We’re a London company exclusively serving the capital’s residents and businesses. We are leading the way in bringing future-proof, super-fast and reliable broadband at a fairer price.

We’re also passionate about giving back to the communities we serve. So far we've connected 600 community spaces with free 1 Gbps Fibre Broadband. We also train qualified Digital Ambassadors to help bridge the digital divide in London communities.

Unlike most providers, we build, own and operate our dedicated fibre optic network with the most reliable broadband technology you’ll find — 100% full fibre. It’s future-proof, energy efficient, sustainable, and is up and running over 99.9% of the time with no peak-time slowdowns. This means we don't have to rely on Openreach, or anyone else's, outdated copper cables.

With us, you get excellent rated service, incredible speeds and outstanding reliability right from the get-go.

Now that's better broadband for everyone.

Hi there! Thanks for stopping by our job ad.

We’re London’s largest and fastest 100% full fibre broadband provider, bringing better internet to Londoners since 2013. Unlike most providers, we build, own and operate our dedicated fibre optic network and install it directly into the home, meaning we can deliver a super-fast connection at prices the national providers find hard to beat. We’re a relatively new company to the market, but since establishment:

1. We’re the only broadband provider on the market offering residential speeds up to 3,000 Mbps.
2. Our network covers over 1.3 million properties in London, which is more than one third of homes in the UK’s capital city.
3. We have over 800,000 properties under wayleave agreement and are currently working in partnership with more than 200 of London’s biggest landlords.
4. We have freely connected over 600 community spaces in 24 boroughs, giving more Londoners free access to fast, reliable broadband.

We’re proud of our achievements so far, but we are not complacent and definitely not stopping here. To help us get to our future, we’re looking for forward thinkers, people with big ideas, people passionate about technology and most importantly hard working team players to join us and be a part of our growing business.
