BT is the only UK telecoms operator apart from KCOM Group Ltd to have a Universal Service Obligation,[2] which means that a basic fixed telephone line must be provided at an affordable price to all citizens in the UK. BT is also obliged to provide public telephone boxes.[3]
Sales are distributed throughout the UK (82.9%); Europe/Middle East/Africa (10.5%); (Americas (4.2%); Asia/Pacific (2.4%); and break down as follows:
- 48.7%: Telecommunication services: primarily fixed and mobile telephony, Internet access and TV broadcasting for individuals and companies and professionals (telecommunication operators, Internet service providers, etc.);

- Internal service unit
- Technology – responsible for the innovation, design, test, build and operation of BT's global networks and systems
Subsidiaries
BT Openreach
There is no regulatory enforced structural separation of a network in the UK. However, Ofcom required BT to legally separate from its network division, Openreach in early 2017. Openreach supplies access to BT's network to other communications providers, and the purpose of the legal separation is to create a more independent Openreach which will work in the interest of all providers.[1]
- Jan.09.2020: Ofcom puts pressure on BT over fibre network. OfCom has called on BT to commit to accelerating the introduction of faster broadband networks. OfCom launched a consultation to encourage investment in full-fibre broadband infrastructure as it seeks to meet Boris Johnson’s election pledge to connect all the country’s homes “to gigabit speeds” by 2025. The consultation, which ends in April, will regulate BT’s Openreach broadband infrastructure network from Apr.2021-Mar.2026. Only 10% cent of the country has access to full-fibre broadband. Note: in areas where fibre competition exists, pricing will be left to the market; and BT will be allowed to charge an extra £1.50 - £1.85 per month for fibre to the premises, even if speeds are no faster than the 40 megabytes from the best-performing copper wires.ref Alex Ralph, The Times.
- 2006: Established following an agreement between BT and the Telecoms regulator OfCom to implement certain undertakings, pursuant to the Enterprise Act 2002, to ensure that rival telecom operators have equality of access to BT's local network. Openreach owns and maintains the telephone wires, ducts, cabinets and exchanges that connect nearly all homes and businesses in the UK to the national broadband and telephone network.
- Apr.25.2018: Cityfibre takeover deal frees it to challenge BT Openreach. Cityfibre, which has networks in 42 cities, has accepted a go-private bid from West Street Global Infrastructure Partners, a fund managed by Goldman Sachs, and Antin Infrastructure Partners SAS, a European private equity firm. Cityfibre’s biggest investors, representing 57% of shares, include Invesco Asset Management, Woodford Investment Management Ltd, Pelham Capital Ltd and Jupiter Asset Management Ltd.

- Nov.16.2018: EE, Virgin Media hit with £13.3m fine: Squeezing users for fees for early contract termination not OK. EE: We're sorry, OfCom. Virgin: Why, that's... unjustified and disproportionate! OfCom slapped a £13.3m penalty on EE (£6.6m) and Virgin Media (£7m) for fleecing customers who wanted to exit their broadband or mobile phone contracts before they were due to expire. Paul Kunert, The Register. See also Overcharging leads to big fines for EE and Virgin Media.

Articles
- Dec.19.2018: BT to shake up executive pay after shareholder revolt on chief’s bonus. BT has moved to pacify shareholders after it suffered a revolt over the £2.3m pay package for Gavin Patterson, its departing boss. BT said yesterday that despite its remuneration committee using discretion to reduce the bonus, investors still “felt that the amount paid did not appropriately reflect the underlying performance of the company or take adequate account of the value created for shareholders. BT stopped short of clawing back any of the bonus, but said it would “take steps to implement a more structured process to help it step through the application of its discretion in the future”. Alex Ralph, The Times.
- Oct.26.2018: ‘Out of this world pay’ for BT boss. BT under fire for handing new chief executive Philip Jansen a “stratospheric” pay and bonus package worth more than £8m a year - while cutting 13,000 jobs as part of a restructuring designed to spur revenue growth. Jansen joins BT at a time of turmoil after years battling OfCom, the industry watchdog, over its Openreach division, which owns the broadband network. The group is under pressure to invest more in its network, maintain its generous dividend payments and fill a large deficit in its pension scheme. Simon Duke, The Times.
- Jun.23.2018: Rake over the coals. Should Sir Mike Rake have attended a meeting last year to decide BT’s new auditor? On the face of it, obviously not. Yet to say Sir Mike influenced BT to pick his old shop is probably going a bit far. For starters, he’d left the firm 10 years before — without any KPMG pension. And the well-connected Sir Mike has been on enough boards since — Barclays, easyJet plc, Worldpay, CBI president — to know how to manage conflicts. ... Alistair Osborne, The Times.
- Jun.23.2018: BT chief denies audit conflict. Sir Michael Rake, chairman of BT until Nov.2017, was involved in the process to appoint KPMG as its auditor, despite an apparent conflict of interest because he had led the Big Four accountancy firm for ~10 years. The revelation will also raise concerns about BT’s governance. KPMG was named as BT’s auditor in Jun.2017 after the telecoms group ended its relationship with PwC following the discovery of a £500m fraud at BT’s Italian business. Accountancy regulator Financial Reporting Council this week accused KPMG of an “unacceptable deterioration” in its audits. KPMG also has been criticised by MPs for “cursory” audits of Carillion. Sir Michael siad he had “no part in a recommendation” to go with KPMG and had been asked to attend the meetings by Nick Rose, head of the audit committee. Deloitte was dropped by SIG, a construction company, in May after 78% of shareholders voted against it; it had emerged that SIG had overstated its profits for years. Tabby Kinder, The Times.
- Jun.09.2018: BT targets outsider as new chief. BT is looking for outside candidates to be its next chief executive after sacking Gavin Patterson yesterday. The telecoms group announced plans to replace Patterson only a month after the board had backed him to a lead a big restructuring. BT has embarked on its biggest shake-up in a decade, cutting 13,000 jobs and vacating its London headquarters. However, Jan du Plessis, chairman since Nov.2017, has decided that “there is a need for a change of leadership to deliver this strategy”. Alex Ralph, Miles Costello, The Times.
- Mar.16.2018: Embattled BT forced to call in consultant as head of strategy. BT moved to strengthen its management team yesterday with the appointment of Michael Sherman to a newly-created role of chief strategy and transformation officer, as the telecoms giant battles to draw a line under a difficult period for the group. It has been under mounting political pressure to invest more in the rollout of full fibre internet connections to more UK homes. Last year it was forced to legally separate its wholesale broadband division Openreach from the rest of the company. Robin Pagnamenta, The Times.
- Jul.19.2017: Ofwat chief quits for private sector job. Cathryn Ross is leaving at the end of the year to join BT and lead its battle with telecomms regulator OfCom. Cathryn Ross, who has run OfWat for nearly 4 years, is to head BT's regulatory affairs operation. The telecoms firm has had a bad year, marked by an accounting scandal in Italy and a record £42m fine from OfCom for overcharging for broadband access in the UK. more Julia Kollewe, The Guardian.
