Although if there is a mortgage on the property its not so simple. And even if there isnt, before undertaking such a transfer you should take legal advice.
By the way, if you have no children, and you do not make a will, your wife will automatically inherit even if it is in your sole name, but she will have to take out a grant to your estate in order to have the property transferred into your name. If you do have children, she will not automatically inherit your full estate where you have not made a will and the property is in your sole name. So in those circumstances you should either make a will safeguarding the situation or as above, transfer the property into joint names.
