The only WC that complies with specific regualtions is the main WC on the entrance floor of the property. This must comply with part M of the building regualtions. 450mm is the minimum here, but if it is for another bathroom or en-suite there are no minimums.
Go to the planning portal, you can down load the building regulations - its Approved Document M you are looking for.
