In reply to a post by Pheasant:

That reminds me there’s a TalkTalk Business sale on their Business Full Fibre (FTTP) products until 12 July - 3 months free on a 2 year term.

So effective prices per month (ex VAT) are:
900/115 £52.46
500/75 £43.71
300/50 £34.96
200/30 £30.58
100/20 £26.21

[I signed up earlier this month]

So pretty much the same monthly price, A trade off between 3 free months or EE 4G backup.

I’d probably take the backup just because we are rural and a long haul FTTPoD and wouldn’t rule out damage to fibre. But a good price. Especially as not that long ago we were £30 for 4Mbps!
