What we do

Electrical Testing in Lincoln


We provide professional and reliable electrical testing in Lincoln and the surrounding areas

We are equipped and accredited to provide Electrical Inspection & Testing services, including final Certification & Reports.

Here is an overview of what the requirements are and how we ensure you are compliant.

  • What Electrical Testing and Certification is required and why?

    There are 3 main occasions where Electrical Testing is required:

    At Electrical Installation

    Firstly, every new electrical installation requires a qualified electrician to complete a full inspection and testing procedure. This is needed to comply with BS 7671, Regulation 610.1. Once completed, we provide you with the Electrical Installation Certificate.

    Following Electrical Alteration

    Secondly, where there is a change to an existing electrical installation, a Minor Electrical Work Certificate is completed following testing.

    As a Periodic Review

    Finally, The Electrical Condition Report is used for Periodic Inspection and Testing on existing electrical installations. This document replaces the old Periodic Inspection Report which is now not in use.

    Mayo Electrical Services are able to provide Electrical Inspection, Testing and Certification services for all of these scenarios.

  • How frequently is an Electrical Inspection carried out?

    Most standard workplace environments, including rental accommodation need an Electrical Installation Condition Report to be produced at least every 5 years. There should be routine inspections conducted at least annually.

    For Rental ‘Student’ Accommodation, it is recommended that testing be carried out with a change of tenant in case installation condition has declined over the previous tenancy.

    The frequency of periodic inspection and testing should take into account:

    • the type of installation
    • its use and operation
    • the frequency and quality of maintenance
    • the external influences to which it is subjected (such as weather)

    We can advise on the right testing frequency and approach based on the installation you have.

  • What accreditation is needed to issue Electrical Certification?

    We hold the C&G 2391 qualification and are registered with and accredited by NAPIT for inspection, testing and certification services.

    NAPIT verify annually that we are performing these services in line with current guidelines. 18th Edition Wiring Regulations certification has also been attained, to ensure we are always complying with the current regulations.


MES Portable Appliance Testing (PAT)

MES provide Portable Appliance Testing Services for both landlords and businesses.

After testing, we provide:


  • Labeling of the equipment with the Inspectors Signature, Test date, and its required re-test date;
  • A full list of any failed items, with an explanation of their failure.

We can also provide a laminated package, which includes:


  • An MES ‘Inventory’ containing each appliance type, name, location and description; and
  • A full set of test results for each appliance tested.

Following the test, we are happy to discuss your report with you and advise you of any further action required.

The Inventory can be a particularly useful documentation to have on site for External Electrical Compliance Investigator or other person interested in your compliance.

  • What is PAT (Portable Appliance Testing)?

    Electrical appliances have their safety checked through inspections and electronic tests. This is called Portable Appliance Testing. Portable Appliances are any appliances powered by inserting a plug into a socket.

  • Why do I need to have my appliances tested?

    Law requires most Public Areas to perform testing. This includes Landlords and Employers as well as spaces such as Schools, Restaurants, Gyms and Supermarkets. It also helps cover the Insurance requirements within Installations, as faulty equipment can be a Fire Risk.

  • What does Portable Appliance Testing involve?

    We carry out the test with a visual inspection and electrical test with specialist equipment. This allows us to establish the safety and suitability of your electrical appliances.

  • Who should do the work?

    A Competent Person must carry out these tests. This is someone with the necessary knowledge, skill and experience to avoid danger to themselves and others. They must be able to identify any external influences, which may have a detrimental effects on the equipment. The Electrician may also be able to ‘modify’ some of the equipment, if it did not meet up to the standards, to ‘Pass’ the Testing procedure.
