Vulcanised Rubber Insulated (VRI) Cables: An Invisible Danger in UK Homes

Broken down insulation of VRI cable

Vulcanised Rubber Insulated (VRI) cables were widely installed in UK homes from approximately 1910 to the late 1950s. While modern electrical installations use safer and more durable insulation materials such as PVC, many properties across the UK still contain aging VRI wiring, silently posing severe hazards.

Why is VRI Cabling Dangerous?

Over decades, VRI cable insulation deteriorates naturally. Rubber becomes dry, brittle, and ultimately crumbles away, leaving exposed copper conductors. This deterioration significantly increases the risks of:

• Electrical Fires: Brittle insulation and exposed conductors can cause short circuits, leading to dangerous electrical fires.

• Electric Shocks and Electrocution: Without proper insulation, exposed wiring poses direct risks of severe electric shocks.

• Damage to Electrical Equipment: Short circuits resulting from faulty insulation can permanently damage household appliances and other equipment.

Facts You Should Know:

• According to Electrical Safety First, outdated wiring remains one of the primary causes of household fires in the UK.

• Industry experts strongly recommend regular Electrical Installation Condition Reports (EICRs) to identify and rectify dangerous wiring conditions.

Have You Checked Your Wiring?

Many homeowners are unaware that their properties still contain hazardous VRI wiring. A professional inspection can reveal these hidden dangers and provide peace of mind.

If your home was built or last rewired before the 1960s, it’s essential to have your wiring inspected by a qualified electrician. Ignoring deteriorating wiring could lead to tragic consequences.
