At Utility King, we often see confusion when customers attempt to compare energy prices and notice two different figures: a price including VAT and a price excluding VAT. This raises a practical question: should you compare energy prices with VAT or without VAT? To answer this properly, we need to start from first principles — what VAT is, how it applies to domestic energy, and why it affects energy price comparison. Understanding this clearly ensures you do not misinterpret tariff pricing or overestimate potential savings.
What Is VAT?
VAT stands for Value Added Tax. It is a government-imposed consumption tax applied to goods and services. Businesses collect VAT on behalf of the government and add it to the final price paid by consumers. In the context of energy bills, VAT is applied to: electricity usage, gas usage, and standing charges. VAT is charged on the total bill amount — not just the energy consumed.
VAT Rate on Domestic Energy
Domestic Energy
Reduced VAT rate for households
Business Energy
Standard VAT rate (unless eligible for relief)
This distinction is important when comparing domestic energy tariffs versus commercial energy contracts.
Including vs Excluding VAT
Price Excluding VAT
This is the base energy rate before tax is added. It reflects the supplier's raw pricing structure. This figure is often used in business energy quotations or wholesale discussions.
Price Including VAT
This is the actual price you will pay as a domestic consumer. It includes unit rate, standing charge, and VAT applied to both. For household energy comparison, the including-VAT price is what matters most.
Why Show Prices Without VAT?
Business Energy Markets
Commercial customers often reclaim VAT, pay different rates, and operate under tax-adjusted structures. Excluding VAT pricing is relevant here.
Transparency & Regulation
Some suppliers display both figures to clearly show tax components. However, for residential households, excluding VAT pricing can create confusion if not interpreted correctly.
How VAT Affects Your Bill
VAT is applied to the entire bill — including standing charges.
Although VAT is a relatively small percentage compared to wholesale energy costs, it still increases the final amount you pay. When comparing energy prices with and without VAT, remember: VAT applies consistently across suppliers for domestic customers. It does not vary by supplier.
Compare With or Without VAT?
For domestic households, always compare prices including VAT.
Why? Because that is the real cost you will pay, VAT is mandatory and unavoidable, comparing excluding VAT figures understates actual expense, and all suppliers apply VAT at the same rate. Comparing excluding VAT figures does not provide a realistic assessment of your savings.
When Excluding VAT Does Matter
There are limited situations where excluding VAT comparisons are relevant:
- Business energy contracts
- VAT-registered entities
- Charities or organisations eligible for VAT relief
- Large-scale commercial procurement
In these cases, VAT treatment can vary. For domestic households, however, VAT should simply be included in total cost evaluation.
Misleading Comparisons
Confusion often arises when:
- One tariff is quoted excluding VAT
- Another is quoted including VAT
- Annual estimates omit standing charges
- Marketing highlights only unit rates
To avoid misleading comparisons, always confirm:
- Is VAT included?
- Are standing charges included?
- Is the estimate based on realistic annual usage?
Total annual cost including VAT is the only meaningful comparison metric.
Does VAT Change When You Switch?
No. Switching energy supplier does not change VAT rate, does not affect tax treatment, and does not alter regulatory obligations. VAT is determined by government policy — not by the supplier. Your energy switching decision affects pricing structure, not taxation.
Can VAT Change in Future?
Yes — governments can adjust VAT rates. If VAT rates change: all suppliers must apply the new rate, the change affects all domestic customers, and it is not supplier-specific. This reinforces why VAT is not a competitive differentiator between energy providers.
Utility King's Perspective
At Utility King, we encourage customers to focus on clarity. When comparing energy prices with and without VAT: domestic customers should always evaluate including-VAT figures, VAT does not vary between suppliers, the real comparison point is total annual cost including tax, and energy comparison becomes confusing when key elements are separated artificially.
The right way to compare energy deals is simple: Look at the full annual cost, including VAT, standing charges, and realistic usage. That is the number that matters.
