i have got to change over a w plan system. If it was just changing to a Y plan, is it just a case of ptting in the new mid position valve and running a hot water off? Or, would you recommend changing it to an S plan?

I always go s plan. Y plan is for 1980's fit a balancing locksheild type gate valve on bottom of cylinder. (Locksheild to prevent DIY helpers)
just a gate valve on the cylinder return.
