Our expectations

Supplier Access to BT's Sites and Buildings

Where contracted personnel of suppliers require access to BT sites or buildings, they must obtain authorisation by adhering to the BT Security Access Policy.

Why have an Access Policy?

BT has put in place processes intended to protect the assets of both BT and those of the supplier. These processes enable authorised unhosted access to BT's sites and buildings and allows the supplier to obtain access, cards and keys from BT either directly or via a BT Line Manager/Contract Liaison Manager (CLM).

When a contracted person from the supplier enters BT sites or buildings they should be aware of their obligations to maintain the integrity of BT's assets. A BT Security Handbook provides general guidance concerning the responsibilities of the contracted supplier to ensure that site security is maintained. It also gives advice on how to contact BT security and contacts for fault reporting.

What are the options for managing access to the BT Estate?

Option 1 (Redside) - Requesting access directly via the BASOL Redside System

This option provides the flexibility necessary for suppliers to administer their own requests for access to BT buildings and sites.

An Authorising Signatory (AS) and up to 10 delegates can apply for access, cards and keys on behalf of their employees/agents using the BASOL Redside System.

The AS and delegates are approved by a BT manager who sponsor's the company and is responsible for ensuring compliance with security policies.

  • The BT Sponsor will raise a request to the Access Control Team for the company to have access to the BASOL Reside System. An ASF1 form must be completed for each AS/delegate to provide the required information, assurance and approvals.

  • Up to date records of all personnel who need access to the BT estate for more than 28 days must be maintained using the HR process at This ensures that access, cards and keys can be managed effectively for the supplier's community.

  • Access, cards and keys can be requested using the BASOL Reside System.

Access and keys requested should be the minimum required for the person's role and access should be removed when it is no longer required.

During 2018 new card requests will require submission of a passport style photo so that a BT contractor photo ID card can be provided, until this is fully implemented a standard access card will be provided. You will be advised by the Access Control Management Team when the process change affects you.

  • For people with a short term or occasional access requirement, the AS can request approval to manage temporary access, cards and keys that can be allocated via BASOL Redside for a period of up to 28 days.

A BASOL Redside System User Guide will be provided and support will be available from the Access Control Management Team.

Option 2 (Greenside) - Obtaining access via a BT Line Manager/CLM

Suitable for smaller contracts where it is practical for a BT manager to administer access requirements for the contracted personnel.

Under this option a designated BT CLM can obtain all of the necessary access, photo ID cards and keys on behalf of the contracted personnel.

  • For people who need to access to BT sites for more than 4 weeks, a UIN should be requested via HR processes and the necessary access, photo ID cards and keys can be requested by the registered BT Line Manager using the BASOL system.

  • For people with a short term or occasional access requirement, the BT Line Manager (or a nominated representative) can request approval to manage temporary access, cards and keys that can be allocated via BASOL for a period of up to 28 days.

More detailed information regarding the application process, including all form referred to above, is contained in the BT Physical Access Application Process for non BT organisations.

Suppliers must exercise due care when recruiting employees within their own company or indeed when using employees of any other contractors or agents, who will have access to the BT estate. The employer must ensure that, when an individual is recruited, an employment application form is completed, references are obtained, self-declaration of criminal convictions signed and proof of identity validated (e.g. passport / birth certificate).

All people accessing the BT estate must be in possession of, and display, their own company photo ID if they not using BT provided photo I/ access cards.
