Why the Cheapest Energy Deals Change Every Month

There is no permanent cheapest energy supplier. Monthly changes happen because of market dynamics.

  • Wholesale price movements
  • Suppliers launching short-term fixed deals
  • Hedging strategy changes
  • Price cap updates (for variable tariffs)

A deal that was cheapest last month may already be gone. This is why live comparison matters more than headlines.

What "Cheapest" Actually Means in Energy

When suppliers advertise "cheap" energy, they often mean different things that may not suit your situation.

The True Cheapest Deal Is:

  • Lowest total annual cost
  • Based on your postcode
  • Based on your actual usage
  • Includes standing charges properly
  • Considers tariff length

Monthly figures alone are misleading.

Cheapest Energy Deals This Month: What's Typically Winning in 2026

While exact suppliers vary, the cheapest deals this month usually fall into these categories:

Fixed Tariffs Below Price Cap

Often 12–24 months, priced below standard variable tariff, best for budget certainty.

Low Standing Charge Tariffs

Ideal for low-usage homes, flats, single occupants, second homes.

Green Tariffs at Standard Prices

Renewable energy no longer costs more. Some green deals now undercut standard tariffs.

Cheapest Electricity vs Cheapest Gas: They're Not Always the Same

One common mistake is assuming if a supplier is cheapest for electricity, they're cheapest for gas. Not true.

Important Note:

Suppliers price gas and electricity separately, even on dual fuel deals. UtilityKing shows cheapest electricity tariffs, cheapest gas tariffs, and whether dual fuel actually saves money.

Why Some "Cheap" Deals Disappear Overnight

Cheap energy deals often vanish because of market realities, not because they're scams.

  • Wholesale prices move rapidly
  • Suppliers hit customer limits
  • Hedging windows close
  • Competitive pressure changes

Pro Tip: If you see a good deal, delaying can cost you. Act when you find competitive pricing.

Cheapest Energy Deals by Household Type

Low-Usage Homes

High-Usage Homes

Focus on low unit rates. Standing charges matter less proportionally.

Flats & Apartments

Avoid high standing charge tariffs. Many "cheap" deals are poor value here.

Families & Large Homes

Fixed tariffs often win long-term. Variable tariffs expose you to winter spikes.

When Is the Best Time This Month to Switch?

  • "Perfect" timing
