TWO more Proserpine business owners have come forward to express frustration about Ergon Energy's lockout rule.

Pacman and Sons owner Chris Pilgrim was first to speak out, unhappy with having to remain with QEnergy, which is the only private retailer in Proserpine for small business.

Ergon is bound by a State Government "non-reversion” policy that prevents premises from returning to Ergon after leaving.

Archer's Soft Drinks Proserpine part-owner Michael Horsford said he switched to QEnergy because it promised cheap electricity.

"I was never informed, Ergon only told me me later that I couldn't go back, so I'm pretty disappointed with it,” he said

Mr Horsford said he had issues with the company which he took to the Electricity Ombudsman.

Organic House of Hair and Beauty owner Cathy Thomson said the previous owners of her business switched to QEnergy.

Ms Thomson immediately tried to connect to Ergon, only to be informed she was not eligible to return.

"My preference would be Ergon because with no other competition, my concern is they can set their rate at whatever they want,” she said.

Ergon Energy spokesperson Jamie Rule directed the Whitsunday Coast Guardian to the State Government for comment.

A representative for the Energy minister said the Queensland Government was considering the implications of keeping or scrapping the policy and LNP energy spokesman Michael Hart said the policy needed to be "looked at”.

Comment is being sought from QEnergy.
