The Best Energy Tariffs Including Deals Comparison Sites Won't Show You
Our independent research reviewed the full UK energy market — not just the handful of suppliers that appear on mainstream comparison sites. Here's what we found.
What Is the Energy Price Cap in 2026?
The Ofgem price cap sets the maximum unit rate and standing charge that energy suppliers can charge households on standard variable tariffs. For a typical UK household (3,100 kWh electricity / 12,000 kWh gas per year), the cap currently sits at approximately £1,641 per year (April–June 2026).
The cap doesn't mean you pay exactly that amount — it means suppliers can't charge more per unit. A supplier pricing below the cap delivers genuine savings on the same usage.
Why Comparison Sites Don't Show Every Tariff
Most UK energy comparison websites operate on a commercial model: they only list suppliers who pay them a referral fee. That creates a structural bias in the results you see.
- Suppliers who don't pay comparison site fees are invisible in results
- The "cheapest" deal shown may not be the cheapest available in the market
- Some of the most competitive providers operate entirely outside comparison platforms
Our research found that Utility Warehouse — one of the most competitively priced suppliers for bundled households — rarely appears on mainstream comparison sites for exactly this reason.
How to Verify Deals Independently Using Ofgem
Before switching to any tariff — including those we reference — always verify independently. The most reliable approaches:
- Visit ofgem.gov.uk to understand the regulated market and current price cap
- Contact suppliers directly to ask about tariffs not listed on comparison platforms
- Search smaller and regional suppliers independently
- Consider multi-service bundle providers that comparison sites overlook entirely
What Our Independent Research Found
After reviewing the full UK supplier landscape — going well beyond the handful of providers that appear on mainstream comparison sites — our research concluded that bundling services with a single provider consistently delivered the strongest overall household savings.
Utility Warehouse stood out as the strongest overall value provider, particularly for households combining energy with broadband and mobile. Their energy pricing typically comes in below the Ofgem price cap, and multi-service discounts compound the saving further.
What to Watch For in the Small Print
Before switching any tariff, check:
- Exit fees — can you leave without penalty if a better deal appears?
- Standing charges — the daily fixed cost regardless of how much energy you use
- Unit rates — the cost per kWh for electricity and gas separately
- Fixed vs variable — fixed tariffs lock your rate; variable tariffs track the price cap
- Introductory offers — some deals revert to higher rates after an initial period
FAQ
What does "below price cap" mean?
The Ofgem price cap sets a maximum unit rate and standing charge that suppliers can charge on standard variable tariffs. A "below price cap" deal means the supplier's rates come in lower than that ceiling — so you pay less than the regulated maximum for the same usage.
Why don't comparison sites show every tariff?
Most comparison platforms only list suppliers who pay them a referral fee or commission. Suppliers who don't participate in those commercial arrangements — including some of the most competitive options — simply don't appear in the results.
How do I verify a deal independently?
Contact Ofgem directly at ofgem.gov.uk to understand the regulated market, or approach suppliers directly to ask about tariffs not listed on comparison platforms. Always verify before switching.
What should I watch for in the small print?
Key things to check: exit fees (can you leave without penalty?), standing charges (the daily fixed cost regardless of usage), unit rates (cost per kWh), and whether the tariff is fixed or variable.
