Cheapest Energy Supplier in My Area
Energy prices vary by postcode across the UK — the cheapest supplier in one area may not be the cheapest in another. Here’s how to find the best deal for your specific location.

Why do energy prices vary by area?
Energy prices in the UK vary by location because the cost of distributing gas and electricity differs across the country. The UK is divided into regional distribution networks and each network has different operating costs which are reflected in the standing charges and unit rates available in that area.
This means that two households using exactly the same amount of energy can pay different amounts depending on where they live. It also means the cheapest supplier or tariff in one area may not be the cheapest in another.
💡 Key point
National price comparison tables give you a rough guide but the only accurate way to find the cheapest supplier for your home is to compare using your specific postcode and usage.

While the cheapest tariff varies by postcode, here is a general overview of how energy prices compare across the main regions of Great Britain:
Figures are indicative based on typical household usage. Actual prices vary by postcode and tariff.
What affects your energy price?
Several factors determine how much you pay for energy beyond just which supplier you’re with:
📍 Your location — distribution network costs vary by region, affecting your standing charge and unit rate.
🏠 Your property — larger homes with poor insulation use more energy and pay more. Better insulation = lower bills.
⚡ Your tariff type — fixed tariffs lock your unit rate. Variable tariffs move with the market and the price cap.
📊 Your usage — how much gas and electricity you actually use has the biggest impact on your total bill.
🔌 Your meter type — Economy 7 and smart meters can unlock cheaper off-peak rates if you shift usage to off-peak times.
💳 Your payment method — paying by monthly direct debit is almost always cheaper than paying on receipt of bill or by prepayment meter.
How to switch to the cheapest deal in your area
Once you’ve found the cheapest tariff for your postcode, switching is straightforward and takes about 10 minutes. Your supply is never interrupted and your new supplier handles everything.
You’ll need your postcode, current supplier name and a recent meter reading. The switch itself typically completes within 5 working days.

Is Octopus Energy available in my area?
Octopus Energy is available across Great Britain — England, Scotland and Wales. They are not available in Northern Ireland which has a separate energy market.
Why is energy more expensive in rural areas?
Rural areas often have higher energy costs because the cost of maintaining the distribution network over longer distances is higher. This is reflected in higher standing charges in some rural postcodes.
Can I switch supplier if I rent?
In most cases yes — if you pay your energy bills directly to a supplier you can switch. If your landlord pays the bills and charges you, you would need their agreement. Check your tenancy agreement if you’re unsure.
How often should I compare energy deals?
You should compare deals at least once a year and always when your fixed tariff is coming to an end. The energy market changes regularly and a better deal may have become available since you last checked.
Will switching affect my energy supply?
No — your gas and electricity supply will never be interrupted when you switch supplier. The same pipes and cables deliver your energy regardless of who supplies it. Only the company billing you changes.
