Upgrade query

[Bill]

At the beginning of the year FTTP became available here^*; I went with the Home Fibre 115 package as my 80/20 FTTC had always been plenty fast enough for my needs.

I still don't need anything faster, but having since cancelled the BT copper contract I've now got some spare cash to pay for a bit of bling in the form of some more impressive speed tests 

Question- will a change of speed be more or less seamless or will there be any significant interruption to the service?

* FTTP from Gigaclear had been available a lot earlier, but with CGNAT and no IPv6 I didn't regard it as a "proper" internet connection

I upgraded mine when the cost of my original service actually exceeded the cost of a faster connection.  There was no interruption to service as far as I can recall, but I think I rebooted my router anyway, just for good measure.

That's good enough for me, I don't count reboots 

Thanks.

I've had a few service changes/upgrades and don't recall any interruptions although there's always the possibility I stepped away from the computer for a minute or two!

I thought it would probably be easy, but I'm a newbie to this FTTP lark so thought I'd ask
