Power surges Tunbridge Wells homeowners experience can damage electronics, shorten appliance lifespan and increase fire risk. Learn what causes them and how to protect your home.
A power surge is a sudden spike in electrical voltage that travels through your wiring. While small fluctuations happen every day, larger surges can permanently damage appliances and internal wiring.
Surge protectors work by diverting excess voltage safely to earth, helping prevent damage to connected devices:

What causes power surges in UK homes?
Several everyday situations can cause voltage spikes inside domestic electrical systems:
- Electrical storms: Lightning strikes near power lines can send large surges through the grid.
- Grid switching: Utility companies regularly rebalance supply, which can cause brief voltage changes.
- Large appliances cycling: Washing machines, ovens and refrigerators switching on and off can create internal surges.
- Faulty wiring or poor earthing: Older installations may not handle voltage changes safely.

Signs your home may be experiencing power surges
Power surges are often brief, but repeated events leave clues:
- Lights flicker or dim unexpectedly
- Sockets or plugs feel warm
- Appliances fail earlier than expected
- Consumer unit trips without a clear cause
These symptoms may also indicate wider electrical issues, so professional inspection is recommended.
Why power surges damage appliances
Modern appliances contain sensitive circuit boards that cannot tolerate sudden voltage spikes. Even small repeated surges slowly degrade components, leading to premature failure.
This is why many UK wiring regulations now recommend surge protection devices in consumer units:

How to protect your home from electrical surges
You can reduce surge risks by:
- Installing surge protection devices (SPDs) in your consumer unit
- Using quality surge-protected extension leads for sensitive electronics
- Avoiding overloaded sockets
- Ensuring your property has correct earthing and bonding
A qualified electrician can assess whether your consumer unit supports SPDs and whether upgrades are needed.
