⚡ Quick Answer (TL;DR)

The confirmed October–December 2026 electricity SVT (national Direct Debit average) is 26.32p/kWh + 54.83p/day (0% VAT from 1 October 2026 to 31 March 2027). Dual-fuel typical Direct Debit is £1,723/yr at TDCV 2,500 kWh electricity / 9,500 kWh gas (gas 7.97p/kWh + 29.68p/day, 5% VAT). Electricity-only at that TDCV is roughly £858/yr (2,500 × 26.32p + 365 × 54.83p).

A cheaper kWh is only a saving if the standing charge and exit fee still leave the annual total ahead of that illustration at your usage. We do not invent live supplier pence here.

Updated September 2026. This legacy guide previously led on Scottish Power’s Super Saver April 2026 Online tariff at 16.57p/kWh (and N Power Go Fix Apr 2026 at 19.34p/kWh) as the current cheapest unit rates. Those April-dated products are historical examples, not live picks. For current deals see Cheapest electricity-only deals UK and Cheapest energy deals UK — September 2026. Ofgem’s next announcement is 25 November 2026 for January–March 2027.

Finding the lowest electricity rate still means comparing suppliers, tariff types, and regional pricing — no single supplier is cheapest for every household. Use the October SVT pence as the hurdle, then get a written quote at your postcode.

Older copy on this URL listed a “cheapest suppliers” table headed by Scottish Power Super Saver April 2026 Online (16.57p/kWh, 43p/day) and N Power Go Fix Apr 2026 (19.34p/kWh), with several SVTs at 26.60p/kWh. That table is a spring 2026 snapshot. It is not a current ranking. Always verify prices with Switch's energy comparison tool before switching.

Note: the UK dual-fuel Direct Debit cap is £1,723/year for 1 October–31 December 2026 (published 26 August 2026). April–June’s £1,641 figure is historical. Ofgem also publishes typical dual-fuel illustrations for prepayment (£1,678) and standard credit (£1,861) in the same quarter — payment method changes the standing charge, not just the kWh.

Average Electricity Cost Per kWh by UK Region

Your location directly affects what you pay. The national Direct Debit average for October–December 2026 is 26.32p/kWh with a standing charge of 54.83p/day. Regional unit rates and standing charges still vary: London often combines a higher unit rate with a lower standing charge; Yorkshire and the North often reverse that pattern; North Wales & Mersey and North Scotland typically have some of the highest standing charges.

We are not republishing the old regional pence table (London 28.42p / 38.54p/day, Yorkshire 26.52p / 56.07p/day, and so on). Those figures sat under an earlier cap and would be misleading as “current”. Ofgem publishes regional tables. A typical household at TDCV 2,500 kWh electricity pays about £858/year on the national electricity SVT illustration — not the old 2,700 or 2,900 kWh presentations, and not a dual-fuel total.

Low-usage homes should watch the standing charge; high-usage homes should watch the unit rate. Run both at your postcode.

6 Types of Electricity Tariffs Available in the UK

1. Fixed-rate tariffs

Your unit price locks in for 12 to 24 months. Best for households that want predictable bills through winter. Exit fees apply if you leave early, typically £50 to £150. A fix is worth it if the annual total at your kWh beats 26.32p/kWh + 54.83p/day after those fees. Scottish Power’s Super Saver and N Power’s Go Fix were spring 2026 price leaders — treat those names as history, not a current shortlist.

2. Standard variable tariffs (SVT)

The unit price changes every 3 months following Ofgem’s cap. No exit fees, so you can switch anytime. From 1 October 2026 the national Direct Debit average is 26.32p/kWh (not the old 26.60p/kWh figure this page used). SVTs are the ceiling, not a bargain, unless no written fix beats them at your usage.

3. Economy 7 / time-of-use tariffs

These split the day into cheaper off-peak hours (typically overnight) and a higher daytime rate. They need a smart meter. Best for EV owners and households that can run dishwashers, washing machines, or storage heaters overnight. Off-peak pence vary by product — we do not invent a live overnight rate here. Octopus Go / Agile and similar EV tariffs are the usual place to start; compare the daytime rate as well as the night rate.

4. Green / renewable tariffs

These match consumption with renewable energy certificates (REGOs) from solar and wind. Some cost the same as a standard SVT; specialist green-gas products cost more. Octopus Energy and OVO’s green tariffs are popular options — confirm the unit rate on a quote, not a remembered April figure.

5. Dual-fuel tariffs

One supplier covers both electricity and gas. That simplifies billing and can reduce the combined cost versus two contracts — but not always. Compare dual-fuel vs separate deals using Switch's home energy comparison and the dated companion Dual fuel energy deals UK — September 2026.

6. Prepayment tariffs

You pay in advance via a smart meter or top-up. Best for some renters or households without a strong credit history. For October–December 2026 Ofgem’s typical dual-fuel prepayment illustration is £1,678 — slightly below the Direct Debit £1,723 typical, not the old Q1 pairing of £1,711 vs £1,758. Electricity-only prepay pence still differ by region; check the label.

How to Read a Named Supplier Without a Stale Rate Card

The previous edition of this guide walked through seven suppliers with April 2026 unit rates. Those pence are not current. Use this instead when you open a tariff information label:

  • Compare electricity unit rate + standing charge to 26.32p/kWh + 54.83p/day (national DD average, Oct–Dec 2026).
  • If the deal is dual fuel, also compare gas to 7.97p/kWh + 29.68p/day, or ignore this page’s dual-fuel £1,723 and use the electricity-only ~£858 illustration at 2,500 kWh.
  • Prefer £0 exit fees if your housing situation is unstable.
  • Scottish Power, E.ON Next, British Gas, OVO, EDF, SSE/Octopus-owned brands and challengers all still sell electricity — none of them has a permanent “cheapest kWh” crown.
  • Green options from the same brand are often a different (higher) unit rate. Read the name on the quote.

For a dated September 2026 list of electricity-only deals, use Cheapest electricity-only deals UK rather than this URL’s retired Super Saver table.

Smart Meter: Does It Help You Get Cheaper Electricity?

Yes. A smart meter unlocks three practical advantages:

  1. Time-of-use tariffs (EV overnight, Agile-style half-hourly) are only available with a smart meter.
  2. Accurate billing eliminates estimated reads, which can lead to overpayments.
  3. Usage insights help you see which appliances actually move the kWh.

Request a free smart meter installation through your current supplier. Most UK suppliers are obligated to offer them at no cost. Use Switch's energy comparison to find smart-meter-compatible tariffs after installation.

How to Switch Electricity Suppliers (5 Steps)

Switching typically takes under 21 days. Suppliers signed up to the Energy Switch Guarantee must complete the process within 5 working days.

  1. Gather your current bill. Note annual kWh, tariff name, and supplier.
  2. Compare suppliers by postcode. Unit rates vary by region. Use Switch's comparison tool.
  3. Check for exit fees. Fixed tariffs often charge £50 to £150 to leave early. Run the fee against the cash lead versus 26.32p/kWh + 54.83p/day.
  4. Submit meter readings on switch day so the final bill is accurate.
  5. Confirm the switch. Your new supplier contacts the old one. Supply continues uninterrupted.

You do not need to contact your old supplier to cancel. The new supplier handles the transfer.

5 Factors That Affect Your Electricity Cost Per kWh

  1. Region: standing charges and unit rates both move with the DNO area. Do not assume the national 26.32p average is your pence.
  2. Meter type: smart meters enable time-of-use tariffs. Standard meters lock you into flat-rate pricing.
  3. Payment method: monthly Direct Debit is the cap illustration used on this page. Prepay and standard credit have different typical figures (£1,678 and £1,861 dual-fuel in Oct–Dec 2026).
  4. Tariff type: a fixed unit rate only wins if the annual total beats the SVT illustration after standing charges and exit fees.
  5. Annual consumption: Ofgem’s current typical electricity figure used with the £1,723 dual-fuel headline is 2,500 kWh/year (not 2,700 or 2,900). Higher users should prioritise a low unit rate; lower users should watch the daily standing charge.

How to Reduce Your Electricity Consumption (and Lower Bills Further)

Switching to a cheaper supplier is the fastest way to save. Reducing consumption compounds those savings:

  • Shift flexible loads to off-peak hours on Economy 7 or a time-of-use tariff.
  • Switch to LED lighting. LED bulbs use far less electricity than incandescent bulbs.
  • Adjust boiler flow temperature (typically around 55–60°C) to cut heating kWh if you have a combi or system boiler on electricity-adjacent load — and draught-proof anyway.
  • Install draught-proofing. Reducing heat loss cuts demand.
  • Bleed radiators. Trapped air forces longer heating cycles.

For most households the right move is: get a written quote, compare it to 26.32p/kWh + 54.83p/day at your actual consumption, and ignore April 2026 product names. Confirm on Switch.

Frequently Asked Questions

What is a kWh?

A kWh (kilowatt-hour) is the standard unit for measuring electricity consumption. It equals the energy used by a 1,000-watt appliance running for 1 hour. For example, 1 kWh powers a 40-watt light bulb for 25 hours or charges a typical smartphone approximately 80 times.

What is the cheapest kWh electricity rate in the UK right now?

We do not invent a live cheapest p/kWh on this page. The SVT ceiling to beat for October–December 2026 is 26.32p/kWh plus 54.83p/day standing charge (national Direct Debit average, 0% VAT). Scottish Power Super Saver April 2026 Online at 16.57p/kWh and N Power Go Fix Apr 2026 at 19.34p/kWh were spring 2026 examples, not current picks. See Cheapest electricity-only deals UK.

How many kWh does a typical UK household use per year?

The TDCV used with Ofgem’s current typical dual-fuel Direct Debit headline (£1,723) is 2,500 kWh of electricity per year (and 9,500 kWh of gas). Older copy on this page used 2,700 kWh. Larger households (4+ people) often use 3,500 to 4,500 kWh/year; a single-person flat may use around 1,500 to 1,800 kWh/year.

What is a daily standing charge?

The daily standing charge is a fixed fee every day, regardless of how much electricity you use. It covers network and meter costs. The October–December 2026 national Direct Debit average is 54.83p/day (about £200/year) for electricity. Some no-standing-charge tariffs shift that cost into a higher unit rate instead.

What is the difference between kWh and kW?

A kW (kilowatt) measures the rate of power use, equal to 1,000 watts. A kWh (kilowatt-hour) measures total energy consumed over time. A 2kW electric heater running for 3 hours uses 6 kWh of electricity. Your bill charges you per kWh, not per kW.

What is the Ofgem price cap?

The Ofgem price cap limits the unit rate and standing charge suppliers can charge on standard variable tariffs. For 1 October–31 December 2026 the typical dual-fuel Direct Debit figure is £1,723/year (TDCV 2,500 / 9,500 kWh). Electricity is 26.32p/kWh + 54.83p/day. The April 2026 £1,641 figure is historical. Next print: 25 November 2026 for January–March 2027.

Is it worth switching to a fixed electricity tariff right now?

Yes, for many households still on an SVT, if a written quote at your kWh beats 26.32p/kWh + 54.83p/day after exit fees. Do not lock in because an April 2026 Super Saver was 10p below an old 26.60p SVT — that comparison is stale. Already-fixed households should check that 0% VAT on electricity is applied from 1 October 2026.

Can I switch electricity suppliers if I rent?

Yes. Ofgem confirms that tenants who pay energy bills directly have the right to switch suppliers. Your landlord cannot prevent a switch. Check your tenancy agreement for any default supplier clauses, but these cannot legally override your right to choose your own supplier.

How long does switching electricity suppliers take?

Switching takes 21 days on average. Suppliers signed up to the Energy Switch Guarantee must complete the process within 5 working days. Your supply continues uninterrupted throughout. There is a 14-day cooling-off period after signing your new contract during which you can cancel without penalty.

Does switching electricity suppliers affect my physical supply?

No. The electricity delivered to your home uses the same wires and infrastructure regardless of which supplier you choose. Only your billing and tariff change. The National Grid manages the physical supply network independently of commercial suppliers.
