Well, I'm on 900mbps down and 900mbps up with Brsk and paying currently £32 per month. should have been £45 but they had a promotion. I can't see it being much more either around the £45 mark or possibly a little higher at £50 - £60.
On the one hand, you might think so. But, BTW are not even trying to compete with the cheaper wholesale altnets. Many ISPs sell both OR/BTW FTTP and also Cityfibre. The Cityfibre offering is cheaper for 1Gbit symmetric than the BTW 1Gbit asymmetric product.
Also looking at the current wholesale price-list, it's clear they are marking up the upstream far more than downstream. Which, kinda makes sense. They might not want to price gouge their own leased line products for business users.
While they're by far the biggest fibre wholesale provider out there, they can afford to do it too. I also wouldn't assume symmetric speeds on altnets (at least wholesale providers) will remain so cheap either. Once they become established, they might well also want to get a foot in the business sector too. Making their home grade products asymmetric would make sense then.
Time will tell, for the time being altnets want customers to fuel expansion and don't have a reason not to offer symmetric connectivity. BTW/Openreach are miles ahead in terms of deployment, so they don't really need to compete on upstream at the cost of their more lucrative business products.
But, that's not to say they might not decide to try to slow down altnets by stealing their customers by competing on price and upstream speeds.
We shall see.
