A taste of things to come this week, with Ofwat’s announcement that it wants to regulate third party intermediaries (TPIs) in the water market by proxy, ordering water companies to deal only with those TPIs that have signed up to a code of conduct. Whether this will be an effective means of regulating their behaviour remains to be seen. Certainly Ofgem has yet to win its ongoing battle to bring order and transparency to the TPI market in energy, shelving its latest plans for a TPI code of conduct this spring pending the Competition and Markets Authority findings on the energy retail market.
