Surge Protection
Surge Protection in Leeds & West Yorkshire
Power surges can destroy your valuable electronics in an instant. Whether caused by lightning strikes, grid switching, or large appliances cycling on and off, voltage spikes can damage TVs, computers, boilers, EV chargers, and smart home devices beyond repair. At Pennington Electrical Ltd, we install surge protection devices (SPDs) for homes and businesses across Leeds, Morley, and West Yorkshire.
Since the 18th Edition of BS 7671 (2018), surge protection is mandatory for certain building types and strongly recommended for all others. SPDs work by diverting excess voltage safely to earth before it reaches your sensitive equipment. A properly installed SPD can mean the difference between a brief power flicker and thousands of pounds in damaged appliances.
We install both Type 2 SPDs at the consumer unit for whole-property protection and Type 3 point-of-use SPDs for critical individual devices. For properties with solar panels, EV chargers, or expensive electronics, surge protection is an essential investment that pays for itself the first time it prevents damage.
Type 2 Consumer Unit SPDs
Type 2 SPDs are installed at the main distribution board and protect all circuits in the property from indirect lightning strikes and switching transients. We install compact, DIN-rail mounted SPDs inside your consumer unit that continuously monitor the supply voltage and activate in nanoseconds when a surge is detected. Every Type 2 SPD installation includes proper earthing verification and surge counter monitoring where specified.
Type 3 Point-of-Use Protection
Type 3 SPDs provide fine protection for individual sensitive devices such as computers, TVs, and audio equipment. They are installed adjacent to the equipment they protect and work alongside Type 2 devices to handle the residual voltage after the first line of defence. We install Type 3 protection for home offices, media rooms, and commercial IT equipment where maximum protection is needed.
Lightning & Transient Protection
Properties in exposed locations or with tall structures are at higher risk of direct lightning strikes. For these properties, we install Type 1 lightning current arrestors that can handle the massive energy of a direct strike, combined with Type 2 devices for comprehensive protection. We also assess and upgrade earthing systems where needed to ensure surge energy is safely dissipated.

FAQ
Common Questions About Surge Protection
Under BS 7671 18th Edition, surge protection is mandatory for certain buildings including those with critical systems, high public occupancy, and commercial installations. For domestic properties, it is strongly recommended.
A standard Type 2 SPD installed in a domestic consumer unit typically costs £150-£300 including the device, labour, and testing. Type 3 point-of-use protection is additional. We provide fixed-price quotes.
Type 2 SPDs protect against indirect strikes and switching transients. For direct lightning protection, Type 1 arrestors are needed. We assess your risk and recommend the appropriate protection level.
SPDs can last 5-10 years depending on how many surges they absorb. Quality SPDs have status indicators that show when replacement is needed. We include this in our maintenance checks.
