Swaptions

My googling powers are letting me down… Does anyone know what is the likely maximum time until expiration is possible on an interest rate £ swaption (e.g. 5 years) and to still be liquid. Also, how can I find out the prices. Unfortunately I’m not on Bloomberg. Any help would be much appreciated.

Way more than 5 years… Bloomberg is the way to go on prices, though.

agree with joey on both fronts…

Thanks for the help. Much appreciated.
