Find today’s cheapest home energy tariff in your postcode

If you’ve searched for the cheapest energy tariff for my postcode, you’re in the right place. Energy prices can differ across the UK because suppliers set tariffs based on regional distribution costs, meter type and how you pay. That’s why a “national” deal you see online may not be the best option for your address.

Use the form to tell us your postcode and a couple of details about your home energy setup. We’ll help you compare tariffs available where you live—looking at the things that actually matter when you’re trying to reduce bills: unit rates, standing charges, tariff length and exit fees.

Tip: The “cheapest” tariff is usually the one with the lowest estimated annual cost for your typical usage—not necessarily the lowest unit rate. Standing charges and your consumption pattern can change the result.

Whether you have a standard credit meter, prepayment, or a smart meter, postcode-based comparison helps surface the tariffs that genuinely apply to you.

How to check the cheapest energy tariff by postcode

When you compare energy tariffs, it’s easy to get stuck on a single number. In reality, your best option depends on where you live and how your home uses energy. Here’s the simplest way to get relevant results today.

  1. Enter your postcode (and your details) in the form above to start the comparison.
  2. We match tariffs to your area based on regional distribution costs and availability.
  3. Compare the real cost—unit rate + standing charge—then check contract length and exit fees.
  4. Choose and switch if a tariff fits. Your energy supply stays on during the switch.

Good to know: In most home switches, there’s no engineer visit and no interruption to your energy. Your new supplier usually handles the changeover with your old supplier.

What to have to hand (optional but helpful)

  • Your latest bill (to confirm tariff name and rates)
  • Whether you pay by Direct Debit, cash/cheque, or prepayment
  • Whether you have a smart meter (and if you’re on any time-of-use tariff)
  • Rough annual usage in kWh (if available)

What affects the cheapest energy tariff in my postcode?

Two households can live in different parts of the UK, use the same amount of energy, and still see different “cheapest” tariffs. That’s because tariffs reflect a mix of regional and household-specific factors.

Factor Why it changes your cheapest tariff What to look for
Region / postcode Distribution charges vary across the UK, which can affect unit rates and standing charges. Compare estimated annual cost for your postcode, not a headline rate.
Meter type Prepayment, standard credit and smart/time-of-use can have different available tariffs. Make sure the tariff is compatible with your meter and payment setup.
Standing charge A low unit rate can be offset by a high daily standing charge—especially for low-usage homes. Consider your usage: low users often benefit from lower standing charges.
Tariff type Fixed deals can offer price certainty; variable deals can change with market conditions. Check term length, price protection, and any exit fees.
Payment method Some suppliers price differently for Direct Debit vs pay-on-receipt. Compare tariffs using the payment method you’ll actually use.

Cheapest doesn’t always mean best—here’s how to decide

If you want price certainty

A fixed tariff may suit you—especially if your budget is tight. Check the end date and any exit fees before switching.

If you want flexibility

A variable tariff can be easier to leave if a better deal appears. Focus on today’s rates and how they compare in your postcode.

Common mistakes when searching for the cheapest energy tariff

If you’ve been googling “cheapest electricity tariff” or “lowest gas price”, it’s easy to be pulled towards offers that don’t fit your home. Avoid these pitfalls to get a true like-for-like comparison.

Comparing without your postcode

Regional charges can shift the “cheapest” result. Start with a postcode-based search to filter out irrelevant tariffs.

Ignoring standing charges

A tariff with a low unit rate can still cost more overall if the standing charge is high—especially for smaller households.

Not checking tariff terms

Exit fees, contract length, and price review clauses can affect whether a “cheap” deal stays cheap over time.

Practical approach: Compare by postcode, shortlist by estimated annual cost, then choose the tariff that suits your budget (fixed vs variable) and your switching flexibility.

Cheapest energy tariff by postcode: FAQs

Why does the cheapest tariff change by postcode?

Your postcode maps to a regional electricity distribution area. Distribution and network costs can differ between regions, and suppliers may price tariffs accordingly. That’s why comparing with your postcode produces more accurate results than relying on national averages.

Is the cheapest energy tariff always a fixed deal?

Not always. Fixed tariffs can be cheaper at times and provide price certainty, but some variable tariffs may be lower on the day you compare. The best choice depends on your priorities: budget stability, flexibility to leave, and the full cost (unit rate + standing charge).

Do I need my exact usage to compare?

No. If you have your annual kWh figures from a bill, that can improve accuracy, but you can still compare without them. Many comparisons use typical usage estimates and then refine once you confirm details.

Will my supply be interrupted if I switch?

In most household switches, no. Your energy continues to flow as normal, and the change is handled between suppliers. If anything extra is required (for example, meter-related changes), you’ll be informed before proceeding.

Can I compare dual fuel and electricity-only?

Yes. Many households choose dual fuel for convenience, but electricity-only or gas-only can be the right fit depending on your home. A postcode-based comparison helps you see which option is cheapest based on availability and pricing.

Is this page for business energy?

No—this page is for home energy in the United Kingdom. If you’re looking for business tariffs, you’ll need a business-specific comparison.
