Every month, thousands of UK households search for the cheapest energy deals available right now — and for good reason. Energy prices don't change once a year anymore.
There is no permanent cheapest energy supplier. Monthly changes happen because of market dynamics.
A deal that was cheapest last month may already be gone. This is why live comparison matters more than headlines.
When suppliers advertise "cheap" energy, they often mean different things that may not suit your situation.
Monthly figures alone are misleading.
While exact suppliers vary, the cheapest deals this month usually fall into these categories:
Often 12–24 months, priced below standard variable tariff, best for budget certainty.
Ideal for low-usage homes, flats, single occupants, second homes.
Renewable energy no longer costs more. Some green deals now undercut standard tariffs.
One common mistake is assuming if a supplier is cheapest for electricity, they're cheapest for gas. Not true.
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.
Cheap energy deals often vanish because of market realities, not because they're scams.
Pro Tip: If you see a good deal, delaying can cost you. Act when you find competitive pricing.
Yes. With UtilityKing, you can compare deals without pressure or spam.
No spam. No pressure. Just clear comparison.
Prioritise low standing charges. Unit rate matters less than fixed costs.
Focus on low unit rates. Standing charges matter less proportionally.
Avoid high standing charge tariffs. Many "cheap" deals are poor value here.
Fixed tariffs often win long-term. Variable tariffs expose you to winter spikes.
The biggest savings come from: Leaving expensive variable tariffs, avoiding loyalty penalties, and escaping high standing charges.
UtilityKing is built for real-time accuracy, not marketing hype.
