The Ultimate Guide to Electricity Business Tariffs in 2025
Introduction: Why Electricity Business Tariffs Matter
Electricity costs can make or break a business’s profitability—especially for energy-intensive sectors. In 2025, navigating the UK’s energy market requires understanding the different electricity business tariffs available and how to select the best option based on your business’s size, usage, and growth strategy.
Whether you’re managing a startup, SME, or multi-site organisation, this comprehensive guide will walk you through what electricity business tariffs are, how they work, how to compare them, and how to optimise your energy contract.
What Are Electricity Business Tariffs?
Electricity business tariffs are pricing plans tailored for commercial energy users. Unlike domestic tariffs, business contracts are customised based on consumption, meter type, credit score, and site location.
These tariffs govern:
-
How much you pay per kilowatt hour (kWh)
-
Standing daily charges
-
Billing frequency
-
Green energy options
-
Flexibility or fixed rates
Types of Electricity Business Tariffs
Choosing the right tariff type is critical for budget planning and risk management. Here are the main categories:
1. Fixed-Rate Tariffs
-
The unit price (p/kWh) and standing charges remain constant for the contract’s duration.
-
Ideal for predictable costs and budgeting.
-
Contract lengths: 12, 24, 36, or 60 months.
-
Best for SMEs and budget-conscious businesses.
2. Variable Tariffs
-
Prices fluctuate with wholesale market rates.
-
You might benefit when market prices drop.
-
Risk of unexpected increases.
-
Useful for short-term contracts or businesses that can tolerate price variability.
3. Pass-Through Tariffs
-
Charges are separated: energy cost + non-energy costs (transmission, metering, taxes).
-
Allows large businesses to hedge or manage risk actively.
-
Transparent but requires close monitoring.
4. Deemed/Out-of-Contract Tariffs
-
Extremely expensive.
-
Applies when a contract ends and no renewal or switch is made.
-
Businesses should avoid this by planning ahead.
Understanding Business Electricity Pricing
Electricity business tariffs are composed of several pricing components:
| Component | Description |
|---|---|
| Unit Rate (p/kWh) | Price per kilowatt hour of usage |
| Standing Charge | Daily fixed cost to maintain your electricity supply connection |
| VAT | 20% standard rate for most businesses |
| Climate Change Levy (CCL) | Government tax on non-renewable energy, unless on a green tariff |
| Broker Commission | Often included in unit rate (if applicable) |
