Who Are Ofgem and What Do They Do?


In the intricate tapestry of the UK’s energy sector, Ofgem plays a pivotal role. Officially known as the Office of Gas and Electricity Markets, Ofgem is the regulator for the electricity and downstream natural gas markets in Great Britain. This blog aims to demystify Ofgem, elucidating its functions, responsibilities, and the impact it has on both consumers and the energy industry.

What is Ofgem?

Established in 2000, Ofgem emerged from the merger of the Office of Electricity Regulation (OFFER) and the Office of Gas Supply (Ofgas). This organisation is a non-ministerial government department, functioning independently but accountable to Parliament and the Department for Business, Energy and Industrial Strategy (BEIS).

Key roles of Ofgem

1. Protecting Consumers

One of Ofgem’s primary roles is to protect consumers, particularly the vulnerable and those in fuel poverty. This involves ensuring that consumers pay fair prices for their energy and receive reliable and sustainable energy supplies. Ofgem achieves this by regulating tariffs and monitoring the market to prevent unfair practices.

2. Regulation and Competition

Ofgem is responsible for supervising and promoting competition in the energy market. By regulating monopolies in electricity and gas networks, Ofgem ensures that these companies do not overcharge customers and that their services are efficient and sustainable. This also involves approving price controls and regulating how much money network companies can earn.

3. Environmental Responsibilities

Aligned with the UK’s commitment to reducing carbon emissions, Ofgem plays a significant role in overseeing environmental programmes. These include initiatives like the Renewable Heat Incentive and the administration of government schemes designed to promote renewable energy sources.

4. Ensuring Industry Stability

Ofgem’s role in ensuring the stability and safety of the energy industry cannot be overstated. The organisation oversees the delivery of secure energy supplies, even amidst market shocks or supplier failures. Ofgem has mechanisms in place to protect consumers in case their energy supplier goes out of business.

5. Encouraging Innovation

In the rapidly evolving energy sector, Ofgem encourages innovation to improve service quality and efficiency. Through various programmes and incentives, Ofgem supports the development of new technologies and smarter energy systems that benefit consumers and reduce environmental impact.

Impact on consumers

The actions of Ofgem directly impact UK energy consumers. Through its regulatory measures, Ofgem ensures that consumers are not overcharged and that their energy supply is consistent and of high quality. Its environmental initiatives also aim to create a more sustainable future, which is a collective benefit.

Ofgem’s influence on consumers extends beyond general market regulation. A key area where this impact is most visible is in the implementation and adjustment of the energy price cap. This aspect of Ofgem’s responsibilities has direct and significant implications for household energy bills across the UK.

What is the Energy Price Cap?

The energy price cap is a limit set by Ofgem on the maximum amount energy suppliers can charge customers per unit of gas and electricity. It’s important to clarify that this cap is not a limit on total bills, which can vary depending on the amount of energy used. The cap is designed to ensure that consumers on default tariffs, including standard variable tariffs, do not pay excessively for their energy.

How Does the Price Cap Work?

The cap is reviewed and adjusted by Ofgem twice a year, reflecting changes in the wholesale cost of energy. This means the cap can go up or down, depending on the market. The purpose of these regular reviews is to balance fair prices for consumers while ensuring the viability of energy suppliers.

When wholesale energy prices rise, the cap may increase, allowing suppliers to cover their increased costs. Conversely, when wholesale costs fall, the cap is lowered, passing on savings to the consumer. This mechanism is crucial in protecting consumers from sudden spikes in energy prices, especially in volatile markets.

Impact of the Price Cap on Consumers

For consumers, the energy price cap offers a layer of financial protection. Those on default tariffs, who might not actively switch suppliers or tariffs, are shielded from overpaying for their energy. The cap also indirectly encourages competition in the energy market, as suppliers are motivated to offer more competitive prices below the cap to attract and retain customers.

However, consumers need to understand that the energy price cap is not a fixed price guarantee. As the cap reflects market conditions, energy bills can still fluctuate, sometimes significantly, when the cap is adjusted. Therefore, consumers are encouraged to remain informed about these changes and consider energy efficiency measures or explore fixed-rate tariffs for more predictable billing.
