Electrical safety FAQs

Electrical safety means controlling risks from the use of electricity to prevent shock, burns, fires, explosions, and damage to people, property, and equipment. It involves using safe systems of work, suitable equipment, and correct procedures to minimise hazards.

Electrical safety is essential because electricity can cause serious injuries, fires, and fatalities if risks are not properly managed.

HSE guidance explains that electric shock, electrical burns, loss of muscle control, falls from height following a shock, and injuries from arcing or explosions are all common consequences of electrical incidents.

Electrical safety rules are essential practices to prevent electric shock, burns, fires, explosions, and equipment damage. They are guided by key UK legislation:

• Electricity at Work Regulations 1989, which require electrical systems to be constructed, maintained, and used in a way that prevents danger, and mandate safe isolation, competent persons, and suitable precautions when working on or near electricity.
• Health and Safety at Work etc. Act 1974, which places a general duty on employers to ensure the safety of employees and others, including controlling electrical risks.
• Provision and Use of Work Equipment Regulations 1998 (PUWER), which require electrical equipment to be safe, suitable, and properly maintained.
• Management of Health and Safety at Work Regulations 1999, which require employers to assess and manage risks from electricity.

Together, these laws shape common electrical safety rules such as isolating and locking-off circuits before work, using competent persons, maintaining equipment, and ensuring safe systems of work.

Safety precautions when using electricity include:

• Keeping electrical equipment in good condition and reporting faults immediately.
• Avoiding contact with water and using equipment only in suitable environments.
• Not overloading sockets or extension leads.
• Ensuring circuits are protected by the correct fuses and RCDs.
• Switching off and unplugging equipment before cleaning or maintenance.
• Using only competent people for electrical work and following safe isolation procedures where relevant.

These precautions help prevent shocks, burns, fires, and equipment damage.

When using electrical appliances, key safety rules include:

• Check for damage before use, including cracked plugs, exposed wires, or loose connections.
• Use appliances only as intended and follow the manufacturer’s instructions.
• Avoid overloading sockets or using unsafe multi-adaptors.
• Keep appliances dry and away from water unless specifically designed for wet environments.
• Ensure proper ventilation for equipment that generates heat.
• Switch off and unplug appliances before cleaning, adjusting, or when not in use.
• Use only approved, well-maintained equipment, and report any faults immediately.
• Ensure portable appliances are appropriately inspected and tested (e.g., PAT testing) where required.

Following these rules helps prevent electric shock, overheating, and fire hazards.

Five key electrical safety tips are:

1. Check equipment for damage before use and don’t use anything with exposed wires or loose parts.
2. Avoid overloading sockets and use extension leads safely.
3. Keep electricity and water separate unless equipment is designed for wet areas.
4. Unplug appliances when not in use or before cleaning or maintenance.
5. Use RCD protection to reduce the risk of electric shock during portable or outdoor use.

These tips help prevent shocks, burns, and fire hazards.

Electrical safety devices are components designed to prevent electric shock, fires, and equipment damage by interrupting or limiting faulty electrical currents. Common examples include:

• Fuses – melt to break the circuit if too much current flows.
• Circuit breakers – automatically switch off the supply when an overload or short circuit occurs.
• Residual Current Devices (RCDs) – quickly disconnect the circuit if electricity leaks to earth, reducing the risk of electric shock.
• Surge protection devices – protect equipment from voltage spikes.
• Insulation and enclosures – prevent accidental contact with live parts.

These devices help keep electrical systems safe and compliant with UK regulations.

Common PPE for electrical safety includes insulated gloves, safety footwear with anti-static or insulating properties, flame-resistant clothing, eye protection, and insulated tools. The exact PPE needed depends on the task and the level of electrical risk, particularly when working on or near energised equipment.

LOTO (Lockout/Tagout) is a safety procedure used to ensure electrical equipment is fully isolated before work begins. It involves switching off the power, locking the isolation point with a physical lock, and attaching a tag identifying who applied it. This prevents the equipment from being re-energised accidentally, protecting workers from electric shock, burns, or unexpected machinery movement during maintenance or repair.

Our LOTO Training (Lock Out/Tag Out) raises awareness of how to manage hazardous energy and prevent serious injuries caused by unexpected machinery start-up, supporting compliance with the Health and Safety at Work etc. Act 1974 and PUWER 1998.

Landlords in England must have a valid Electrical Installation Condition Report (EICR) for rented properties under the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020.

For workplaces, while there is no specific law requiring a certificate, employers must ensure electrical systems are safe and properly maintained under the Electricity at Work Regulations 1989, and an EICR provides evidence of compliance.

A landlord electrical safety certificate refers to an Electrical Installation Condition Report (EICR), which confirms the condition and safety of the fixed electrical installation.

Under the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020, landlords must have an EICR at least every five years and provide it to tenants and the local authority when required.

An electrical safety check involves a competent person inspecting and testing the fixed electrical installation to assess whether it is safe and compliant. This includes checking the condition of wiring, sockets, switches, consumer units, earthing and bonding, and looking for deterioration, damage, overloading, or other hazards.

Testing is then carried out to verify that circuits and protective devices operate correctly. The findings are recorded in an Electrical Installation Condition Report (EICR).

An electrical safety check usually takes between 1 and 4 hours, depending on the size of the property or premises, the number of circuits, and the condition of the installation. Larger or more complex systems may take longer, especially if faults are found that require further investigation.

Electrical safety checks should be carried out at intervals appropriate to the type and condition of the installation.

In rented properties in England, landlords must have an Electrical Installation Condition Report (EICR) at least every five years.

In workplaces, the Electricity at Work Regulations 1989 require systems to be maintained safely, and many organisations use periodic inspection and testing every three to five years as a benchmark, adjusted based on risk, usage, and previous inspection findings.

An electrical safety certificate (EICR) usually lasts up to five years, although the exact interval is determined by the inspector based on the condition of the installation.

For rented properties in England, landlords are legally required to have a new EICR at least every five years. In other settings, shorter intervals may be recommended where higher risks or signs of deterioration are identified.

You can usually find your electrical safety certificate (EICR) online by checking the systems used by the organisation that arranged the inspection:

• Private rented properties: Your landlord or letting agent should provide a digital copy. Some use online portals where documents are stored for tenants.
• Workplaces or commercial premises: The certificate is often held in a digital compliance system, facilities management portal, or the contractor’s online reporting platform.
• If you can’t find it: Contact the electrician or company that carried out the inspection, as they will have a record and can resend the certificate.

There is no central national database for electrical safety certificates, so it must be retrieved from whoever commissioned or carried out the inspection.

No, PAT testing itself is not a strict legal requirement.

UK law does not specifically say you must carry out PAT testing. However, under the Electricity at Work Regulations 1989 and the Provision and Use of Work Equipment Regulations (PUWER), employers have a legal duty to ensure electrical equipment is safe and does not present a risk.

PAT testing is one recognised way of meeting this duty, but it is not the only option. Safety can also be demonstrated through a combination of risk assessment, regular visual inspections, user checks, maintenance, and testing where appropriate.

The level of testing required depends on the type of equipment, how it is used, and the environment, as set out in guidance from the Health and Safety Executive (HSE).

No, new electrical appliances do not usually need to be PAT tested when they are first put into use.

Brand-new equipment should already meet UK safety standards and normally only needs a visual check to confirm it is undamaged and suitable for use. Formal PAT testing may be required later, depending on the risk, how the equipment is used, and the environment it is used in.

Guidance from the Health and Safety Executive (HSE) makes clear that inspection and testing should be proportionate, based on risk, rather than automatic or routine testing of new items.

An electrical safety audit is a structured assessment of how effectively an organisation manages electrical risks. It involves evaluating the condition of electrical installations, the suitability and maintenance of equipment, the competence of personnel, safe systems of work, and compliance with legislation such as the Electricity at Work Regulations 1989.

The audit highlights gaps, recommended actions, and measures needed to ensure electrical systems are operated and maintained safely.

Electrical safety training should be provided often enough to ensure employees remain competent, with refresher training scheduled according to risk, job role, and any changes to equipment, procedures, or legislation.

Many organisations use an annual or biannual refresher as a benchmark, but higher-risk roles may require more frequent updates.

Our IOSH Approved, CPD Certified Electrical Safety Training helps employees recognise hazards, follow safe systems of work, and support compliance with the Electricity at Work Regulations 1989.

Warning signs of a faulty electrical system or appliance include plugs or sockets that feel hot to the touch, persistent flickering or dimming lights, and frequent tripping of circuit breakers or blowing of fuses.

Other red flags are buzzing or crackling sounds, visible scorch marks, loose or damaged cables, and unusual smells, such as a fishy or burning plastic odour, which can indicate overheating or melting insulation.

If you notice any of these signs, stop using the appliance, isolate the power if it is safe to do so, and report it or have it checked by a competent person immediately.

Arcing is when electricity jumps through the air between two conductors instead of flowing smoothly through a connection. It usually happens because of loose connections, damaged cables, worn plugs, or faulty switches.

Arcing is dangerous because it produces very high temperatures, which can ignite surrounding materials, melt insulation, and start electrical fires.

While a tiny spark can occur briefly when plugging something in, repeated, visible sparks, crackling noises, burning smells, or scorch marks are warning signs of dangerous arcing and should be checked immediately by a competent person.

When using electricity outdoors, extra precautions are required because water, moisture, and physical damage greatly increase the risk of electric shock.

Outdoor electrical equipment must be designed for external use, meaning it has a suitable IP (Ingress Protection) rating and weatherproof casing. Residual Current Devices (RCDs) must be used to quickly cut off power if a fault occurs.

Equipment, plugs, and leads should be kept dry, undamaged, and raised off the ground where possible, and cables should be routed to prevent trips or damage.

You should never use indoor appliances outdoors, avoid electrical work in wet or severe weather, and always isolate the power supply before plugging in, unplugging, or adjusting equipment.

These requirements reflect guidance from the Health and Safety Executive (HSE) and are essential to reduce the risk of serious injury or fire.

Extension leads should be used carefully and only when necessary to reduce the risk of overheating, electric shock, and fire.

Key safety rules include:

• Never overload extension leads. Check the maximum load and avoid running high-power appliances together.
• Do not “daisy-chain” extension leads by plugging one into another, as this is a common cause of fires.
• Fully unwind cable reels or drum extensions before use to prevent heat build-up.
• Use the right lead for the environment, including outdoor-rated leads with suitable IP ratings where required.
• Check for damage to plugs, sockets, and cables before use and remove faulty leads immediately.
• Route cables safely to avoid trips, crushing, or contact with heat or water.

Following this approach aligns with guidance from the Health and Safety Executive (HSE) and helps keep electrical equipment safe in both workplace and home environments.

If someone is receiving an electric shock, do not touch them until the power source has been safely isolated.

First, switch off the electricity at the mains or unplug the equipment if it is safe to do so. If you cannot isolate the power, use a dry, non-conductive object (such as a wooden broom handle or plastic item) to separate the person from the electrical source while standing on a dry surface.

Once the power is off, call emergency services immediately. If the person is unresponsive or not breathing, begin first aid or CPR only if you are trained. Even if the person appears to recover, they should still receive medical attention, as electrical injuries can cause internal damage.

These steps reflect essential safety guidance from the Health and Safety Executive (HSE) and are critical to prevent further injury or death.

For an electrical fire, you should use a CO₂ (carbon dioxide) or dry powder fire extinguisher.

These extinguishers are suitable because they do not conduct electricity and can safely tackle fires involving live electrical equipment. Never use water or foam extinguishers on an electrical fire, as they can cause electric shock and make the situation far more dangerous.

If it is safe to do so, isolate the power supply first. If the fire cannot be controlled quickly, evacuate the area and call the fire service.

In the UK, you can carry out minor, low-risk electrical work yourself at home, provided you are competent and follow safety requirements.

Work you can usually do includes replacing switches, sockets, light fittings, and ceiling roses, changing fuses, and carrying out like-for-like repairs on existing circuits. You must not carry out higher-risk work, such as installing new circuits, work in bathrooms or other “special locations”, or significant alterations to existing wiring, unless the work is notified and certified or carried out by a registered electrician.

These restrictions come from Part P of the Building Regulations, which aims to prevent fire and electric shock. If you are unsure whether work is notifiable or safe to do yourself, it’s best to use a qualified electrician.

A Competent Person in electrical safety is someone who has the appropriate knowledge, training, skills, and experience to carry out electrical work safely and correctly.

This means they understand the risks involved, can identify hazards, know the relevant laws and standards, and are able to take proper precautions to prevent electric shock, fire, or injury. Competence includes qualifications, practical experience and the ability to recognise the limits of one’s own capability.

Under UK health and safety law, employers must ensure that electrical work is carried out only by competent people, as set out in guidance from the Health and Safety Executive (HSE).
