Which provider offers the fastest Internet connection in UK?

As of my knowledge cutoff date in September 2021, the fastest Internet connection in the UK was offered by Virgin Media, with speeds of up to 1.2 Gbps (Gigabits per second). However, it's important to note that Internet speeds may vary depending on location and infrastructure. Additionally, new providers and technologies may have emerged since then, and it's best to consult the latest information from local Internet service providers to get the most up-to-date information.
