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

Enter your postcode and a few details about your home (e.g., whether you pay by Direct Debit and your typical usage). We’ll show available tariffs in your area so you can compare estimated costs and choose the cheapest option for your postcode today.

Why does the cheapest energy tariff vary by postcode?

Energy prices can differ by region because network and distribution costs vary across the UK. That means the same supplier may have different unit rates and standing charges depending on your postcode.

Is the cheapest tariff always the best option?

Not always. The lowest estimated cost is important, but you should also check tariff type (fixed vs variable), contract length, exit fees, and payment method. If you value price certainty, a fixed tariff may be better even if it isn’t the absolute cheapest today.

What information do I need to compare tariffs accurately?

For the most accurate results, have your postcode, current supplier, tariff name (if known), payment method, and an estimate of annual usage in kWh (from a recent bill). If you don’t know usage, you can still compare using typical consumption estimates.

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

You can usually switch at any time, but a fixed tariff may include an exit fee. Many suppliers also allow a fee-free switch in the final weeks of your contract. Always confirm any exit fees before you change tariff or supplier.

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

A switch typically completes within around 5 working days for most domestic energy switches. You won’t lose supply during the process—only the billing supplier changes.

Will my energy supply be interrupted when I switch?

No. Switching supplier does not interrupt your gas or electricity supply. Your energy continues to come through the same pipes and wires; only your supplier and tariff change.

Do I need a smart meter to get the cheapest local tariff?

Not necessarily. Many competitive tariffs are available without a smart meter. However, some smart tariffs and time-of-use plans require one, which can be beneficial if you can shift usage to cheaper periods.

Are there any hidden fees when switching energy tariffs?

There shouldn’t be hidden fees. The key costs to check are exit fees on your current tariff and any conditions such as payment method requirements. Always review the tariff’s unit rates, standing charge, and contract terms before switching.

What’s the difference between unit rate and standing charge when comparing tariffs?

The unit rate is what you pay per kWh of energy used. The standing charge is a daily fixed amount for being connected to the network. The cheapest tariff for your postcode depends on both, plus how much energy you use.

What “cheapest” means in practice

We rank tariffs by estimated annual cost for your household and postcode, based on the rates and standing charges available in your region. Where multiple tariffs are close, we also flag key differences like contract length, exit fees, payment method requirements and any restrictions for prepayment or Economy 7 meters.

How to get the cheapest local tariff (step-by-step)

If you’re looking for the cheapest energy by postcode today, the goal is simple: compare the tariffs you can actually switch to, then pick the one with the lowest estimated annual cost for your usage.

Enter your postcode to match regional pricing and availability.
Select fuel and meter type so we show compatible tariffs (important for prepayment and Economy 7).
Add payment method (Direct Debit vs pay on receipt can affect pricing).
Review the cheapest options — we’ll highlight unit rates, standing charges, contract length and exit fees.
Switch when you’re happy. You should keep the same energy supply — only your supplier/tariff changes.

When a fixed tariff can be cheapest

A fixed deal may be cheapest if the unit rate and standing charge beat current variable pricing, especially if you value predictable bills. Always check exit fees if you might move or switch again soon.

When a variable tariff can be cheapest

A variable tariff can work if you want flexibility and you’re planning to switch quickly if prices change. Check the current rates and whether there are any discounts tied to payment method.

Why the cheapest energy tariff depends on your postcode

Energy pricing in Great Britain can vary by region due to distribution costs and other factors. That means two households with identical usage can see different standing charges and unit rates depending on where they live. Comparing with your postcode helps ensure you’re looking at tariffs priced for your local area.

Factor	What it affects	Why it matters for “cheapest”
Regional electricity distribution area	Standing charge and unit rate components	Two tariffs with the same name can price differently across regions.
Meter type (smart/credit/prepay/E7)	Eligibility and rate structure	The cheapest tariff for a standard meter may not be available for prepayment or Economy 7.
Payment method	Discounts, tariffs offered	Some of the lowest prices assume monthly Direct Debit.
Usage (kWh)	Estimated annual cost ranking	A low standing charge can be best for low usage; a low unit rate can win for higher usage.

A quick way to sanity-check “cheap”

If two deals look similar, compare (1) standing charge, (2) unit rate, and (3) contract terms. The lowest headline unit rate isn’t always cheapest once the standing charge and your usage are included.

Common mistakes when searching “cheapest energy by postcode”

Avoid these pitfalls to make sure the tariff you choose is genuinely the cheapest for your home — not just a deal that looks good on a comparison table.

Comparing without your meter type

Prepayment and Economy 7 tariffs can differ. If you don’t filter by meter type, you may see prices you can’t switch to.

Ignoring standing charges

For low-usage homes and smaller flats, a higher standing charge can outweigh a lower unit rate over the year.

Not checking exit fees and term length

A fixed tariff can look cheapest today but cost more if you need to leave early (moving home, switching again).

Using estimated usage that’s far off

If possible, use kWh from a bill. If not, pick a home type that matches you; it improves accuracy of the “cheapest” ranking.

Already on a tariff — should you switch?

If you’re out of contract or on a standard variable/deemed tariff, comparing your postcode rates is a sensible first step. If you’re already on a competitive fix with low exit fees, the cheapest option today may only be marginally better. The form helps you quantify the difference.

Cheapest local energy tariff FAQs

Do energy prices really change by postcode?

They can vary by region. The same supplier can have different standing charges and unit rates depending on the local distribution area linked to your postcode.

Is the cheapest tariff always dual fuel?

Not always. Dual fuel can be convenient, but separate gas and electricity suppliers can sometimes be cheaper. We’ll show what’s best based on your details.

Can I switch if I’m renting?

In many cases, yes — if you’re responsible for paying the energy bills. If your landlord includes bills, you usually can’t change the supplier yourself.

What if I have a prepayment meter?

You can still compare. Some tariffs are restricted, so it’s important to filter for prepayment to avoid seeing deals you can’t access.

How often should I check for cheaper tariffs?

If you’re on a variable or out-of-contract tariff, checking every few months can help. If you’re on a fix, compare as you approach the end date and check exit fees.

Will my supply be interrupted if I switch?

Switching supplier should not interrupt your energy supply. Your gas and electricity still come through the same pipes and wires.
