Best tariff for an all-electric home UK (June 2026)

All-electric homes — no mains gas — have higher electricity use, more standing charge sensitivity, and a real opportunity in time-of-use tariffs. The right tariff depends on whether you have storage heating, a heat pump, an EV, solar/battery, or just a flat with electric panels and an immersion heater.

All-electric home tariffs in June 2026 — at a glance

If you have storage heating or a heat pump that can pre-heat overnight, an Economy 7 or EV-style time-of-use tariff usually beats a flat single-rate. If your demand is spread through the day with no shift potential, a competitive flat tariff with low standing charge wins.

Quick checklist (May 2026):

  • Storage heating → Economy 7 is the historic fit; some EV-style TOU tariffs now beat it.
  • Heat pump with pre-heat capability → EV-style TOU often wins for overnight cycling.
  • EV + all-electric heating → strong case for EV TOU; model your overall mix.
  • No shiftable load → flat tariff with low standing charge.

Best tariff for an all-electric UK home in 2026

A clear, current overview to help you choose with confidence.

Three meter setups, three answers

Single-rate meter → flat tariff. Traditional Economy 7 meter → E7 tariff. SMETS2 smart meter → choice of E7, EV TOU, dynamic time-of-use, or flat.

Heat pump considerations

Heat pumps benefit from low overnight unit rates (pre-heat the thermal store overnight). Some suppliers offer heat-pump-specific tariffs in May 2026 with off-peak heat-pump windows.

Standing charge weight

All-electric homes often have a higher annual kWh than dual-fuel — but only on one meter. Standing charge is single, but the kWh is high, so unit rate matters more than for low-use homes.

Solar and battery owners

If you export to the grid, prioritise tariffs with strong export rates and time-of-use import. Some tariffs price exports at the prevailing day-ahead market price.

Compare like-for-like

Indicative May 2026 outcomes for a typical all-electric mid-terrace home using 6,500 kWh/yr (storage heating included).

What to compare Typical range (May 2026) Notes
Flat single-rate, 60p/day SC ~£1,750/yr Baseline.
Economy 7 (peak 30p / off-peak 16p) ~£1,500/yr If 40% of use is overnight.
EV-style TOU (peak 32p / off-peak 8p) ~£1,250/yr If 40%+ of use can shift overnight.
Heat pump TOU (where available) ~£1,200/yr If you have a heat pump with thermal store.
Cap-linked variable (no fix) ~£1,650/yr Moves with the quarterly cap.

How to choose the best tariff for an all-electric home (June 2026)

  1. 1. Map your loads

    Storage heating? Heat pump? EV? Immersion timer? Electric vehicle? Battery storage?

  2. 2. Check your meter

    Single-rate, traditional E7, or SMETS2 smart meter? Your meter limits the tariffs you can run.

  3. 3. Estimate your kWh

    Annual electricity use is your single most important number. Pull from last year's bill.

  4. 4. Decide your priority

    Lowest annual bill / certainty (fix) / greenest tariff / shiftable savings.

  5. 5. Compare and switch

    Use the form below to surface tariffs that fit your postcode, meter and usage.

Common pitfalls to avoid

The most frequent issues we see when households and businesses act on what looks like a good deal.

  • Choosing TOU without storage heating, heat pump, EV or shiftable load.
  • Forgetting the peak rate on a TOU tariff is higher than a flat rate.
  • Sticking with a traditional Economy 7 meter when SMETS2 unlocks cheaper TOU options.
  • Comparing only headline unit rates without including the standing charge.

Frequently asked questions

What's the cheapest tariff for an all-electric home in June 2026?

It depends on your kWh and whether you can shift load. EV-style TOU tariffs (overnight off-peak at 5–10p) often win for homes that can pre-heat or charge overnight. Flat tariffs with low standing charges win for homes with no shift potential.

Is Economy 7 still good for storage heating?

Yes — it's the original use case. Many storage heating homes will save by sticking with E7, but check whether an EV-style TOU tariff with a longer off-peak rate offers more.

Will I need a smart meter?

Yes for most modern TOU tariffs. Traditional Economy 7 still works with a legacy E7 meter.

Should I switch heat pump tariffs?

If you have a heat pump and a SMETS2 meter, look for heat-pump-specific tariffs. They typically price overnight kWh at a discount and assume a pre-heat strategy.

How much does the standing charge matter?

For all-electric homes, less than for low-usage flats — your kWh is high enough that the unit rate dominates. But it still matters for comparing tariffs at similar unit rates.

Can I get a fix for an all-electric home?

Yes — most fixed tariffs are available regardless of fuel mix. They lock in the unit rate and standing charge for the term.

Will solar panels change which tariff is cheapest?

Yes — if you export, look for tariffs with strong export rates (SEG or dynamic). Dynamic export tariffs can pay 15–30p/kWh at peak demand times.
