Why Choose Us?

Why Your Property Needs Surge Protection Devices

You might not realise that everyday power surges can cause cumulative damage to the sensitive microprocessors inside your household appliances. While many think of lightning as the primary threat, smaller, frequent surges from the national grid or the switching of heavy electrical motors nearby are often the silent culprit behind failing electronics. By installing a Surge Protection Device, known as an SPD, we help divert these dangerous spikes away from your appliances. This simple, life-saving addition significantly increases the longevity of your high-value electrical assets.

Frequently Asked Questions About Power Surge Safety

Is a surge protector the same as a standard extension lead? No, the plug-in versions you find in shops offer limited protection compared to a whole-home SPD fitted at the consumer unit. Can I install an SPD in an older property? Yes, though we will first assess your wiring and earthing to ensure your system can support the upgrade safely. Does my insurance require surge protection? Many insurance providers now strongly recommend or require compliant surge protection to cover damage to electronic equipment; we provide the necessary documentation to verify your installation meets these safety requirements.
