How to find the cheapest energy tariff (postcode-specific)
The cheapest tariff for your friend in another town might not be the cheapest for you. To find the best value today, the comparison needs to match your location and how your household uses energy.
- Enter your postcode to match tariffs to your regional network charges.
- Select your fuel type (dual fuel, electricity only, or gas only) and how you pay.
- Choose your meter type (standard, Economy 7/two-rate, smart, or prepayment where relevant).
- Compare the right numbers: unit rates + standing charges, then factor in contract terms and exit fees.
- Pick a tariff and switch. Your supply stays on during the process—you won’t lose gas or electricity.
What you’ll need (ideal, but not essential)
- Estimated annual usage in kWh (from a bill, online account, or smart meter app)
- Your current payment method (Direct Debit, prepayment, or receipt of bill)
- Your meter type (standard vs Economy 7/two-rate)
- If you’re in-contract, your current tariff end date (to avoid exit fees)
Tariff types explained (so “cheapest” means cheapest for you)
A tariff can look cheap at first glance but end up costing more if the standing charge is high, the unit rate doesn’t suit your usage pattern, or you’re hit with an exit fee. Use this guide to compare like-for-like.
| Tariff type | Best for | Watch-outs | How to judge cheapest |
|---|---|---|---|
| Fixed rate | Households wanting predictable unit rates for a set term. | Early exit fees, longer terms, and potentially higher standing charges. | Compare total estimated annual cost using your usage + check exit fee vs flexibility. |
| Variable | Flexibility, often with no exit fees. | Rates can change; cheaper today may not stay cheaper. | Compare today’s unit rate + standing charge; check how/when changes are applied. |
| Two-rate (Economy 7) | Homes using more electricity overnight (e.g. storage heaters). | Day rate may be higher; not ideal if most use is daytime. | Use your day/night split if you know it; otherwise estimate before deciding. |
| Green / renewable-backed | Customers prioritising environmental impact. | Definitions vary; check how the supplier matches renewable generation. | Compare total cost first, then assess the tariff’s green credentials and terms. |
| No-exit-fee | People who may move home or want to switch again soon. | Sometimes a slightly higher unit rate in exchange for flexibility. | Weigh small cost differences against the value of switching flexibility. |
When you compare, focus on the estimated annual cost for your usage, then sanity-check with the underlying rates. If a deal looks unusually cheap, it’s often due to assumptions about usage, payment method, or meter type.
Why energy prices differ by postcode in the UK
Energy tariffs aren’t identical across the country. Even with the same supplier and tariff name, you may see different unit rates or standing charges depending on where you live. This is normal and largely driven by regional costs in the electricity network.
Regional distribution charges
Electricity is delivered via regional network operators and the cost of maintaining local infrastructure can vary by area. Those costs influence tariff pricing.
Metering and payment method
Some tariffs and rates are only available for certain meter types or payment methods (e.g. Direct Debit). Your setup affects which deals you can access.
Gas vs electricity (and dual fuel)
The cheapest option for electricity may not be the cheapest for gas. Comparing dual fuel can simplify bills, but it’s worth checking each fuel if you’re cost-focused.
Availability can change
Suppliers may open or close tariffs, change pricing, or limit deals to certain regions. That’s why checking “today” matters.
If you’re moving home, compare using the new postcode. Tariff availability and pricing can change even across nearby areas.
Common mistakes when searching for the cheapest tariff
Comparing only unit rates
Standing charges can make a low unit rate tariff more expensive overall. Always consider the full estimated annual cost.
Ignoring exit fees or end dates
Switching early can trigger fees on some fixed tariffs. If you’re close to your end date, timing the switch can reduce costs.
Choosing the wrong meter type
Economy 7/two-rate tariffs only make sense if enough usage is off-peak. Pick the correct meter setup for accurate results.
Using unrealistic usage estimates
If your kWh estimate is too low or high, the “cheapest” ranking can change. A recent bill helps, but a sensible estimate works too.

FAQs: cheapest energy tariff by postcode
What does “cheapest energy tariff” actually mean?
It usually means the tariff with the lowest estimated annual cost for your household, based on:
- your postcode (regional pricing/network costs)
- your fuel type (gas, electricity, or dual fuel)
- your meter type (standard, Economy 7/two-rate, smart, prepayment)
- your usage (kWh) and payment method
Will I lose supply when I switch?
No. Switching supplier doesn’t mean your gas or electricity is turned off. Your energy continues as normal while the admin changes in the background.
How often should I check for cheaper tariffs?
Many households review tariffs when a fixed deal ends, after moving home, or if prices change. If you’re on a variable tariff, it can be worth comparing periodically to see if a fixed tariff offers better value for your postcode.
Can I compare if I have a prepayment meter?
Yes. Choose the prepayment option in the form. Available tariffs can be different from Direct Debit tariffs, so selecting the correct payment method is important for accurate “cheapest” results.
Is a dual fuel tariff always cheaper?
Not always. Dual fuel can be convenient, but the cheapest electricity and cheapest gas tariffs may come from different suppliers. Comparing both options helps you decide what’s best overall for your home.
Do I need to give my phone number?
You can start the comparison with your postcode and details above. If you choose to proceed or want extra help, we may ask for further contact details to support your switch.

What customers say about comparing with EnergyPlus
The postcode check made it clear why prices differed from what I’d seen elsewhere. I switched to a fixed tariff that actually suited our usage.
I could see the standing charge and exit fee upfront, which helped avoid a deal that looked cheap but wasn’t.
The comparison was quick. I liked being able to filter for no-exit-fee options because we might move soon.
