How do I find the cheapest energy tariff in my postcode today?

Enter your postcode (and current supplier if known) to compare available gas and electricity tariffs for your exact area. Prices can vary by region, meter type, and payment method, so postcode-based comparisons give the most accurate ‘today’ results.

Why do energy prices vary by postcode in the UK?

UK energy rates can differ by region due to distribution network costs (the charges to move energy through local networks). Your meter type (standard, smart, Economy 7), usage profile, and payment method can also affect the cheapest tariff available in your postcode.

Is the cheapest tariff always the best option?

Not always. The ‘best’ tariff depends on more than unit rates—check the standing charge, contract length, exit fees, and whether prices are fixed or variable. If you expect your usage to change (e.g., working from home), a slightly higher unit rate could still cost less overall depending on standing charges and terms.

What information do I need to compare energy tariffs accurately?

For the most accurate comparison, you’ll need your postcode, fuel type (gas, electricity, or dual fuel), meter type (standard, smart, Economy 7), and your typical usage (kWh) or annual spend. If you don’t know your usage, you can estimate—your results will be more accurate once you confirm actual kWh from a recent bill.

Can I switch energy suppliers if I’m in a fixed-term contract?

Yes, but you may need to pay an exit fee if you leave a fixed tariff early. Many suppliers waive exit fees during the final 49 days of your contract. Checking your current tariff end date and any exit fees helps you decide whether switching now is worth it.

How long does it take to switch energy supplier in the UK?

In most cases, a switch completes within around 5 working days under the UK’s faster switching process, though timings can vary. Your energy supply won’t be interrupted—only the company billing you changes.

Will switching affect my smart meter?

Usually, smart meters continue to work after switching. If you have an older SMETS1 meter, smart features may be limited with some suppliers, but this has improved significantly as meters are enrolled into the national DCC network. Your meter will still record readings regardless.

Is it cheaper to get dual fuel (gas and electricity) from the same supplier?

Sometimes, but not always. Dual fuel can be convenient and may include discounts, but the cheapest option can also be separate suppliers for gas and electricity. Comparing both routes for your postcode is the best way to confirm the lowest total cost.

What’s the difference between a fixed and a variable energy tariff?

A fixed tariff locks your unit rate and standing charge for a set period, helping you budget (exit fees may apply). A variable tariff can change with the supplier’s pricing and market conditions, offering flexibility but less price certainty.

How can I reduce my energy bills after finding a cheaper tariff?

After switching to a cheaper tariff, you can reduce bills further by submitting regular meter readings (or using a smart meter), checking your direct debit is aligned to usage, improving insulation and draught-proofing, using efficient heating controls, and running appliances at off-peak times if you have an Economy 7/EV tariff.

Why compare energy by postcode with EnergyPlus?

Whole-of-market focus

We aim to compare eligible home energy tariffs across the market so you can see competitive options rather than guessing based on headline rates.

Postcode-accurate availability

Tariffs can vary by region and network. Using your postcode helps filter to deals that should be available where you actually live.

Understand real annual cost

We look beyond “cheap unit rate” claims. The standing charge plus your expected usage is what usually decides the best value.

Fixed vs variable explained

See what you gain and what you trade off: price certainty on fixed deals versus flexibility on variable tariffs.

Support for different meter types

Standard credit, smart meters and (where applicable) prepayment options can affect availability and pricing. We help you navigate this.

No pressure to switch

You’re comparing to make a better decision. If the numbers don’t stack up, you can keep your current tariff.

Comparing energy is about suitability as well as price: meter compatibility, payment method, contract length and exit fees can all matter.

How we identify the cheapest tariff for your postcode

When people ask for the cheapest energy tariff “today”, they usually mean: what can I actually switch to now, in my area, for my home. Here’s how EnergyPlus helps you get there.

You enter your postcode so we can match you to your regional electricity distribution area and filter results to local availability.
We consider tariff types (fixed, variable and any relevant smart options) and whether you’re comparing electricity, gas or dual fuel.
We estimate annual cost using standing charge + unit rates based on your usage or your current spend (where provided).
You compare like-for-like and check contract length, exit fees (if any), and payment method requirements.
You choose whether to switch. If you proceed, your new supplier normally handles the changeover with minimal disruption.

What “cheapest” usually means

Most households save when the total annual cost is lower. A tariff can have a low unit rate but a high standing charge, which may not be cheapest for lower-usage homes.

Why “today” matters

Tariffs can be withdrawn, updated or limited by region. Comparing “today” ensures you’re viewing currently available options for your postcode, not outdated deals.

Quick reference: what affects your price

Factor	Why it changes the cheapest tariff	What to check
Standing charge	A daily cost regardless of usage; big driver for low-usage homes.	Compare standing charge alongside unit rate.
Unit rate (p/kWh)	Most important for higher-usage homes; affects every kWh you use.	Check electricity and gas separately.
Region (postcode)	Network costs vary by region so prices can differ across the UK.	Always compare with your actual postcode.
Payment method	Direct Debit tariffs can differ from pay-on-receipt options.	Confirm how you want to pay.
Meter type	Smart, standard and prepayment meters can have different tariff availability.	Check your current meter and compatibility.

Why the cheapest energy tariff can differ by postcode

Two households with the same usage can still see different “cheapest” deals because energy pricing includes regional elements. That’s why comparing by postcode is more accurate than searching generic “UK cheapest tariff” lists.

Regional network costs

Your electricity distribution region affects the charges suppliers pay, which can flow into unit rates and standing charges.

Tariff availability

Some tariffs are offered nationally, while others may be limited or priced differently depending on region and metering arrangements.

Local usage patterns

Suppliers price for risk and demand. In some regions, pricing and available options can reflect wider network and market conditions.

If you’ve recently moved, your “cheapest” tariff may change even if your usage doesn’t. Comparing by your new postcode is the fastest way to confirm.

Common mistakes when searching for the cheapest energy tariff

1) Comparing unit rate only

Standing charges can outweigh small differences in unit rate, especially if you use less energy. Always compare the estimated annual cost.

2) Forgetting meter type

A tariff may not be available for your meter (for example, some prepayment arrangements). Compare options that match your setup.

3) Ignoring contract length and exit fees

A cheaper fixed tariff may come with an exit fee. If you plan to move or expect rates to change, flexibility can matter.

4) Using national “top deals” lists

Lists often don’t reflect regional pricing or availability. Your postcode is the key to seeing what’s actually open to you.

FAQs: cheapest energy tariffs by postcode

Is there a single cheapest energy supplier for the whole UK?

Not usually. The “cheapest” depends on your postcode, usage, meter type, and how you pay. That’s why we start with your postcode and calculate estimated annual costs.

Will switching interrupt my gas or electricity supply?

In normal circumstances, no. Your energy keeps flowing and the switch is handled administratively between suppliers. You’ll usually just receive a final bill from your old supplier and a welcome pack from the new one.

What if I don’t know my annual kWh usage?

That’s common. If you can, check your latest bill for kWh. If not, provide your best estimate or current spend — we’ll still help you compare likely cheaper options and explain the assumptions.

Are fixed tariffs always cheaper than variable?

Not always. Fixed tariffs can offer price certainty, but the cheapest option depends on current market pricing, contract length, and any fees. We’ll show you the estimated annual cost for each eligible tariff.

Can I compare if I have a prepayment meter?

Yes. Availability and pricing can differ, so it’s important to compare the right set of tariffs. Enter your postcode and details and we’ll help you see the options that may apply.
