Tips for safer electrical work during home renovation

However, safety and compliance with regulations must always come first. While there are certain tasks you can handle on your own, electrical work is one area where professional expertise is often essential.

What you can do yourself

Electricity is part of everyday life, which can make its dangers easy to overlook. When you start working directly with electrical installations, the level of risk increases significantly.

Complex electrical tasks should always be carried out by a qualified electrician. That said, there are simpler jobs that homeowners can complete safely, provided basic precautions are followed.

Examples of tasks you may be able to do yourself include:

• installing garden lighting
  
• fitting pumps for garden ponds
  
• installing battery-powered smoke alarms
  
• setting up small solar-powered lights
  
• replacing light bulbs, ensuring the correct wattage is used
  
• preparing openings for portable air conditioning units without connecting them to the power supply
  
• positioning an electric oven without wiring it to the mains
  
• replacing a drive belt on a washing machine
  

Tasks that should be left to professionals

If the work involves designing, installing, testing, maintaining or altering electrical systems, a qualified electrician should always be hired.

Poorly executed electrical work can cause overheating, short circuits and, in severe cases, fires. Even minor mistakes can have serious consequences for both property and personal safety.

Extra caution is required in areas where electricity and water are close together, such as bathrooms, kitchens, outdoor spaces and around pools. These areas are subject to stricter safety regulations and should always be handled by professionals.

Tasks that should be carried out by a professional electrician include:

• replacing sockets and light switches
  
• installing lighting combined with ceiling fans
  
• fitting consumer units and additional circuits
  
• relocating power points
  
• repairing and testing electrical appliances
  
• replacing plugs and power leads
  

Key safety points during renovation

Regardless of the scale of the renovation, certain safety measures should always be observed:

• do not bend or stretch cables, and route them to avoid trip hazards
  
• only use extension leads outdoors if they are designed for external use
  
• familiarise yourself with the consumer unit and check whether a tripped breaker is the cause of a power issue
  
• plan work that requires power to be switched off at times that minimise disruption
  

For properties over 50 years old, a full electrical rewire is often recommended. Older wiring may not be able to handle modern electrical loads, and degraded insulation significantly increases the risk of fire.

When fitting ceiling lights, always use a stable ladder. Never stand on the top rung and make sure the ladder is securely positioned. For outdoor work, ladders must be properly supported and placed on stable ground.

Keeping family and surroundings safe

During renovation, take extra care if you have children or pets in the home. Exposed cables, tools and electrical equipment can pose serious risks.

In older properties, renovation work can release dust or mould containing harmful particles. These can spread through the air and affect health if inhaled. Proper ventilation helps reduce both health risks and the likelihood of electrical overheating or fire.

Our recommendation

This guide cannot cover every possible situation, but following these principles can significantly reduce risk during renovation. Before starting, it is wise to familiarise yourself with typical building and electrical labour costs so you can plan your budget realistically.

If you are ever unsure about working with electricity, the safest option is always to hire a professional. Saving money should never come at the expense of safety.
