What details do I need to get an accurate quote?

Your postcode, whether you need electricity, gas or both, your current supplier and tariff (if known), meter type (standard, Economy 7/E10, prepayment, smart), and annual consumption in kWh. If you do not know usage, we can estimate using Ofgem Typical Domestic Consumption Values (TDCV).

Will my energy supply be interrupted if I switch?

No. Your gas and electricity are delivered through the existing networks and will not be interrupted. Only your billing company changes. The switch is completed remotely.

Do you include exit fees and discounts in your comparison?

Where provided by suppliers, we include early exit fees, standing charges, unit rates, discounts and payment method adjustments in your projected annual cost. Always check tariff-specific terms before confirming a switch.

Are green energy tariffs more expensive?

Not always. Many suppliers offer competitively priced 100% renewable electricity tariffs backed by REGOs. Compare both price and environmental credentials to choose what suits you best.

What if I’m in debt to my current supplier?

If you have a credit meter and a debt over 28 days, your current supplier may need to agree the switch. Prepayment customers can usually switch if the debt is under £500 per fuel under the Debt Assignment Protocol.

Do I need a smart meter to switch?

No. You can switch with traditional or smart meters. Some time-of-use tariffs require a smart meter; your new supplier may offer installation if needed.

Energy Tariff Comparison in the United Kingdom

Q: How does UK energy tariff comparison work?

We collect publicly available tariff data and partner rates from a wide range of UK suppliers. You provide your postcode and estimated usage, then we estimate your annual costs by applying unit rates, standing charges and any discounts to your consumption profile. You can sort by price, tariff type or green content before initiating a switch with the chosen supplier.

Q: What is the difference between fixed and variable tariffs?

Fixed tariffs lock in your unit rate and standing charge for a set term (e.g., 12 months). Variable tariffs can change, usually in line with the Ofgem price cap for standard variable tariffs. With fixed tariffs you may pay exit fees if you leave early; variable tariffs usually have no exit fees.

Q: Can I compare Economy 7 or prepayment tariffs?

Yes. You can compare Economy 7/E10 tariffs by entering your day/night usage split, and prepayment tariffs by selecting the prepayment meter option in the form.

UK energy tariff types explained

Fixed-rate tariffs

Lock in unit rates and standing charges for a set term (e.g., 12 or 24 months). Good for budgeting. Check for early exit fees and whether rates are fixed for both fuels if you choose dual fuel.

Variable tariffs (including Standard Variable Tariffs)

Rates can change at the supplier’s discretion. Standard Variable Tariffs (SVTs) are typically influenced by the Ofgem price cap. Usually no exit fees, but costs may rise or fall during your contract.

Economy 7 and Economy 10

Two-rate tariffs with cheaper night rates and higher day rates. Best if a significant portion of your electricity is used off-peak (e.g., storage heaters, EV charging). You’ll need an E7/E10 meter and a realistic day/night split.

Prepayment tariffs

Pay as you go using a key, card or smart prepay. Helps manage budgets, but unit rates can differ from direct debit. If you have prepay debt under certain limits, you may still be able to switch under the Debt Assignment Protocol.

Smart meter and time-of-use tariffs

Dynamic or time-of-use pricing rewards shifting consumption to off-peak periods. Requires a compatible smart meter. Ideal for EV owners or flexible households that can move usage.

Green and renewable tariffs

100% renewable electricity tariffs are backed by REGOs. Some suppliers also invest in new renewable generation or offer carbon-offset gas. Compare both price and environmental credentials.

Don’t know your usage? We’ll estimate it

If you can’t find your kWh on a recent bill, we can estimate your consumption using Ofgem Typical Domestic Consumption Values (TDCV). These are industry-standard annual figures used for comparison.

Typical Domestic Consumption Values (guide)

Electricity (single-rate) medium home: around 2,700 kWh/year
Gas medium home: around 11,500 kWh/year
Economy 7 electricity: around 4,200 kWh/year with a typical 42% night usage split

Figures are indicative and may be updated by Ofgem. Actual consumption varies by home size, insulation, heating type and behaviour.

Find the right numbers on your bill

Look for annual consumption in kWh for each fuel.
Note your meter type (standard, Economy 7/E10, smart, prepayment).
Record your payment method and current tariff name for accurate comparisons.

Price cap, standing charges and exit fees

The Ofgem energy price cap sets a maximum average price that suppliers can charge customers on default (standard variable) tariffs. It does not cap your total bill; your spend depends on how much energy you use.

Standing charge: A daily fee you pay regardless of usage, set per fuel.
Unit rate: The price per kWh you consume.
Exit fees: Many fixed tariffs apply a fee if you leave before the end date. Check terms before switching.

When you compare, we calculate an estimated annual cost using your usage and each tariff’s rates and charges. Always review the Key Facts and Tariff Information Label before confirming.
