The Energy Advice Line has spearheaded a campaign for the energy regulator Ofgem to ban the practice of cold calling because it placed undue pressure on consumers to agree to energy deals that were not necessarily the cheapest available.
"Although this case related to automated calls, it highlights the lengths that some companies go to to pressure consumers to buy their product or service," Mr Morgan said.
"We firmly believe that truly independent and reputable price comparison and switching services should not resort to unsolicited telephone calls. In awarding the record fine, the Information Commissioner rightly described nuisance calls as a 'modern pest'.
"Chooseing an energy supplier is a cruical decision because a bad choice can cost a household or business hundreds of pounds, or even more in the case of large organisations.
"Consumers need time to consider their decision and not be placed under pressure during an unsolicited telephone call."
Mr Morgan said he was aware of cases where consumers had been called, repeatedly, in once case while they were attending a funeral, by unscrupulous energy 'brokers' using heavy pressure sales techniques to force them to agree to an energy deal.
He said in many cases these cellars were not independent, despite their claims to the contrary, and were often calling on behalf of a single energy supplier and therefore not necessarily offering the cheapest deals.
"We would like Ofgem or the Information Commissioner to investigate the practice of cold calling by energy suppliers and the third parties they sometimes engage to do it," Mr Morgan said.
"Consumers need to take control of their energy supplies and shop around to find them the best deals, and switch accordingly.
"Truly independent and reputable services like the Energy Advice Line would never engage in cold calling because we don't need to. Consumers trust us to help them shop around and we never pressurise them to make a decision.
"Unfortunately not all suppliers or price comparison services take the same view and consumers need to be protected from them."
The Energy Advice Line is one of the UK's leading price comparison and switching services for business and domestic energy customers. It is also an advocate for energy market reform and has campaigned for a better deal for energy users, including calling for a ban on cold calling and changes to regulations to make it easier for all consumers to switch suppliers.
The service is completely independent and free. Consumers can quickly and simply search the market for the best available energy deals from an extensive panel of small and large energy suppliers. The service also offers a free advice line for business energy customers.
