How do I find the cheapest local energy tariff by postcode?

Enter your UK postcode and current energy details to compare live tariffs available in your area. Prices can differ by region and meter type, so postcode-based results are the most accurate way to find the cheapest local energy tariff.

Why does the cheapest energy tariff vary by postcode?

Energy tariffs can vary by postcode because regional network charges and supplier pricing differ across electricity distribution areas and gas regions. Your meter type and payment method can also affect which deals you can access.

Is the cheapest tariff always the best option for me?

Not always. The lowest unit rate may come with a higher standing charge, exit fees, or different contract terms. Comparing the total estimated annual cost (based on your usage) and the tariff conditions helps you choose the best-value option.

What information do I need to compare energy prices by postcode?

You’ll typically need your postcode, fuel type (gas, electricity or dual fuel), current supplier/tariff (if known), your meter type (standard, smart, or prepayment), and an estimate of your annual usage (kWh) or recent bill details for best accuracy.

Can I switch energy supplier if I’m in a contract?

In many cases you can switch, but you may be charged an exit fee depending on your current tariff terms. When you compare, check whether exit fees apply and whether the savings outweigh any fees.

How long does it take to switch to a cheaper energy tariff?

Most UK switches are completed within around 5 working days, and your supply won’t be interrupted. You’ll continue to receive energy as normal while your new tariff is set up.

Will switching affect my smart meter or direct debit setup?

Your smart meter should continue to work after switching in most cases, and your new supplier will set up a new direct debit if you choose that payment method. You’ll be informed of any changes during the switch process.

What’s the difference between fixed and variable energy tariffs?

Fixed tariffs lock in unit rates (and sometimes standing charges) for a set period, offering price certainty. Variable tariffs can change with market conditions or supplier pricing decisions, which may be higher or lower over time.

Do prepayment customers get access to the cheapest local energy tariffs?

Some deals are available for prepayment meters, but the range of tariffs can be smaller than for credit meters. Comparing by postcode and selecting your meter type shows the cheapest options you can actually switch to.

Compare the cheapest energy tariffs available in your postcode

In the UK, the cheapest local energy tariff isn’t always the same across the country. Your postcode helps identify your electricity distribution region, which affects standing charges and unit rates—so the “best deal” in one area may not be cheapest in another. EnergyPlus compares whole-of-market home energy tariffs available where you live, so you can focus on real options rather than generic averages.

Tip to find cheaper deals If you’re on a standard variable tariff, checking fixed deals available in your postcode can reduce the price you pay per kWh—especially if your standing charge is high locally.

Why the “cheapest” energy tariff is different by postcode

Your postcode helps determine your electricity distribution region and the network costs built into the standing charge and unit rate. Suppliers price tariffs differently across regions, and availability can also depend on meter type and payment method. Comparing locally prevents you from choosing a tariff that looks cheap nationally but is expensive where you live.

Local standing charges

Standing charges can vary meaningfully by region. If you use less energy, your local standing charge can matter as much as the unit rate.

Meter & tariff compatibility

Economy 7, smart meters, and prepayment meters can change which tariffs are available and how your consumption is charged.

Realistic bill estimates

A cheap unit rate can be outweighed by a higher standing charge (or vice versa). We show estimated costs so you can judge the true cheapest deal.

How to find the cheapest local energy tariff (postcode check)

If you want the cheapest tariff available in your area today, focus on the numbers that actually drive your bill: unit rate (p/kWh), standing charge (p/day), and how they apply to your meter and payment method. EnergyPlus helps you compare these quickly using your postcode.

Enter your postcode to identify your local network region and show tariffs available to your address.
Choose fuel type (dual fuel, electricity-only, or gas-only) and your payment method (e.g. monthly Direct Debit).
Review cheapest results by estimated annual cost, then check the breakdown of unit rate and standing charge.
Switch with confidence by completing the application form. Your new supplier handles the switch—no interruption to supply.

What “whole-of-market” means here

We aim to compare tariffs from across the market for home energy, including fixed and variable options, subject to supplier participation, eligibility, and availability in your postcode.

Energy tariff prices explained (so you can spot the real cheapest)

Two homes on the same tariff can pay different amounts due to different usage. That’s why the cheapest energy tariff by postcode should be judged using a bill estimate based on your consumption—not just headline rates. Use the guide below to interpret what you see in your comparison results.

Price element	What it means	Why it affects “cheapest”
Unit rate (p/kWh)	The price for each unit of energy you use.	High users benefit more from a lower unit rate.
Standing charge (p/day)	A daily fixed charge for keeping your home connected.	Low users can overpay on high standing charges—these vary by region.
Fixed vs variable	Fixed stays the same for the term; variable can change with the supplier’s rates.	Fixed can protect you from rises; variable offers flexibility but less certainty.
Exit fees	A fee for leaving a fixed tariff early (not always present).	A “cheap” tariff may cost more if you expect to move or switch again soon.
Payment method	How you pay (Direct Debit, prepay, pay on receipt).	Some tariffs price differently depending on payment method and meter type.

If you want to sanity-check your current deal, look at your latest bill and note your standing charge and unit rates. Then compare like-for-like based on your postcode.

Regional considerations when comparing energy by postcode

Electricity distribution regions

Electricity network costs vary by region and can impact the standing charge and unit rate you’re offered. A postcode check helps ensure you’re comparing tariffs priced for your specific region—not a national headline figure.

Meter types and time-of-use

If you have Economy 7 (or similar), you’ll typically see separate day/night rates. The cheapest deal depends on your night usage share and the local day/night pricing for your region.

Prepayment vs credit meters

Pay-as-you-go and credit meters can have different tariffs available. We let you filter by payment method so you see applicable prices in your postcode.

Moving home

If you’re moving soon, prioritise low or no exit fees and check whether a fixed deal allows moving with you. The cheapest tariff today isn’t helpful if it’s expensive to leave.

Common mistake: choosing on unit rate alone

A lower unit rate can still cost more overall if the standing charge is higher in your region. Always compare using estimated annual cost for your usage and postcode.

FAQs: cheapest local energy tariff by postcode

Can two postcodes have different prices for the same supplier?

Yes. Suppliers often set regional pricing (especially for electricity) because local distribution costs vary. Your postcode helps show tariffs priced for your region, including local standing charges and unit rates.

Does a “cheapest tariff” mean the lowest unit rate?

Not necessarily. The cheapest tariff for you is the one with the lowest estimated total cost for your usage, after considering unit rates, standing charges, and any fees.

Will switching interrupt my gas or electricity supply?

No—your supply stays on. The switch is administrative, and your new supplier coordinates it. You’ll usually just provide meter readings around the switch date.

What information do I need to compare by postcode?

At minimum: your postcode and whether you want gas, electricity, or dual fuel. If you have them, your MPAN/MPRN and an estimate of annual usage improves accuracy—especially for Economy 7 or multi-rate meters.

Can I compare if I’m on prepayment?

Yes. Select prepayment as your payment method. We’ll focus on applicable tariffs in your postcode and show you the rates and estimated costs for PAYG options.

How often do local tariff prices change?

Tariff availability and prices can change at short notice. That’s why a postcode comparison “today” is useful—results reflect what’s available for your area at the time you check.
