What are UK utility companies?

UK utility companies primarily supply essential services like electricity and gas to homes. These services are fundamental to daily life, powering appliances, heating properties, and ensuring comfort. In the energy sector, these companies are responsible for the entire journey of energy, from generation to distribution and finally, supply to the customer.

The role of energy suppliers

Energy suppliers act as the retail arm of the energy industry. They purchase electricity and gas from wholesale markets and then sell it to you at an agreed tariff. This involves managing your account, handling customer service enquiries, and issuing bills based on your energy consumption. They also play a role in installing and maintaining meters, such as facilitating a smart meter installation, and contributing to government social and environmental schemes.

Regulation by Ofgem

Ofgem, the Office of Gas and Electricity Markets, is the independent energy regulator for Great Britain. Its main objective is to protect energy consumers, especially those needing extra help, by ensuring fair treatment and promoting a cleaner, greener environment. Ofgem achieves this by issuing licences, setting and enforcing rules, monitoring competition, and providing guidance for energy companies.

Types of energy tariffs available

An energy tariff is the pricing structure for your gas or electricity, including the rate you pay for energy used and a daily standing charge. There are two main types:

• Fixed tariffs: These lock in your unit rate and standing charge for a set period, usually between 12 and 18 months, providing protection against price rises. However, you will not benefit if prices fall. Fixed tariffs may come with exit fees if you leave before the contract ends.
• Variable tariffs: Also known as standard variable tariffs (SVTs), these rates can go up or down depending on market conditions, typically changing quarterly on 1 January, 1 April, 1 July, and 1 October. Most households who have not switched recently or whose fixed deal has ended are on an SVT.

Other tariff types include dual fuel (getting both gas and electricity from the same supplier), prepayment tariffs (paying for energy before you use it), and time-of-use tariffs (offering different rates at different times of the day, which generally require a smart meter for full benefits).

Choosing an energy supplier for your home

Selecting the right energy supplier involves more than just finding the cheapest deal; it is about matching a provider to your specific needs and priorities.

Understanding your energy needs

Before comparing, assess your household's energy consumption. The average UK home uses around 2,500 kWh of electricity and 9,500 kWh of gas per year, according to Ofgem's typical domestic consumption values (TDCVs)1. Knowing your usage helps you accurately compare tariffs and understand potential costs. Your energy bill or supplier's app usually provides this information.

Comparing tariffs and deals

Independent comparison websites are invaluable tools for evaluating options. These sites allow you to compare unit rates, standing charges, contract lengths, and any exit fees. Ofgem encourages households to switch energy suppliers to keep the market competitive and drive prices down.

Evaluating customer service and reviews

While price is a major factor, good customer service is crucial. Citizens Advice ranks UK energy suppliers based on factors like complaint levels, ease of contact, bill clarity, and ease of switching. A supplier with responsive customer support can make a significant difference if issues arise.

The energy switching process

Switching energy suppliers is typically straightforward and takes up to five working days. You will need your postcode, current supplier and tariff name, and annual energy usage. Your new supplier will handle the switch with your old one. You usually have a 14-day cooling-off period, which starts when your switch request is submitted, to change your mind without penalty.

Energy supply for small businesses

Energy supply for small businesses operates differently from residential accounts, with distinct contract terms and considerations.

Key differences in business energy contracts

Unlike residential customers, small businesses often have less protection and fewer options for switching. Business energy contracts typically have fixed terms and may not be subject to the same price cap regulations as domestic tariffs. They also generally do not have the same 14-day cooling-off period for cancelling contracts.

Finding the right business tariff

Businesses should focus on tariffs that align with their operational hours and consumption patterns. Smart meters can be particularly beneficial for businesses, offering real-time data that can help manage costs and identify savings. Comparing business-specific tariffs and understanding contract terms, including any early exit fees, is essential.

Future energy solutions for businesses

The energy landscape is evolving rapidly, and businesses stand to benefit from future innovations. Access to cleaner, more abundant energy can unlock new possibilities, allowing businesses to operate more efficiently and sustainably. Fuse Energy currently supplies residential customers only but is building towards a future where it can serve businesses. Small businesses interested in future offerings can join a waitlist.

The role of smart meters and future energy

Smart meters are transforming how we understand and manage our energy consumption, paving the way for a more dynamic and abundant energy future.

Benefits of smart meters for households and businesses

Smart meters automatically send readings to your energy supplier, eliminating estimated bills and providing accurate usage data. They come with an in-home display that shows your energy use in near real-time, helping you monitor consumption and identify areas for savings. For both households and businesses, smart meters enable access to flexible tariffs, such as time-of-use rates, which can offer cheaper energy during off-peak hours.

Preparing for future energy innovations

The UK energy system is moving towards greater decentralisation and digitalisation. Smart meters are a foundational step, enabling grid stability and the integration of more renewable energy sources. Future innovations will likely include advanced grid management, further integration of electric vehicles, and home battery storage, all contributing to a more resilient and efficient energy supply.

Moving towards energy abundance

The narrative around energy has long focused on scarcity and the need to "use less." However, a future with abundant, clean energy is within reach. By rebuilding the energy system from the ground up and leveraging vertical integration, it is possible to deliver the cheapest, cleanest energy possible. This shift empowers customers with more "power to play with," allowing for greater energy use without guilt or anxiety, fundamentally transforming our relationship with energy.

Frequently asked questions about UK utility companies

What is the energy price cap?

The Energy Price Cap, set by Ofgem, limits the maximum amount energy suppliers can charge for each unit of gas and electricity on standard variable and default tariffs. It also sets a maximum daily standing charge. The cap is reviewed quarterly to reflect changes in wholesale energy prices and other industry costs. It is important to remember that the cap limits unit rates, not your total bill; the more energy you use, the more you pay.

What happens if my energy supplier goes bust?

If your energy supplier goes bust, your energy supply will not be interrupted. Ofgem has a "Supplier of Last Resort" process, where they appoint a new supplier to take over your account, usually within a few days. Any credit you had with your old supplier is protected and will be transferred to your new account. You will typically be placed on a Standard Variable Tariff with the new supplier, but you are then free to switch to a different tariff or supplier without exit fees.

Managing your energy bills should be clear and easy to understand. Fuse Energy focuses on straightforward pricing, so you can see exactly what you are paying without unnecessary complexity. If you have a smart meter, you can view detailed usage data through the app or website, helping you understand how you can lower your bills. If you do not have a smart meter, Fuse Energy can upgrade your non-smart meter, completely for free. This can make it easier to track spending and make informed decisions about your energy use.
