Had a BT salesman in over the weekend and he told me that Business traffic gets priority over domestic traffic, no matter what time of day or week it is. 24/7 business traffic gets priority. Is this true?

I'm with Zen FTTC 80/20 home. I play Counter Strike and was wondering if it would be better. Connection speed is super important for CS.

I think you'll find latency is important, not speed.

Yes, I worded that badly.

Unlikely to make any difference, a sales droid just chasing a sale.
What is more likely to have an impact is
1. State of interleaving on the connection
2. Your location in the UK
3. How the ISP has set up its network
Traffic priority (which is higher anyway on the 80/20 products) will be referring to bandwidth rather than any priority on latency.

on the old ADSL products they used to refer to a contention ration all the time, wonder if he was hinting at that, business lines used to have a lower contention ration over residential.
whatever - I call it bull and was just chasing a sale.

So there is a fair chance you are on Zen's own network and are not connected via any BT system anyway.
Which exchange are you on ?

Sounds like BS 
A BT connection will most likely be full speeds 24/7 regardless, my experience is just that.

I'm on the Fleetwood exchange.

Yes it's true, but only at some points in the network. Other ISP's business products using BT backhaul may or may not have this option, some offer it as a paid add-on. Prioritisation by its nature will affect bandwidth and latency, since they are related, but only where there is congestion in the first instance, and that means the benefit is rarely seen in practice.

The only time I notice a slight dip in connection quality is when the football is on during Saturday and Sunday afternoon since every man and his dog is streaming it. I'm not having a dig at those people. Since I have a job/wife/child it's my best time to play, so it is interesting for me, if it is actually true.

I do not think prioritisation would give you a perfect connection where congestion exists. Perhaps I am wrong.
E.g. When I have experienced past pro-longed congestion, the speeds have plummeted from 80Mbps to 2Mbps during evenings for months running until the issue was resolved... Here I feel the congestion is so significant you would be almost certainly not see full speeds as a business user. Could be wrong.

I have a Zen business FTTC connection that normally runs at 74Mbps down and in past in times of heavy congestion (I am told due to a congested SVLAN) the connection was running in low single digits down at best. i.e. It didnt feel like being business grade was any advantage in this scenario.

BT Business do "guarantee" a minimum speed for their users based on the normal sync if there is major congestion. It is significantly lower - maybe around 20-25% from memory so about 15-20Mbps for my line. I have never experienced it - that I know of and it is only a bandwidth guarantee not latency. If congestion ever got to that stage that latency would go through the roof and gamers would just give up!

whatever - I call it bull and was just chasing a sale. Some isp's who had their own LLU network , only claimed the contention ratio's advertised were within their network, anything outside that could be higher or lower, as they had no control of another companies network, Ukonline advertised 20:1 and 33:1 ratio's within their network, which was originally owned by easynet and later purchased by Sky, but uko customers were routed differently and appeared to get priority over sky customers , as sometimes sky would suffer issues that uko customers didn't see So it wasn't all bs
But today things are a lot different

Interesting, yes on Sky Fibre many many years ago, when I had congestion I was hitting 2Mbps in the evenings and the upload even went to rubbish. I remember ukonline customers who had either at the time been auto migrated to sky or were in progress of being migrated (not even totally sure my memory fails me), who were business customers, also had congestion.
This was a Sky Fibre 80/20 Service, I was either trailing it or it was just introduced. Feel I was trailing it, and not enjoying it.
Also had an ADSL line at the time which was congested too. Different address, same exchange.
With congestion in 2012:

On openreach I think the assured rate is higher for priority services. On BT wholesale side there is also a priority system, but since congestion is not a normal occurrence (unlike VM), then in practice there is no difference.

Every single VM I have ever used has had congestion showing on a single threaded download. It is shocking to me that they get away with it.
