Who are Ofgem?

What is Ofgem?

Ofgem stands for the Office of Gas and Electricity Markets. It is the independent regulator for the energy industry in Great Britain. Just as Ofcom regulates the communications sector and Ofwat oversees water infrastructure, Ofgem is responsible for making sure the energy market works fairly for consumers.

As a non-ministerial government department, Ofgem operates independently from both the government and the energy companies it regulates. Its main job is to protect consumers, both right now and in the future. It does this by setting rules that energy suppliers must follow, ensuring there is fair competition in the market, and taking action when companies break the rules.

For the average household, Ofgem is most visible when it announces the quarterly energy price cap. But its work goes much further than setting prices. The regulator also manages environmental schemes, enforces customer service standards, and is currently working to prepare the national energy grid for a zero-carbon future.

How Ofgem sets the energy price cap

The energy price cap is Ofgem's most well-known mechanism. Introduced to stop suppliers from overcharging loyal customers on default tariffs, the cap limits the maximum amount a supplier can charge for each unit of gas and electricity you use. It also caps the daily standing charge. Ofgem updates these figures every three months to reflect changes in the wholesale cost of energy.

On 1 July 2026, the price cap increased by about 13%. For the July to September period, average unit rates are capped at roughly 26.11p per kWh for electricity and 7.33p per kWh for gas. Standing charges are capped at around 57.19p a day for electricity and 29.04p a day for gas, though these exact figures vary depending on where you live in the country.

When Ofgem announces the new price cap, it usually provides a headline figure for a 'typical' household paying by Direct Debit. From July 2026, this figure is £1,663 a year. This number is based on Ofgem's Typical Domestic Consumption Values, which are estimates of how much energy a normal home uses. On 1 July 2026, Ofgem updated these estimates to reflect that households are now using around 7% less electricity and 17% less gas than they used to. If Ofgem had stuck to its older, higher usage estimates, the July 2026 cap would be reported as £1,862 a year.

It is worth noting that the price cap only applies to standard variable tariffs. It does not apply to fixed-rate tariffs. This means households face a choice: stay on a variable tariff and let Ofgem's cap dictate your rates every three months, or lock in a fixed tariff to guarantee your unit rates for a year or more. Around 21 million households are currently on standard variable tariffs.

Consumer protections and complaints

Ofgem sets strict rules that energy suppliers must follow regarding how they treat their customers. These rules cover everything from how clear your bill needs to be, to how suppliers must support vulnerable households. When companies break these rules, Ofgem has the power to step in and issue severe financial penalties.

However, Ofgem does not handle individual customer complaints. If you have a problem with your energy bill, a faulty meter, or poor customer service, you cannot go straight to the regulator. Instead, there is a set process you must follow to get the issue resolved.

While Ofgem does not deal with your personal complaint, it monitors the types of complaints being made. If it notices that a supplier is consistently failing its customers, it will launch an investigation. Financial penalties are paid to the Treasury. Separately, Ofgem may require a company to make a voluntary redress payment into the Energy Redress Scheme. This fund distributes the penalty money to charities and community groups that help vulnerable people at risk from cold homes. For example, on 2 June 2026, Ofgem opened a £30,000,000 funding round using money collected from supplier fines.

Ofgem's protective reach is also expanding. As of 27 January 2026, Ofgem officially became the regulator for heat networks, which are communal heating systems that serve multiple homes from a central source. This change brought new rules around fair pricing and transparent billing to households that were previously completely unregulated.^[1]

Managing government energy schemes

As well as regulating the commercial market, Ofgem acts as the administrator for several large government schemes. These programmes are designed to improve the energy efficiency of UK homes, lower carbon emissions, and help low-income households afford their energy bills.

Because Ofgem already has the systems in place to monitor energy suppliers and installers, the government tasks it with running these initiatives. This involves checking eligibility, ensuring suppliers meet their legal targets, and distributing funds fairly.

While Ofgem currently manages these schemes, it does not set the policy behind them. The government decides who qualifies and how much money is available, and Ofgem simply executes those rules on the ground.

How is Ofgem governed and funded?

A common misconception is that Ofgem is funded directly by taxpayers. In reality, the vast majority of its income comes from licensing fees. Ofgem’s regulation work is funded through annual licence fees paid by some licensed energy network companies. It also receives funding from government departments for specific projects. This system ensures that the cost of regulating the market is borne by the industry itself, rather than coming out of general taxation.^[1]

Ofgem is governed by its board, the Gas and Electricity Markets Authority (GEMA). GEMA is Ofgem’s decision-making authority, rather than a separate body that regulates it. It is made up of experts from finance, science, social policy, and the energy industry. GEMA determines the long-term strategy, sets the policy priorities, and decides on the enforcement measures that Ofgem carries out.

The way Ofgem operates is currently undergoing a major shift. In April 2026, the Department for Energy Security and Net Zero published its final report on reforming Ofgem. It proposes a more outcomes-focused approach, but many changes to Ofgem’s duties and enforcement powers require legislation before they can take effect.

Preparing the energy grid for the future

Looking ahead, Ofgem has a legal duty to help the government meet its net zero carbon emissions targets. This means it must ensure the energy market can handle a massive shift away from fossil fuels and towards renewable electricity. This is a difficult balancing act: Ofgem must encourage the industry to invest billions in new infrastructure, while ensuring those costs do not fall unfairly on the consumer.

A major part of this work involves reforming how new projects connect to the national grid. Currently, there is a long queue of new wind farms, solar sites, and large-scale demand customers like data centres waiting to be plugged in. Ofgem is actively changing the connection rules to speed up this queue and maintain the security of the system.

It is also refining the rules for new technologies. For example, in July 2026, Ofgem approved changes to the terms and conditions for NESO’s Dynamic Response Services. These include a pre-approved baseline requirement where services are stacked, helping to avoid providers being paid twice for the same capability.
