Find the cheapest energy tariff for your postcode—this week
Energy prices can look similar on paper, but the cheapest energy tariff in your postcode can change week-to-week due to supplier pricing, regional network charges, and the type of meter you have. EnergyPlus compares whole-of-market home energy options available to you and highlights deals that may reduce your costs.
To provide a meaningful result, we ask for your postcode and a few essentials (like whether you want gas, electricity, or dual fuel). If you know your annual usage from your bill, we’ll use it—if not, we can still estimate based on household info.
Tip: “Cheapest” usually means the lowest estimated annual cost for your usage and meter, not just the lowest unit rate. We show both so you can compare properly.
What you’ll see when you check your postcode
Estimated monthly & yearly cost
We estimate what you’re likely to pay based on your usage and meter type—so you can compare like-for-like, not guess from unit rates alone.
Unit rates, standing charges & term
See the key pricing details that affect your bill, including standing charge differences across UK regions and tariff contract length.
Supplier features that matter
Payment method options, exit fees (if any), smart meter compatibility, and whether the tariff is fixed or variable.
Important: Some tariffs have limited availability (for example, only certain regions or payment methods). Your postcode check ensures you only see tariffs that should be available where you live.
Why the “cheapest tariff” depends on your postcode
In the UK, your energy bill isn’t determined by one national price alone. The cheapest energy tariff in your postcode this week can differ from a friend’s across the country—even if you pick the same supplier—because of regional factors and how your home uses energy.
Regional network costs
Distribution and transmission charges vary by region. These charges influence standing charges and overall tariff cost, so your postcode matters.
Meter type & payment method
Smart meters, prepayment meters, Economy 7, and payment method (Direct Debit vs pay on receipt) can all change which tariffs you can access and what they cost.
Your usage pattern
A tariff with a low unit rate but higher standing charge may suit high-usage homes, while low-usage homes may benefit from a lower standing charge.
Supplier pricing changes
Suppliers can update tariffs frequently. Checking “this week” helps you spot changes and avoid switching to a deal that’s no longer competitive.

How to find the cheapest energy tariff in your postcode
- Enter your postcode so we can match tariffs to your region and network charges.
- Tell us your setup (gas, electricity or dual fuel) and any known details from your bill (usage, tariff name, payment method).
- Review your results by estimated annual cost, unit rate, standing charge, term length and features.
- Switch if it suits you. If you proceed, you’ll get confirmation from the supplier before anything changes.
Will my supply be interrupted? Switching supplier should not interrupt your energy supply. Your gas and electricity keep flowing; only the billing provider changes.
Fixed vs variable vs tracker: what can be cheapest this week?
The cheapest option depends on your appetite for price changes and how long you want certainty. Here’s a practical comparison for UK households:
| Tariff type | How prices work | When it may be cheapest | Watch-outs |
|---|---|---|---|
| Fixed | Unit rates/standing charge stay the same for the term (e.g., 12 months). | When you want predictable bills and a competitive fixed deal appears in your region. | May include exit fees; can miss out if prices fall significantly. |
| Variable | Prices can change (often with notice), typically tracking broader market movements. | When you want flexibility or are waiting for better fixed deals. | Costs may rise; budgeting can be harder. |
| Tracker | Rates move in line with a defined reference (e.g., a market index) plus margin. | When market prices are trending down and the tracker terms suit your risk level. | Exposure to spikes; check caps, notice periods, and how the tracker is calculated. |
| Time-of-use (e.g., Economy 7) | Different rates at different times (day/night). Best with compatible meter and usage pattern. | When you use a meaningful share of electricity off-peak (storage heaters, EV charging). | Day rate may be higher; only cheaper if your usage fits the schedule. |
Practical approach: If you’re unsure, compare by estimated annual cost for your postcode, then check the tariff term and any exit fees. The “cheapest” deal only helps if it suits how you live.
Regional considerations that affect your quote
Standing charge differences
Standing charges can vary by region and can meaningfully change your annual cost—especially for low-usage households.
All-electric homes vs gas
If you don’t have mains gas, the cheapest option may hinge on electricity unit rates and your heating type (heat pump, storage heaters, panel heaters).
Prepayment meters
Some tariffs are restricted for prepayment. If you can move to credit mode and it’s right for you, you may access more options.
Economy 7 and time-of-use
If you have an off-peak setup, the cheapest tariff is usually the one that matches your actual day/night split—not necessarily the lowest headline rate.
Common mistakes when searching for the cheapest energy deal
Only comparing unit rate
Standing charges can outweigh small unit-rate differences. Compare the estimated annual cost for your usage.
Ignoring meter/tariff compatibility
Economy 7 and prepayment require compatible tariffs. A “great deal” isn’t helpful if it doesn’t fit your meter.
Not checking exit fees or term
A fixed tariff can be good value, but check whether leaving early costs money and whether the term suits you.
FAQs: cheapest energy tariff by postcode
Can you really show the cheapest tariff in my postcode this week?
We can show tariffs that are likely available for your postcode and estimate which looks cheapest for your usage and meter setup at the time of searching. Tariffs can change quickly, so “this week” is a useful snapshot rather than a guarantee. Your final tariff details are confirmed by the supplier before you switch.
Do I need my bill to compare energy deals?
A recent bill helps because it shows your tariff name and annual usage (kWh). If you don’t have it, you can still check tariffs by postcode and provide an estimate; we’ll show results that you can refine later.
Will switching save me money straight away?
Savings depend on your current tariff, usage and any exit fees. If you’re out of contract or on a higher-priced variable tariff, you may see savings sooner. We focus on estimated annual cost to show the likely impact.
What if I have a prepayment meter?
You can still compare options, but tariff availability may be more limited. If you’re eligible to change to a credit meter and it suits your circumstances, additional tariffs may become available.
Is it better to fix or stay variable right now?
It depends on your priorities. Fixed deals offer certainty; variable and tracker deals offer flexibility but can change. The most useful way to decide is to compare the estimated annual cost for your postcode and check the contract term and exit fees.
Does switching affect my credit score?
Some suppliers may run eligibility checks depending on payment method and circumstances. If you’re concerned, you can compare options and choose suppliers/tariffs that best match your situation.
