Superfast Fibre BroadbandThe Big Build

Superfast fibre is lighting up the UK

Covering 30 million customers, our network supports 300 million telephone calls and 350 million internet connections every day. And our network upgrade, one of the biggest and fastest in the world, is helping the Government achieve its aim of reaching 95 per cent of UK premises with superfast fibre broadband by the end of 2017.

More than 23 million homes and businesses already have access to fibre broadband, with around 60,000 being added each week. And our network is open to all service providers, meaning people have plenty of choice over who to buy from. Thousands of our engineers work every day to plan and install the equipment needed to make this possible. The scale of our fibre programme is massive. But we know we still have more to do.

Is your area accepting orders, or do you live in an enabled area?

If your area is accepting orders, contact a service provider today to order fibre broadband.

If your area is enabled but your cabinet isn’t ready, you can't place an order today. We are planning to upgrade it, so check back soon.

Is your area under review, or are we exploring solutions for your area?

Check our rural broadband page explaining which regions are covered by the Government’s BDUK roll out. If you see your region listed, visit that regional website for more info.

If your area isn’t covered by the Government’s BDUK roll out, you might want to consider co-funding fibre access in your community.

The key stages from planning to go live

Once we start preparing an exchange to be enabled, it is typically 10 to 15 months (but could be longer) before it's ready to supply superfast fibre broadband to one or more street cabinets in the area. Why? Here's what’s involved.

Pre Planning

The most important thing is to know what the current picture is like in an exchange area. So we do a full assessment of the existing network infrastructure to provide accurate, up-to-date information for engineers.

Months 1-9: Preparing the exchange

We then agree and plan where the new equipment goes. As every exchange is different, we may have to create bespoke equipment. Once ordered and built, we install everything and upgrade the power facilities.

Months 3-9: Planning the network

While we're upgrading the exchange, we survey the area and draw up a plan for where the fibre, new ducts and street cabinets go. This often involves consultation with local councils to comply with local planning regulations. Cabinets themselves can be subject to delays (see our FAQ to learn more).

Months 10-15: Installation

The final stage is building from the exchange to new street cabinet locations that have passed the planning stage. When the first 10 cabinets are ready, we tell our customers so they can start to offer fibre broadband services to homes and businesses.

What's so great about fibre?

The network that delivers today's phones and broadband is an all-copper infrastructure. But that means the further from the exchange you are, the slower your broadband speed.

Fibre is different. A single fibre is capable of carrying much more information than copper, and can do so in a far shorter space of time. It’s also more reliable and longer lasting, too.
