Thanks. Yes, one deck cut off is 17% (i.e. 83% penetration). It would be very instructive to compare results for those three levels of pen - 67%, 75%, and 83% - and for differing rules.

Yes, I did mention the insurance change in one casino chain, but it came along with a change to 8 decks, which potentially puts a slight dent in the benefit. (I'm not sure of the penetration in the 8-deck games.)
I guess it's everything in combination that may yield a poor game, with penetration being the key factor than can overcome any worries about the rules.
All the UK-specific rules -
- ENHC.
- No Insurance apart form even money (in most places).
- No surrender.
- must have an impact. (Though at least it is no longer D9.)

Yes, I know BS is different for ENHC. The point is that the difference in HE for a counter is not the fixed 0.11% that it is for a flat bettor. Earlier, you seemed to be implying that once this 0.11% has been overcome by removing a few extra small cards from the deck, and we reach, say, a 2% advantage, ENHC has no more drawbacks than the US game.
But the advantage of a high TC comes from the ability split and double (as well as receive more BJs). The fact that we can't do these things quite as often under the modified BS of ENHC rules means that for
every increment in the TC and corresponding rise in our bet size, we do not get quite as much benefit as under US rules.
There was a thread some time ago in which it was suggested that the impact on a counter was about 0.4%
http://www.blackjackinfo.com/bb/showthread.php?t=11431 (presumably that relates to the average bet).
Obviously the lack of insurance and surrender aren't uniquely British, so I imagine there is more existing information quantifying the impact of these.
As with ENHC, I think no surrender hits the counter harder than it does the BS player. In high counts, with big bets out, more hands will be candidates for surrender (due to reaching the indices for additional surrenders, and perhaps also due to a higher frequency of BS surrender hands like 16v10 appearing at those counts).
And surrender has an impact on variance as well as EV, so will have a double impact on SCORE.
Insurance speaks for itself in terms of EV - BS players never take it, but it's top of the list of the I18. (I'm not sure if it has any significant impact on variance if we just use the normal insurance index.)

The £2 minimum must certainly be a help. In London it is mostly either £10 or £5 (with £3 available at some places during slow times of the day).
1-20 is about what I guesstimated the absolute minimum spread would have to be, with as suspicion that it might have to be rather higher to get any significant return. A lot comes down to the definitions of words like 'playable' and 'worthwhile'.
And if the unit size is also the table minimum, that would seem to indicate that a replinishable bankroll is very important, since you can't resize your bets downwards after a significant run of losses. (Backcounting and only playing at higher TCs might be an alternative, but that doesn't really work well with the limited number of tables and casinos available.)

To elaborate on the bankroll question - The OP was asking how much to take to the casino (i.e. the session bankroll). The thing you want to avoid is the possibility of running out of money while at the table. If your top bet is £40, you could conceivably find that BS calls upon you to make multiple splits and doubles, risking £80, £120, ... maybe even £320 on a single round. Or a sustained high count might mean several rounds with your top bet out, all of which you can quite easily lose; again, you do not want to be forced to leave the table because you have run out of cash while the high count persists.
But the much more important question, which Ming alluded to, is not the session bankroll but the overall bankroll. Or to put it another way, how much can you afford to lose? (It should be measured in thousands.)
If you are a student, with limited funds, then I really think you should stay clear of the casinos for now, apart perhaps from the occasional bit of low-stakes fun. The very big, very real risks are just not worth the meagre potential rewards.
