What Do I Need To Do When Switching Energy Supplier?

What do I need to do when switching energy supplier?

Switching energy supplier is a common step for UK businesses looking to control costs and improve their energy arrangements. Understanding the process can help ensure the transition is smooth and avoids any disruption.

While the switching process itself is usually straightforward, there are several important steps businesses should take to make sure everything runs efficiently.


1. Check your current contract

The first step before switching supplier is to review your existing energy contract. Most business energy contracts are fixed-term agreements, and leaving before the end date may trigger termination fees or penalties.

Businesses should check the contract end date, notice period, and any specific termination clauses. Many contracts require notice to be given before the end of the agreement. If notice is not provided within the required timeframe, the contract may automatically roll over or move onto higher out-of-contract rates.

Understanding these details early will help you avoid unnecessary costs and ensure you can switch at the correct time.


2. Compare suppliers and contract options

Once you know when you are able to switch, the next step is to review available options in the market. Different suppliers offer a variety of contract structures and pricing models, and it’s important to choose one that suits your business’s needs.

When comparing suppliers, businesses should look beyond the headline price and consider other factors such as reliability, billing arrangements, customer support, and flexibility. For organisations with multiple sites, it may also be useful to check whether suppliers can align billing dates or provide consolidated invoices.

While this process can be time-consuming for many businesses, we offer a free market review, where we obtain quotes on behalf of your business and assist with comparing the available options.


3. Confirm meter details and site information

Before a switch can take place, suppliers will typically need accurate information about the site and energy meters. This includes the MPAN (for electricity) or MPRN (for gas), the business address, and details of current consumption.

Providing accurate information helps suppliers produce more reliable quotations and ensures the switching process is completed correctly. If a business has multiple locations, it may also be worth reviewing whether all sites should be included in the same contract portfolio.


4. Agree the contract and switching date

Once a supplier has been selected, the next step is to formally agree the new contract. The supplier will confirm the start date for the new supply, which typically begins immediately after the current contract ends.

In most cases, the switching process happens automatically behind the scenes. The new supplier will coordinate with industry systems and the existing supplier to transfer the supply on the agreed date.

Importantly, the physical supply of electricity or gas does not change when you switch supplier. The same infrastructure and network operators continue to deliver energy to the site, meaning there is no interruption to supply.


5. Submit final meter readings

Around the time the new contract begins, businesses may be asked to provide a meter reading. This allows the previous supplier to produce an accurate final bill and ensures the new supplier begins billing from the correct usage level.

Keeping a record of these readings can help resolve any potential billing queries later on.


Plan ahead for future renewals

Switching supplier is also a good opportunity for businesses to review their longer-term energy strategy. Monitoring contract end dates and market conditions can help businesses avoid expensive out-of-contract rates and ensure they continue to secure competitive pricing in the future.

With consumer spending declining and OFGEM raising their price cap, you would be forgiven for seeing February as a month where negative news was at the forefront, but in the energy markets, this was not the case.

In a year that began with falling energy prices, there were recurring catalysts that led to prices climbing steadily higher. Geopolitical uncertainty and the perennial threat of escalating conflicts meant fear would maintain a constant presence in the wholesale markets. We will look back at the key energy stories from 2024, and how the energy markets are likely to shape up in 2025. Quarter 1  The year began with cautious optimism as the UK’s gas reserve levels were healthy and prices for the Summer’24 season were in freefall. In February, prices pulled back to their lowest levels since 2021, and for the first time in a while, we identified that there was greater potential for upside risk than for further downward price movement: “ there now (exists) an asymmetrical element of risk should the market encounter a supply-side problem of significance. ” During February we had advised customers on flexible contracts that this was an ideal time for making purchases. March would see prices begin to ascend again as international conflict would create problems with LNG imports, and we would highlight the geopolitical risks as an area for concern moving forwards: “ fears remain and there are potential negative catalysts that could lead to prices rising further, with the main factors to watch out for being based on geopolitical unrest. “ For a business that purchases their energy in advance, this quarter was the optimal time for purchasing during 2024. In February, electricity prices for Winter’25 were down to 7.75p/Kwh, and as low as 6.05p/Kwh for Summer’25. Winter’25 ended the year with prices above 11.1p/Kwh, with Summer’25 prices exceeding 9p/Kwh. For a company that uses 500,000Kwh of electricity per month, the difference between buying at the February low point compared to today’s prices would represent a yearly saving of over £200,000.
