At my previous flat 150mbps was the fastest available. So it varies a lot in London on where exactly you are.
We are still creating newbuilds in cities without fiber. In other news, someone fucked up construction and left an entire complex of brand new apartment blocks with 7 mbps internet

Just fyi as I know you aren’t a native speaker, it’s ‘chip in’, if you were native I’d assume a typo, probably is for you too, but it’s a phrase easy to mishear and when I was learning a second language I appreciated these corrections.
We moved back to NL and have 1GBit fiber, and there has been a short outage once in three years. I know that there are a still a lot of addresses without fiber, but when I last checked the stats, about 50% of the addresses has the possibility to get a fiber subscription. Heck, even my parents who live in a small rural town have fiber.
I wonder how the upgrade might look considering that 10Gbps hardware is quite expensive (and house cabling might need upgrading) and 2.5Gbps/5Gbps is quite new and hard to find router or laptop dock/hub supporting it.
