How to find the cheapest electricity provider in 2025

  1. Check your postcode and usage: Electricity rates vary by region. If you don't know your annual kWh, choose an estimate and refine later.
  2. Compare unit rates and standing charges: The cheapest provider for a low user isn't always cheapest for a high user. Look at the total estimated annual cost.
  3. Choose tariff type: Fixed, variable (price-cap tracked) or time-of-use. Pick the one that fits how and when you use energy.
  4. Switch online in minutes: No engineer visit for standard switches, no interruption to supply. Your new provider handles the process.

What makes one electricity provider cheaper than another?

  • Your region (distribution area): Network costs differ across the UK, so rates vary by postcode.
  • Tariff type: Fixed-price tariffs lock rates for a set term; variable tariffs can change and often follow Ofgem's energy price cap; tracker and time-of-use tariffs vary by wholesale or time of day.
  • Standing charge: A daily fee to maintain your connection. Lower users often benefit most from low standing charges; higher users focus on the unit rate (p/kWh).
  • Payment method and billing: Monthly Direct Debit and online billing usually cost less than pay-on-receipt or prepayment.
  • Smart meter: Enables access to some of the cheapest time-of-use and tracker-style deals.
  • Usage profile: Economy 7/Economy 10 users who shift consumption to night-time can save with cheap off-peak rates.

Ofgem's energy price cap limits what suppliers can charge on standard variable tariffs. The cap updates periodically and differs by region and payment method. Fixed and certain specialist tariffs can sit above or below the cap.

Tariff types in 2025 explained

Fixed-rate tariffs

Lock your unit rate and standing charge for 12–24 months. Best if you want price certainty. Early exit fees may apply if you switch before the end date.

Standard variable tariffs

Rates can go up or down and typically track the price cap. Often the default when a fixed deal ends. No or low exit fees are common.

Tracker and time-of-use

Smart tariffs where prices vary with wholesale costs or by time of day. Great for flexible users, EV charging or households that can shift usage to off-peak times.

Economy 7 / Economy 10

Two-rate metering with cheaper night-time electricity and higher daytime rates. Works well with storage heaters or night-time heavy usage.

Cheapest electricity provider UK 2025: FAQs

Who is the cheapest electricity supplier in the UK in 2025?

There isn't a single provider that is always cheapest for everyone. Prices depend on your region, meter type, payment method and usage. Enter your postcode to see live deals tailored to your home.

Is it better to choose a fixed or variable tariff in 2025?

It depends on your preference and the market outlook. Fixed tariffs give price certainty for a set period, while variable tariffs can change and usually track the energy price cap. If you value certainty, consider a fix; if you want flexibility and potential falls, a variable might suit you.

Will my power be cut off when I switch providers?

No. Switching is seamless under Ofgem rules. Your electricity supply continues throughout; only your billing provider changes.

What do unit rate and standing charge mean?

The unit rate is what you pay per kilowatt-hour (kWh) of electricity used. The standing charge is a daily fee to keep your home connected. The cheapest overall tariff balances both based on your usage.

How accurate are the prices I see?

We update pricing feeds frequently, but suppliers can change rates at short notice. Always review the final tariff details before confirming your switch.

Can renters switch electricity provider?

Yes, if you pay the bill directly. Check your tenancy agreement for any clauses, but Ofgem rules generally allow renters to switch. If your landlord pays the bill, ask them to compare tariffs on your behalf.

Important information

  • Prices and availability shown depend on your postcode, meter type, usage and payment method.
  • Standard variable tariffs are influenced by the Ofgem price cap, which updates periodically and varies by region.
  • Estimated savings are based on information you provide and typical usage assumptions if you select an estimate.
  • Always read key terms, including exit fees and contract length, before switching.
