High Electricity Bills?
Unexplained high bills could indicate faulty appliances, electrical problems, or hidden energy drains. We can help you find and fix them.

Why Is My Electricity Bill So High?
The biggest hidden drain we find in Devon homes is the immersion heater left on constant. A 3kW immersion running 24/7 costs roughly £30/week – over £1,500/year – heating water you're not using. If your hot water cylinder feels warm all day even when you're not running taps, check whether the immersion is on a timer or the thermostat has failed in the 'on' position.
The second most common waste is old halogen downlights. A kitchen with 12 halogen GU10 spotlights at 50W each burns 600W every hour they're on – about 15p/hour. Replace them with 5W LEDs and that drops to 60W total, saving over £100/year in a kitchen alone. We carry compatible LED replacements on our vans and can swap a full kitchen in under an hour.
Less obvious but more concerning is current leakage to earth through degraded wiring. If cable insulation has broken down, a small but continuous current flows to earth – you're paying for electricity that's literally disappearing into the ground. An EICR will measure insulation resistance on every circuit and flag any that are leaking. We've found properties wasting 500W+ continuously through insulation faults – that's £500/year before you've even switched a light on.
Quick Energy Saving Tips
- Switch all lighting to LED – saves up to £75/year
- Use a plug-in energy monitor to identify power-hungry appliances
- Turn off devices at the wall rather than leaving on standby
- Set your immersion heater on a timer rather than constant
- Consider smart heating controls for electric radiators
- Have an EICR to check for electrical faults causing waste
Common Causes of High Bills
Faulty Appliances
Malfunctioning appliances, especially fridges, freezers, and immersion heaters, can consume excessive power without you realising.
Poor Insulation & Electric Heating
Electric heaters working overtime due to heat loss can dramatically increase bills, especially in older properties.
Standby Power Drain
Devices left on standby (TVs, computers, chargers) can add up to 10% to your electricity bill – often called 'phantom load'.
Outdated Lighting
Old halogen spotlights and incandescent bulbs use 5-10x more energy than modern LED alternatives.
Electrical Fault / Current Leakage
Damaged wiring or faulty insulation can cause current to leak to earth, wasting electricity and creating safety hazards.
Meter Problems
Rarely, faulty meters can record incorrect readings. Smart meters can also occasionally malfunction.
Frequently Asked Questions
Why is my electricity bill so high?
High electricity bills can result from faulty appliances, inefficient heating, standby power drain, outdated lighting, or electrical faults causing current leakage. A professional energy audit can identify the culprits and recommend cost-effective solutions.
Can electrical faults increase electricity bills?
Yes, damaged wiring or poor insulation can cause current to leak to earth, wasting electricity. An EICR (Electrical Installation Condition Report) can detect these faults and identify areas needing repair, potentially saving you money long-term.
How can an electrician help reduce electricity bills?
Electricians can identify and repair electrical faults, upgrade to LED lighting (saving up to £75/year), install smart controls for heating, and conduct energy audits to find where your electricity is being wasted.

Frequently Asked Questions
Why is my electricity bill so high?
Common causes include old inefficient appliances, immersion heaters left on, poor insulation causing heating to work harder, faulty thermostats, or a wiring fault causing earth leakage current that your meter records.
Can an electrician help reduce my electricity bills?
Yes. We can identify energy-wasting issues like faulty immersion heaters, inefficient lighting, or earth leakage faults. LED lighting upgrades alone can cut lighting costs by 60-80%.
How much does an energy audit cost?
A basic electrical energy assessment costs from £80 plus VAT. This includes checking for earth leakage faults, identifying inefficient circuits, and recommending cost-saving improvements like LED upgrades and smart controls.
Could faulty wiring be causing high electricity bills?
Yes. Earth leakage faults cause current to flow to earth through your meter, which you pay for. Degraded insulation in older wiring is a common cause. An insulation resistance test can identify this problem.
