Tomorrow I might order G.fast with Zen Internet as Zen say the total cost below:
New line installation £70.80
New G.fast activated fee £55.00
New G.fast service 160/30 £49.99
Total cost one off payment £175.79 then 11 monthly payments of £49.99 on a 12 months contract.
Openreach email communicate with me below:
1st email:
I’ve had one of our technical experts take a look at why the 2 premises below are being quoted different speeds, he’s confirmed that this is due to discrepancies being identified on one of the lines that would need to be resolved to enhance the speed. In this instance (mine) would be offered a managed install (engineering visit) to optimise the line and fix any wiring issues, whereas (next 2 doors) could opt for a self-install. The estimated speeds are based on physical measurements taken from our line test systems.
2nd email:
An engineer managed install will certainly help you achieve the best possible speed, however I’m unable to provide a guarantee as to what that would be. Given the estimated speeds from the line tests, you would hope something very close to 300mb would be achievable.
3rd email:
Unfortunately an engineer visit can only be arranged once we have received an order. There’s a number of ISP’s who can offer the GFAST service, however they would all be in the same position.
4th email:
The ISP’s can and do set different minimum thresholds, you would therefore need to discuss this point directly with them.
Anyway I spoken to Zen Internet as they asked the provisioning team of everything what openreach and I was communicate about G.fast and Zen say that Engineer is only come to my property to installed new line socket as per of my request and put in the same hallway where the feed are coming in from outside as it will be in your master socket (where your current FTTC on it) and added a second master socket for G.fast and switched the line on. Zen say engineer are not responsible for any optimise the line and fix any wiring issues such as very close to 300mb would be achievable nor set different minimum thresholds. U will order 160/30 as our test system say your line will support 198Meg down and 29Meg up but these could anything from 114Meg to 152Meg for your line. We held no responsible for not getting 300Meg or more as your line length are much further away from the exchange to the cabinet.
But, Zen Internet warned me 10 days cooling period is only start from the day of your order not the day of your G.fast activated so u can't cancelled the order once it was activated as it will be more than 10 working days for the new line and G.fast possible within 2 weeks.
here is layout of where the g.fast cable route (sorry for my poor layout drawing) go to:
