SPD is known as Surge Protection Device are used to protect the electrical installation, which consists of the Consumer Unit (Fusebox), Wiring System and Appliances, from electrical power surges known as transient overvoltages. Transient overvoltages are short duration, high magnitude voltages peaks with fast rising edges, commonly referred to as Lightning Surges.
SPD is now built-in Electric Vehicle Chargers, Solar Generation Systems and many more. Your home appliances and conductors (wires) in walls, floors and ceilings are part of your Electrical Wiring System of your Home or Business.
SPD protects data on your computers, laptops and other crucial or life saving devices. This little device keeps your electronics from getting damaged in a power surge, usually storm related, by redirecting unexpected increases in voltage away from delicate equipment. Even without a storm, smaller, less noticeable power spikes can shorten the life of your devices.
To protect electronic devices from damage: SPDs can help to prevent damage to electronic devices from power surges, which can be caused by a variety of factors, such as lightning strikes, power outages, and other electrical disturbances.
To protect the electrical installation: SPDs can also help to protect the electrical installation from damage caused by power surges. This is important because damage to the electrical installation can lead to a fire or other safety hazard.
To comply with regulations: The IET Wiring Regulations (2019) advise that SPDs should be installed in all domestic and non-domestic premises. This is to help to protect people and property from the risks associated with power surges.
There are a number of different types of SPDs available, so it is important to choose the right type for your needs. SPDs can be installed in a variety of ways, so it is also important to consult with a qualified electrician to ensure that they are installed correctly.
Here are some of the benefits of using a surge protection device in the UK:
Protects your electronic devices from power surges. A surge protector can help to prevent damage to your electronic devices from power surges, which can be caused by lightning strikes, power outages, and other electrical disturbances.
Extends the life of your electronic devices. By protecting your electronic devices from power surges, a surge protector can help to extend their lifespan.
Saves you money. By preventing damage to your electronic devices, a surge protector can save you money on repairs and replacements.
If you are concerned about the safety of your electronic devices, or if you want to extend their lifespan, a surge protector is a worthwhile investment.
The consequences of a surge
Without adequate protection the greatest consequence is a risk to human life, particularly in circumstances where medical equipment is involved and could be damaged. Secondly, there is the potential downtime in production e.g. in a workshop, retail outlet or office.
Type 1 SPD
The Type 1 SPD is recommended in the specific case of service-sector and industrial buildings, protected by a lightning protection system or a meshed cage.It protects electrical installations against direct lightning strokes. It can discharge the back-current from lightning spreading from the earth conductor to the network conductors.
Type 2 SPD
The Type 2 SPD is the main protection system for all low voltage electrical installations. Installed in each electrical switchboard, it prevents the spread of overvoltage's in the electrical installations and protects the loads.
Type 3 SPD
These SPDs have a low discharge capacity. They must therefore mandatorily be installed as a supplement to Type 2 SPD and in the vicinity of sensitive loads.

You must check if your electrician is qualified and also registered to carry out Domestic work under Part P and he must be registered with one of the 5 main organization, which you can check on the Competent Person scheme here.
