Switzerland has enjoyed the same bad reputation as Scandinavia - the fact that these countries are/were a bit more costly than neighbouring ones has gradually been exaggerated - so that "20% more costly" grew into "200% more costly".
The last years Switezland could easily compete with say London pricewise - both also had hotels and restaurants for the super rich only.
Right now you will have to care more about the value of the respective currencies:
The GBP has been dropping a lot, so most countries has become more costly for you. Fortunately for you the CHF has also fallen some - more resently - and if economy in EEurope goes really bad, there is a big risk (chance for you) that the CHF will suffer more.
One year ago you would have gotten 2,07 CHF/GBP - now unfortunately only 1,65 CHF/GBP - But any EUR-country would also have become more costly for you.
