"Over 2 years" is the average monthly cost across 24 months once any intro offer ends and the rises written into the contract apply. Some advertised prices are intro offers that end after a set number of months. From Zzoomm's live deals, updated every day.
Getting a fair result
Run the test on a laptop plugged into the router with a cable. Over wifi you'll often see less than the line is giving you.
None of Zzoomm's 17 deals has a price rise written into the contract.
If it’s still slow
Zzoomm hasn't signed Ofcom's voluntary broadband speed code, so there's no set 30-day right to leave over slow speeds. Report it to Zzoomm first. If it isn't sorted after six weeks, you can take it to the free dispute scheme Zzoomm belongs to.
Zzoomm runs its own network, so a fault on the line is Zzoomm's own to fix. Source
Questions
Zzoomm speed questions
What speed should I get on Zzoomm?
Zzoomm sells 9 speeds today, from 150 Mbps to 2.3 Gbps, all of them full fibre, so the fibre runs all the way into your home. Check which package you're on, then compare it with a wired test. The table on this page shows the speed each package is sold at.
Why is my Zzoomm broadband slow?
Run the test on a laptop plugged into the router with a cable. Over wifi you'll often see less than the line is giving you. If the wired result is fine, the line is doing its job and the slowdown is in your home: the router's position, other devices or an old wifi standard. If the wired result is low too, switch the router off at the wall for 30 seconds, test again, then report it.
What can I do if Zzoomm can't fix my speed?
