If you live in the south, unless you're in a rural area, we don't often get frost before end of October early November. You can leave your fuchsias another couple of weeks quite safely, but perhaps best to do it after this hot spell we're having disappears and the weather becomes cool and murky again.

I usually leave mine out until we have serious frost, so probably mid to late October, but if any degree of frost is forecast then I sling that very light webby stuff over them at night (the name escapes me....). It even keeps them going in the Czech Republic where frost appears much earlier than in the UK.

Mine (all 30 of them) are just launching into a completely fresh set of flowers, much to my surprise and delight. I have a horde of visitors coming during October so that I very much want them to still be in flower.
