FibreNest Reviews

I was super skeptical about switching to Fibrenest. I mean, I didn't really have a choice since it was a new build Persimmon Homes development.
I read a ton (ha ha like 2) of (old) reviews online and had many sleepless nights thinking I was downgrading big time. You see, I was on the 2Gbps YouFibre package at my old place, which was perfect for my homelab shenanigans. I was sure moving to this "Terrible ISP" was going to be a disaster.
Fast forward to today, and I've been a Fibrenest customer for just about 3 weeks. And guess what? It's been... perfect. I went with the 900Mbps package, and the ONLY downside is the price. Going from paying £54 a month for a 2Gbps package with a static IP to now paying £59 for a 900Mbps package with a static IP does sting a bit. But hey, I'm hoping this is short-term pain for long-term gain.
Their support is pretty good too. Even though I'm in the industry and probably know more than the average call center agent, they don't come across as arrogant. If I mentioned something they didn't understand or questioned their scripted response, they accepted it and offered to connect me with their technical team. The call agents I've spoken to have been really kind, understanding, and willing to help.
It's 2025, and I'd say Fibrenest has come a long way since the early 2020s. Their pricing could be better, but I guess they know the

As most who have had to go with FibreNest (Persimmon), it was our only option due to the monopoly they have on the provision of internet services on their estates. The service was great as it just worked from the day we moved in for basic internet usage but once I needed to do anything more I found the issues. As the other reviewer has said, I'm being told that the static IP I bought the highest package for isn't technically available. This means that I'm unable to allow any inbound connections into my network. I can't comment on what impact this has with gaming but I've heard that its not good. I've also tried to use my own router as they say you can but it just doesn't work. I've given up even trying and I just want the service out. I'd rather use a 5G connection than give them any money.

If they'd just remove the option of a static ip then I would still be disappointed but wouldn't feel like I've been taken for a ride buying a service that doesn't exist (or is being "worked on" indefinitely). I've reported this to Ofcom as this can't be right.

I'm just hoping that once the estate is finished, we can get a proper ISP to put their infrastructure in.

Having moved into a new-build Persimmon house, I found out that my only option for Broadband (or, indeed, any internet connection at all) was Fibrenest which is run by... Persimmon. I had a look at the price list (https://www.fibrenest.com/pricelist) and decided to go with the fastest connection, which had the added bonus of a free public IP. I signed up and set up the direct debit. They promised the broadband to be activated on the day we moved in (which in fairness, it was), and all was well or so I thought.

It turns out Fibrenest uses CG-NAT (carrier-grade NAT), meaning you're essentially double-NATed, so opening ports to the internet isn't possible. You don't have a direct connection. Furthermore, that public IP that they promise? After I raised a support ticket asking for my public IP, I was told it isn't possible on their network and I wouldn't be getting one. I also haven't been able to use my own router in place of their Linksys router as it never gains a WAN IP or a connection to the network.

Speeds are ok - the network gets quite congested during the evenings and speeds suffer as a result suggesting poor investment in what is quite a small network. I've also been cut off in the middle of the night for short periods of time without explanation. Realistically, it's not the worst ISP, but far from the best. Mis-selling and a monopolised sale makes it a bitter pill.
