Bill Bullen, founder of the pay-as-you-go energy supplier Utilita, has offered a candid assessment of the challenges facing the UK’s energy market, highlighting policy shortcomings and proposing paths forward. Based in Eastleigh, Hampshire, Bullen has been a prominent figure in the sector since pioneering the widespread introduction of smart meters in the UK in 2008, aiming to improve energy access and affordability for low-income households.

Bullen, who built Utilita into the country’s eighth-largest energy supplier with 710,000 customers, expressed frustration with recent government energy policies, particularly the price cap on gas and electricity introduced by regulator Ofgem in 2019. While intended to protect customers from rising wholesale costs, Bullen argues the cap “caps profits” rather than prices, discouraging investment and innovation needed to tackle long-term energy affordability. He stated, “You’ve got a sector that’s needing investment, that you want innovation in — it needs to be able to attract capital.”

Utilita’s revenues have fluctuated significantly in recent years, rising to £1.2 billion in 2025 but falling from over £2 billion in 2023, reflecting market volatility exacerbated by regulatory constraints. Despite a respectable Trustpilot customer rating of 4.3 and recognition for value, the company ranked near the bottom in customer complaints according to Citizens Advice. Bullen attributes this disparity partly to demographic factors, noting that financial issues reported to Citizens Advice are often recorded as complaints against suppliers, skewing the data.

Bullen criticized prevailing government initiatives on energy efficiency, including home insulation and offshore windfarm development. While supportive of renewable energy, he contended that the expansion of offshore wind capacity has outpaced infrastructure improvements, leading to energy surpluses in some regions and higher overall costs. “We’ve built enough of them,” he said of offshore wind projects, citing inadequate transmission capacity from northern wind farms to demand centers in southern England. He added that inconsistent wind conditions necessitate backup power sources, complicating the supply mix and costs.

On the topic of carbon emissions policies, Bullen called for a more pragmatic approach, expressing discomfort with the rhetoric surrounding “net zero.” Instead, he suggested replacing it with a goal of returning emissions to 19th-century levels, roughly where UK emissions stood due to coal reductions. He advocated increasing carbon taxes while lowering other levies, viewing this as a clearer, less divisive strategy to reduce emissions.

A former engineer, Bullen launched Utilita in 2003 with an initial focus on the needs of low-income consumers, introducing smart meters that allow pay-as-you-go customers to top up energy remotely rather than using prepayment cards—a system he describes as “medieval.” He acknowledges that over a million households still lack smart meters, citing both lack of awareness and consumer apathy.

Despite his critiques, Bullen remains a committed participant in the market and is open about the need for Utilita to generate profits to attract investment. Past investors have included BP and Indian smart-meter firm Secure Meters, though both have since exited. Bullen holds a 25% stake in the company, with the remainder owned by management and an employee trust. He signaled interest in securing long-term investors such as pension funds or energy firms and indicated that a potential flotation on the London stock market could be considered should regulatory conditions improve.

As he approaches his 65th birthday, Bullen says he continues to enjoy leading the business and hopes for a regulatory environment that allows UK energy companies to succeed financially while serving consumers effectively.
