Where can I get suitable training courses?

As regards training courses, there is a global programme administered centrally within PMI HQ (in the US), for consistency. This is titled "PMI Registered Education Provider Program" (REP).

The R.E.P. Program is designed to enhance the ongoing professional development of PMI Members, Project Management Professionals (PMPs), and other project management stakeholders through participation in various learning experiences and activities related to the field of project management. Examples of Registered Education Providers may include PMI Chapters and Specific Interest Groups (SIGs), consultants, schools, corporate training centers, government agencies, professional associations, and any other providers of education related to project management.

There are UK providers registered to provide the training, but the UK Chapter itself does not have a local UK based certification.
