will require CTC clearance.

They will gain authorisation to access:

  • Some information judged to be vulnerable to terrorist exploitation or of value to terrorists
  • Unsupervised access to some military, civil, industrial or commercial locations deemed to be vulnerable to terrorist attack.

CTC checks involve:

  • Completion of the BPSS
  • Completion of a security questionnaire
  • Departmental/company records checks
  • A check on criminal conviction history
  • A check of MI5 records
  • In some cases, an interview.

Security Check (SC)

If an employee has frequent, unsupervised access to SECRET or periodical access to TOP SECRET information, they will need SC clearance. SC clearance is also required for people who:

  • Could be in a position to cause a similar degree of damage while not occupying the role
  • Have sufficient knowledge to build an accurate picture of SECRET data or information
  • Are a candidate for employment where career progress would be inhibited without SC for SECRET assets
  • Might need access to classified material originating overseas.

Security Check processing will consider elements such as:

  • Successful completion of the BPSS Baseline Personnel Security Standard
  • Completion of a security questionnaire
  • Departmental/company records
  • Spent and/or unspent criminal records
  • Credit and financial history
  • MI5 records
  • Possibly, an interview
  • in the event of unresolved financial matters, a separate financial questionnaire

Enhanced Security Check (eSC)

An Enhanced Security Check would be needed for an individual requiring to access SECRET and (occasional access to) TOP SECRET assets, but not requiring full DV clearance. It is only available to holders of:

  • Positions where there is a necessity to access SECRET code word material
  • Positions that have been designated as needing eSC clearance
  • Overseas positions that expose the employee to espionage threats and/or a lower level of management oversight.

The following checks may be involved in eSC:

  • Completion of the Baseline Personnel Security Standard
  • Completion of Security / Financial / Internet Questionnaire
  • a departmental/company records check
  • Spent/ unspent criminal records
  • Financial history
  • MI5 records
  • A detailed interview
  • An assessment of assets, liabilities, income and expenditure, including those pertaining to a spouse or partner.

Developed Vetting (DV)

Only those individuals needing regular and substantial, independent access to TOP SECRET classified information, or relevant codewords, would need to seek DV clearance.

Similarly, if a person might:

  • conceivably affect a similar amount of damage while not the official holder of a post
  • require frequent uncontrolled access to Category 1 nuclear material, or
  • be privy to high-level overseas classified data they may need DV clearance.

DV checks involve the following procedures:

  • Successful completion of the BPSS
  • Completion of a DV security questionnaire
  • Departmental/company records checks
  • A check of spent and unspent criminal records
  • A check of credit and financial history
  • A check of Security Service (MI5) records
  • A review of personal finances
  • A detailed interview and further enquiries
  • A full review of personal finances taking into account the joint position with a spouse or partner.

Enhanced Developed Vetting (eDV)

As stated, only a very small number of posts may request or hold eDV clearance.

eDV checks involve:

  • Completion of a DV security questionnaire, including a family and travel element
  • A full criminal record check
  • A Security Services check
  • A credit reference check
  • A financial investigation
  • An applicant interview
  • A supervisor interview
  • A referee interview
  • A full review of personal finances, taking into account the joint position with a spouse or partner.

If you’re wondering how long does security clearance take, or have any other questions about the process, don’t hesitate to contact our team today.

How long does security clearance last?

BPSS checks do not expire, though they may be repeated by new employers.

Security Check (SC) classification is valid for 5 years for government contractors and 10 years for permanent employees. Moreover, it is transferable between departments.

Can you fail SC clearance?

To put it briefly: yes, it is possible to fail SC clearance.

This means the individual’s application has been unsuccessful, and access to relevant assets denied. There are a number of reasons why a clearance application may be unsuccessful, including:

  • The existence of a criminal record
  • Issues surrounding citizenship
  • Financial irregularities, inconsistencies or instabilities
  • An incomplete or inaccurate application
