decided that telecommunications should be fully separated from the Post Office. The ''British Telecom'' brand was introduced in 1980. On 1 October 1981, this became the official name of Post Office Telecommunications, which became a state-owned corporation independent of the Post Office under the provisions of the
British Telecommunications Act 1981. In 1982 BT's monopoly on telecommunications was broken with the granting of a licence to
Mercury Communications.
Privatisation
On 19 July 1982, the Government announced its intention to sell shares in British Telecom to the public. On 1 April 1984, British Telecommunications was incorporated as a public limited company (plc) in anticipation of the passing of the Telecommunications Bill. This Bill received royal assent on 12 April as the
Telecommunications Act 1984
The Telecommunications Act 1984 (c. 12) is an Act of the Parliament of the United Kingdom. The rules for the industry are now contained in the Communications Act 2003.

, and the transfer to British Telecommunications plc from British Telecom as a statutory corporation of its business, its property, its rights and liabilities took place on 6 August 1984. The remainder of the statutory corporation British Telecom was dissolved in 1994.
Initially all shares in the new plc were owned by the Government. In November 1984, 50.2% of the new company was offered for sale to the public and employees. Shares were listed in London, New York, and Toronto and the first day of trading on was 3 December 1984. The Government sold half its remaining interest in December 1991 and the other half in July 1993. In July 1997, the new Labour Government relinquished its Special Share ("Golden Share"), retained at the time of the flotation, which had effectively given it the power to block a takeover of the company, and to appoint two non-executive directors to the Board.
The company changed its trading name to "BT" on 2 April 1991. In 1996

At its height, the Concert managed network was extensive. Although Concert continued signing customers, its rate of revenue growth slowed, so that in 1999 David Dorman was made CEO with a brief to revive it.
In late 2000, the BT and AT&T boards fell-out, partly due to each partner's excess debt and the resulting board room clear-outs, partly due to Concert's extensive annual losses. AT&T recognized that Concert was a threat to its ambitions if left intact, and so negotiated a deal where Concert was split in two in 2001: North America and Eastern Asia went to AT&T, the rest of the world and $400M to BT. BT's remaining Concert assets were merged into its BT Ignite, later BT Global Services group.

) to around 25% of the Country, with the rest catered for by the slower fibre-to-the-cabinet (FTTC), which uses copper wiring to deliver the final stretch of the connection.

Although BT had notified the UK government in 2003 of Huawei's interest in their £10bn network upgrade contract, they did not raise the security implications as BT failed to explain that the Chinese company would have unfettered access to critical infrastructure.

was supplied with an in-depth report indicating that the intelligence services had very grave doubts regarding Huawei, and that UK governmental, military, and civilian privacy may have been under serious threat.
On 7 June 2013, British lawmakers concluded that BT should not have allowed Huawei access to the UK's communications network without ministerial oversight, saying they were 'deeply shocked' that BT did not inform government that they were allowing Huawei and ZTE, both with ties to the Chinese military, unfettered access to critical national systems. Furthermore, ministers discovered that the agency with the responsibility to ensure Chinese equipment and code was threat-free was entirely staffed by Huawei employees. Subsequently, parliamentarians confirmed that in case of an attack on the UK there was nothing that could be done to stop Chinese infiltration.
By 2016 Huawei had put measures in place to ensure the integrity of UK national security. Specifically their UK work is now overseen by a board that includes directors from GCHQ

ZTE, another Chinese company that supplies extensive network equipment and subscriber hardware used with BT 'Infinity', was also under scrutiny by parliament's intelligence and security committee after the US, Canada, Australia and the European Union declared the company a security risk.
In 2020 following a government ruling, BT began removing Huawei equipment from its broadband and mobile networks in order to comply with new restrictions on the usage of Huawei equipment. As of 2023, the process is still ongoing.
Alleged complicity with drone strikes in Yemen and Somalia
In September 2012, BT entered into a $23 million deal with the US military to provide a key communications cable connecting RAF Croughton, a US military base on UK soil, with Camp Lemonnier
Camp Lemonnier is a United States Naval Expeditionary Base, situated next to Djibouti–Ambouli International Airport in Djibouti City, and home to the Combined Joint Task Force – Horn of Africa (CJTF-HOA) of the U.S. Africa Command (AFRICOM). ...

, following their refusal to explain whether or not their infrastructure was used to facilitate drone strikes. The subsequent refusal of this complaint was appealed in May 2014, on the basis that the UK National Contact Point's decision did not follow the OECD Guidelines. The issue of bias was also raised, due to the appointment of Lord Ian Livingston as government minister for the department which was processing the complaint: Livingston had occupied a senior position at BT when the cable between RAF Croughton and Camp Lemonnier was originally built.
Overcharging
In February 2017, a review of the telecoms market by Ofcom found that BT's landline only contracts provided poor value to customers. Ofcom ordered BT to reduce their prices but stopped short of demanding that customers were compensated. In January 2021, Law firm Mishcon de Reya filed a claim with the Competition Appeal Tribunal against BT worth £600 million, accusing them of historic overcharging on landlines. The class action lawsuit claims BT have increased their prices for line-only services every year since 2009, whilst the wholesale cost for delivering these services has reduced. The claimants suggest that customers could be entitled to compensation of up to £500 each.
Bidding rules violation
In 2020, BT was fined £6.3m by the telecoms regulator Ofcom for violating the law on a large public sector deal in Northern Ireland. Under Ofcom's regulations, the BT network shall handle all wholesale customers similarly. In its report, Ofcom found that BT's network violated the rules by failing to supply Eir with the same details on its on-demand fiber-to-the-premises offering as its own rival team.
OFCOM fines for non-functioning 999 calls
On 25 June 2023, a "catastrophic failure" in BT's network resulted in nearly 14,000 attempted 999 emergency calls not being connected. Ofcom fined BT £17.5 million, citing the telecom giant's lack of preparedness and poorly documented backup procedures.
