Full-fibre broadband should be installed in all new-build homes, the government has stated.
Ministers want to ensure 15 million premises have access to the technology by 2025, with a view to achieving universal full-fibre coverage by 2033.
However, the government's Future Telecoms Infrastructure Review suggests that full-fibre broadband networks will only reach three-quarters of the country at most unless there is a significant policy change.
Furthermore, it noted that unless a new approach is adopted, it could take more than two decades to achieve this level of coverage.
With this in mind, ministers have called for new legislation that guarantees full-fibre connections to new build developments, which they say will be vital for underpinning 5G coverage.
Furthermore, the government wants to implement reforms to the regulatory environment for full-fibre broadband that will "drive investment and competition and is tailored to different local market conditions".
Jeremy Wright, the Culture, Media and Sport Secretary, commented: "We want everyone in the UK to benefit from world-class connectivity no matter where they live, work or travel.
"This radical new blueprint for the future of telecommunications in this country will increase competition and investment in full-fibre broadband, create more commercial opportunities and make it easier and cheaper to roll out infrastructure for 5G."
The pledge has been welcomed by Ofcom Chief Executive Sharon White, who said it shares the government's ambition for full-fibre and 5G networks to be rolled out across the country.
"The government and Ofcom are working together, and with industry, to help ensure people and businesses get the broadband and mobile they need for the 21st century," she said.
