Minimum Disruption

Electrical equipment testing should not interrupt your workday. We work efficiently and flexibly to minimise operational downtime during inspection and testing.

Practical Approach

Every business environment is different. We take a practical approach, working with you to tailor our testing methods to your workplace and deliver a smooth, straightforward service from start to finish.

Testing Standards

Our testing follows the IET Code of Practice for In-Service Inspection and Testing of Electrical Equipment, 5th Edition, and BS EN 50699:2020 Recurrent Testing of Electrical Equipment, where applicable.

Risk Assessed Testing

We take a risk-based approach to electrical equipment testing, considering factors such as the type of equipment, its environment, how it is used and the associated risks rather than simply applying a fixed testing interval.

Clear Records

We provide detailed records of the equipment tested, including a unique asset number, location, make, model and serial number (where practical), together with the test results. Electronic certificates and equipment registers provide a clear record of the work carried out.

Specialist Capabilities & Legal Compliance

Fixed Electrical Equipment Inspection and Testing

Looking beyond the standard 3-pin plug to ensure comprehensive workplace safety.


We also inspect and test fixed electrical equipment, including appliances connected through fused connection units (fused spurs). Where required, this involves safe isolation before inspection and testing. Examples include hand dryers, industrial machinery and commercial kitchen extractors. The work is carried out using appropriate methods and equipment, following relevant industry guidance, including the 5th Edition of the IET Code of Practice for In-service Inspection and Testing of Electrical Equipment.

Supporting Electrical Safety Compliance

Regular inspection and testing can help manage electrical safety risks in the workplace.


If you are running a UK business or organisation, you have a legal "duty of care" to ensure your electrical equipment is safe for staff and the public. While PAT testing itself isn't explicitly, it is the easiest way to comply with the Health and Safety at Work Act 1974 and Regulation 4(2) of the Electricity at Work Regulations 1989, which states: "As may be necessary to prevent danger, all systems shall be maintained so as to prevent, so far as is reasonably practicable, such danger." Staying on top of your testing protects your team, the public and provides proof you are meeting this legal safety requirement.

Who Needs PAT / Electrical Equipment Safety Testing?

Any business or individual that provides or uses electrical equipment as part of their business has a responsibility to ensure it is safe to use. This includes not only large companies, but also self-employed workers, landlords and various other professionals, such as stonemasons, blacksmiths, artists, market traders, office cleaners, mobile hairdressers, bands, DJs and farmers. 

Electrical equipment should be appropriately inspected and maintained to help ensure it remains safe to use. PAT testing and fixed electrical equipment inspection and testing can form part of an appropriate maintenance programme, depending on the equipment, how and where it is used, and the risks involved. 

PAT testing companies such as MJ PAT Testing conduct a range of tests as part of the in-service inspection and testing of electrical equipment, including Portable Appliance Testing and the testing of fixed electrical equipment where appropriate. Testing can include equipment operating at 110V, 230V and 400V three-phase.

Venue operators and insurers may require evidence that electrical equipment is being appropriately inspected and maintained. Employers and self-employed individuals should ensure that equipment is safe for use by anyone who may come into contact with it.
