In reply to Mr-Cowdrey:

In the ten years I've been going there, I've seen the exchange rate go from £1 buys 2.44CHF to £1 buys 1.38CHF
That's an increase in relitive costs of 77% from an already high base before you start to look at what inflation has done.
Switzerland is not the place to go if you are on tight a budget.
That said it's a great place, you should save up and go.
The cost of flights depends where you live but I guess you'd get from a London Airport to Geneva or Zurich for £150 return.
Train/bus transfer ticket and lift discount card cost about £130.
If you're on a budget it probably makes sense to join the Austian alpine club (uk branch) for rescue insurance and hut use discount - I'm not sure how much this costs but it's a good deal though you should bear in mind the insurance cover isn't as good as the BMC.
Not that I've done it, but biving near the huts, treating yourself to the odd meal from a hut and the odd night in a B&B to get cleaned up would probaly work out the cheapest option but you'd need to be fairly tough to stick that out for more than a couple of weeks. Also it rained a lot this year which would have been pretty miserable for biving.
