The extreme market circumstances that are typical in the energy sector are confusing.  Making sense of all the many components is a difficult, time-consuming task that may be quite frustrating. For any organisation, attempting to navigate the energy market without expert assistance may prove to be a costly choice. Any organisation that is unfamiliar with the inner workings of the energy market is recommended to consult an energy specialist. To navigate this complicated market successfully, knowledge and timing are crucial. RES can meet all of your energy demands by offering guidance from professionals who know the market.

A Letter of Authority, or ‘LOA’ as you may hear from time to time, gives brokers like ourselves the permission to obtain meter & supply data from your current supplier/s. Our LOA covers electricity and gas, if you have both! Essentially it is you giving consent to your current supplier/s to provide us with the necessary information needed to tender your utilities supply. It can also be quite useful when you’re strapped for time or just struggle to find a copy of a recent bill!

You can either contact your current supplier, or you can estimate your consumption by calculating this from the consumption shown on your last invoice. Alternatively, we can find out this information using a Letter of Authority.

For many energy suppliers you can agree a business energy contract anything between 3 and 5 years ahead of today. However, the majority of suppliers offer a renewal window of 12 months prior to your current contract end date.  

What we find is that most businesses only review the contract renewal 4-6 months ahead of their current contract end date, but that doesn’t mean you need to follow that trend! 

Some businesses contract for their energy more than a year in advance and others leave it until the last minute. There are advantages and disadvantages to any approach, but we will always provide you with comprehensive recommendations, with you and your businesses best interests in mind. 

Something to remember is that you can arrange a contract today to follow on from your current contract and it will not take effect until your existing contract has ended. This means you cannot just jump to another business energy contract until your current deal.

As standard in the industry, business energy suppliers do not operate a policy of cooling off periods when agreeing contracts with their customers.  This is because suppliers forecast and buy the energy based on the business’ consumption. If they were to offer a cooling off period, the argument goes that they would need to price the potential risk of non-recovery into the contract and as a result levy higher charge. 

Make sure you check the tariffs available from us and compare them to your renewal offer. 99% of the time, our tariffs will be far more competitive than your renewal offer and will save you a significant amount!  

In simple terms, we can identify competitive tariffs for our customers because we aim to match the needs of the customers to particular energy suppliers.

As part of the service, we liaise directly with your old supplier to inform them of the switch, so that’s one less job you need to think about! 

When you switch suppliers, you may find you end up with two active Direct Debits on your account, that is until your old supplier closes your account. However, the good thing is you’ll never have to pay for the energy you use twice, with any overpayments always refunded to you. To prevent this, you could look to cancel your old suppliers direct debit, but you need to think about the impact this cancellation may have on your business as any closing debits or credits will need to be paid using an alternative method, such as a cheque. 

Deemed rates usually apply to businesses that are either; new to the propertyhave terminated a contract but failed to switch to a new supplier or they have missed the contract end date and are not out of contractThese rates are extremely expensive an arguably the worst rates to be on…however the good news is that there is only a maximum of 28 days’ notice required to switch onto the cheapest electricity rates. 

VAT is normally charged at 20% on business energy. However, in certain circumstances a business energy customer can qualify to pay a reduced rate of VAT. 


Some of the circumstances this applies for include: 


  • Energy for charity non-business qualifying use 
  • Energy where the amount supplied does not exceed the domestic qualifying use de minimis limits.
  • Energy with at least 60% being eligible for qualifying use 

If you’re unsure if you qualify feel free to give one of our experts a call, so you can better understand how you make your declaration.
