    Fixed wire testing (EICR)

    Our engineers will carry out a test of all electrical services and systems throughout your building. This test includes both visual inspections and electrical tests of:

    • Hard wiring
    • Mains panels
    • Lighting
    • Sockets
    • Air conditioning
    • Distribution boards

    When does the EICR need to be carried out?

    Most companies and landlords must check their fixed electrical systems and installation as least once every 5 years. Swimming pools and gyms must be checked every 12 months.

    If it’s convenient for you, we can help you set up a maintenance schedule where 20% of the fixed installation is tested every year, at the same time as your PAT testing and emergency light testing. That way, the whole installation is tested every 5 years.

    PAT testing

    PAT testing covers portable appliances (so anything plugged in or connected to the fixed installation). This can include:

    • Computers and other hardware
    • Industrial machines
    • Kettles and toasters
    • Fridges

    Our electricians will carry out both a visual inspection of your equipment and a thorough check using specialist equipment.

    When does PAT testing need to be carried out?

    It’s recommended that PAT testing needs to be done once a year on most electrical appliances. Some equipment may need testing more frequently.

    Fire alarm testing

    A working fire alarm is a legal requirement in commercial buildings. Our fire alarm service engineers will undertake rigorous annual checks to ensure that your fire alarms are fully safe and compliant.

    When does fire alarm testing need to be done?

    Commercial businesses must get their fire alarms inspected by a competent engineer once every 6 months. In between, you’re responsible for carrying out regular tests to ensure that your fire alarm is working as it should. Our team will put together a schedule of testing to ensure your business is fully compliant with all standards.

    Emergency lighting testing

    An effective emergency lighting system is essential for providing your employees and customers with their first line of escape during an emergency. We can fully test your existing system, with any issues resolved by our team of qualified engineers or, if needed, we can install a whole new emergency lighting system.

    When does emergency lighting testing need to be done?

    Your emergency lighting should be tested by a competent engineer every 12 months, with regular monitoring completed in-house weekly or monthly.

    Communal area testing

    Communal areas include entry halls, parking areas and stairwells. Communal areas are often classed as high traffic areas and with so many people using a space it’s essential to test the circuits regularly and locate any potential wiring faults. Our experienced team will help you to:

    • Assess the communal areas of your business
    • Ensure all electrical outlets and appliances are safe and effective

    When does communal area testing need to be done?

    The fixed electrical systems and portable electrical appliances in communal areas are subject to the same regulations as in all other areas of the building. So, you’ll need annual PAT testing and emergency lighting testing, and an EICR every 5 years.
