Future Proofed DarkLight® Internet

DarkLight is the last internet connection you’ll ever need to install for your premises.

It's really that simple. Built around a unique dark fibre network, DarkLight delivers ultrafast, reliable and completely flexible connectivity to schools and businesses. Every single line can currently support a fully symmetrical 10 Gbps speed - that's more than practically any organisation will need for years to come, and it's a number that's just going to go up over time.

That means that once DarkLight is installed, you'll always be able to get the level of connectivity you need, as our team can upgrade the speed you're receiving with absolutely no additional construction work.

Following a recent upgrade to our network, DarkLight's recently got even better - our speeds now start at an incredible 300 Mbps, at absolutely no extra cost to customers, while our market-leading prices now offer even more exceptional value for money, starting at the equivalent of just £299 plus VAT a month.
