Introduction
As a small business owner, every expense matters. From rent and wages to inventory and marketing, managing overheads effectively is essential to your long-term sustainability. One area where many businesses routinely overpay is energy. Without a regulated price cap like domestic tariffs, business energy rates can vary dramatically between suppliers and contract types. The good news is that there are more options than ever before to find the best energy deals for small business.
In this comprehensive guide, we will walk you through how energy pricing works for small businesses, how to compare and secure the best deals, and which suppliers are leading the market in 2025. Whether you are running a small retail shop, a bakery, an office-based firm, or a startup studio, optimising your energy contract could save your business hundreds or even thousands of pounds per year.
Why Small Businesses Need Tailored Energy Deals
Unlike large corporations, small businesses operate with tighter budgets and less energy usage. That means they may not benefit from the same bulk discounts but are more exposed to market volatility and hidden fees.
The best energy deals for small business are designed to:
- Offer price stability
- Simplify billing and contract management
- Provide smart meter integration
- Include renewable energy options
- Match usage patterns without excessive standing charges
Customising your energy contract to your specific business type and usage profile is key to cutting unnecessary costs.
How Business Energy Pricing Works
Understanding how energy is priced can help you identify better deals. Business energy pricing typically includes the following:
Unit Rate (pence per kWh)
The price paid for each kilowatt-hour of electricity or gas consumed.
Standing Charge (daily fee)
A fixed amount charged every day regardless of consumption. This covers network maintenance and administrative costs.
Climate Change Levy (CCL)
A government-imposed tax on non-renewable energy. Exemptions apply for some sectors and green tariffs.
VAT
Most businesses pay 20 percent VAT on energy, though some qualify for the reduced 5 percent rate.
Metering Charges
For manual meters or advanced metering systems, additional charges may apply.
Business rates are unregulated and negotiated directly with suppliers, making it vital to compare based on total annual cost rather than just unit rates.
Types of Energy Contracts Available to Small Businesses
Fixed Rate Contracts
The unit rate is locked for the duration of the contract, typically between 1 and 3 years.
Pros:
- Price certainty
- Ideal for budgeting
Cons:
- No benefit if prices fall
- Exit fees may apply
Variable Rate Contracts
Prices fluctuate in line with the wholesale market.
Pros:
- Potential to benefit from falling prices
- Flexible terms
Cons:
- Costs may rise unexpectedly
- Harder to budget
Rolling or Deemed Contracts
If a business does not renew or renegotiate its contract, it is placed on an out-of-contract rate which is often much higher.
Recommendation: Never allow your business to fall into a deemed rate. Always review and act before your contract expires.

How to Find the Best Energy Deal for Your Business
Step 1: Review Your Energy Usage
Collect the following information from your bills:
- Annual electricity and/or gas consumption (in kWh)
- Contract end dates
- Type of meter (single, dual, half-hourly, smart)
This information allows suppliers to generate accurate quotes.
Step 2: Use a Trusted Energy Comparison Tool
Platforms like Switch‑Us.net allow you to compare real-time offers from major suppliers, saving time and ensuring you are presented with the best available rates.
Step 3: Compare Full Contract Details
Do not focus solely on the unit rate. Always check:
- Total cost over 12 months
- Standing charge amounts
- Exit fees
- Metering charges
- Smart meter installation terms
- Renewable energy inclusion
Step 4: Check Supplier Reputation
Read independent reviews and business ratings to ensure the supplier offers good customer service and billing transparency.
Green and Renewable Energy Deals for Small Business
Sustainability is becoming a key concern for consumers and investors. Choosing a green energy tariff is increasingly accessible and often competitively priced.
Benefits of Renewable Energy Tariffs:
- Alignment with net-zero goals
- Positive brand association
- Eligibility for environmental grants
- Exemption or discount on Climate Change Levy
Leading Suppliers for Green Tariffs:
- Octopus Energy
- Good Energy
- E.ON Next
- Ecotricity
When comparing green tariffs, look for REGO certification and transparent carbon offsetting policies.
Smart Metering and Usage Insights
Smart meters provide automated, accurate readings and usage tracking. Most suppliers offer free smart meter installation for small business customers.
Benefits include:
- No estimated bills
- Real-time visibility into usage
- Easier to identify waste or inefficiency
- Improved budgeting
Make sure to request a smart meter installation when signing your new contract.
Reducing Energy Use: Practical Tips for Small Businesses
Even with the best energy deal, you can reduce your bills further through improved energy efficiency.
- Upgrade to LED lighting
- Install programmable thermostats
- Turn off non-essential equipment overnight
- Service boilers and HVAC systems regularly
- Use smart plugs and timers
- Conduct monthly energy audits using smart meter data
- Encourage employee energy-saving habits
These practices are low-cost and can result in long-term savings.
What to Avoid When Choosing an Energy Deal
Avoid these common pitfalls when selecting a new energy contract:
- Signing without comparing at least three offers
- Ignoring standing charges
- Focusing solely on unit price
- Overlooking contract length and exit clauses
- Missing renewal dates and falling into default rates
- Choosing suppliers with poor customer support history
Being thorough in your comparison will help you avoid expensive mistakes.
How Switching Energy Suppliers Works
Switching is simple, does not interrupt your supply, and is typically handled entirely by your new provider.
The process:
- Compare and select a new energy supplier
- Sign the new contract (can be done up to 12 months in advance)
- Provide a final meter reading at the switch date
- New supplier takes over billing and customer service
The transition takes between 2 and 3 weeks. Your new provider will manage all the paperwork.
Dual Fuel vs Single Contracts
Many suppliers offer bundled energy plans for both electricity and gas.
Advantages of Dual Fuel:
- One monthly bill
- Potential for bundled discounts
- Easier contract management
However, it is still worth comparing the electricity and gas contracts separately, as prices may vary when purchased individually.
Final Checklist Before Signing
- Do you know your average usage in kWh?
- Have you compared total costs from at least three suppliers?
- Have you checked standing charges, contract length, and exit clauses?
- Does the deal include a smart meter installation?
- Is the tariff renewable or partially offset?
- Are you aware of when your contract renews?
Once you can answer yes to all of these, you are ready to proceed.
