BT is given all clear by Ofcom to roll out new wholesale broadband pricing

But this was only if they agreed to use mainly Openreach’s full-fibre products for new orders instead of its legacy copper products.

The plans – called Equinox 2 – were criticised by BT’s competitors, such as Virgin Media O2.

An Ofcom spokesman said: “Our overriding objective is to bring better broadband to people across the UK, by promoting competitive investment in high-speed networks and making sure there’s a level playing field for all companies.

“With this in mind, and based on the evidence available to us, we don’t consider Openreach’s new pricing discounts to be anti-competitive.”

It said it had taken into account the impact of the pricing plans on consumers, rival broadband providers and so-called altnets – which are new fibre builders.

Ofcom added that by not blocking the plans, BT is able to “engage in network-based competition, without compromising our objective of promoting investment in gigabit-capable networks”.

Openreach has also pledged not to change its pricing under the plans until at least March 31 2026, according to Ofcom.

Katie Milligan, chief commercial officer at Openreach, said: “This is good news for customers as it means lower prices and long-term certainty – encouraging the switch to faster, more reliable broadband connections.

“It’s also good news for the UK, as it supports our continued multibillion-pound investment in upgrading the country’s broadband infrastructure.”

But the pricing deal has raised concerns among some rivals about Openreach’s move to discuss and develop discounts with retail providers.

“Having carefully assessed information from providers and altnets, we do not have concerns that warrant further investigation at this time,” Ofcom said. Ofcom had delayed its final decision that was due in March, which put back Openreach’s plans to launch the new pricing structure on April 1.
