FAQ
What is an Ofgem-licensed electricity company?
An Ofgem-licensed electricity company is authorised to undertake a regulated activity in Great Britain’s electricity market. Depending on its licence, the company may generate electricity, supply customers, operate distribution or transmission infrastructure, or manage an electricity interconnector. A licence does not necessarily mean the company sells electricity directly to customers.
Compare today's live rates
How many electricity companies are listed here?
This directory lists 1,036 Ofgem-licensed electricity companies across eight licence categories. These include 836 generators, 103 domestic or non-domestic suppliers, 41 distribution companies, 30 transmission companies, 25 interconnector companies and one smart meter communications licensee.
Are all electricity companies energy suppliers?
No. Most electricity companies in this directory do not sell electricity directly to customers. The list also includes generators, transmission companies, distribution network operators, independent distribution network operators, interconnector operators and the smart meter communications licensee. Electricity suppliers are the companies that sell electricity directly to homes or businesses.
Which electricity companies serve business customers?
Electricity companies holding domestic and non-domestic or non-domestic-only supply licences may serve businesses. However, having a licence does not guarantee that a company is currently accepting every type of customer. Businesses should check the supplier’s consumption requirements, geographical coverage, available tariffs, credit criteria and contract terms before applying.
What licences can an electricity company hold?
An electricity company may hold a licence covering generation, supply, transmission, offshore transmission or interconnection. Ofgem also regulates electricity distribution operators and the smart meter communications licensee. The licence required depends on the company’s role and the regulated activities it undertakes within the electricity market.
How can I verify an electricity company?
Check the company’s exact legal name against Ofgem’s electricity licensee list or electronic public register. You can then use Companies House to confirm its registered company number, address, incorporation date and current status. Checking the legal entity is important because a supplier’s trading name may differ from the company holding the licence.
Can one electricity company hold multiple licences?
Yes. An electricity company may hold multiple licences when it performs more than one regulated activity. For example, a business could hold both generation and supply licences. Large energy groups may also use several related legal entities, with each company holding a different licence for a particular project, network or market activity.
Can businesses switch electricity company easily?
Businesses can switch electricity company, but they usually need to wait until their existing contract permits it. Business energy contracts can last for up to five years, and most suppliers will not allow an early switch. Businesses should check their contract end date, notice period, termination charges and renewal terms before arranging a new supply contract
Why compare electricity companies before switching?
Electricity companies can offer different unit rates, standing charges, contract lengths, renewable options, payment terms and customer service standards. Businesses should compare the estimated total annual cost rather than focusing only on the advertised unit rate. Broker fees, pass-through charges, exit fees and automatic renewal terms should also be examined before signing.
What if my electricity company closes?
Your electricity supply should continue if your supplier stops trading. Ofgem can appoint another licensed supplier through its Supplier of Last Resort process. Businesses should take a meter reading, retain copies of recent bills and wait for the replacement supplier to make contact before switching elsewhere. Business credit balances are not protected in the same way as domestic balances.
