I’m not convinced, with FTTP pushing connection speeds beyond 1Gb it’s important to be with a provider who can run a network. You need someone who when told about packet loss or a degradation of throughput will investigate it rather than telling you that the guaranteed rate is only 250Mbps or that nobody else has reported it so they’re going to send a new router.
I am in the privileged position where an additional £5 each month is not a deal breaker, and having to deal with incompetence drives me mad.
