Choosing a business electricity provider may seem straightforward, but many UK businesses unknowingly lock into contracts that cost them thousands in avoidable fees and overcharges. Whether you’re a start-up or an established company, getting this decision wrong can impact your bottom line for years.
At Scalex Technology, we’ve helped hundreds of UK businesses avoid these pitfalls. In this guide, we break down the top 7 most common mistakes when choosing a business electricity provider—and how to avoid them.
⚡ 1. Focusing Only on the Unit Price
It’s tempting to go for the lowest pence per kWh rate—but that’s not the full picture. Many suppliers offer low unit prices but hide high standing charges or sneaky fees elsewhere in the contract.
Tip: Always look at the total annual cost, not just the headline rate.
⚡ 2. Ignoring Contract Length and Flexibility

Some suppliers lock you into long-term contracts (up to 5 years) without offering break clauses or renewal flexibility. This can be a serious problem if energy prices drop or your business needs change.
Tip: Choose a provider with contract terms that match your business goals. Scalex can help you find flexible and fixed options that suit your needs.
⚡ 3. Not Comparing Multiple Suppliers
Many businesses stick with their current supplier or accept the first quote they receive. In a competitive market, this means you could be overpaying by 20% or more.
Tip: Let Scalex Technology compare rates across multiple UK business energy suppliers to secure you the best deal.
⚡ 4. Missing Out on Green or Renewable Options
With the UK pushing towards Net Zero, many businesses overlook opportunities to go green—either due to price concerns or lack of awareness.
Tip: Ask for renewable electricity options—Scalex can show you low-cost green tariffs that enhance your ESG credentials.
⚡ 5. Not Checking for Hidden Fees
Some suppliers include fees for:
- Meter readings
- Late payments
- Early termination
- Paper billing
Tip: Always ask for a breakdown of all charges, and have a broker like Scalex review the contract before you sign.
⚡ 6. Forgetting to Renew or Cancel at the Right Time
Businesses that don’t renew or cancel in time are often rolled over into expensive default rates, also known as “out-of-contract rates”.
Tip: Set reminders—or let Scalex manage renewals and cancellations for you, ensuring you’re always on the best deal.
⚡ 7. Not Reviewing Energy Usage First
Choosing a supplier without knowing your actual usage is like buying a car without knowing the mileage. It can lead to overestimated costs or mismatched tariffs.
Tip: Review at least 12 months of energy data. Scalex offers a free consumption analysis to make this step easy.
