Older properties in London often come with a unique charm—Victorian fireplaces, Edwardian ceilings, or Georgian brickwork. However, behind the heritage façade lurks one of the most pressing safety risks: outdated electrical appliances and systems. Fires linked to electrical devices in older homes remain a leading concern for London’s fire services.

The main causes can be traced back to ageing wiring and lack of modern protective systems. Many older homes still rely on decades-old wiring that was never designed for today’s heavy electrical loads. Overloaded sockets, cheap extension leads, and makeshift fixes add to the problem, placing extra stress on fragile circuits.

Another major cause is the deterioration of old appliances themselves. Fridges, washing machines, or heaters that have been in service far beyond their recommended lifespan often fail in ways that can spark fires. Insulation breaks down, internal components loosen, and switches can arc. Add dust build-up and lack of regular maintenance, and the risk multiplies.

Poor DIY work is another hidden danger. Homeowners attempting quick repairs without professional expertise often create unsafe connections. This is especially common in houses that have been modified multiple times over the years without proper inspections.

Preventing fires starts with professional fault finding and inspections, such as an Electrical Installation Condition Report (EICR). Upgrading consumer units to modern RCD-protected boards and rewiring high-risk areas dramatically lowers fire risks. Replacing tired appliances and avoiding overloaded sockets are simple yet effective measures.

Ultimately, the safest approach is to respect the heritage beauty of London’s old homes while ensuring their electrics meet 21st-century safety standards.
