BT has generated £1 for every £80 produced in the United Kingdom, an independent survey has suggested.
A report conducted on behalf of BT by Regeneris Consulting' also found that BT spent £6.5 billion with UK suppliers during the 2014/15 financial year and gave an £18 billion boost to the country’s economy.
The national communications regulator Ofcom is currently debating whether it should listen to rival operators, such as Vodafone, TalkTalk and Sky Broadband, and separate the Openreach network from BT.
The move has been recommended by rivals due to allegations that BT has misused its position in the market and had under-invested in national infrastructure.
BT has since been trying to convince both Ofcom and the general public that it's current system is fit for purpose.
The latest findings are likely to have strengthened BT's argument, with the report adding the company is currently employing the equivalent of 217,000 full-time workers.
Brendan Dick, Managing Director of BT Regions, said: “There are few organisations that have a larger impact on the day-to-day life and future prospects of the UK than BT. We are one of the country’s largest private sector employers and investors – our investment in fibre broadband alone amounts to more than £3 billion – and the services that we provide are a vital part of every community.
"The facts and figures shown in this report highlight the full extent of BT’s contribution to the economy as we go about the daily business of keeping people connected and introducing new technologies, which are creating fresh opportunities and transforming lives."
The economic viability and impact on employment are both likely considerations for Ofcom's decision in potentially separating the company from Openreach, although concerns over quality service from rival firms will probably continue.
