4th Utility

4th Utility, an independent full fibre operator in the UK

4th Utility presents itself as an independent internet service provider that deploys full fibre optic networks for homes and businesses across the UK. The company argues that poor connectivity has disrupted daily life and work across the country for too long, and positions its offering as an alternative to traditional operators. Its name refers to the idea that broadband is the essential fourth utility, alongside water, gas and electricity.

Own network and fibre optic technology

The key differentiator the company highlights is that it builds and maintains its own networks, which, according to its approach, frees it from relying on legacy technology. Unlike installations that use copper cable and telephone lines, 4th Utility uses fibre optic cabling that runs directly from the provider to the home, with no associated landline. The company belongs to the group known as alternative networks.

Among the technical advantages it mentions are symmetrical upload and download speeds, more stable connections and a reliability level it puts at 99.9%. The website advertises speeds of up to 2.3 Gbps and, in another section, up to 1 Gbps.

Packages and contract options

The offering is organised into different speed packages for users to choose from. As for terms, the company states that it offers flexible terms ranging from 30-day rolling contracts to 24-month contracts. The sign-up process it describes consists of three steps: check availability using a postcode checker, select the speed package and subscribe to the full fibre service.

Customer service and support

The company maintains a help desk with categories for billing and payments, broadband and account management. Among the topics it covers are payment methods, changing your password, changing your payment date, changing the account holder name, paper billing, cancelling the service, changing the package speed, problems with the router or wireless connection, slow speed, using your own router, setting up the WiFi network, Double NAT errors on Xbox consoles, compatibility with Sky Q and Sky Glass devices, and checking for service outages in your area. It also publishes self-installation guides for Icotera equipment and an explanation of the difference between broadband and WiFi.
