We are heavy users so opted for 1000/115 from Zen Business. We ran this alongside another full fibre connection.
We had issues with Zen from the beginning. Our activation date came and went, but nothing worked (existing ONT). Zen support couldn't sort it so an Openreach engineer was booked and got the Zen connection on-line.
The connection consistently underperformed. The best achievable throughput was never more than a third the package download speed. Initially Zen were up against Openreach and their COVID restrictions. This caused significant undue delays.
After a few confused engineer visits Openreach eventually demonstrated the physical connection was okay and the issue was with Zen. Given our other FTTP connection (from a different ISP) always worked to pretty much the full 1000Mbps download this didn't come as a surprise.
Zen support were mediocre and certainly not industry leading. Sometimes weeks between replies but polite, if at times unhelpful.
We paid a premium to an ISP who were supposed to be highly rated. We didn't receive the purchased service. Zen had a year to sort it and didn't. They consistently advised there was no issues with their network, it was a BT problem despite Openreach proving otherwise.
We migrated that connection to 1000/115 with another ISP and amazingly we're getting good speeds... on the same fibre, same ONT and same router.
