Business energy contract ending? What happens next and what to do

If your business energy contract ending date is coming up, it is worth acting before your current deal expires. Waiting too long can mean moving onto an out-of-contract rate, limiting your options, or rushing into a contract that does not properly fit how your business uses energy. 

For many small or medium-sized businesses, the right energy contract is not just about finding the lowest unit rate. It is about knowing what you will pay, avoiding unexpected costs, keeping admin simple and choosing a supplier you can trust if something needs sorting. 

At SmartestEnergy Business, we help switched on businesses take control of their energy overheads, protect against market uncertainty and work towards their green business goals. Our range of fixed, renewable and flexible products is designed to give businesses clearer choices and more confidence when renewal time comes around.

What happens when your business energy contract ends? 

When your business energy contract ends, you normally have three options: 

1. Renew with your current supplier 
2. Switch to a new supplier 
3. Do nothing and move onto an out-of-contract arrangement 

Business energy contracts can last for up to five years, and most suppliers will not let businesses switch before the end of the contract term. That makes your renewal window an important opportunity to compare your options properly. 

If you do not agree a new contract before your current one ends, what happens next depends on your contract terms. You may move onto an out-of-contract rate, a deemed contract or a rollover contract. These are not the same, but they are all outcomes that can happen when no new agreement is in place. 

At SmartestEnergy Business, if an existing customer has not renewed or switched supplier at the end of their contracted period, they are billed on our variable SmartFlex rates until they agree a new contract or leave supply. We are clear about this because businesses should know where they stand and have time to make an informed choice. 

Why acting early matters 

Energy renewal can be easy to put off, especially when you are running a busy business. But leaving it until the last minute can make it harder to compare quotes, ask the right questions and choose a contract that gives you the right balance of cost certainty, flexibility and service. 

• Starting early gives you time to: 
• Check your current rates and end date 
• Understand your annual usage 
• Compare quotes like for like 
• Review fixed, flexible and renewable options 
• Ask about standing charges, broker fees and other costs 
• Avoid moving onto deemed rates 
• Plan a smooth switch with minimal admin 

Ofgem rules require suppliers to provide clear renewal information for fixed-term contracts, including current prices, new prices and annual consumption. The maximum notice period for terminating a mid-market business contract can vary as these are generally negotiated on an individual basis. You should check your original terms to find the specific “renewal window” and expiry date. 

The earlier you review your options, the more control you have. 

What to check before your business energy contract ends 

1. Your contract end date and notice period 

Start by finding your contract end date and the last date for giving notice. These are not always the same thing. 

You should be able to find this information on your contract, latest bill, statement of account or online portal. It is important for businesses to understand their contract dates and renewal terms so they know when they can switch or agree a new deal. 

2. Your usage and meter details 

A good quote depends on accurate information. Before comparing suppliers, gather: 

• Your latest electricity and gas bills 
• Annual usage in kWh 
• Meter Point Administration Number, also known as MPAN, for electricity 
• Meter Point Reference Number, also known as MPRN, for gas 
• Site addresses 
• Current contract end dates 

Any planned changes to opening hours, equipment, premises or operations 

If you have multiple sites, it is especially important to understand whether all your contracts end at the same time. Aligning renewal dates can make future energy management simpler. 

Smart meter data can also help improve visibility. Ofgem reports that 61% of businesses now have smart meters, which can support more accurate usage data and reduce reliance on estimated reads. 

At SmartestEnergy Business, smart metering is part of how we help businesses stay in control. We provide access to usage data through SmartWeb and offer smart meter technology to support more accurate billing. 

3. Whether you need price certainty, flexibility or both 

Not every business needs the same type of energy contract. 

If you want protection against wholesale market movements, a fixed product may be a good fit. If your usage changes often or you want more flexibility, another product may suit you better. Fixed-rate contracts set a fixed unit price for the length of the contract, while variable products can move up or down over time base on market volatility.  

At SmartestEnergy Business, our product range includes: 

• SmartFix Standard, for businesses that want to fix against wholesale cost fluctuations 
• SmartFix Renewable, for businesses that want fixed pricing with renewable electricity 
• SmartFix Zero, for businesses looking for zero standing charges and zero carbon energy 
• SmartFlex, for businesses that require a flexible energy service

Our products are designed to help different businesses manage cost, certainty, flexibility and sustainability in a way that works for them. 

4. What is included in the price 

Business energy pricing is about more than the headline unit rate. Business energy bills can include wholesale costs, network costs, government schemes and levies, taxes such as VAT and Climate Change Levy, and third-party services such as broker commissions. 

Before choosing a new contract, ask: 

• What is the unit rate? 
• What is the standing charge? 
• Are any costs variable? 
• Are broker fees or commissions included? 
• How long is the price fixed for? 
• Are there any termination terms? 
• Will the supplier help you understand your bill? 

Clear pricing matters because the cheapest-looking quote is not always the easiest to manage. A better deal should be clear, comparable and suited to your business needs. 

5. Whether renewable energy is important to your business 

Renewal is also a good time to think about your sustainability goals. For many SMEs, renewable electricity is becoming part of how they demonstrate progress to customers, suppliers, employees and stakeholders. 

SmartestEnergy Business offers renewable electricity products verified by the Carbon Trust and backed by energy labels to prove your renewable credentials. This gives businesses a practical way to reduce their carbon impact with clearer evidence behind their renewable electricity supply. 

If renewable energy is part of your decision, ask suppliers to explain: 

• How their renewable product works 
• What certificates support the claim 
• Whether the product helps with reporting 
• What evidence you will receive 
• How easy it is to manage alongside your wider contract 

Sustainability should be clear and practical, not another layer of complexity. 

What if you are already out of contract? 

If your business energy contract has already ended, it is still worth acting now. Being out of contract does not mean you have missed your chance to improve your position. It usually means you may be on a temporary or variable arrangement that may not be the best option for your business. 

At SmartestEnergy Business, out-of-contract customers are billed on variable SmartFlex rates until they agree a new contract or leave supply. If you are out of contract, you can get a personalised quote to see whether there is a better option available. 

How to compare business energy suppliers 

When your business energy contract is ending, it can be tempting to focus only on price. Price matters, but it is not the only thing that affects the value of your next contract. 

When comparing suppliers, look for: 

• Transparent pricing with no hidden surprises 
• Clear billing and easy account management 
• Products that match your risk appetite 
• Good customer support 
• Smart meter and usage visibility 
• Renewable options with credible evidence 
• Flexible payment options 
• A switching process that is clearly explained 
• Support from people who understand business energy 

SmartestEnergy Business supports small and medium businesses with competitive standard and renewable products, flexible payment options, SmartWeb online account access, smart meter support and dedicated customer service. Since 2009, we have helped more than 100,000 small and medium businesses switch to a better energy deal. 

How long does it take to switch business energy supplier? 

The time it takes to switch can depend on your current contract, your credit check, your meter details and whether your existing supplier raises an objection. 

For electricity or gas, the earliest timeframe for switching to SmartestEnergy Business is approximately five working days, subject to approval and credit check. If your current supplier objects, for example because you are still in contract or have an outstanding balance, we will let you know. 

A good switch should feel effortless. That means clear communication, accurate details and no unnecessary disruption to your business.
