Based on te BT estimate - they are improving, go for 40/10 and then with an unlocked modem see what it will achieve. If you like the numbers you see, then regrade - yes it might lengthen the contract by a week or two, but is that an issue?

an estimated WBC FTTC Broadband where consumers have received downstream line speed of 51.7Mbps and upstream line speed of 13.2Mbps.

Snap - again! I'm mildly curious to know the parameters and model they use.

Just checked the web portal but there's no sign of any option to upgrade the business product yet; they're busy pushing paper-free billing.

My estimate is 61mbs down and 20 up, Yet my attainable rate is now 95mb and 34 mb, this is on a full cab too.

If it is a new install or migration to BT then you only have 2 options according to their website
1/ If you want the cheaper £18 pm with 40Gb download limit you get 40\20
2/ The £26 option with Unlimited downloads comes with 80\20

You only get the option to upgrade if you already have BT Infinity installed.

for me the checker says;

Our test also indicates that your line currently supports a fibre technology with an estimated WBC FTTC Broadband where consumers have received downstream line speed of 40.2Mbps and upstream line speed of 6.1Mbps.

Should i go for infinity 80/20 or the 40/10?

EDIT: Currently with Be and they say i should be getting 7mb with their LLU, but i'm getting around 15mb.

I'd say go for 40/10 - you're unlikely to see much above 40 even if the checker is being cautious. At the end of the day are you going to see a difference between 40 and 50 that you can make a real use of?

didn't think about that, i was wanting the unlimited option so i guess the 80/20 it is!

thanks!
