Thanks for everyone's input.
I see a lot of people can afford it when part of a couple, and actually if I was with my ex we probably could have afforded 2 sessions a month (not that he would have agreed to pay for it but that's another story). We both earn above the average and a lot more than the minimum wage (although not big earners) and neither of us smoke/drink/gamble/waste money. It must mean that therapy/counselling is not accessible for quite a high number of working people whose priorities are housing, food, clothes and transport.
There's obviously another world out there which is hard for me to see (i.e. the people who can afford £40 a week). Maybe those who can afford it don't really get my position in the same way as I can't completely identify with people who need food banks to meet their basic needs (and there are a lot in my area, so i do accept that this is the situation for a lot of people).
The people I know with money to spend generally do it on store cards/credit cards...so they may 'spend' £160 a month on new clothes or whatever but they will be pay it off x amount over so many years.
Oh and the poster who says that self employed pay the same NI as the employed is wrong. For employed people it is 12% over £8k and for self-employed people it is 9% over £8k. (2% both employed/self employed over approx £42k) Also for self employed the amount NI is paid on is AFTER expenses such as travel, using home as business etc. have been taken off earnings.

Also EVERYONE does work they don't get paid for, many teachers probably earn the equivalent of £2 an hour when all the marking etc. has been factored in (I don't work as a teacher by the way). I've also had students loans (who hasnt, even those now working for minimum wage)
My point about the travel costs is that that its an added cost for the client on top of the fee unless the counsellor drives to their house (do they ever do this??)
I'm not saying that therapists should charge less. If the NHS was to be abolished for all health care except say emergency life/death and everyone had to pay privately care to cover routine appointments, prescriptions, treatments, non-life saving surgeries etc, surgeons, doctors, nurses etc would probably command the same salary but it would just be those who could afford that would access it, and those who couldn't would just have to go without.
