Electrical testing helps make sure your home is safe. It checks whether your wiring and systems are working properly. Both homeowners and landlords need to understand how often to carry out inspections and why they are essential.

Why Does Your Home Need Electrical Testing?
Over time, electrical systems can wear down or become damaged. You may not notice problems until something goes wrong. Faulty wiring, damaged sockets, or overloaded circuits can lead to electric shocks or fires.
An inspection helps check the condition of your system and ensure your property meets safety standards. This protects your home and family. For landlords, these checks are also a legal requirement to make sure tenants live in a safe environment. Even if you own your home, regular testing is a smart way to prevent future repairs and help keep your property safe.
What Gets Tested in a House?
A qualified electrician will inspect the main parts of your home’s electrical system. This includes the fuse board, sockets, switches, light fittings, and fixed wiring. They will check for signs of wear, overheating, or damage that could lead to faults.
The electrician will also test safety devices such as Residual Current Devices (RCDs) to make sure they work correctly. These are essential for preventing electric shocks. Older homes are more likely to have outdated wiring, so it is especially important to carry out checks if your property is more than 30 years old.

How Often Should You Have Testing Done?
Homeowners should have an Electrical Installation Condition Report (EICR) at least every 10 years. Landlords must have one every 5 years and provide a copy to new and existing tenants.
You should also book an inspection if you are moving into a new property, carrying out major renovations, or have not had one done in a long time. Regular checks help catch problems early before they become dangerous or expensive.

Signs You Might Need Testing Sooner
Sometimes, issues can arise before your next scheduled inspection. Watch out for warning signs such as flickering lights, a burning smell from sockets, discoloured switches, or circuit breakers that keep tripping.
These may be signs of damage or faulty wiring. If you see any of these problems, book a check as soon as possible to ensure your system is still safe. Also consider testing sooner if your home has not been inspected in the last 10 years or if you have added new electrical appliances.
What Is an EICR and Why Do You Need One?
An Electrical Installation Condition Report (EICR) is a document provided by an electrician after a full inspection. It explains whether your system is safe and lists any faults found.
The report will state whether the system is satisfactory or if repairs are needed. If problems are found, the electrician will advise what should be fixed to make the system safe. Landlords are required to carry out these checks and give tenants a copy of the report. Homeowners are not legally required to have one, but doing so is a good way to protect your home, your investment, and your family.
