Unit rate (p/kWh)
The price you pay for each kilowatt-hour of energy you use. Electricity and gas have separate unit rates. Lower unit rates typically mean lower bills if your usage is high.

-
2) We show tariffs you can switch to
See a range of plans from UK energy suppliers, including fixed-rate, variable, and green tariffs. Filter by price, contract length and payment method.
-
3) Choose and switch online
Pick the tariff that suits you and start the switch online. There’s no interruption to supply — your new supplier handles the changeover.
What to compare when choosing an energy deal
Standing charge (p/day)
A daily fee for maintaining your connection and network costs. Lower standing charges can help low-usage households and second homes.
Tariff type and length
Fixed tariffs lock in a rate for a set term, while variable tariffs can move up or down. Check the contract length and whether there are exit fees.
Exit fees
Some fixed deals charge if you leave early. Balance any fee against the savings from switching now or later.
Payment method
Direct debit discounts often apply. Prepayment and pay-on-receipt-of-bill options may have different rates and terms.
Green credentials
Consider tariffs backed by renewable electricity or carbon-offset gas if sustainability matters to you.
Energy tariff types explained
Fixed-rate tariffs
Your unit rate and standing charge are fixed for the contract term (e.g., 12–24 months). Bills still vary with usage. Ideal if you want price certainty.
Variable-rate tariffs
Rates can go up or down usually in line with wholesale costs and the Ofgem price cap. No fixed end date; exit fees are often lower or none.
Dual fuel vs single fuel
Dual fuel means both gas and electricity with the same supplier. It can be convenient and sometimes cheaper, but always compare against separate deals.
Economy 7 / multi-rate
Cheaper off-peak electricity rates if you can shift usage to night-time. Works well with storage heaters and EV overnight charging.
Prepayment tariffs
Pay-as-you-go via key, card or smart prepay. Helps with budgeting but unit rates can be different to direct debit. Emergency credit rules apply.
Green and renewable tariffs
Electricity backed by renewable certificates and/or supplier generation. Check fuel mix disclosures and any carbon offset programmes.
Quick comparison table
| Tariff type | Pros | Cons | Best for |
|---|---|---|---|
| Fixed | Price certainty, easy budgeting | May include exit fees; less flexible if prices fall | Households wanting stability |
| Variable | Flexible, often no exit fee | Rates can rise with market conditions | Those preferring flexibility |
| Economy 7 | Cheaper off-peak kWh | Day rates higher; needs usage shift | EV owners, storage heating |
| Prepayment | Control over spending | Different rates; top-up required | Budget-focused users |
Understanding the Ofgem price cap
The Ofgem energy price cap limits the maximum unit rates and standing charges that suppliers can charge customers on standard variable tariffs in Great Britain (England, Scotland and Wales). It changes periodically to reflect costs. The cap is not a cap on your total bill — the amount you pay depends on how much energy you use.
- Applies to default and standard variable tariffs in Great Britain
- Does not apply in Northern Ireland (separate market and regulation)
- Fixed tariffs can be above or below the cap, depending on the deal
When comparing, look beyond the headline and consider your typical annual cost based on your usage. We calculate this for you during comparison.
Business energy comparison
For SMEs and larger organisations, energy can be a major overhead. Comparing business electricity and gas contracts helps control costs and cash flow.
Half-hourly and non-half-hourly meters
We support a range of business meter types, including multi-site portfolios. Have your MPAN/MPRN and recent invoices ready for the most accurate quotes.
Contract start dates and renewals
Many suppliers allow quotes up to several months ahead of renewal. Lock in rates in advance to gain cost certainty.
Billing and payment options
From fixed-term contracts to pass-through charges, choose billing that matches your risk appetite and usage profile.
Green energy and renewable tariffs
If sustainability is a priority, consider tariffs backed by renewable electricity certificates. Some suppliers also invest in wind, solar or hydro generation, or offer carbon-offset gas. Review each tariff's fuel mix disclosure and environmental claims.
- 100% renewable electricity options available from many suppliers
- Check whether green power is matched annually or on a granular basis
- Look for independent certifications and transparent reporting
Smart meters and your tariff
Smart meters automatically send readings to your supplier, improving billing accuracy and enabling time-of-use tariffs. Installation is typically free from your supplier. You can still switch supplier with a smart meter; functionality may vary depending on meter type and compatibility.
Practical ways to reduce your energy costs
Pay by fixed monthly direct debit
Many suppliers offer lower prices for direct debit compared with other payment methods.
Submit regular meter readings
Ensure bills reflect actual usage. Smart meters help automate this.
Improve efficiency
Small changes like LED lighting, draught-proofing and smart thermostats can reduce consumption.
Choose the right tariff type
If you prefer certainty, a fixed tariff may suit you. If flexibility matters, a variable tariff may be better.

Compare nowEnergy price comparison FAQs
Is there any interruption to my gas or electricity when I switch?
No. Your energy physically comes from the same network. Only your billing supplier changes, so there’s no interruption to supply.
How long does a switch take?
Most domestic switches complete within 5–21 days, depending on supplier processes and cooling-off periods. Business contracts vary by meter type and start date.
Do I need my current supplier’s permission to switch?
No. Unless you’re in debt on a prepayment meter or within a fixed-term contract’s exit-fee window, you can usually switch freely.
What information do I need for the most accurate quote?
Your postcode, meter type, and recent usage in kWh (or monthly spend). You’ll find usage on your annual statement or latest bill. We can estimate if you don’t know.
Are the cheapest tariffs always the best?
Not always. Consider exit fees, customer service, green credentials, and whether the tariff suits your usage pattern (e.g., off-peak charging).
Does the Ofgem price cap limit my total bill?
No. The cap limits unit rates and standing charges on certain tariffs, but your total bill depends on how much energy you use.
Can I compare and switch in Northern Ireland?
Northern Ireland has a separate energy market. Availability of tariffs and switching options differs from Great Britain.
