How to find the cheapest tariff for your postcode
Energy tariffs aren’t one-size-fits-all. Your postcode helps identify your electricity distribution region and supports more accurate pricing. Add a few details (fuel type and payment method), and we can rank tariffs by estimated annual cost, then by relevant features.
- Enter your postcode to tailor results to your area and check availability.
- Select what you want to compare (dual fuel, gas only or electricity only).
- Choose your payment method (Direct Debit, prepayment, or pay on receipt of bill).
- Review tariffs by estimated annual cost, unit rates and standing charges.
- Apply to switch—your new supplier typically handles the move, and your supply stays on.
What “cheapest” should mean when comparing
To avoid false savings, look beyond a single number. A genuinely cheaper tariff for your home usually combines:
Competitive unit rates
What you pay per kWh matters most for higher-usage homes and electric heating.
Reasonable standing charges
Daily charges can outweigh small unit-rate savings, especially for low-usage properties.
Contract terms you can live with
Fixed deals may have exit fees; variable deals can change. Choose what fits your risk tolerance.
Payment & meter compatibility
Not all tariffs are available for prepayment meters or Economy 7—postcode helps, but meter type seals the fit.
Good to know: Switching supplier won’t interrupt your energy supply. In most cases, you’ll keep the same pipes and wires—the billing changes, not your connection.
Why energy tariffs vary by postcode
While many tariff structures look similar across the UK, your postcode can affect the price you pay—particularly for electricity—because it helps identify your regional distribution network and related charges. Availability can also change based on meter type and payment method.
| Factor | Why it matters | What you can do |
|---|---|---|
| Electricity distribution region | Regional network costs can influence standing charges and unit rates. | Use postcode comparison and focus on estimated annual cost, not just a headline unit rate. |
| Meter type | Standard, smart, Economy 7 and prepayment meters can have different tariff availability. | If you’re unsure, check your bill or meter display; we’ll help you compare the right tariff set. |
| Payment method | Direct Debit tariffs can be priced differently to pay-on-receipt or prepayment. | Compare using your real payment method so savings estimates are realistic. |
| Consumption (kWh) | The cheapest tariff for a low-usage flat may not be cheapest for a larger family home. | Use annual usage if you know it. Otherwise, start with an estimate, then refine later. |
| Tariff type & terms | Fixed vs variable can change your risk and potential price changes over time. | If you value predictability, choose fixed; if flexibility matters, compare variable and check the details. |
Common misconception: A “postcode-only” quote can’t be perfect on its own. Your address area helps, but meter type, payment method and usage are usually what decide which tariff is truly cheapest for your household.
Regional considerations across the UK
Energy costs can look different depending on where you live. Postcode comparison helps you see tariffs with pricing aligned to your region, but it also helps to understand what can vary.
England, Scotland & Wales
Different electricity distribution regions and standing charges can influence the best-value tariff. Comparing by postcode reduces the risk of choosing a deal that looks cheap but isn’t in your area.
Urban vs rural postcodes
While your supplier options are typically similar, network charges and metering arrangements can differ. If you have Economy 7, make sure you compare against Economy 7-compatible tariffs.
All-electric homes
If you don’t have gas, electricity unit rates matter even more. You may benefit from fixed deals for stability, or Economy 7 if you use storage heating and can shift usage overnight.
Prepayment meters
Some tariffs are limited for prepayment. Comparing correctly can highlight savings and also show whether switching to another payment method could open up more deals (where suitable).
Avoid these common mistakes when searching “cheapest energy tariff by postcode”
- Comparing the wrong payment method: Direct Debit vs prepayment can produce very different results.
- Ignoring standing charges: Especially costly for low-usage households.
- Choosing solely on rate: Exit fees and contract length can change the real cost of switching.
- Not checking meter compatibility: Economy 7 and smart tariffs need the right meter setup.

FAQs: cheapest energy tariffs by postcode
Can I really find the cheapest tariff using just my postcode?
Your postcode is the best starting point because it helps match tariffs to your region. For an accurate “cheapest for you” result, add your payment method, meter type (if known) and usage estimate. That’s why our form asks for those essentials.
Do you compare all suppliers?
EnergyPlus aims to provide whole-of-market comparisons for UK domestic energy where available. Results can vary by region and eligibility, and not every tariff is available to every customer.
Is the cheapest tariff always a fixed tariff?
Not always. Fixed tariffs offer price certainty for the unit rate over the fixed term, but can include exit fees. Variable tariffs can be cheaper at times and often have more flexibility. The best choice depends on price, terms and your preferences.
Will switching affect my supply?
No—your gas and electricity supply continues as normal. The change is administrative (billing). Your new supplier will usually manage the process, including contacting your current supplier.
What information do I need to switch?
Typically: your address and postcode, contact details, payment method, and sometimes your meter details. If you have it, your annual usage in kWh (from your bill) helps produce the most accurate comparisons.
Can I compare if I have a prepayment meter?
Yes. Select “Prepayment meter” in the form so we can focus on tariffs and options suitable for your setup. Availability can differ, so postcode comparison helps narrow to relevant deals.
Still unsure? Start a comparison using your postcode and the closest match for payment method. You can refine your results once you find your meter details or usage figures.
