Huddersfields electricity retailer, Goodmans Electrical, is making changes to its website to help customers avoid overcharged bills.
The website, which has been taken down, has replaced the “Free” section with an “Ask a Question” section.
The “Ask” section, which contains answers to questions people have about their electricity bills, now asks people to explain why they have charged their electricity costs more than their previous billing cycle.
Goodmans said it would “continue to work hard to reduce overcharging”.
It added that it has already worked with customers to offer a “reduced overcharge” discount.
The move comes after Goodmans said last week it would raise the price of its “regular” electric bills from £12.90 a month to £18.70 a month, which is less than half the £20 a month the retailer charged customers.
The retailer’s “normal” price is £16.60 a month.
Huddersfell has been a leading electric retailer in the UK since 2006, when it was renamed Goodmans.
The company, which also owns the former Huddington Electric and is the oldest electric utility in England and Wales, employs around 20,000 people across the UK and employs nearly 2,500 people at its two Huddeston-based sites.
It was founded in 1851, making it one of the oldest public utilities in the country.
The Huddeston site, which opened in 1912, is located in the heart of Huddons most affluent area, which includes Huddfield, Huddings Green and Huddham.
