What is Ofgem and What Does It Do For Your Business?

When researching your household or business energy, you may have had cause to pause and ask, “What is Ofgem?” Below we take a look at the various responsibilities the regulatory body has, what it does to try to meet them, and how it seeks to protect small businesses.

Whether you’re a domestic energy customer, or dealing with business electricity and gas, you’ve likely heard of Ofgem.

Ofgem stands for the Office of Gas and Electricity Markets, and is the independent regulatory body for Great Britain. This means it covers consumers of domestic and non-domestic energy in England, Scotland and Wales. In Northern Ireland, the market is regulated by the Utility Regulator.

But you might not know what exactly Ofgem does. Or what rules it has created to help protect micro businesses. Below we take a look at how Ofgem works, and how it might impact your small business.

What does Ofgem do?

Ofgem’s role isn’t to create energy policy in Great Britain – that job falls to the Department for Business, Energy and Industrial Strategy (BEIS) – but rather to regulate and enforce rules and changes within the framework set out by the government. It also highlights areas that may need addressing.

What are Ofgem’s responsibilities?

At the broadest level, Ofgem’s responsibilities are to:

How does Ofgem achieve its aims?

Ofgem tries to meet its responsibilities through a combination of the following:

How does Ofgem deal with business energy?

All of the actions described above apply just as much to business electricity and gas as they do to domestic energy.

One of the most notable ways Ofgem deals with business energy is through its rules surrounding micro businesses.

For the purposes of business energy, you are classed as a micro business if you satisfy just one of the following:

This means that the vast majority of the UK’s businesses will actually fall into the category of ‘micro business’.

Ofgem dictates that suppliers must take ‘all reasonable steps’ to identify your business as a micro business. You can also supply supporting evidence to prove you are a micro business if your supplier claims you do not qualify as such. This is important, as if you are classed as a micro business you have some added protection:

In 2020, the regulatory body also carried out an investigation into the relationship between energy brokers and micro businesses. Ofgem found that a small number of unscrupulous brokerage firms were hiding fees in the contracts they had negotiated, causing some micro businesses to overpay for their energy. This has led to a rise in business energy claims being made against these brokers.

What is the Ofgem price cap?

One of the most discussed topics surrounding Ofgem is the energy price cap, officially called the Default Tariff Cap.

Originally, the Default Tariff Cap set out the maximum amount an energy supplier can charge domestic customers for a unit of energy on a default (i.e. standard variable) tariff or prepayment tariff. It is updated by Ofgem quarterly. 

However, since 1 October 2022, it is the government’s Energy Price Guarantee, and not the Default Tariff Cap, that determines the maximum per unit cost supplier’s can charge domestic customers. Nevertheless, Ofgem still sets a Default Tariff Cap, and this is used by the government to inform the Energy Price Guarantee.

When deciding the price cap, Ofgem will take into consideration a number of factors, including, perhaps most importantly, the cost of wholesale energy. It is meant to prevent energy companies from making ‘excessive profits’, while at the same time passing on ‘reasonable costs’ to customers.

Although businesses, micro or otherwise, aren’t protected by an energy price cap in the same way, any movement in the cap itself is usually a symptom of wider changes already affecting the sector.

This means, for example, if wholesale energy costs are on the rise, businesses will likely start to see the impact of this – whether through their variable tariffs, or the fixed-rate tariffs they are offered when looking to switch – before Ofgem actually gets around to increasing the price cap. 

Of course, if you run your business out of your home, and have a domestic energy contract, you may be directly affected by changes to the cap.
