Surge ProtectionSPD Installation & 18th Edition Compliance

Surge protection devices (SPDs) protect your electrical equipment from voltage spikes caused by lightning strikes, power grid switching, or faulty appliances. Without protection, surges can damage or destroy expensive electronics, computers, and appliances instantly. We install surge protection devices across Bedfordshire — including Bedford, Luton, Dunstable, Leighton Buzzard, Biggleswade, and all surrounding areas — to protect your home and business.

Surges are caused by lightning strikes, power grid switching, large appliances turning on/off, faulty wiring, or utility company equipment failures. Even small surges over time can degrade electronics, shortening their lifespan significantly. Bedfordshire properties in rural areas — such as those near Ampthill, Sandy, and Biggleswade — can be particularly vulnerable to lightning-induced surges.

Primary protection should be installed at the consumer unit to protect the entire property. Secondary protection at individual sockets protects sensitive equipment like computers, TVs, and home entertainment systems for comprehensive coverage. We install both types of surge protection across Bedfordshire, ensuring your property has the right level of protection for your needs.

The 18th Edition Wiring Regulations (BS 7671:2018) require surge protection in most new installations and major alterations. It's mandatory where consequences of equipment failure could be serious or where equipment is particularly sensitive to surges. All new consumer unit installations we carry out across Bedfordshire include surge protection as standard to comply with current regulations.

Surge protection devices typically last 5–10 years depending on the number and severity of surges they absorb. Many SPDs have indicator lights showing when they need replacement. Regular inspection ensures continued protection. We check surge protection devices during EICR inspections across Bedfordshire and replace them when required.

While surge protection significantly reduces risk, no system offers 100% protection against direct lightning strikes. However, properly installed SPDs protect against 99% of common surges, saving thousands in equipment replacement costs. For Bedfordshire businesses with expensive IT equipment or machinery, surge protection is an essential investment.

Type 1 SPDs are installed at the main distribution board and protect against direct lightning strikes. Type 2 SPDs are installed at the consumer unit and protect against indirect surges from the power network. Type 3 SPDs are installed at individual sockets for point-of-use protection. Most Bedfordshire domestic properties require Type 2 protection at the consumer unit, while commercial properties may need Type 1 and Type 2 combined.

Surge protection device installation in Bedfordshire typically costs £150–£350 for a domestic property, depending on the type of SPD and whether it's being installed as part of a consumer unit upgrade or as a standalone addition.
