Appliance Running Costs
See how much your appliances cost to run at current Q2 2026 rates (24.67p/kWh)
💡 Key Insight
The single biggest electricity user in most homes is the appliance that combines high wattage with long hours. An electric panel heater used 4 hours a day costs more than a fridge-freezer running 24/7 all year. A 10-minute electric shower for a family of 4 costs ~£140 a year. An EV charged 4 nights a week at home costs ~£615 a year on the standard cap, but only ~£175 on a time-of-use EV tariff with overnight rates around 7p/kWh.

Economy 7 and Time-of-Use Tariffs
Save money with off-peak electricity
Economy 7 tariffs split electricity into peak and cheaper off-peak rates (typically 7 hours overnight). They make financial sense if you can shift 30%+ of your usage to night hours—ideal for households with storage heaters, immersion water heating, or EV charging.
As of May 2026, competitive Economy 7 night rates include:
- ScottishPower EV Saver: 3.69p/kWh night, 32.43p/kWh day
- Utility Warehouse Fixed Saver: 6.92p/kWh night, 35.25p/kWh day
- British Gas Fixed Tariff Dec 26: 9.67p/kWh night, 27.61p/kWh day
(Rates as of 14 May 2026. Verify on Citizens Advice ↗ before switching)

Solar Panels, Battery Storage & Heat Pumps
Generate, store, or shift your electricity usage
The economics of home energy generation shifted dramatically in 2026. Solar panel costs fell to £6,000-£8,000for a typical 4kW system—the most compelling solar payback in UK history.
☀️ Solar PV (4kW)
- Generates ~3,400 kWh/yr
- Saves £700-900/yr
- Payback: 8-11 years
🔋 Battery (9.5kWh)
- Stores a day's electricity
- Adds £400-550/yr saving
- Best with time-of-use tariff
- SEG: 0.2p/kWh export
🚗 EV Charging
- ~2,500 kWh/yr
- Standard: £615/yr
- EV tariff: £175/yr
- 7p/kWh overnight rates
Smart Meters
Enable time-of-use tariffs and accurate billing
A smart meter is the infrastructure that enables time-of-use tariffs. Without one, you can't access Economy 7, EV tariffs, or Smart Export Guarantee for solar generation.
What a smart meter does:
- Reports usage every 30 minutes (with permission)
- Shows real-time consumption in £ and kWh
- Enables time-of-use tariffs
- Removes estimated bills
What it doesn't do:
- Track individual appliance usage
- Automatically save money
- Cut supply for non-payment (without safeguards)
To get one: contact your supplier. Installation is free. ~90% of GB homes have smart meters in 2026. Smart Energy GB ↗
How to Read Your Meter
Step-by-step guide to reading your electricity meter
Reading your meter helps you track actual usage, spot billing errors, and avoid estimated bills. Most homes have either digital or dial meters.
Digital Meter
How to read: Write down all numbers from left to right. Ignore any numbers after the decimal point or in red.
Dial Meter
How to read: Read dials left to right. When a pointer is between two numbers, record the lower number. Note that dials alternate clockwise/anticlockwise.
Tips for Accurate Readings
- Take a photo of your meter reading for your records
- Submit readings monthly to avoid estimated bills
- Compare readings with your bill to spot errors
- If you have Economy 7, you'll have two readings (day and night)

Q2 2026 Price Cap Analysis
Understanding the April 2026 price cap changes
The Q2 2026 electricity price cap of £1,641 represents a welcome 7% decrease from Q1's £1,768. This £127 annual saving for typical households reflects lower wholesale energy costs and improved grid stability.
At 24.67p per kWh, electricity remains expensive compared to historical norms. The cap is still 40% higher than pre-crisis 2021 levels. Standing charges at 57.21p daily continue to penalize low users—you'll pay £209yearly just to stay connected.
Q3 2026 Outlook
Forecasters expect the Q3 cap (July-September) to rise to £1861, a 13.4% increase driven by Middle East wholesale disruption affecting UK gas prices. If you're risk-averse, fixing now below the cap could hedge against Q3 rises.
The medium-term trajectory remains uncertain. Geopolitical tensions, renewable rollout pace, and grid upgrade costs all influence future caps. Most analysts expect prices to remain elevated through 2027, with gradual normalization by 2028.
Frequently Asked Questions
1. How do I find my kWh usage?
Check your latest electricity bill—it shows kWh used in the billing period. For a more accurate estimate, take meter readings 30 days apart and subtract the lower from the higher. Smart meter users can see daily and monthly kWh in the in-home display or supplier app.
2. What is the current UK electricity unit rate?
Under the Ofgem Q2 2026 price cap (1 April – 30 June 2026), the GB average electricity unit rate is 24.67p per kWh with a daily standing charge of 57.21p. Your exact rate depends on your region. (Ofgem ↗)
3. Why is electricity so much more expensive than gas?
At Q2 2026 cap rates, electricity costs 4.3× more per kWh than gas (24.67p vs 5.74p). This reflects generation costs, transmission losses, and grid balancing. Heat pumps need COP 3.5+ to match gas boiler running costs.
4. Should I fix my electricity tariff or stay on the cap?
With Q3 2026 forecast at £1861 (+13.4%) due to wholesale disruption, fixing now hedges against rises. Current 12-month fixes are 3-5% below cap. Check Citizens Advice ↗ for whole-of-market comparison.
5. What's a standing charge, and why is it so high?
The standing charge (57.21p/day GB average) covers network maintenance and connection costs. It varies regionally from 57.21p (London) to 70.78p (North Wales & Mersey). You pay £163-258/yr just to be connected, before any usage.
6. What's Economy 7 and is it worth it?
Economy 7 splits electricity into day/night rates with cheaper overnight hours. Worth it if you shift 30%+ usage to night (storage heaters, EV charging, immersion heating). Most households save more on single-rate tariffs.
7. How accurate is this calculator?
Within 5-10% for most households. Uses Ofgem Q2 2026 cap rates, applies regional variations, and adjusts for payment method. Based on formula: (kWh × unit_rate) + (365 × standing_charge).
8. Can I switch supplier?
Yes, switching is free and takes 5 working days. UseCitizens Advice ↗ for unbiased comparison. Commercial sites only show tariffs they earn commission from.
